`
`DETAILED ACTION
`
`Notice of Pre-AIA or AIA Status
`
`1.
`
`The present application, filed on or after March 16, 2013, is being examined under the
`
`first inventor to file provisions of the AIA.
`
`Information Disclosure Statement
`
`2.
`
`The information disclosure statement (IDS) submitted on 08/13/2018 is being considered
`
`by the examiner.
`
`Drawings
`
`3.
`
`The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they
`
`include the following reference character(s) not mentioned in the description: the reference “DA”
`
`in figure 2. Corrected drawing sheets in compliance with 37 CFR 1.121(d), or amendment to the
`
`specification to add the reference character(s) in the description in compliance with 37 CFR
`
`1.121(b) are required in reply to the Office action to avoid abandonment of the application. Any
`
`amended replacement drawing sheet should include all of the figures appearing on the immediate
`
`prior version of the sheet, even if only one figure is being amended. Each drawing sheet
`
`submitted after the filing date of an application must be labeled in the top margin as either
`
`“Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not
`
`accepted by the examiner, the applicant will be notified and informed of any required corrective
`
`action in the next Office action. The objection to the drawings will not be held in abeyance.

`
`Claim Objections
`
`4.
`
`Claims 1 and 7 are objected to because of the following informalities: Claim 1 recites
`
`“the first sub—area comprises at least one first pixel unit, the at least one first pixel unit
`
`comprising: a first pixel configured to display a first color; a second pixel configured to display a
`
`second color; and a third pixel configured to display a third colors”. Claim 1 further recites “the
`
`second sub—area comprises at least one second pixel unit, the at least one second pixel unit
`
`comprising: the first pixel, the second pixel, and the third pixel”. The second sub—area is disposed
`
`to adjoin and to surround the first sub—area. Therefore, the first, second and third pixels of the
`
`second pixel unit seem to be different from the first, second and third pixels of the first pixel
`
`unit. However, claim states the second pixel unit comprising the first pixel, the second pixel and
`
`the third pixel, which are claimed as comprised by the first pixel unit as well. Appropriate
`
`correction is required to clear the above issue. Claim 7 suffers from the same problem as
`
`described above.
`
`Claim Rejections - 35 US C § 103
`
`5.
`
`In the event the determination of the status of the application as subject to AIA 35 USC.
`
`102 and 103 (or as subject to pre—AIA 35 USC. 102 and 103) is incorrect, any correction of the
`
`statutory basis for the rejection will not be considered a new ground of rejection if the prior art
`
`relied upon, and the rationale supporting the rejection, would be the same under either status.
`
`6.
`
`The following is a quotation of 35 USC. 103 which forms the basis for all obviousness
`
`rejections set forth in this Office action:
`
`A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not
`identically disclosed as set forth in section 102, if the differences between the claimed invention and the
`prior art are such that the claimed invention as a whole would have been obvious before the effective
`filing date of the claimed invention to a person having ordinary skill in the art to which the claimed
`invention pertains. Patentability shall not be negated by the manner in which the invention was made.

`
`Claims 1-3, 6-8 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over
`
`Hickl et al. (US. Pub. No. 2016/0366379, hereinafter “Hickl”) in View of Yuan et al. (US. Pub.
`
`No. 2016/0178940, hereinafter “Yuan”).
`
`As to claim 1, Hickl discloses a Video wall—type display deVice [figure 2, a Video wall—
`
`type display deVice, paragraph 94, display wall] comprising:
`
`a plurality of display modules [figure 2, multiple display modules], each of the display
`
`modules comprising:
`
`a display area [figure 2, display area within dashed lines, paragraph 5] comprising: a first
`
`sub—area [figure 2, the center pixels, i.e., pixels in the top row, columns 2 and 3]; and at least one
`
`second sub—area [figure 2, the pixels surround the first sub—area] disposed to adjoin and to
`
`surround the first sub—area; and
`
`a non—display area [figure 2, non—display area outside the dashed lines surrounding the
`
`display area, paragraph 5] disposed to surround the display area,
`
`wherein the first sub—area comprises at least one first pixel unit, the at least one first pixel
`
`unit comprising:
`
`a first pixel [figure 2, first pixel displays “R” color] configured to display a first color;
`
`a second pixel [figure 2, second pixel displays “G” color] configured to display a second
`
`color; and
`
`a third pixel [figure 2, third pixel displays “B” color] configured to display a third colors,
`
`the first, second, and third colors being different from each another [figure 2, the colors are
`
`different from each other], and
`
`wherein the second sub—area comprises at least one second pixel unit, the at least one
`
`second pixel unit comprising:
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 5
`
`the first pixel, the second pixel, and the third pixel [figure 2, first pixel “G”, second pixel
`
`“R” and third pixel “B”].
`
`Hickl does not disclose at least one fourth pixel configured to display a white color.
`
`Yuan teaches a display device [abstract] comprising: a display area [figure 2A, “21” and
`
`“22”] comprising a first sub—area [figure 2A, central display region “22”]; and at least one second
`
`sub—area [figure 2A, peripheral display region “21” adjoin and surround “22”] disposed to adjoin
`
`and to surround the first sub—area; wherein the second sub—area comprises at least one second
`
`pixel unit, the at least one second pixel unit comprising: the first pixel [figure 6, first pixel “R”],
`
`the second pixel [figure 6, second pixel “G”] and the third pixel [figure 6, third pixel “B”]; and at
`
`least one fourth pixel configured to display a white color [figure 6, fourth pixel “W”].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to have the second pixel to comprise at least one fourth pixel configured to display a white color,
`
`as taught by Yuan, in order to improve quality of the color filter substrate and enhance visual
`
`effects of the display device (Yuan, paragraph 62).
`
`As to claim 2, Hickl, as modified by Yuan discloses the video wall—type display device
`
`of claim 1, wherein the at least one fourth pixel of the at least one second pixel unit is disposed
`
`to adjoin the non—display area [Yuan, figure 6, the “W” pixel of the second pixel unit is disposed
`
`to adjoin the non—display area “64”]. In addition, the same rationale is used as in rejection for
`
`claim 1.
`
`As to claim 3, Hickl, as modified by Yuan discloses the video wall—type display device of
`
`claim 2, wherein the at least one fourth pixel of the at least one second pixel unit is disposed
`
`between the first pixel, the second pixel, and the third pixel of the at least one second pixel unit
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 6
`
`and the non—display area [Yuan, figure 6, “W” pixel is disposed between the non—display area
`
`“64” and the three pixels]. In addition, the same rationale is used as in rejection for claim 1.
`
`As to claim 6, Hickl, as modified by Yuan discloses the video wall—type display device
`
`of claim 1, wherein the first color is a red color, the second color is a green color, and the third
`
`color is a blue color [Hickl, figure 2, “RGB”, Yuan, figure 6].
`
`As to claim 7, Hickl discloses a video wall—type display device [figure 2, a video wall—
`
`type display device, paragraph 94, display wall] comprising:
`
`a plurality of display modules [figure 2, multiple display modules], each of the display
`
`modules comprising:
`
`a display area [figure 2, display area within dashed lines, paragraph 5] configured to
`
`display an image; and
`
`a non—display area [figure 2, non—display area outside the dashed lines surrounding the
`
`display area, paragraph 5] disposed to surround the display area,
`
`wherein the display area comprises:
`
`a first sub—area [figure 2, the center pixels, i.e., pixels in the top row, columns 2 and 3]
`
`comprising at least one first pixel unit;
`
`a second sub—area [figure 2, the pixels adjoin the lower side of the top pixels] comprising
`
`at least one second pixel unit disposed to adjoin a lower side of the first sub—area;
`
`a third sub—area [figure 2, the pixels adjoin the left side of the top pixels] comprising at
`
`least one third pixel unit disposed to adjoin a left side of the first sub—area;
`
`a fourth sub—area [figure 2, the pixels adjoin the right side of the top pixels] comprising at
`
`least one fourth pixel unit disposed to adjoin a right side of the first sub—area; and
`
`wherein the at least one first pixel unit comprises:
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 7
`
`a first pixel [figure 2, first pixel displays “R” color] configured to display a first color;
`
`a second pixel [figure 2, second pixel displays “G” color] configured to display a second
`
`color; and
`
`a third pixel [figure 2, third pixel displays “B” color] configured to display a third color,
`
`the first, second, and third colors being different from one another [figure 2, the colors are
`
`different from each other], and
`
`wherein each of the at least one second pixel unit, the at least one third pixel unit, and the
`
`at least one fourth pixel unit comprises:
`
`the first pixel, the second pixel, and the third pixel [figure 2, first pixel “G”, second pixel
`
`“R” and third pixel “B”].
`
`Hickl does not disclose a fifth sub—area comprising at least one fifth pixel unit disposed to
`
`adjoin an upper side of the first sub—area,
`
`wherein each of the at least one second pixel unit, the at least one third pixel unit, the at
`
`least one fourth pixel unit, and the at least one fifth pixel unit comprises:
`
`the first pixel, the second pixel, and the third pixel; and
`
`at least one fourth pixel configured to display a white color.
`
`Yuan teaches a fifth sub—area [figure 2A, the top sub—area disposed to adjoin the upper
`
`side of the central sub—area “22”] comprising at least one fifth pixel unit disposed to adjoin an
`
`upper side of a first sub—area,
`
`wherein each of at least one second pixel unit, at least one third pixel unit, at least one
`
`fourth pixel unit, and at least one fifth pixel unit comprises:
`
`a first pixel [figure 6, first pixel “R”], the second pixel [figure 6, second pixel “G”] and
`
`the third pixel [figure 6, third pixel “B”]; and
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 8
`
`at least one fourth pixel configured to display a white color [figure 6, fourth pixel “W”,
`
`paragraph 60].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to dispose a fifth sub—area comprising at least one fifth pixel unit on the upper side of the central
`
`area, wherein each of at least one second pixel unit, at least one third pixel unit, at least one
`
`fourth pixel unit, and at least one fifth pixel unit comprises: a first pixel, the second pixel and the
`
`third pixel; and at least one fourth pixel configured to display a white color, as taught by Yuan,
`
`in order to improve quality of the color filter substrate and enhance visual effects of the display
`
`device (Yuan, paragraph 62).
`
`As to claim 8, Hickl, as modified by Yuan discloses the video wall—type display device
`
`of claim 7, except for wherein the at least one fourth pixel is disposed to adjoin a lower side of
`
`the second sub—area, a left side of the third sub—area, a right side of the fourth sub—area, and an
`
`upper side of the fifth sub—area. However, Yuan teaches the at least one fourth pixel is disposed
`
`at different position of a pixel unit [figure 6, “W” pixel can be located at the right side of a sub—
`
`area, the left side of a sub—area or the middle of a sub—area]. It would have been obvious to one
`
`having ordinary skill in the art before the effective filing date of the invention to dispose the at
`
`least one fourth pixel to adjoin a lower side of the second sub—area, a left side of the third sub—
`
`area, a right side of the fourth sub—area, and an upper side of the fifth sub—area, since it has been
`
`held that rearranging parts of an— invention involves only routine skill in the art. In re Japikse, 86
`
`USPQ 70.

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 9
`
`As to claim 20, Hickl, as modified by Yuan discloses the video wall—type display
`
`device of claim 7, wherein the first color is a red color, the second color is a green color, and the
`
`third color is a blue color [HickL figure 2, “RGB”, Yuan, figure 6].
`
`8.
`
`Claims 4, 5, 9-15, 18 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable
`
`over Hickl in view of Yuan, as applied to claim 1 above, further in view of Kim et al. (US. Pub.
`
`No. 2013/0027439, hereinafter “Kim”).
`
`As to claim 4, Hickl, as modified by Yuan discloses the video wall—type display device
`
`of claim 1.
`
`Hickl, as modified by Yuan does not disclose wherein each of the first pixel, the second
`
`pixel, and the third pixel of the at least one first pixel unit includes two sub—pixels, which display
`
`different brightness, respectively.
`
`Kim teaches a display device with a plurality of pixels [figure 3, a plurality of pixels],
`
`wherein each of a first pixel, a second pixel, and a third pixel of at least one first pixel unit
`
`includes two sub—pixels [figure 3, each pixel “SPX” includes two sub—pixels “SPEl” and
`
`“SPE2”], which display different brightness, respectively [paragraph 86, the brightness level of
`
`“SPEl” is higher than the brightness level of “SPE2”].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to divide each of the first pixel, the second pixel and the third pixel of the at least one first pixel
`
`unit into two sub—pixels, which display different brightness, respectively, as taught by Kim, in
`
`order to improve the viewing angle of the 2D image displayed (Kim, paragraph 86).
`
`As to claim 5, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 4, except for wherein the first pixel, the second pixel, and the third pixel
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 10
`
`of the at least one second pixel unit are configured to display the same brightness. It would have
`
`been obvious to one having ordinary skill in the art before the effective filing date of the
`
`invention to have the first pixel, the second pixel, and the third pixel of the at least one second
`
`pixel unit to display the same brightness, since it has been held that where the general conditions
`
`of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves
`
`only routine skill in the art. In re Aller, 105 USPQ 233.
`
`As to claim 9, Hickl, as modified by Yuan discloses the video wall—type display device
`
`of claim 8.
`
`Hickl, as modified by Yuan does not disclose wherein the first pixel, the second pixel,
`
`and the third pixel of the at least one first pixel unit are arranged in two rows and three columns,
`
`and
`
`wherein the first pixel, the second pixel, the third pixel, and the fourth pixel of the at least
`
`one second pixel unit, the at least one third pixel unit, the at least one fourth pixel unit, and the at
`
`least one fifth pixel unit are arranged in two rows and three columns.
`
`Kim teaches a first pixel, a second pixel, and a third pixel of at least one first pixel unit
`
`are arranged in two rows and three columns, and
`
`wherein the first pixel, the second pixel, the third pixel, and the fourth pixel of the at least
`
`one second pixel unit, the at least one third pixel unit, the at least one fourth pixel unit, and the at
`
`least one fifth pixel unit are arranged in two rows and three columns [figure 3, the pixels “PX”
`
`are arranged in two rows and three columns].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to arrange a first pixel, a second pixel, and a third pixel of at least one first pixel unit are
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 11
`
`arranged in two rows and three columns, and wherein the first pixel, the second pixel, the third
`
`pixel, and the fourth pixel of the at least one second pixel unit, the at least one third pixel unit,
`
`the at least one fourth pixel unit, and the at least one fifth pixel unit are arranged in two rows and
`
`three columns, as taught by Kim, in order to improve the viewing angle of the 2D image
`
`displayed (Kim, paragraph 86).
`
`As to claim 10, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 9, wherein the first pixel, the second pixel, and the third pixel of the at
`
`least one second pixel unit are sequentially arranged in a first row, and
`
`wherein the at least one fourth pixel of the at least one second pixel unit is sequentially
`
`arranged in a second row [Kim, figure 3, first to third pixels in the first row and fourth pixel in
`
`the second row]. In addition, the same rationale is used as in rejection for claim 9.
`
`As to claim 11, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 10, except for wherein the at least one fourth pixel of the at least one
`
`second pixel unit has the same brightness as the first pixel, the second pixel, and the third pixel
`
`disposed in their respective columns. It would have been obvious to one having ordinary skill in
`
`the art before the effective filing date of the invention to have the at least one fourth pixel of the
`
`at least one second pixel unit with the same brightness as the first pixel, the second pixel, and the
`
`third pixel disposed in their respective columns, since it has been held that where the general
`
`conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges
`
`involves only routine skill in the art. In re Aller, 105 USPQ 233.
`
`As to claim 12, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 9, wherein the at least one third pixel unit, the at least one fourth pixel of
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 12
`
`the at least one third pixel unit is sequentially disposed in a first column [Kim, figure 3, “SPEl”
`
`is disposed in first column], and
`
`wherein the first pixel, the second pixel, and the third pixel of the at least one third pixel
`
`unit are disposed in second and third columns [Kim, figure 3, three pixels disposed in second and
`
`third columns]. In addition, the same rationale is used as in rejection for claim 9.
`
`As to claim 13, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 9, except for wherein the at least one fourth pixel of the at least one third
`
`pixel unit has the same brightness as the first pixel, the second pixel, and the third pixel adjoined
`
`to them in their respective rows. It would have been obvious to one having ordinary skill in the
`
`art before the effective filing date of the invention to have the at least one fourth pixel of the at
`
`least one third pixel unit with the same brightness as the first pixel, the second pixel, and the
`
`third pixel adjoined to them in their respective rows, since it has been held that where the general
`
`conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges
`
`involves only routine skill in the art. In re Aller, 105 USPQ 233.
`
`As to claim 14, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 9, wherein the first pixel, the second pixel, and the third pixel of the at
`
`least one fourth pixel unit are disposed in first and second columns [Kim, figure 3, the four
`
`pixels disposed in first and second columns], and
`
`wherein the at least one fourth pixel of the at least one fourth pixel unit is sequentially
`
`disposed in a third column [Kim, figure 3]. In addition, the same rationale is used as in rejection
`
`for claim 9.
`
`As to claim 15, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 9, wherein the at least one fourth pixel of the at least one fifth pixel unit
`
`

`

`Application/Control Number: 16/102,615
`Art Unit: 2622
`
`Page 13
`
`is sequentially disposed in a first row [Kim, figure 3, fourth pixel and fifth pixel is sequentially
`
`disposed in a first row], and
`
`wherein the first pixel, the second pixel, and the third pixel of the at least one fifth pixel
`
`unit are disposed in a second row [Kim, figure 3, first to third pixels are disposed in a second
`
`row]. In addition, the same rationale is used as in rejection for claim 9.
`
`As to claim 18, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 7.
`
`Hickl, as modified by Yuan does not disclose wherein each of the first pixel, the second
`
`pixel, and the third pixel of the at least one first pixel unit includes two sub—pixels, which display
`
`different brightness.
`
`Kim teaches a display device with a plurality of pixels [figure 3, a plurality of pixels],
`
`wherein each of a first pixel, a second pixel, and a third pixel of at least one first pixel unit
`
`includes two sub—pixels [figure 3, each pixel “SPX” includes two sub—pixels “SPEl” and
`
`“SPE2”], which display different brightness [paragraph 86, the brightness level of “SPEl” is
`
`higher than the brightness level of “SPE2”].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to divide each of the first pixel, the second pixel and the third pixel of the at least one first pixel
`
`unit into two sub—pixels, which display different brightness, as taught by Kim, in order to
`
`improve the viewing angle of the 2D image displayed (Kim, paragraph 86).
`
`As to claim 19, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 18, except for wherein each of the first pixel, the second pixel, and the
`
`third pixel of each of the at least one second pixel unit, the at least one third pixel unit, the at
`
`

`

`Application/Control Number: 16/ 102,615
`Art Unit: 2622
`
`Page 14
`
`least one fourth pixel unit, and the at least one fifth pixel unit comprises at least one sub—pixel,
`
`which displays a single brightness. It would have been obvious to one having ordinary skill in
`
`the art before the effective filing date of the invention to have each of the first pixel, the second
`
`pixel, and the third pixel of each of the at least one second pixel unit, the at least one third pixel
`
`unit, the at least one fourth pixel unit, and the at least one fifth pixel unit comprise at least one
`
`sub—pixel, which displays a single brightness, since it has been held that where the general
`
`conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges
`
`involves only routine skill in the art. In re Aller, 105 USPQ 233.
`
`9.
`
`Claim 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hickl in view of
`
`Yuan, further in view of Kim, further in view of Aratani et al. (US. Patent No. 6,014,121,
`
`hereinafter “Aratani”).
`
`As to claim 16, Hickl, as modified by Yuan and Kim discloses the video wall—type
`
`display device of claim 9.
`
`Hickl, as modified by Yuan and Kim does not disclose wherein areas occupied by the
`
`first pixel, the second pixel, the third pixel, and the fourth pixel disposed in the first row of each
`
`of the at least one first pixel unit, the at least one second pixel unit, the at least one third pixel
`
`unit, and the at least one fourth pixel unit are larger than areas occupied by the first pixel, the
`
`second pixel, the third pixel, and the fourth pixel disposed in the second row of each of the at
`
`least one first pixel unit, the at least one second pixel unit, the at least one third pixel unit, and
`
`the at least one fourth pixel unit, respectively.
`
`Aratani teaches a display device wherein areas occupied by a first pixel, a second pixel, a
`
`third pixel, and a fourth pixel disposed in the first row of each of at least one first pixel unit, at
`
`least one second pixel unit, at least one third pixel unit, and at least one fourth pixel unit are
`
`

`

`Application/Control Number: 16/ 102,615
`Art Unit: 2622
`
`Page 15
`
`larger than areas occupied by the first pixel, the second pixel, the third pixel, and the fourth pixel
`
`disposed in the second row of each of the at least one first pixel unit, the at least one second pixel
`
`unit, the at least one third pixel unit, and the at least one fourth pixel unit, respectively [figure 1,
`
`the areas occupied by the four pixels in the first row are larger than the areas occupied by the
`
`four pixels in the second row].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to have the areas occupied by a first pixel, a second pixel, a third pixel, and a fourth pixel
`
`disposed in the first row of each of at least one pixel unit larger than areas occupied by the first
`
`pixel, the second pixel, the third pixel, and the fourth pixel disposed in the second row of each of
`
`the at least one pixel unit, respectively, which display different brightness, as taught by Aratani,
`
`in order to display a picture at different resolution levels without causing image quality
`
`deterioration (Aratani, abstract).

`
`Claim 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hickl in view of
`
`Yuan, further in view of Kim, further in view of Aratani, further in view of Baek et al. (US. Pub.
`
`No. 2014/0211103, hereinafter “Baek”).
`
`As to claim 17, Hickl, as modified by Yuan, Kim and Aratani discloses the video wall—
`
`type display device of claim 16.
`
`Hickl, as modified by Yuan, Kim and Aratani does not disclose wherein areas occupied
`
`by the first pixel, the second pixel, the third pixel, and the fourth pixel disposed in the first row
`
`of the at least one fifth pixel unit are smaller than areas occupied by the first pixel, the second
`
`pixel, the third pixel, and the fourth pixel disposed in the second row of the at least one fifth
`
`pixel unit, respectively.
`
`

`
`Baek teaches a display device wherein areas occupied by a first pixel, a second pixel, a
`
`third pixel, and a fourth pixel disposed in a first row of at least one pixel unit are smaller than
`
`areas occupied by the first pixel, the second pixel, the third pixel, and the fourth pixel disposed in
`
`a second row of the at least one pixel unit, respectively [figure 5, the areas occupied by the four
`
`pixels in the first row are smaller than the areas occupied by the four pixels in the second row].
`
`Therefore, it would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the invention to have modified the video wall—type display device of Hickl
`
`to have the areas occupied by a first pixel, a second pixel, a third pixel, and a fourth pixel
`
`disposed in the first row of each of at least one pixel unit smaller than areas occupied by the first
`
`pixel, the second pixel, the third pixel, and the fourth pixel disposed in the second row of each of
`
`the at least one pixel unit, respectively, which display different brightness, as taught by Baek, in
`
`order to avoid deterioration
