`
`REMARKS/ARGUMENTS
`
`Claims 1-19 are in the present application, of which claims 1, 3, 5, 8, 11, and 12
`
`are independent. Claims 1, 3, 5, 8, and 11 are amended herein, and claims 16-19 are
`
`added herein. Claims 12-14 were previously withdrawn. The amendments to claims 1,
`
`3, 5, 8, and 11 find full support throughout the application as filed, at least at paragraphs
`
`[0105], [0115], [0176], and [0211] (as published) and FIGS. 1B, 4B, 4C, 6, 9, and 12. The
`
`amendmentsto claim 11 and new claims 16-19 find full support throughout the application
`
`as filed, at least at paragraph [0185] (as published) and FIGS. 6, 9, and 12. No new
`
`matter has been introduced. Applicant
`
`respectfully requests reconsideration and
`
`allowanceof claims 1-11 and consideration on the merits and allowance of claims 16-19.
`
`l.
`
`Claim Rejections under 35 U.S.C. § 112
`
`Claims 1, 3, 5 and 11 were rejected under 35 U.S.C. § 112(a) as allegedly failing
`
`to comply with the written description requirement.
`n
`tt
`
`In particular, the Office action alleges
`
`that
`
`the recitations of “transistors,”
`
`“a substrate supporting ...
`
`transistors,” and “a
`
`fingerprint sensor disposed under the substrate ... and in a different
`
`layer than the
`
`transistors” lack written description support in the application asfiled.
`
`First, regarding “transistors” and “a substrate supporting ...
`
`transistors,” each
`
`independentclaim recites “pixels,” and as the specification describes, each pixel includes
`
`“a thin film transistor.” See, e.g., paragraphs [0125], [0126], and [0133] (as published)
`
`(“The pixels according to exemplary embodiments include at least one first pixel PX1 ...
`
`and at least one second pixel PX2”, “Eachofthe first pixels PX1 includes at least onefirst
`
`sub-pixel,” and “The first sub-pixel according to exemplary embodiments mayinclude an
`
`insulating layer, a pixel definition layer PDL, a thin film transistor TFT, a light emitting
`
`element, and a cover layer CV disposed on the substrate SUB.”)
`
`In other words, as
`
`explained in the specification, each pixel includes sub-pixels, and each sub-pixel includes
`
`a transistor.
`
`Thus, by reciting “pixels,” it
`
`is
`
`implicit and/or inherent
`
`that multiple
`
`“transistors” would be present because, at a minimum, eachpixel includes one transistor.

`
`See MPEP § 2163(1)(B) (describing that claims and claim limitations may be “supported
`
`in the specification through express, implicit, or inherent disclosure’).
`
`Asto “a substrate supporting ... transistors,” the Office action concedes that the
`
`specification describes “a substrate supporting pixels.” Office action, page 4. Thus, for
`
`the same reasoning as set forth above, namely that each pixel includes at least one
`
`transistor, because the specification describes “a substrate supporting pixels,” the
`
`specification implicitly and/or inherently describes “a substrate supporting transistors”
`
`becausethe transistors are part of the pixels.
`
`Lastly, as to “a fingerprint sensor disposed under the substrate ... and in a different
`
`layer than the transistors,” claims 1, 3, 5, 8, and 11 have been amendedherein to recite
`
`“a fingerprint sensor disposed uAder on a rear surface of the substrate” (amendments
`
`shown) for consistency with the Office action’s interpretation of the specification.
`
`Nevertheless, at least Figure 4B (reproduced below) shows a non-limiting example of the
`
`fingerprint sensor (FPS) disposed under the substrate (SUB), which is the same as being
`
`on a rear surface of the substrate (SUB), and in a different layer than the transistors (TFT).
`
`See MPEP § 2163(II)(A)(3)(a)
`
`(“An applicant may show that
`
`the inventor was in
`
`possession of an invention by disclosure of drawings or structural chemical formulas that
`
`are sufficiently detailed to show that the inventor was in possession of the claimed
`
`invention as a whole.”).

`
`Accordingly, in view of the amendments and above remarks, Applicant respectfully
`
`requests that the rejection of claims 1, 3, 5, and 11 under 35 U.S.C. § 112(a) be
`
`withdrawn.
`
`ll.
`
`Claim Rejections under 35 U.S.C. § 102(a)
`
`Claims 1-11 and 15 were rejected under 35 U.S.C. § 102(a)(1) as allegedly being
`
`anticipated by Bae et al. (U.S. Pub. No. 2016/0266695, hereinafter “Bae’).
`
`Claim 1
`
`is amended herein and nowrecites (emphasis added):
`
`A display device comprising:
`a display panel
`including a substrate supporting pixels and
`transistors to display an image, the display panel includingafirst area and
`a second area;
`a fingerprint sensor disposed on a rear surface of the substratein
`the first area and in a different layer than the transistors;
`a touch sensor to sense a touch position according to a touch of a
`user on the display panel in the first area and the second area;
`a_sensor control circuit to control an operation of the fingerprint
`sensorby sensing light variation or ultrasonic wave variation and the touch
`sensor by sensing capacitance; and
`a display driving circuit to control an image display operation of the
`display panel by generating an image driving signal,
`wherein the sensor control circuit is configured to drive the touch
`sensorand the fingerprint sensor sequentially or simultaneously, and
`wherein the first area is enclosed by the second areain a plan view.
`
`As best Applicant understands, the Office action equates the “image scanning
`
`function” as generally described at paragraphs [0067] and [0068] of Bae with both the
`
`“fingerprint sensor’ and the “touch sensor” as recited in claims 1, 3, 5, 8, and 11. See
`
`Office action, pages 5 and 6. Although Applicant does not agree that the “image scanning
`
`function” described in Bae can reasonably be equated with both the fingerprint sensor
`
`and the touch sensor as recited, Applicant respectfully notes that, because Bae describes
`
`only a single “image scanning function,” Bae does not disclose at least “a sensor control
`
`circuit
`
`to control an operation of the fingerprint sensor by sensing light variation or
`
`ultrasonic wavevariation and the touch sensor by sensing capacitance”as recited in claim
`
`1 and as similarly recited in claims 3, 5, and 8.

`124612154.2

`
`

`

`App. No.: 17/391 ,056
`Reply responsiveto final Office Action dated April 10, 2024
`
`For example, Bae appears to provide its “image scanning function” by using “an
`
`optical sensor” that “may senselight emitted from the display surface and reflected from
`
`a surface of the finger F, but may also sense ambientlight passing through the finger F
`
`and incident to the display surface.” Bae, paragraph [0069]. Bae does notdiscloseeither:
`
`1) that the image sensing function can be achieved by sensing capacitance; or 2) that the
`
`display apparatus
`
`includes a separate touch sensor
`
`that operates by sensing
`
`capacitance.
`
`Indeed, in rejecting the above-quote feature of claim 1, the Office action merely
`
`states “Referring to FIG. 20, an optical sensor 100 included in a cell array 10 includes a
`
`plurality of transistors, a photodiode, and a capacitance (Cap)’. Office action, page 6.
`
`This passage appears to merely be describing the components of the optical sensor and
`
`does not disclose “a sensor control circuit to control an operation of the fingerprint sensor
`
`by sensing light variation or ultrasonic wave variation and the touch sensor by sensing
`
`capacitance”asrecited.
`
`Further, this capacitor/capacitance is merely a component of the optical sensor
`
`100 and supports the function of the optical sensor 100, which is controlled by sensing
`
`light, not by sensing capacitance. See, e.g., Bae, FIG. 20 and paragraph [0137] (showing
`
`the capacitor/capacitance CAP as merely one componentof the optical sensor 100 and
`
`describing that “[t]he received reflected light is converted to an electrical signal in the
`
`photodiode (pin), amplified by gm times through the amplification transistor (AMP gm),
`
`and output as sensing data (lout) through the output transistor (READ) when a read-out
`
`enable signal is applied.”).
`
`In other words, Bae does not describe controlling an operation
`
`of the image sensing function by “sensing capacitance” from or in any way related to the
`
`capacitor/capacitance Cap.
`
`Bae describes, at most, a fingerprint sensor and a sensor control circuit to control
`
`an operation of the fingerprint sensor by sensing light variation but does not also disclose
`
`at least “a touch sensor” and “a sensor control circuit to control an operation of ... the

`

`

`App. No.: 17/391 ,056
`Reply responsiveto final Office Action dated April 10, 2024
`
`touch sensor by sensing capacitance” as recited in claim 1 and as similarly recited in
`
`claims 3, 5, and 8.
`
`Further, the Office action does not address the feature of “a fingerprint sensor
`
`disposed under the substrate,” now recited as “a fingerprint sensor disposed on a rear
`
`surface of the substrate” in each of claims 1, 3, 5, 8, and 11. At most, the Office action
`
`alleges that “the optical sensor may be disposed on or below the TFT,” but this is
`
`unrelated to whether or not the optical sensor is “under” or “on a rear surface of’ the
`
`substrate.
`
`Additionally, claim 11 is amended herein and now recites (emphasis added):
`
`A display device comprising:
`a display panel
`including a substrate supporting pixels and
`transistors to display an image, the display panel includingafirst area and
`a second area;
`a fingerprint sensor disposed on a rear surface of the substrate in the
`first area and in a different layer than the transistors;
`a touch sensor disposed on a front surface of the substrate to sense
`a touch position according to a touch of a user on the display panel in the
`first area and the second area:
`a sensor control circuit to control an operation of the fingerprint
`sensorby sensing light variation or ultrasonic wave variation; and
`a display driving circuit to control an image display operation of the
`display panel by generating an image driving signal,
`wherein the first area is enclosed by the second areain a plan view.
`
`New claims 16-19 recite features similar to the above-underlined features of claim 11.
`
`As explained above with respect to the rejection of claim 1,
`
`the Office action
`
`appears to equate the “image scanning function” of Bae with both the fingerprint sensor
`
`and the touch sensor as recited. Applicant respectfully submits that this equationis invalid
`
`becausethe “image scanning function” cannot reasonably be considered to be both on a
`
`rear surface and on a front surface of the substrate.
`
`Accordingly, Applicant respectfully submits that Bae fails to disclose at least the
`
`above-discussed features of amended claims 1, 3, 5, 8, and 11. As such, Applicant
`
`respectfully submits that claims 1, 3, 5, 8, and 11 are patentably distinguishable over Bae

`
`and respectfully requests that the rejection of claims 1, 3, 5, 8, and 11 be withdrawn and
`
`that these claims be allowed.
`
`Moreover, because claims 2, 4, 6, 7, 9, 10, and 16-19 each depend, directly or
`
`indirectly, from one of claims 1, 3, 5, 8, and 11, these claims each incorporate all the
`
`terms and features of their respective base claim, in addition to other terms and features,
`
`which together further patentably distinguish these claims over the art of record.
`
`Therefore, Applicant respectfully requests that the rejections of claims 2, 4, 6, 7, 9, and

`10 be withdrawn and that claims 2, 4, 6, 7, 9, 10, and 16-19 be allowed as well.
