`The ’843 Patent: The Problem
`
`4
`
`“A liquid crystal display (LCD) has advantages . . . . However, an LCD
`does have some disadvantages. Because of the limitations of physical
`characteristics, the liquid crystal molecules need to be twisted and
`rearranged when changing input data, which can cause the images to be
`delayed. For satisfying the rapid switching requirements of multimedia
`equipment, improving the response speed of liquid crystal is desired.”

`

`The First Solution: Multiple Data Impulses
`
`5
`
`“In contrast to the prior art, the present invention discloses a driving circuit
`and relating driving method to generate two pieces of pixel data in each frame
`period for every pixel on an LCD panel and then to generate two data impulses
`according to the two pieces of pixel data and to apply them to each pixel
`within a frame period in order to change the transmission rate of a pixel
`electrode. Thus, . . . liquid crystal molecules of the pixels can twist to reach a
`predetermined gray level within a frame period, and blurring will not occur.”

`

`

`Claim 4 = The First Solution
`

`
`4. A method for driving a liquid crystal display (LCD) panel . . . comprising:
`
`receiving continuously a plurality of frame data;
`
`generating a plurality of data impulses for each pixel within every frame
`period according to the frame data; and
`
`applying the data impulses to the liquid crystal device of one of the pixels
`within one frame period via the data line connected to the pixel in order to
`control a transmission rate of the liquid crystal device of the pixel.

`

`

`Claim 1 (Not Under Review) = The Second Solution:
`Multiple Overdriven Impulses
`
`7
`
`1. A driving circuit for driving an LCD panel . . . comprising:
`
`a blur clear converter for receiving frame data every frame period, each
`frame data comprising a plurality of pixel data and each pixel data
`corresponding to a pixel, the blur clear converter delaying current frame data
`to generate delayed frame data and generating a plurality of overdriven pixel
`data within every frame period for each pixel;
`
`a source driver for generating a plurality of data impulses to each pixel
`according to the plurality of overdriven pixel data generated by the blur clear
`converter and applying the data impulses to the liquid crystal device of the
`pixel via the scan line connected to the pixel within one frame period in order
`to control transmission rate of the liquid crystal device; and
`
`a gate driver for applying a scan line voltage to the switch device of the pixel
`so that the data impulses can be applied to the liquid crystal device of the
`pixel.

`Ham’s Problem: Blurring
`
`9
`
`“[T]he conventional LCD cannot express desired color and brightness.
`Upon implementation of a moving picture, a display brightness BL fails to
`arrive at a target brightness corresponding to a change of the video data VD
`from one level to another level due to its slow response time. Accordingly, a
`motion-blurring phenomenon appears from the moving picture and a
`display quality is deteriorated in the LCD due to a reduction in a contrast
`ratio.”

`

`Ham’s Solution: Multiple Data Impulses
`
`10
`
`“The present invention discloses a method and apparatus for driving a liquid
`crystal display device suitable for enhancing a picture quality. More
`specifically, in the method and apparatus, source data is modulated based on
`registered data that is previously provided therein. The modulated data is
`applied to a liquid crystal panel at the initial period of one frame period. A
`[“Normal”] data different from the modulated data is supplied to the liquid
`crystal panel at the later period of the frame period.”

`

`Patent Owner Raises Three Arguments
`
`11
`
`“First, Petitioners’ theory of unpatentability relies on Ham’s data modulator
`52 to generate the “plurality of data impulses for each pixel within every
`frame period” as recited in claim 4.”
`
`Paper 20, Patent Owner’s Resp. at 2
`
`“Second, the Petitioners have offered no evidence on the proper
`construction of “generating” as it appears in claim 4, and therefore have
`failed to present even a de minimis showing that modulated AMdata from
`Ham’s data modulator 52 and the normal data RGB are properly
`characterized as “generat[ed].”
`
`Id. at 3-4
`
`“Third, contrary to Petitioners’ contention that “[m]ethod claims 4-9 do not
`require performing the overdrive technique,” (see Pet. at 17), claim 4
`requires overdriving.”

`The ’843 patent discloses that controlling a transmission rate of a
`from data modulator 52 and the normal data RGB from line memory 59 to the

`The Consistent Expert Testimony
`On Figure 5 Of Ham
`
`14
`
`Patent Owner’s Expert:
`
`Q. Okay. So is it correct that the initial data coming into timing
`controller is digital?
`A. It says . . . it was from a digital video -- digital video card.
`Q. And the output into data lines is analog; correct?
`A. Yeah. So let’s be clear. Yeah, converted into analog data and applied
`to the data lines, yep.

`

`Patent Owner’s Argument
`
`15
`
`“Petitioners point solely to Ham’s data modulator 52 as the element that
`allegedly ‘generates two data impulses … for each pixel within one frame
`period.’ . . . Petitioners present no other theory for Ham’s generation of the
`‘plurality of data impulses’ as required by claim 4.”

`“The output of the circuit disclosed by Ham is shown in Figure 7B
`. . . . As can be seen, each frame period is split into two halves. During the
`first half of the frame period, overdriven data is applied to each pixel.
`During the second half of the frame period, non-overdriven data is applied.”

`Patent Owner’s Proposed “Construction” Is
`Based On The Desire To Avoid Ham
`
`26
`
`“Contrary to Petitioners’ contention that ‘[m]ethod claims 4-9 do not require
`performing the overdrive technique,” claim 4 does require overdriving
`according to the proper construction of claim 4 . . . . Ham applies normal data
`RGB and therefore applies “non-overdriven data in the second half of the

`The ’843 Patent Provides Multiple
`Solutions to the Blurring Problem
`
`34
`
`“As explained in the Petition, the ’843 Patent provides multiple solutions to the problem of the
`blurring of video images in an LCD panel. (Paper 1, Petition at 12-13; Ex. 1010, Marentic Decl.
`¶84). One solution is applying two or more data impulses to a pixel within a given frame, which
`helps smooth out fast motion video and improves the image sequence the eye perceives. (Id. ¶37).
`This concept is described numerous times in the ’843 Patent without any reference to
`overdriving. (Id. ¶¶84-86).”

`Summary of Invention: Multiple Data Impulses
`
`36
`
`“Briefly, the present invention provides a method for driving an LCD panel.
`The LCD panel includes a plurality of scan lines, a plurality of data lines, and
`a plurality of pixels. Each pixel is connected to a corresponding scan line and
`a corresponding data line, and each pixel includes a liquid crystal device and
`a switching device connected to the corresponding scan line, the
`corresponding data line, and the liquid crystal device. The method includes
`receiving continuously a plurality of frame data, generating a plurality of
`data impulses for each pixel in every frame period according to the frame
`data and applying the data impulses to the liquid crystal device of one of the
`pixels within one frame period via the data line connected to the pixel in
`order to control the transmission rate of the liquid crystal device of the
`pixel.”

`Detailed Description: Multiple Data Impulses
`
`37
`
`“In contrast to the prior art, the present invention discloses a driving circuit
`and relating driving method to generate two pieces of pixel data in each
`frame period for every pixel on an LCD panel and then to generate two data
`impulses according to the two pieces of pixel data and to apply them to each
`pixel within a frame period in order to change the transmission rate of a pixel
`electrode. Thus, each of the pixels of the LCD panel is applied of a plurality
`of data impulses within a frame period, so that liquid crystal molecules of the
`pixels can twist to reach a predetermined gray level within a frame period,
`and blurring will not occur.”

`Patent Owner Contends That
`“Control a Transmission Rate” Requires Overdriving
`
`40
`
`“Petitioners’ argument that claim 4 does not require overdriving is
`tantamount to doing violence to the claim by deleting the phrase “to control
`a transmission rate of the liquid crystal device of the pixel” entirely. Such a
`result is unsupported by any expert testimony, runs contrary to Shen’s express
`… in
`and uncontested disclosure of what is meant by controlling a transmission
`rate, and further fails to give effect to all terms in the claim, according
`to the well-accepted law of claim construction.”

`

`Patent Owner’s “Definition” v. The Claim Language
`
`41
`
`Shen has explained that “overdriven” means “applying a higher or a lower
`data impulse to the pixel electrode to accelerate the reaction speed of the
`liquid crystal molecules.” . . . But Shen’s explanation is not a one-way street.
`Specifically, if “overdriven” means “applying a higher or a lower data impulse
`… in
`to the pixel electrode to accelerate the reaction speed of the liquid crystal
`molecules,” then the contrary is also true: “applying a higher or a lower data
`impulse to the pixel electrode to accelerate the reaction speed of the liquid
`crystal molecules” means “overdriving.”

`
`applying the data impulses to the liquid crystal device of one of the pixels
`within one frame period via the data line connected to the pixel in order to
`… in
`control a transmission rate of the liquid crystal device of the pixel.

`Patent Owner’s Expert Does Not Offer A
`Construction of Transmission Rate

`
`Q. Okay. Is it fair to say the transmission rate of a pixel is the percentage
`of light that it allows to pass through? . . .
`The ’843 patent discloses that controlling a transmission rate of a
`A. I’m -- I don’t think I can answer that. I don't think I can say whether
`liquid crystal device of a pixel is achieved through overdriving. Thus, the proper
`construction of claim 4’s phrase “applying the [plurality of] data impulses … in
`it’s fair or not fair. I mean, it’s -- this is the terminology that [the
`inventors] described here.

`Q. And before you--you encountered the Shen ’843 Patent, had you heard
`The ’843 patent discloses that controlling a transmission rate of a
`that term [i.e., transmission rate] used before?
`liquid crystal device of a pixel is achieved through overdriving. Thus, the proper
`construction of claim 4’s phrase “applying the [plurality of] data impulses … in

`Petitioner’s Expert Explained
`“Transmission Rate”
`
`43
`
`“In any event, based upon a correct understanding of ‘transmission rate,’
`‘control[ling] a transmission rate’ merely refers to applying a particular
`voltage (or potential difference) to a pixel's electrodes. As discussed above, this
`is part of the basic operation of every LCD drive circuit, irrespective of the
`type of display or whether or not ‘overdriving’ is used.”
