Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant's arguments filed 9/8/2026 have been fully considered but they are not persuasive. Regarding the rejection of claim 1, the Applicant argues [Remarks: pg. 11, 1st para. – pg. 14, 1st para.], that “II. Chang does not disclose that the over-driving voltage value table stores voltage values applied to electrodes of a sub-pixel, as required by amended claim 1 Amended claim 1 recites, among other limitations, that the over-driving voltage value table comprises a plurality of initial grayscale values and a plurality of target grayscale values corresponding to each other, and further recites that the over-driving voltage values stored in the over-driving voltage value table are voltage values applied to electrodes of the sub-pixel to drive a liquid crystal layer of the sub-pixel. As shown in FIG. 2 of the present application, reproduced below, the liquid crystal display panel of the present application comprises an array substrate layer 10 including a plurality of sub- pixel electrodes 102, a color filter substrate layer 20, and a liquid crystal layer 30 disposed between the array substrate layer 10 and the color filter substrate layer 20, the liquid crystal layer 30 comprising a plurality of liquid crystal units 301 each corresponding to one of the sub-pixel electrodes 102. As described in the present specification, the over-driving voltage value stored in the over-driving voltage value table is understood as a voltage directly or indirectly applied to the sub-pixel electrode 102 to drive the liquid crystal molecules in the corresponding liquid crystal unit 301. The values themselves that are stored in the claimed over-driving voltage value table are therefore voltage magnitudes, not merely digital grayscale codes awaiting further conversion. Chang does not disclose a table that stores voltage values in this sense. Paragraph [0181] of Chang expressly states that "TABLE 1 shows exemplary modified image signals for pairs of previous image signals gN-1 and current image signals gN in a 256 gray system." The values recorded in Table 1 of Chang are therefore, by the express language of Chang, modified image signals, that is, digital grayscale-domain codes within a 256-gray system, rather than voltage magnitudes. This reading is confirmed by the structure of the image signal modifier 650 described in paragraphs [0189] through [0192] of Chang. The LUT 641 outputs reference modified image signals f, and the calculator 643 outputs a modified image signal gN' to the data driver 500. Paragraph [0193] of Chang states that "the data driver 500 of the image signal modifier applies a data voltage to the pixel PX, which is greater or less than a target data voltage." The generation and application of an actual voltage is therefore performed downstream of the LUT 641 and the calculator 643, by the data driver 500 in conjunction with the gray voltage generator 800 shown in FIG. 1 of Chang, using the same conversion mechanism that is applied to every pixel PX regardless of whether the corresponding image signal was modified by the signal converter 640. The LUT 641 and Table 1 of Chang therefore store and output grayscale-domain image signals, not the voltage values that are ultimately applied to a pixel electrode. Paragraph [0194] of Chang further supports this reading. Paragraph [0194] states that "[t]he example shown above with respect to TABLE 1 does not modify a current image signal having the highest gray of 255 or the lowest gray of zero such that a target data voltage corresponding thereto is applied." That is, even where Chang describes a relationship between a gray value and an applied voltage, the applied voltage is described as being generated by applying the ordinary, unmodified image signal to the ordinary data-voltage generation process performed by the data driver 500, rather than being stored within Table 1 or the LUT 641 itself. Because Chang does not disclose that the values stored in its lookup table are voltage values applied to the electrodes of a sub-pixel to drive a liquid crystal layer, Chang does not disclose each and every element of amended claim 1, and Chang does not anticipate amended claim 1 under 35 U.S.C. 102(a)(1). III. Amended claim 1 recites additional structure not separately addressed by the rejection Amended claim 1 further recites that the initial grayscale values comprise a third initial grayscale value and a fourth initial grayscale value both less than the second target grayscale values, wherein the third initial grayscale value is less than the fourth initial grayscale value, and that the over-driving voltage values corresponding to the third initial grayscale value and the second target grayscale values are greater than the over-driving voltage values corresponding to the fourth initial grayscale value and the second target grayscale values. This recitation further particularizes the over-driving voltage value table required by amended claim 1, in combination with the other limitations of amended claim 1 discussed above, including the requirement that the values stored in that table be voltage values applied to the electrodes of the sub-pixel. For at least the reasons set forth above, amended claim 1 is not anticipated by Chang.” The Office respectfully disagrees. In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., that an over-driving voltage table comprising over-driving voltage magnitudes [Remarks: pg. 12, 1st – last para.]) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Refer to table 1 & table 2 & paragraph 210 of Chang. In table 1 of Chang an over-driving value is selected corresponding to the intersection in table 1 between an initial grayscale value of a previous frame (gn-1) and a target grayscale value of a current frame (frame gn), such that to reach the desired target grayscale value of the current frame, an over-driving value is utilized for the current frame (gn’). The selected over-driving value represents a corresponding over-driving voltage, see table 2 & para. 210, (for example gray 255 being equal to 6 volts & gray 0 being equal to 0 volts) which teaches in the relation between grays [grayscales] & gray voltages. Regarding amendments to claim 1, refer to office action below in light of table 1 & table 2 of Chang. Thus, Chang teaches independent claim 1. Regarding the rejection of claim 6, the Applicant argues [Remarks: pg. 14, 2nd – 3rd para.], that “amended claim 6 is allowable for similar reasons”. The Office respectfully disagrees. Refer to response to claim 1 above. Further, refer to office action below regarding amendments to claim 6 in light of table 1 & table 2 of Chang. Thus, Chang teaches amended independent claim 6. Regarding the rejection of claim 15, the Applicant argues [Remarks: pg. 14, last para.], that “claim 15 is allowable by virtue of its dependency on amended claim 6”. The Office respectfully disagrees. Refer to response to claims 1 & 6 above. Thus, Chang teaches claim 15. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
