Office Action

§103
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 . Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 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, 4-6, 14-16, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Jeong et al (Publication number: US 2023/0140604) in view of Liu et al (Publication number: US 2024/0363066). Consider Claim 1, Jeong et al shows a display device (see figure 1), comprising: (a) A display panel including a plurality of pixel rows arranged in a first direction, each pixel row including a plurality of pixels (see figure 2); (See pixel unit 100). (b) A first gate driver including a first stage having a first gate signal as a first output to each of the plurality of pixel rows (see figure 2); (Read as first scan driver 210). (c) A second gate driver including a second stage having a second gate signal as a second output to each of the plurality of pixel rows, the second stage being alternately arranged with the first stage in the first direction (see figure 2; and paragraphs 60-62); (The second gate driver is read as first scan driver 220. Further, the scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS). (d) Wherein each of the first stage and the second stage is connected to at least four pixel rows among the plurality of pixel rows (see figure 2; and paragraph 61); (The scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS). However, Jeong et al does not specifically show that the first gate driver and the second gate driver share a first clock signal. In the same field of endeavor, Liu et al shows that the first gate driver and the second gate driver share a first clock signal (see figures 5 and 7; and paragraphs 71-75). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the application to incorporate the scan clock signal lines of Liu into the driving circuit of Jeong et al in order to achieve lower power consumption (see Liu et al; paragraph 3). Consider Claim 15, Jeong et al shows a gate driver (see figure 1), comprising: (a) A first gate driver including a first stage having a first gate signal as a first output to each of a plurality of pixel rows (see figure 2); (Read as first scan driver 210). (b) A second gate driver including a second stage having a second gate signal as a second output to each of the plurality of pixel rows, the second stage being alternately arranged with the first stage in a first direction (see figure 2; and paragraphs 60-62); (The second gate driver is read as first scan driver 220. Further, the scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS). (c) Wherein each of the first stage and the second stage is connected to at least four pixel rows among the plurality of pixel rows (see figure 2; and paragraph 61); (The scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS). However, Jeong et al does not specifically show that the first gate driver and the second gate driver share a first clock signal. In the same field of endeavor, Liu et al shows that the first gate driver and the second gate driver share a first clock signal (see figures 5 and 7; and paragraphs 71-75). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the application to incorporate the scan clock signal lines of Liu into the driving circuit of Jeong et al in order to achieve lower power consumption (see Liu et al; paragraph 3). Consider Claim 20, Jeong et al shows an electronic apparatus (see figure 1), comprising: (a) A processor which generates image data; and a display device which displays an image based on the image data, wherein the display device comprises: a display panel including a plurality of pixel rows arranged in a first direction and each including a plurality of pixels (see figure 2); (See pixel unit 100). (b) A first gate driver including a first stage having a first gate signal as a first output to each of the plurality of pixel rows (see figure 2); (Read as first scan driver 210). (c) A second gate driver including a second stage having a second gate signal as a second output to each of the plurality of pixel rows, the second stage being alternately arranged with the first stage in the first direction (see figure 2; and paragraphs 60-62); (The second gate driver is read as first scan driver 220. Further, the scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS). (d) Wherein each of the first stage and the second stage is connected to at least four pixel rows among the plurality of pixel rows (see figure 2; and paragraph 61); (The scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS). However, Jeong et al does not specifically show that the first gate driver and the second gate driver share a first clock signal. In the same field of endeavor, Liu et al shows that the first gate driver and the second gate driver share a first clock signal (see figures 5 and 7; and paragraphs 71-75). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the application to incorporate the scan clock signal lines of Liu into the driving circuit of Jeong et al in order to achieve lower power consumption (see Liu et al; paragraph 3). Consider Claims 4 and 16, Jeong et al shows a third gate driver including a third stage having a third gate signal as a third output to each of the plurality of pixel rows (see figure 2); (Read as third scan driver 230); a fourth gate driver including a fourth stage having a fourth gate signal as a fourth output to each of the plurality of pixel rows, the fourth stage being alternately arranged with the third stage in the first direction, wherein each of the third stage and the fourth stage is connected to at least four pixel rows among the plurality of pixel rows (see figure 2; and paragraphs 60-62); (The fourth gate driver is read as first scan driver 240. Further, the scan driver 200 may receive the first control signal SCS from the timing controller 500, and may supply a first scan signal, a second scan signal, a third scan signal, a fourth scan signal, and a fifth scan signal to first scan lines S11 to S1n, second scan lines S21 to S2n, third scan lines S31 to S3n, fourth scan lines S41 to S4n, and fifth scan lines S51 to S5n, respectively, based on the first control signal SCS); However, Jeong et al does not specifically show that the third gate driver and the fourth gate driver share a second clock signal. In the same field of endeavor, Liu et al shows that the third gate driver and the fourth gate driver share a second clock signal (see figures 5 and 7; and paragraphs 71-75). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the application to incorporate the scan clock signal lines of Liu into the driving circuit of Jeong et al in order to achieve lower power consumption (see Liu et al; paragraph 3). Consider Claim 5, Jeong et al shows that the first gate driver, the second gate driver, the third gate driver, and the fourth gate driver are positioned towards a first side of the plurality of pixel rows in a second direction crossing the first direction (see figure 2); (see the positions of first to fifth scan drivers). Consider Claim 6, Jeong et al shows that the first gate driver and the second gate driver are positioned towards a first side of the plurality of pixel rows in a second direction crossing the first direction, and wherein the third gate driver and the fourth gate driver are positioned towards a second side of the plurality of pixel rows opposite to the first side in the second direction (see figure 2); (see the positions of first to fifth scan drivers). Consider Claim 14, Jeong et al shows that each of the first stage and the second stage includes a plurality of transistors, and wherein each of the transistors is an N-type oxide semiconductor transistor (see paragraph 62). Claims 2-3 are rejected under 35 U.S.C. 103 as being unpatentable over Jeong et al (Publication number: US 2023/0140604) in view of Liu et al (Publication number: US 2024/0363066) in view of Lee et al (Publication number: US 2018/0075803). Consider Claim 2, Jeong et al does not specifically show that each of the first stage and the second stage is connected to an even number of pixel rows among the plurality of pixel rows. In the same field of endeavor, Lee et al shows that each of the first stage and the second stage is connected to an even number of pixel rows among the plurality of pixel rows (see figures 5, 6A and 6B; and paragraphs 71-74). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the application to incorporate the teaching of Lee et al into the teaching of Jeong et al and Liu et al in order to retain image quality (see Lee et al; paragraphs 3-4). Consider Claim 3, Lee et al shows that each of the first stage and the second stage is connected to four, six, or eight pixel rows among the plurality of pixel rows (see figures 5, 6A and 6B; and paragraphs 71-74). Allowable Subject Matter Claims 7-13, and 17-19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
