PNG media_image3.png 944 970 media_image3.png Greyscale Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Lee and Jang in view of Kim et al. (US 20210272985 A1; Cited in Applicant’s IDS dated 12/28/2022), hereinafter Kim. Regarding Claim 3, Lee teaches: The display substrate according to claim 2, wherein in the second direction, a width of the first initialization signal line is different from a width of the second initialization signal line (See annotated FIG. 3B below: in DR1, a width of the first initialization signal line (labeled “1”) is different from a width of the second initialization signal line (labeled “2”)); wherein in the second direction, the width of the second initialization signal line is greater than the width of the first initialization signal line (See annotated FIG. 3B below: in DR1, the width of the second initialization signal line (labeled “2”) is greater than the width of the first initialization signal line (labeled “1”)). PNG media_image4.png 900 784 media_image4.png Greyscale Lee does not explicitly teach: wherein in the second direction, the width of the second initialization signal line is 1.3-2.4 times the width of the first initialization signal line. However, in the same field of endeavor, display devices (Kim, paragraph [0002]), Kim teaches: in a second direction, a width of a second initialization signal line (FIG. 3: 128) is 1.3-2.4 times a width of a first initialization signal line (FIG. 3: 127) (See annotated FIG. 11 below: a width of 128 (labeled “2”) is 1.3-2.4 times a width of the 127 (labeled “1”)). PNG media_image5.png 880 796 media_image5.png Greyscale Lee contained a device which differed from the claimed device by the substitution of in the second direction, the width of the second initialization signal line is greater than the width of the first initialization signal line, but not explicitly 1.3-2.4 times the width of the first initialization signal line. Kim teaches the substituted element of the width of the second initialization signal line is 1.3-2.4 times the width of the first initialization signal line. Their functions were known in the art to provide initialization voltages to the pixels. The widths of the first and second initialization signal lines taught by Lee could have been substituted with the widths of the first and second initialization signal lines as taught by Kim and the results would have been predictable and resulted in arranging the first and second initialization lines so the widths differ by a particular amount. Therefore, the claimed subject matter would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention. Claims 7-13, 20 and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Lee and Jang in view of Li et al. (US 20210384289 A1; Cited in Applicant’s IDS dated 12/28/2022), hereinafter Li. Regarding Claim 7, Lee teaches: The display substrate according to claim 6, wherein in the second direction, the reset signal line and the second initialization signal line are arranged in sequence in a direction away from the driving transistor of the mth row of sub-pixels (See annotated FIG. 3A below: in DR1, GIL_i, and the second initialization line are arranged in sequence in a direction away from the driving transistor of the ith row of sub-pixels). PNG media_image2.png 744 1371 media_image2.png Greyscale Lee does not explicitly teach (see elements emphasized in italics): wherein in the second direction, the reset signal line, the second initialization signal line, and the first initialization signal line are arranged in sequence in a direction away from the driving transistor of the mth row of sub-pixels. However, in the same field of endeavor, display devices (Li, paragraph [0002]), Li teaches: In a second direction, a second initialization signal line (R2), and a first initialization signal line (R1) are arranged in sequence in a direction away from a driving transistor (FIG. 1: Tm) of an mth row of sub-pixels (See FIG. 3: in a vertical direction, R2 and R1 are arranged in sequence in a direction away from a driving transistor of an mth row of sub-pixels). Lee contained a device which differed from the claimed device by the substitution of the second direction, the reset signal line and the second initialization signal line are arranged in sequence in a direction away from the driving transistor of the mth row of sub-pixels, but not explicitly the second direction, the reset signal line, the second initialization signal line, and the first initialization signal line are arranged in sequence in a direction away from the driving transistor of the mth row of sub-pixels. Li teaches the substituted element of the second initialization signal line, and the first initialization signal line are arranged in sequence in a direction away from the driving transistor of the mth row of sub-pixels. Their functions were known in the art to provide the first and second initialization signal lines in proximity to the pixel circuits. The relative position of the first and second initialization signal lines taught by Lee could have been substituted with the relative position of the first and second initialization signal lines, as taught by Li and the results would have been predictable and resulted in swapping the positions of VL1h and VL2h in FIG. 3A of Lee, such that the reset signal line, the second initialization signal line, and the first initialization signal line are arranged in sequence in a direction away from the driving transistor of the mth row of sub-pixels. Therefore, the claimed subject matter would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention. Regarding Claim 8, Lee teaches: The display substrate according to claim 1, wherein in a direction perpendicular to the display substrate, a driving circuit layer of each of the plurality of sub-pixels comprises a semiconductor layer (See paragraph [0167] and FIG. 5: the active areas), a first conductive layer (See paragraph [0172] and FIG. 5: conductive layer arranged on the first gate insulating layer 213), a second conductive layer (See paragraph [0207] and FIG. 7: conductive layer arranged on the second gate insulating layer 215), a third conductive layer (See paragraph [0177] and FIG. 5: conductive layer arranged on the interlayer insulating layer 217) and a fourth conductive layer disposed on the base substrate in sequence (See paragraph [0181] and FIG. 5: a conductive layer arranged on 219); and the semiconductor layer comprises an active layer of the plurality of transistors, and the active layer comprises channel regions and source-drain regions of the plurality of transistors (See paragraph [0170]); the first conductive layer comprises control electrodes of the plurality of transistors (See paragraph [0172]); the second conductive layer comprises the first initialization signal line and the second initialization signal line (See paragraph [0207] and FIG. 7: the second conductive layer comprises VL1h and VL2h); and the third conductive layer comprises a first power supply line (See paragraph [0178] and FIG. 7: the third conductive layer comprises PLv1 and PLv2). Lee does not explicitly teach: the first conductive layer comprises a reset signal line; and the fourth conductive layer comprises a second power supply line and a data signal line. However, in the same field of endeavor, display devices (Li, paragraph [0002]), Li teaches: A first conductive layer comprises a reset signal line (See FIG. 1: S1) (See paragraph [0091] and FIG. 13: S1 is located in the first metal layer M1); and a fourth conductive layer comprises a second power supply line and a data signal line (See paragraph [0091] and FIG. 13: P and D are located in the third metal layer M3). Lee contained a device which differed from the claimed device by the substitution of the first and further conductive layer, but not explicitly including a reset signal line and a second power supply line and a data signal line, respectively. Li teaches the substituted element of the first conductive layer comprises a reset signal line; and the fourth conductive layer comprises a second power supply line and a data signal line. Their functions were known in the art to provide conductive layers including the components of a pixel circuit. The first and fourth conductive layers taught by Lee could have been substituted with the first and fourth conductive layers including the claimed elements, as taught by Li and the results would have been predictable and resulted in including a reset signal line (GIL_i or GBL_i in FIG. 3A of Lee) in the first conductive layer and including a second power supply line (PLv1/PLv2 in FIG. 3A of Lee) and a data signal line (DL in FIG. 3A of Lee). Therefore, the claimed subject matter would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention. Regarding Claim 9, Lee in view of Li teaches all of the elements of the claimed invention, as stated above. Furthermore, Lee teaches: The display substrate according to claim 8, further comprising: wherein the third initialization signal line and the first initialization signal line are disposed in different layers (See FIG. 7: VL1v and VL1h are disposed in different layers), and the third initialization signal line is electrically connected with the first initialization signal line or the second initialization signal line (See FIG. 7 and paragraph [0204]: VL1v is electrically connected with VL1h via CNT8).

PNG media_image6.png 944 1008 media_image6.png Greyscale Response to Arguments Applicant’s arguments with respect to claim(s) 1, 3, 6-13, and 15-22 have been considered but are moot in view of the new ground(s) of rejection. On pages 11-12 of the Applicant’s Remarks, the Applicant argues that Lee does not teach the amended limitation. Examiner notes that the new claim elements are now addressed in the new claim rejection. Please see above for full basis of rejection.
