§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 . Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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 – 3, 7, 10 – 15, 17 – 18, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Shih et al. (U.S. PG Pub 2022/0171494) (Hereinafter referred to as Shih et al. (‘494).) in view of Shih et al. (U.S. PG Pub 2021/0224548) (Hereinafter referred to as Shih et al. (‘548).) in view of Yoo et al. (U.S. PG Pub 2020/0210043). Regarding Claim 1, Shih et al. (‘494) teach a display panel (Figure 1, Element 110. Paragraph 30), comprising a photosensitive module (Figure 1, Element 121. Paragraph 32) and a touch electrode line (Figure 1, Element not labeled, but is the line connecting the panel (Element 110) to the touch sensing circuit (Element 1221). Paragraph 30), wherein the photosensitive module (Figure 1, Element 121. Paragraph 32) comprises a photosensitive element (Figure 2, Element PD. Paragraph 33), wherein a detection signal (Figures 3 - 7B, Element FPR_EN. Paragraph 35) is applied to a first electrode of the photosensitive element (Figure 2, Element PD. Paragraph 33), the photosensitive element (Figure 2, Element PD. Paragraph 33) is configured to generate a photocurrent signal (Figure 2, Element not labeled, but is the current at Vout. Paragraph 33) according to the detection signal (Figures 3 - 7B, Element FPR_EN. Paragraph 35) and illumination (Paragraph 33), and the touch electrode line (Figure 1, Element not labeled, but is the line connecting the panel (Element 110) to the touch sensing circuit (Element 1221). Paragraph 30) is configured to transmit a touch signal (Figures 3 - 7B, Element TP. Paragraph 35); a driving stage (Figures 3 - 7B, Element DP. Paragraph 35) of the display panel (Figure 1, Element 110. Paragraph 30) comprises display stages (Figures 3 - 7B, Element DP. Paragraph 35) and vertical intermittent stages (Figures 3 - 7B, Element not labeled, but is when DP is not driven. Paragraph 35), wherein the display stages (Figures 3 - 7B, Element DP. Paragraph 35) and the vertical intermittent stages (Figures 3 - 7B, Element not labeled, but is when DP is not driven. Paragraph 35) are arranged alternately, and a vertical intermittent stage (Figures 3 - 7B, Element DP. Paragraph 35) of the vertical intermittent stages (Figures 3 - 7B, Element not labeled, but is when DP is not driven. Paragraph 35) comprises (Seen in Figures 4 – 5B and 7A – 7B) a touch stage (Figures 3 - 7B, Element TP. Paragraph 35); and in a plurality of touch stages (Figures 3 - 7B, Element TP.

(‘548) teaches wherein the second voltage and the first voltage are not identical (Figure 14, Element INF of DF2 and DF4. Paragraphs 88 – 89). It would have been obvious to a person of ordinary skill in the art to modify the teachings of the display driving of Shih et al. (‘494) with the frame periods of Shih et al. (‘548). The motivation to modify the teachings of Shih et al. (‘494) with the teachings of Shih et al. (‘548) is to improve sensor quality as much as possible, as taught by Shih et al. (‘548) (Paragraph 6).

Claims 5 - 6 inherit this objection. Claims 8 – 9 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. The following is a statement of reasons for the indication of allowable subject matter: “wherein the display stages comprise first display stages and second display stages, wherein the first display stages and the second display stages are arranged alternately; and the detection signal has the second voltage in the first display stages, and the detection signal has a third voltage in the second display stages, wherein the first voltage, the second voltage and the third voltage are not identical; wherein the second voltage is greater than the third voltage; and an absolute value of the second voltage is equal to an absolute value of the third voltage, and the second voltage and the third voltage have opposite polarities; or the third voltage is in a high-impedance state” of Claim 8 in combination with all the limitations of Claims 1 and 7, from which Claim 8 depends. Claim 9 inherits this objection. Claim 16 is 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. The following is a statement of reasons for the indication of allowable subject matter: “comprising a first detection output signal line and at least one second detection output signal line; wherein the photosensitive module comprises at least two photosensitive elements and a light shielding element, wherein the at least two photosensitive elements comprise a first photosensitive element and a second photosensitive element, wherein a second electrode of the first photosensitive element is electrically connected to the first detection output signal line, and a second electrode of the second photosensitive element is electrically connected to the at least one second detection output signal line; and the light-shielding element shields a photosensitive material layer of the first photosensitive element” of Claim 16 in combination with all the limitations of Claims 1 and 14, from which Claim 16 depends. Claim 19 is 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. The following is a statement of reasons for the indication of allowable subject matter: The prior art of record fails to teach at least “wherein the vertical intermittent stages comprise first vertical intermittent stages and second vertical intermittent stages, wherein the first vertical intermittent stages and the second vertical intermittent stages are arranged alternately; in a light detection stage in the first vertical intermittent stages, the detection signal has the second voltage, and in a light detection stage in the second vertical intermittent stages, the detection signal has a third voltage; and an absolute value of the second voltage is equal to an absolute value of the third voltage, and the second voltage and the third voltage have opposite polarities” of Claim 19 in combination with all the limitations of Claims 17 and 18, from which Claim 19 depends. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Kim et al. (U.S. PG Pub 2020/0211456) and Kim et al. (U.S. PG Pub 2020/0210044) teach a touch sensing display with phototransistors similar to the instant invention.
