Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 9-13 and their dependent (claim 14) are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 9 indicates “the gate electrode of the first control transistor is configured to receive the second scan clock … , and the gate electrode of the second control transistor is configured to receive a fourth scan clock,” however claim 1 indicates “a gate electrode of the first control transistor is configured to receive a first scan clock … and a gate electrode of the second control transistor is configured to receive a third scan clock or the second scan clock”, therefore it is unclear if the applicant meant for the gate electrode of the first control transistor to receive either a first scan clock or a second scan clock and it is unclear if the applicant meant for the gate electrode of the second control transistor to receive either a third scan clock or the second scan clock or a fourth clock signal. Additionally the specification only mentions that the gate electrode of the first control transistor only receives one signal. Figures 9 and 10 show different implementations/embodiments where the second control transistor receives either SCLK1 or SCLKB2. With respect to Claim 10, claim 10 indicates “wherein a low section of the second scan clock is set to a width greater than a high section of the carry signal, and a high section of the second scan clock is set to a width less than a low section of the first scan clock” however claim 1 indicates, “a gate electrode of the second control transistor is configured to receive a third scan clock or the second scan clock”. Since figures 9 and 10 show different embodiments, it is unclear which scan clock signal is received by the gate electrode of the second control transistor since it can only receive one signal. The same holds true for claims 11-12 since the gate electrode of the second control transistor only receive one signal. With respect to claim 13, the claim limitations indicate “the drain electrode of the pull up transistor is configured to receive the first scan clock, the gate electrode of the first control transistor is configured to receive the second scan clock, and the gate electrode of the second control transistor is configured to receive the first scan clock” however claim 1 indicates “a gate electrode of the first control transistor is configured to receive a first scan clock, a drain electrode of the pull-up transistor is configured to receive a second scan clock, and a gate electrode of the second control transistor is configured to receive a third scan clock or the second scan clock” which contradicts what scan clock signal each transistor receives since in each embodiment a transistor receives only a single signal.

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 15-18 are rejected under 35 U.S.C. 103 as being unpatentable over Zheng as applied to claims 1 and 2 above, and further in view of Kim et al. (Pub. No.: US 2025/0022404 A1) hereinafter referred to as Kim.
With respect to Claim 15, claim 2 is incorporated, Zheng does not mention wherein the second and third control transistors include polycrystalline silicon.

With respect to Claim 16, claim 15 is incorporated, Zheng does not mention wherein the plurality of transistors in the pixel include a transistor including the polycrystalline silicon.

Therefore it would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the display apparatus of Zheng, wherein the second and third control transistors, and the transistor including the polycrystalline silicon in the pixel are P-type transistors, as taught by Kim so as to provide alternative transistor implementations.

Kim teaches a display apparatus (fig. 5, item 100: display device), comprising: a display panel (fig. 5, item 110; ¶137) including a pixel (fig. 5, item PX; ¶138), wherein the pixel includes a light emitting diode (fig. 6, item LD; ¶151) and a plurality of transistors (fig. 6, transistors within item PX = plurality of transistors) configured to be electrically connected to the light emitting diode; and a first scan driving circuit (fig. 5, item 130; ¶141-142) including, for each of a plurality of horizontal lines of the display panel, a first scan stage that is configured to output a first scan signal of the horizontal line, wherein the first scan stage (fig. 1, item 200; ¶61) includes: a pull-up transistor (fig. 1, item M13) and a pull-down transistor (fig. 1, item M14); a first control transistor (fig. 1, item M1; ¶70) and a second control transistor (fig. 1, item M2; ¶71) which are connected in parallel to each other (fig. 1), have a first electrode configured to receive a carry signal (fig. 1, item FLM; ¶196, “The first input terminal 211 receives the start signal FLM (or a scan signal GWi−1 of the previous stage circuit)”); a third control transistor (fig. 1, item M3; ¶75) and a fourth control transistor (fig. 1, item M4; ¶76) which are connected in series to each other (fig. 1); wherein a first transistor (fig. 6, item M24) is configured to connect a gate electrode of a driving transistor (fig. 6, item M21) among the plurality of transistors and a second electrode of the driving transistor in response to the first scan signal (fig. 6, item GC; ¶179), or a first transistor (fig. 6, item M23) is configured to transmit an initialization voltage (fig. 6, item Vint1) to the gate electrode of the driving transistor in response to the first scan signal (fig. 6, item GI; ¶177).
Therefore it would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the display apparatus of Zheng, wherein the first transistor is configured to connect a gate electrode of a driving transistor among the plurality of transistors and a second electrode of the driving transistor in response to the first scan signal, or the first transistor is configured to transmit an initialization voltage to the gate electrode of the driving transistor in response to the first scan signal, as taught by Kim so as to provide commonly implemented transistors in a pixel circuit.
Allowable Subject Matter
Claim 5 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.
