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, 6-7, 10-13, and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Lee et al. (US Patent Publication No. 2023/0419910; hereinafter Lee) in view of Hayafuji (US Patent Publication No. 2006/0202913) and Staggs (US Patent No. 4,775,857).
With reference claim 1, Lee discloses display device (100) (see paragraphs 39-40; Fig. 1), comprising:
a display panel (110) comprising sub-pixels (PX) arranged thereon (see paragraph 42; Fig. 1);
a gate driver (120, 160, 170) configured to apply a scan signal (SC) to the sub-pixels (PX) (see paragraph 43; Fig. 1); and
a controller (180) configured to sense (SS) a characteristic value of the sub-pixels (PX) (see paragraphs 45, 50; Fig. 1),
wherein the controller (180) is configured to output a first clock and a second clock (off/on clock) based on a count value that increases from an initial value during a sensing period for sensing a selected sub pixel (see paragraphs 109-111, Fig. 12), and a gate driver (120, IC) is configured to generate the scan signal (SC) based on the gate clock signal (SC_CLK) (see paragraphs 43, 47; Fig. 1);
While Lee discloses the display device and further discloses the usage of a level shifter to generate a gate clock signal (SC_clock) based on the first clock and the second clock (off/on clock), however fails to specifically disclose the gate clock signal is generated at the gate driver as recited.
Hayafuji discloses a device and method for driving wherein a level shifter (6b) is included within the gate driver (6) to provide necessary signals to the display panel (see paragraphs 47-49; Fig. 5).
Therefore it would have been obvious to one of ordinary skill in the art at the time of the invention to allow the usage of a gate driver having a level shifter similar to that which is taught by Hayafuji to thereby provide a gate driver capable of generating clock signals similar to that which is taught by Lee thereby providing an alternative configuration as well known in the art.
Further while teaching generation of necessary clock signals for driving the display panel Lee and Hayafuji fail to disclose count values for applagin signals to pixels of the display as recited.
Staggs discloses a display apparatus for displaying video wherein the controller is configured to determine the initial value of the count value to be a first value based on the selected sub-pixel is on a same pixel line as a previously sensed sub-pixel and to determine the initial value of the count value to be a second value based on the selected sub-pixel is on a different pixel line from the previously sensed sub-pixel, the first value greater than the second value (see column 6, line 17-column 7, line 11; Fig. 5).
Therefore it would have been obvious to allow the usage of a count value by the controller to determine the next line to be displayed similar to that which is taught by Staggs to be carried out in a display device similar to that which is taught by Lee and Hayafuji to thereby produce the required clocking signals for the video display generator (see Staggs; column 2, lines 61-66).
With reference to claim 2, Lee, Hayafuji, and Staggs disclose the display device of claim 1, wherein Lee further discloses wherein the controller is configured to output the first clock in response to the count value reaching a first reference count value and to output the second clock in response to the count value reaching a second reference count value (in teaching outputting SC_CLK1 in response to the over current count in the kickoff/on mode; see paragraphs 117-118, 123-124; Figs. 12-14).
With reference to claim 3, Lee, Hayafuji, and Staggs disclose the display device of claim 2, wherein Lee further discloses wherein the controller is configured to generate the gate clock signal (SC_CLK) that has a rising edge aligned with a rising edge of the first clock (SC_ON_CLK) and has a falling edge aligned with a falling edge of the second clock (SC_OFF_CLK) (see paragraphs 72-73; Fig. 4).
With reference to claim 6, Lee, Hayafuji, and Staggs, disclose the display device of claim 1, wherein Staggs further discloses that the controller sets the initial value of the count value to the first reference count value in response to the selected sub-pixel being on the same pixel line as the previously sensed sub-pixel (see column 6, line 17-column 7, line 11; Fig. 5).
With reference to claim 7, Lee, Hayafuji, and Staggs disclose the display device of claim 5, wherein Staggs further discloses that the controller is configured to initialize the count value to obtain the initial value in response to the selected sub-pixels not being on the same pixel line as the previously sensed sub-pixel (see column 6, line 17-column 7, line 11; Fig. 5).
With reference to claim 10, Lee, Hayafuji, and Staggs disclose the display device of claim 1, wherein the controller is configured to sense the characteristic value of the sub-pixels in response to a power-on signal (see paragraph 68; Figs. 1, 3).
With reference to claim 11, Lee discloses a driving method of a display device (100) including a display panel (110) on which sub-pixels (PX) are arranged (see paragraph 42; Fig. 1), a gate driver (120, 160, 170) for applying a scan signal (SC) to the sub-pixels (PX) (see paragraph 43; Fig. 1), and a controller (180) for sensing a characteristic value of the sub-pixels (PX) (see paragraphs 45, 50; Fig. 1), the method comprising:
increasing, by the controller, a count value from an initial value during a sensing period for sensing a selected sub-pixel (see paragraphs 1109-111; Fig. 12);
outputting a first clock (SC_CLK_I) in response to the count value reaching a first reference count value (IL4) (see paragraph 111; Figs. 12, 14);
outputting a second clock (SC_CLK_I) in response to the count value reaching a second reference count value (IL5) greater than the first reference count value (IL4) (paragraphs 117-119; Fig. 14).
While Lee discloses the display device and further discloses the usage of a level shifter to generate a gate clock signal (SC_clock) based on the first clock and the second clock (off/on clock), however fails to specifically disclose the gate clock signal is generated at the gate driver as recited.
Hayafuji discloses a device and method for driving wherein a level shifter (6b) is included within the gate driver (6) to provide necessary signals to the display panel (see paragraphs 47-49; Fig. 5).
Therefore it would have been obvious to one of ordinary skill in the art at the time of the invention to allow the usage of a gate driver having a level shifter similar to that which is taught by Hayafuji to thereby provide a gate driver capable of generating clock signals similar to that which is taught by Lee thereby providing an alternative configuration as well known in the art.
Further while teaching generation of necessary clock signals for driving the display panel Lee and Hayafuji fail to disclose count values for applagin signals to pixels of the display as recited.
Staggs discloses a display apparatus for displaying video wherein the initial value of the count value is determined by the controller to be a first value based on the selected sub-pixel is on a same pixel line as previously sensed sub-pixel and to be a second value based on the selected sub-pixel is on a different pixel line from the previously sensed sub-pixel, the first value grater than the second value (see column 6, line 17-column 7, line 11; Fig. 5).
Therefore it would have been obvious to allow the usage of a count value by the controller to determine the next line to be displayed similar to that which is taught by Staggs to be carried out in a display device similar to that which is taught by Lee and Hayafuji to thereby produce the required clocking signals for the video display generator (see Staggs; column 2, lines 61-66).
With reference to claim 12, Lee, Hayafuji, and Staggs disclose the display device of claim 11, wherein Staggs further discloses wherein the determining, before the increasing the count value, whether the selected sub-pixel is on a same pixel line as the previously sensed sub-pixel; and setting the first value of the initial value of the count value to the first reference count value in response to the selected sub-pixel being on the same pixel line as the previously sensed sub-pixel (see column 6, line 17-column 7, line 11; Fig. 5).
With reference to claim 13, Lee, Hayafuji, and Staggs disclose the display device of claim 12, wherein Staggs further discloses initializing the count value to obtain the second value of the initial value in response to the selected sub-pixel being not on the same pixel line as the previously sensed sub-pixel (see column 6, line 17-column 7, line 11; Fig. 5).
With reference to claim 15, Lee, Hayafuji, and Staggs disclose the display device of claim 11, wherein Lee further discloses that the sensing of the characteristic value of the sub-pixels is performed in response to a power-on signal (see paragraph 68; Figs. 1, 3).
Claims 4, 8-9, and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Lee, Hayafuji, and Staggs as applied to claim 1 or 11 above, and further in view of Jeon et al. (US Patent Publication No. 2020/0243007; hereinafter Jeon).
With reference to claim 4, Lee, Hayafuji, and Staggs disclose the display device of claim 2, however fails to disclose sensing the sub-pixels as recited.

Therefore it would have been obvious to one of ordinary skill in the art to allow the usage of a sequential sensing unit similar to that which is taught by Jeon to be carried out in a system similar to that which is taught by Lee, Hayafuji, and Staggs to thereby improve degradation of pixels in the display panel (see Jeon; paragraph 57).
With reference to claims 8 and 14, Lee, Hayafuji, Staggs, and Jeon disclose the display device of claim 4 or 11, wherein Jeon further discloses that the controller (130) comprises a memory (LUT) configured to store information on a pixel line of the selected sub pixel (in teaching compensation data; see paragraph 57).
