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 .
Claims 1, 10, and 13 are amended. Claims 3-4, 8, and 15-16 are cancelled. Currently claims 1-2, 5-7, 9-14, and 17-25 are under review.
Response to Arguments
Applicant's arguments filed July 23, 2026 have been fully considered but they are not persuasive. The Applicant argues on page 8 of the remarks that the reference Choi statically elongates the vertical blank period to a fixed length and merely executes a pre-programmed delay before stepping up the common voltage. The Applicant argues at the top of page 9 of the remarks that Choi’s blanking interval is fixed and known in advance and therefore Choi cannot teach “timing a vertical blanking interval having a variable duration”.
The Office disagrees. The instant specification is silent as to how a vertical blanking interval has a variable duration in a current frame. Paragraph 39 of the instant specification indicates “a compensation value used to compensate for the brightness of the display panel during the vertical blanking interval in the current frame is determined in real time during the vertical blanking interval in the current frame” and paragraph 49 indicates “the vertical blanking interval Vblank in the current frame may alternatively be timed in any other appropriate manner”, none of which indicates that the vertical blanking interval has a variable duration in a current frame. Figure 3 of the instant application shows that the vertical blanking interval has a variable duration among frames, not in a current frame.
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “timing module” in claim 13, “first value determining module” in claim 13, and “second value determining module” in claim 14.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
Paragraph 86 indicates “The modules and/or units included in the apparatus may be implemented in various manners, including software, hardware, firmware, or any combination thereof… example types of hardware logic components that may be used include a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), an application-specific standard part (ASSP), a system on chip (SoC), a complex programmable logic device (CPLD), and the like”.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 1 and 13 and their dependents (claims 2, 5-7, 9-12, 14, 17-25) are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The claim limitations require “timing a vertical blanking interval having a variable duration in a current frame on the display panel”. Paragraph 39 of the instant specification indicates “a compensation value used to compensate for the brightness of the display panel during the vertical blanking interval in the current frame is determined in real time during the vertical blanking interval in the current frame” and paragraph 49 indicates “the vertical blanking interval Vblank in the current frame may alternatively be timed in any other appropriate manner”, none of which indicates that the vertical blanking interval has a variable duration in a current frame. Figure 3 of the instant application shows that the vertical blanking interval has a variable duration among frames, not in a current frame. Therefore the claim limitations “timing a vertical blanking interval having a variable duration in a current frame on the display panel” are not described in the figures or the specification and for the purposes of examination will be interpreted as “a vertical blanking interval having a variable duration among frames in the display panel”.

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.

With respect to Claim 18, claim 17 is incorporated, Choi does not explicitly teach wherein the drive signal comprises at least one of the following: an array common (ACOM) voltage signal or a shared common (SVCM) voltage signal.

Liao teaches an electronic apparatus (fig. 1, item LCD panel; ¶77, “LCD TV”), wherein the electronic apparatus comprises: a timing module (fig. 1, item 100: timing controller; ¶25), configured to time a vertical blanking interval on a display panel (fig. 2; ¶28); and a first value determining module (fig. 1, item 110; ¶37-38), configured to determine, a first analog value used to perform first analog compensation on brightness of the display panel by adjusting a common voltage signal during the vertical blanking interval in the current frame (¶38, “When the refresh rate is lower than the fixed refresh rate F1, the timing controller 100 increases the first common voltage Acom outputted by the power module 200 according to the corresponding control instructions. When the refresh rate is lower, the first common voltage Acom is greater”); wherein the common voltage signal comprises at least one of an array common (ACOM) voltage signal (¶25; ¶29; ¶31, “a first common voltage Acom to the first common electrode layer”; ¶35), wherein the ACOM voltage signal is connected to lower plates of all subpixel storage capacitors on an array side (fig. 4, lower plate of Cst is connected to Acom; ¶30, “The first electrode plate of the storage capacitor Cst is connected to the first common electrode layer of the array substrate”; ¶31, “a first common voltage Acom to the first common electrode layer”), and wherein the adjusting the common voltage signal compensates for current leakage of the subpixel storage capacitors during the vertical blanking interval (¶4, “FreeSync adjusts the refresh rate of the display through changing the vertical blanking interval (Vblank). However, during the vertical blanking interval, the liquid crystal still has leakage currents”; ¶32; ¶35, “the first common voltage Acom could be adjusted to be increased to dynamically improve or eliminate the issues of low voltage of the pixel electrode. This improves or eliminates the issues of the luminance difference ΔLum in different refresh rates or flickers”).
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 electronic apparatus of Choi, wherein the common voltage signal comprises at least one of an array common (ACOM) voltage signal, wherein the ACOM voltage signal is connected to lower plates of all subpixel storage capacitors on an array side, and wherein the adjusting the common voltage signal compensates for current leakage of the subpixel storage capacitors during the vertical blanking interval, as taught by Liao so as to improve or eliminate the issues of the luminance difference in different refresh rates or flickers (¶35).

Therefore it would have been obvious to a person of ordinary skill in the art to modify the method of Choi, to incorporate the idea of performing brightness compensation during a vertical active interval such that adjusting the common voltage replaces luminance correction values, resulting in wherein the method further comprises: determining, in response to that the timing time of the vertical blanking interval reaches the second threshold time, a second value used to perform second compensation on the brightness of the display panel during the vertical blanking interval in the current frame, wherein the second compensation is later than the first compensation, as taught by Koo1 so as to provide a display device capable of improving a luminance deviation according to a variation of the vertical blank period (¶8).
