Claim Interpretation
Claim 1 comprises limitation “in each unit frame period, a non-light-emitting state is set in at least one of an initial sub-frame period and a last sub-frame period”; Examiner interprets the claims limitation as conjunctive requiring both of the elements i.e. a non-light-emitting state in an initial sub-frame period and also in a last sub-frame period. If applicant doesn’t agree and wants the claim limitation to be interpreted as disjunctive, please amend to claims language to replace and with or.
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: “a driver configured to drive the pixel array; and a controller configured to control the driver, wherein the controller is configured to control the driver such that each of a plurality of unit frame periods includes a plurality of sub-frame periods and a duty ratio in each sub-frame period is controlled” in claim 1.
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. Par 0034 describes “FIG. 1 is a view showing an example of the configuration of a display device 10 according to this embodiment. The display device 10 can include a pixel array 12, a vertical scanning circuit 13 and a signal output circuit 14 which serve as a driver 50 configured to drive the pixel array 12, and a controller 20 configured to drive the driver 50. It can be said that the vertical scanning circuit 13 and the signal output circuit 14 form the driver 50 configured to drive the pixel array 12”. Par 0042 describes “The controller 20 can include a timing generator (TG) 30 and a receiver 40. The receiver 40 can receive a luminance setting signal and supply it to the TG 30.”
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 § 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.

Since pixel capacitance 38 accumulates the charge corresponding to the signal voltage, drive transistor 33 supplies the gate-source current corresponding to the signal voltage to light-emitting device 32 and causes light-emitting device 32 to emit light);
Therefore, it would have been obvious to one having ordinary skill in the art to modify the invention disclosed by LEE to incorporate the teachings of ISHII to start each subframe with light emission period while varying the total number of frame period irrespective of a frame period that is input in order to make flicker invisible on the display panel for displaying an image.
