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 6 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.
As to claim 6 recites: “in the second on-pixel ratio the first pixel emits light, and the second pixel, the third pixel and the fourth pixel stop emitting”, but claim 6 depends on claim 3 which recites: “in the second on-pixel ratio, the first pixel and the second pixel emit light, and the third pixel and the fourth pixel stop emitting”. These two recitation disclose different results for the same condition, therefore it is unclear as to what happens when “in the second on-pixel ratio”. For the purpose of examination the recitation of claim 6 is interpreted as: “in the third on-pixel ratio the first pixel emits light, and the second pixel, the third pixel and the fourth pixel stop emitting”.

the data driver further outputs a pulse data voltage to the display panel (outputting the PWM DATA on the line Sig of the pixel of fig. 9 as shown in fig. 10, inherently a data driver outputs PWM DATA signal), wherein
at least one pixel of the plurality of pixels includes:
a sweep transistor (transistor 321 of fig. 9) configured to apply a first power voltage (voltage VDD of fig. 9) to a control electrode of the driving transistor (transistor 311 of fig. 9) based on the pulse data voltage (based on signal on Sig line connected to the transistor 321 of fig. 9).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Sung in view of Pyo and the teachings of Kim, such that the display apparatus was provided with pixel structure as further disclosed by Kim, with motivation to provide a display panel providing improved color reproducibility (Kim [0006]).
Allowable Subject Matter
Claims 12 and 13 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:
As to claim 12 (dependent on 11), Sung alone or in combination with other references fails to disclose the display apparatus, wherein in the second setting luminance, the pulse data voltage has a second pulse data voltage higher than a first pulse data voltage (Emphasis Added.).
As to claim 13 (dependent on 11), Sung alone or in combination with other references fails to disclose the display apparatus, wherein in the first setting, the sweep signal is gradually decreased from a first high voltage to a first low voltage, and wherein in the second setting luminance, the sweep signal is gradually decreased from a second high voltage higher than the first high voltage to the first low voltage (Emphasis Added).
