DETAILED ACTION
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 .
Response to Amendment
1. Amendments filed on 03/17/2026 have been entered. Claims 1, 5, 15-16 and 19 have been amended and claim 6 has been canceled.
Response to Arguments
2. Applicant contends that Cho does not disclose or suggest “wherein at least some of the pixels that are located on a same vertical line and different horizontal lines and emit light of a same color among the plurality of pixels are connected to a same scan line and are driven in sub-frames of a frame such that, during a given sub-frame period, each of the data lines supplying those pixels is supplied with a data signal corresponding to a single color” Examiner respectfully disagrees. The prior art by Cho at least teaches some of the limitations. Please see the updated office action below. However, Cho does not teach driving pixels in the sub-frames period. Driving pixels based on sub-frame periods is well known in the art. For example, the newly applied prior art by Bae describes ([0079], fig. 4) that driving the odd data lines in the first sub-frame period followed by the even data lines in the second sub-frame period.
Allowable Subject Matter
3. Claims 1-5, 7-14 and 19-20 are allowed.
The following is an examiner’s statement of reasons for allowance: The prior art of record alone or in combination, fails to teach or render obvious, “A display device comprising: pixels arranged in an order of a first red pixel, a first green pixel, a first blue pixel, and a second green pixel on a first horizontal line; pixels arranged in the order of a second blue pixel, a third green pixel, a second red pixel, and a fourth green pixel on a second horizontal line, and a fifth green pixel located on a same vertical line as the second green pixel and the fourth green pixel, wherein the second green pixel and the fifth green pixel are connected to a same scan line, wherein the first red pixel and the second blue pixel located on a same vertical line are connected to different data lines, and wherein the first green pixel and the second green pixel located on the first horizontal line are connected to different scan lines” in combination with the other claimed limitations set forth in claim 1.
The prior art of record alone or in combination, fails to teach or render obvious, “An electronic device comprising: a display device; and a power source to supply power to the display device, wherein the display device includes: a plurality of pixels; a data driver configured to output color data signals; a distributor configured to provide the color data signals to data lines connected to the plurality of pixels, wherein the plurality of pixels are to be driven in an interlaced scanning pattern, and wherein the plurality of pixels include: pixels arranged in an order of a first red pixel, a first green pixel, a first blue pixel, and a second green pixel on a first horizontal line, the first red pixel, the first blue pixel, and the second green pixel configured to emit light during a first sub-frame period; and pixels arranged in the order of a second blue pixel, a third green pixel, a second red pixel, and a fourth green pixel on a second horizontal line, the first green pixel, the second blue pixel, the third green pixel and the second red pixel configured to emit light during a second sub- frame period, wherein the first red pixel and the second blue pixel located on a same vertical line are connected to different data lines, wherein the first green pixel and the second green pixel located on the first horizontal line are connected to different scan lines, wherein the first red pixel and the first green pixel are connected to a first data line wherein the first blue pixel and the third green pixel are connected to a second data line, wherein the second red pixel and the fourth green pixel are connected to a third data line, and wherein the second green pixel is connected to a fourth data line” in combination with the other claimed limitations set forth in claim 19.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
4. Claim(s) 15-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kim (US 2017/0076665) in view of Cho et al (US 2014/0210868) and further in view of Bae et al (US 2016/0217754).
As to claim 15, Kim teaches a display device comprising:
pixels connected to scan lines and data lines (Fig. 2);
a scan driver configured to drive the scan lines (scan driver 20, fig. 1, [0026]);
a data driver configured to supply a plurality of data signals to output lines (data driver 30, fig. 1, [0027]); and
a data distributor connected to the output lines and configured to supply the plurality of data signals in time division to the data lines (demux circuit 40, fig. 2, [0028]),
wherein the pixels located on a same vertical line and emit light of different colors (pixels R and B in the first vertical line, fig. 2) are alternately connected to different data lines (data lines D1 and D2, fig. 2), and
Kim does not teach wherein at least some of the pixels that are located on a same vertical line and different horizontal lines and emit light of a same color among the pixels are connected to a same scan line and are driven in sub-frames of a frame such that, during a given sub-frame period, each of the data lines supplying those pixels is supplied with a data signal corresponding to a single color.
However, Cho teaches wherein at least some of the pixels (G11 and G21, fig. 4) that are located on a same vertical line ((2b)th pixel column, fig. 4) and different horizontal lines ((2d-1)th pixel row and ((2d)th pixel row, fig. 4) and emit light of a same color (green, fig. 4) among the pixels are connected to a same scan line (GL2, fig. 4) and are driven in (as shown in fig. 4, both G11 and G12 are driven at the same time and connected to the same gate line GL2 ) such that, during a given (when GL2 is activated, fig. 4), each of the data lines (DL2 and DL3, fig. 4) supplying those pixels (G11 and G21, fig. 4) is supplied with a data signal corresponding to a single color ([0044] The TFT Tr of the green pixel G11 in the second pixel column and the first pixel row is electrically connected to the second gate line GL2 and the second data line DL2, and the TFT Tr of the green pixel G21 in the second pixel column and the second pixel row is electrically connected to the second gate line GL2 and the third data line DL3)
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Kim to teach, the pixel configuration and connections with data and scan lines, as suggested by Cho. The motivation would have been in order to provide a display device in which “adjacent pixels share the gate line, and adjacent pixels share the data line. As a result, an area for the TFT is reduced in comparison to the related art LCD device such that the aperture ratio and the transmittance in the pixel are improved” ([0058]).
Kim in view of Cho does not teach driving pixels in the sub-frames period of a frame as claimed.
However, Bae teaches driving a pixel in the sub-frames period of a frame ([0079] During the first sub-frame period, a first level data voltage Lv1 corresponding to a maximum gray-scale level may be applied to the first, third, fifth, and seventh data lines D1, D3, D5, and D7. Of the data voltages applied during the first sub-frame period, data voltages applied during an ON-period of a gate signal applied to the first gate line G1 are applied to first type pixels in the first pixel row PR1_O. Of the data voltages applied during the first sub-frame period, data voltages applied during an ON-period of a gate signal applied to the third gate line G3 are applied to first type pixels included in the third pixel row PR3_O, [0081] During the second sub-frame period, a first level data voltage Lv1 corresponding to a maximum gray-scale level may be applied to the second, fourth, and sixth data lines D2, D4, and D6. Of the data voltages applied during the second sub-frame period, data voltages applied during an ON-period of a gate signal applied to the second gate line G2 are applied to second type pixels in the second pixel row PR2_E. Of the data voltages applied during the second sub-frame period, data voltages applied during an ON-period of a gate signal applied to the fourth gate line G4 are applied to second type pixels in the fourth pixel row PR4_E, fig. 4).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Kim and Cho to teach, driving a pixel in the sub-frames period of a frame, as suggested by Bae. The motivation would have been in order provide a driving method “capable of reducing the output frequency of a data driver and thus reducing power consumption” ([0006]).
As to claim 16, Kim does not teach the display device as claimed.
However, Cho teaches the display device, wherein the at least some of the pixels that emit light of the same color are green pixels (G11 and G12, fig. 4), and the green pixels located on a same horizontal line ((2d-1)th pixel row, fig. 4) are alternately connected to different scan lines (fig. 4 illustrates that G11 is connected GL2 and G12 is connected to GL1).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Kim to teach, pixels’ configuration and connections with data and scan lines, as suggested by Cho. The motivation would have been in order to provide a display device in which “adjacent pixels share the gate line, and adjacent pixels share the data line. As a result, an area for the TFT is reduced in comparison to the related art LCD device such that the aperture ratio and the transmittance in the pixel are improved” ([0058]).
As to claim 17, Kim in view of Cho does not teach the display device as claimed.
However, Bae teaches the display device, wherein the frame is divided into a first sub- frame (first sub-frame period, fig. 4) and a second sub-frame (second sub-frame period, fig. 4), and wherein the scan driver sequentially supplies an enable scan signal to odd- numbered scan lines (G1 and G3, fig. 4) during a first sub-frame period (first sub-frame period, fig. 4), and sequentially supplies an enable scan signal to even-numbered scan lines (G2 and G4, fig. 2) during a second sub-frame period (second sub-frame period, fig. 4)
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Kim and Cho to teach, the display device, as suggested by Bae. The motivation would have been in order provide a driving method “capable of reducing the output frequency of a data driver and thus reducing power consumption” ([0006]).
As to claim 18, Kim in view of Cho and further in view of Bae teaches the display device, wherein: the data distributor has a demultiplexer (Kim: demux circuit 40, fig. 2) connected between one output line (Kim: for example, a line connected to the source channels SC1 of fig. 2) and two data lines (Kim: D2 and D10, fig. 2), and the demultiplexer sequentially connects the one output line to the two data lines during a horizontal period in response to an enable first control signal and an enable second control signal (Kim: signals CS1 and CS2, fig. 3), and wherein the display device further comprises: a timing controller (Kim: timing controller 50, fig. 1) configured to supply the enable first control signal and the enable second control signal (Kim: [0028] The demux circuit 40 selectively connects the data lines D1 to Dm with the source channels SC1 to SCj in response to a demux control signals CSx, fig. 1), wherein the timing controller: sequentially supplies the enable first control signal and the enable second control signal for each horizontal period (Kim: [0028], figs. 1, 2, and 3), or changes an order in which the enable first control signal and the enable second control signal are supplied for each horizontal period.
