Regarding claim 1, Kim’834 discloses a display device (10), (fig. 1, [0064]), comprising:

However, Kim’834 does not mention a first-color demultiplexer configured to electrically connect the first data line and the third data line to a first-color data output.

However, Kim’834 does not mention a data driver having first through third color output lines for first through third colors of pixels, respectively.
In a similar field of endeavor, Kwak teaches:
a data driver (300) having first through third-color output lines (O1 to Om-1) for first through third-colors of pixels (R, G and B subpixels), respectively, (fig. 1, [0032 and 0046]);
wherein the first pixel array (subpixels of columns 1-2) includes first-color pixels (B) connected to the first data line (D2), second-color pixels (G) connected to the second data line (D3), and third-color pixels (R) connected to the zeroth data line (D1),
wherein the second pixel array (subpixels of columns 3-4) includes first-color pixels (B) connected to the third data line (D4), second-color pixels (G) connected to the fourth data line (D5) through transistors MA2 and MC2, and third-color pixels (R) connected to the fifth data line (D6) through transistors MC2 and MA2,
wherein the third pixel array (subpixels of columns 5-6) includes first-color pixels (B) connected to the third data line (D4) through transistors MCm-1 and MB2, second color pixels (G) connected to the sixth data line (D3m-5) through transistors MAm-1 and MBm-1, and third-color pixels (R) connected to the fifth data line (D6) through transistors MBm-1 and MA2, (fig. 1, [0035 and 0049-0055]).
Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Kim’834, by specifically providing the data driver having first through third-color output lines for first through third colors of pixels, as taught by Kwak, for the purpose of improving resolution, [0011].
However, Kim’834 in view of Kwak does not mention wherein the first output line is exclusively connectable to the first-color pixels.
In a similar field of endeavor, Yang teaches
wherein the first output line (SC1) is exclusively connectable to the first-color pixels (R), the second output line (SC2) is exclusively connectable to the second color pixels (G), and the third output line (SC3) is exclusively connectable to the third color pixels (B), (fig. 4, [0083-0085]).
Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Kim’834 in view of Kwak, by specifically providing the first output line is exclusively connectable to the first color pixels, as taught by Yang, for the purpose of preventing a coupling between data lines without a dummy source channel, [0005].
However, Kim’834 in view of Kwak and in view of Yang does not mention wherein each of the second-color pixels of the second pixel array is connected to the fifth data line through the pixel contact and the connection wire, wherein the connection wire overlaps the fourth data line.
In a similar field of endeavor, Li teaches
wherein each of the second-color pixels (i.e. green pixels G in the third column) of the second pixel array (i.e. pixel array of the third column) includes a connection wire and a pixel contact (i.e. connection line connecting the pixel to the data line D5),
wherein each of the second-color pixels (G) of the second pixel array (i.e. pixel array of the third column) is connected to the fifth data line (D5) through the pixel contact and the connection wire,
wherein the connection wire overlaps the fourth data line (i.e. green pixel G is connected to data line D5 and overlaps the fourth data line D4), (fig. 4, [0056]).
Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Kim’834 in view of Kwak and in view of Yang, by specifically providing the connection wire overlaps the fourth data line, as taught by Li, for the purpose of improving the display effects of the display panel, [0032].
Regarding claim 24, Kim’834 discloses wherein the first-color pixels, the second-color pixels and the third-color pixels (R, G and B subpixels) connected to respective data lines (DL1 and DL2) are directly connected to said data lines (i.e. subpixels R and B are directly connected to data line DL1 and subpixels G are directly connected to data line DL2),
wherein no more than one data line extending in the second direction (Y direction) is disposed between each pair of adjacent pixel arrays (i.e. second and third columns of subpixels only has one data line DL2 disposed between) in the first direction (X direction), (fig. 10).
However, Kim’834 does not mention wherein the demultiplexer consists of a first-color demultiplexer configured to exclusively receive, demultiplex and transmit data of a first color.
In a similar field of endeavor, Yang teaches
wherein the demultiplexer (120) consists of a first-color demultiplexer (i.e. switch SWS1 connected to data line RDL1 and switch SWS3 connected to data line LDL3) configured to exclusively receive, demultiplex and transmit data of a first color (red subpixels R), a second-color demultiplexer (i.e. switch SWS4 connected to data line LDL5 and switch SWS2 connected to data line RDL7) configured to exclusively receive, demultiplex and transmit data of a second color (blue subpixels B), and a third-color demultiplexer (i.e. switch SWS1 connected to data line LDL2 and switch SWS4 connected to data line RDL4) configured to exclusively receive, demultiplex and transmit data of a third color (green subpixels G),
wherein each of the substantially same plurality of data lines is a single-color data line configured to exclusively conduct data of a single color (i.e. for example, switch SWS1 connected to data line RDL1 and switch SWS3 connected to data line LDL3 transmit data of red color), (fig. 4, [0080-0084]).
Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Kim’834 in view of Kwak, by specifically providing the first, second and third color demultiplexers, as taught by Yang, for the purpose of preventing a coupling between data lines without a dummy source channel, [0005].
Response to Arguments
Applicant’s arguments with respect to claim(s) 1, 14 and 23 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
In view of amendment, the reference of Li has been added for new grounds of rejection.
