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.
Claim(s) 2-3 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kwak in view of Chiu et al (2005/0140642) hereinafter, Chiu.
In regards to claim 2, Kwak teaches the display device of claim 1, wherein the second display area comprises a plurality of data lines having lengths different from each other (fig. 5b data lines have different length along the curve of the circumference of the circle)[138] Kwak, and
Kwak fails to teach the second non-display area comprises a plurality of load matching units having different lengths corresponding to the lengths of the data lines of the second display area.
However, Chiu teaches teach the second non-display area comprises a plurality of load matching units having different lengths corresponding to the lengths of the data lines of the second display area.[0036-0037]
[0037] In another aspect of the present invention, the RC characteristic of adjacent data input lines can be matched by providing dummy conductor lines to the data input lines. The dummy conductor lines may be of different physical characteristics (e.g., length, width and/or thickness, or material) for different data input lines to match the RC characteristic of the data input lines. In one embodiment, the length of the dummy conductor line for each data input line is chosen to extend the data input lines to be at least as long the longest data input line. In another embodiment, the length of the dummy conductor line for each data input line is chosen to extend the data input lines to different lengths in order to match the RC characteristics in the data input lines. It is within the scope and spirit of the present invention that other physical characteristic of the dummy conductor lines may be adopted in the alternative or in addition to the length (e.g. the width, thickness and/or material) of the dummy conductor line can also be controlled to effect matching the RC characteristics of the data input lines.
It would have been obvious to one of ordinary skill in the art to modify the teachings of Kwak to further include the second non-display area comprises a plurality of load matching units having different lengths corresponding to the lengths of the data lines of the second display area as taught by Chiu in order to reduce disparity in image qualities [0036].
In regards to claim 3, Kwak in view of Chiu teaches the display device of claim 2, wherein, as a length of a data line from among the data lines becomes short, a length of the load matching unit is increased, and as the length of the load matching unit is increased, a load capacitance of the load matching unit is increased.[0036-0037] at least length Chiu
In regards to claim 16, Kwak in view of Chiu, see rational of claim 2, teaches the display device of claim 15, wherein the second display area comprises a plurality of data lines having lengths different from each other, (fig. 5b data lines have different length along the curve of the circumference of the circle)[138] Kwak and each of the plurality of load matching units includes a number of the compensation capacitors, which is different depending on the lengths of the data lines of the second display area [139-141] Kwak in view of [0036-0037] Chiu.
Claim(s) 7-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kwak in view of Bae et al (2019/0181211) hereinafter, Bae
In regards to claim 7, Kwak teaches the display device of claim 1, wherein the first non-display area comprises: a pad portion (fig. 2 pad);
Kwak fails to expressly show a plurality of first fan-out lines connected to the pad portion;
However, Bae teaches a plurality of first fan-out lines connected to the pad portion (fig. 4 (pad and fan out).
It would have been obvious to one of ordinary skill in the art to modify the teachings of Kwak to further include a plurality of first fan-out lines connected to the pad portion as taught by Bae in order to provide signals to the display and address a display.
Therefore, Kwak in view of Bae teaches and a first circuit part ((fig. 7 demux circuit) Bae) connected between the plurality of first fan-out lines and the plurality of data lines (fig. 7 DA and fanout) Bae), and the second non-display area comprises: a plurality of second fan-out lines connected to the pad portion (fig. 6 (fanout for second))Kwak; a second circuit part connected to the plurality of second fan-out lines (fig. 6 fanout); and a plurality of lead lines connected between the second circuit part and the second display area.(fig. 6 leads from 210 and 170s) Kwak and fig. 7 (demux) Bae.
In regards to claim 8, Kwak in view of Bae teaches the display device of claim 7, wherein the second circuit part comprises: a demultiplexer configured to output a data voltage received from one of the plurality of second fan-out lines to the plurality of lead lines(fig. 6 leads from 210 and 170s) Kwak and fig. 7 (demux) Bae; and a scan driver configured to generate a scan signal based on a scan control signal received from the pad portion (fig. 1 (120) scan driver) Kwak.
4. Claim(s) 12-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kwak in view of Jung et al 2019/0096978 hereinafter, Jung.
In regards to claim 12, Kwak teaches the display device of claim 11, wherein the third circuit part comprises: a scan driver configured to generate a scan signal based on a scan control signal (fig. 1 130 scan driver across from 120).; and
Kwak an antistatic circuit configured to remove static electricity flowing from the outside.
However, Jung teaches an antistatic circuit configured to remove static electricity flowing from the outside. (fig. 9 (510-530) Jung).
It would have been obvious to one of ordinary skill in the art to modify the teachings of Kwak to include an antistatic circuit configured to remove static electricity flowing from the outside as taught by Jung in order to remove static and help prevent damage.
In regards to claim 13, Kwak in view of Jung teaches, see rational of claim 12, the display device of claim 11, wherein the third circuit part comprises: a plurality of scan drivers configured to generate a scan signal based on a scan control signal (fig. 1 130 and fig. 18 103ss)) Kwak; an antistatic circuit configured to remove static electricity flowing from the outside (fig. 9 (510-530) Jung); and a plurality of load matching units connected to the plurality of data lines of the second display area.(fig. 5b CLMS)) Kwak
In regards to claim 14, Kwak in view of Jung teaches the display device of claim 13, wherein the plurality of load matching units are between the plurality of scan drivers (fig. 6 clms between 120s on bottom and 120s on top) Kwak.
