In addition, the source driver 206 may include a first switch 311a that is connected to an output terminal of the first amplifier 311 and a second switch 312a that is connected to an output terminal of the second amplifier 312.”)

In addition, the source driver 206 may include a first switch 321a that is connected to an output terminal of the first amplifier 321 and a second switch 322a that is connected to an output terminal of the second amplifier 322.”)
a plurality of first output pads configured to output the first channel signal and the second channel signal; a plurality of second output pads configured to output the third channel signal; (Bae, [0064], “Pads connected to the output terminals of the amplifiers of the source driver 206 may be disposed on one side of the display panel 160, for example, at one end of each channel of the pentile source lines.”)
a plurality of first channel lines connected between the plurality of first output pads and the plurality of first source amplifiers; and a plurality of second channel lines connected between the plurality of second output pads and the plurality of second source amplifiers, (Bae, [0065], “In the first pixel 161, the source driver 206 may include, for example, a first amplifier 311 supplying a signal to a first channel and a second amplifier 312 supplying a signal to a second channel among the pentile source lines. In addition, the source driver 206 may include a first switch 311a that is connected to an output terminal of the first amplifier 311 and a second switch 312a that is connected to an output terminal of the second amplifier 312.”)
wherein a first first channel line and a second first channel line among the plurality of first channel lines are connected to each other, and a first second channel line and a second second channel line among the plurality of second channel lines are connected to each other; wherein the display driving device further comprises: a driving controller configured to … drive a first third pixel, a second third pixel, a third third pixel and a fourth third pixel, among the plurality of third pixels of the third color based on … a selection signal that are generated to alternately have an enable level. (Bae, [0069], “According to various embodiments, the source driver 206 may include first to fourth sharing switches 311b, 312b, 313b, and 314b. The first sharing switch 311b may be disposed between the output terminal of the first amplifier 311 of the first pixel 161 and the output terminal of the first amplifier 321 of the third pixel 163. The second sharing switch 312b may be disposed between the output terminal of the second amplifier 312 of the first pixel 161 and the output terminal of the second amplifier 322 of the third pixel 163.

The fourth sharing switch 314b may be disposed between the output terminal of the fourth amplifier 314 of the second pixel 162 and the output terminal of the fourth amplifier 324 of the fourth pixel 164.”)
Bae however does not appear to disclose to sequentially drive a first third pixel, a second third pixel, a third third pixel and a fourth third pixel, among the plurality of third pixels of the third color.
Inokuchi however teaches a known technique to those of skill in the art to sequentially drive a first third pixel, a second third pixel, a third third pixel and a fourth third pixel, among the plurality of third pixels of the third color. (Inokuchi, [0033], [0034], “The gate driver 110 receives data from the timing controller 130, and sequentially selects and drives the multiple scanning lines LS.sub.1 through LS.sub.n.”)
It therefore would have been obvious to those having ordinary skill in the art before the effective filing date of the invention to sequentially drive the pixel as this was a known technique in view of Inokuchi and would have been utilized for the purpose of provides reduced power consumption of the liquid crystal display in addition it provides the source driver with reduced heat generation and high-speed operation. (Inokuchi, [0014-0018])
While both Bae and Inokuchi disclose a selection signal as being a single signal based switch, Bae and Inokuchi however do not expressly state that this is split into two signals and therefore does not appear to teach based on a first switch selection signal and a second switch selection signal that are generated to alternately have an enable level.
Mamba however teaches that it was a known technique to those having ordinary skill in the art to provide two separate alternative signals for driving the output switches and therefore teaches a first switch selection signal and a second switch selection signal that are generated to alternately have an enable level. (Mamba, See Fig. 7 items SA and SB. [0033], “Finally, the liquid crystal panel 102 is configured to include a display region 111 in the inside thereof. An image is displayed on the display region 111 by driving TFTs 108 using data lines 106 connected to the data driver circuit 100, a common line 109 and gate lines 107 connected to the gate driver circuit 101. Further, together with the display region 111, the liquid crystal panel 102 includes a switch array A which can change over polarities of the data lines 106 in response to a control signal SA outputted from the gate driver circuit 101, a switch array B which can change over polarities of the data lines 106 in response to a control signal SB outputted from the gate driver circuit 101, and a switch array Q which can change over polarities of the data lines 106 in response to a control signal EQ outputted from the gate driver circuit 101.”)
It therefore would have been obvious to those having ordinary skill in the art before the effective filing date of the invention to provide separate signal lines as this was a known technique in view of Mamba and would have been used for the art recognized purpose of providing the ability of changing over polarities of the data lines in response to a control signal. (Mamba, [0033]) In addition it is noted that it has been held that constructing a formerly integral structure in various elements involves only routine skill in the art. Nerwin v.

In addition, the source driver 206 may include a first switch 311a that is connected to an output terminal of the first amplifier 311 and a second switch 312a that is connected to an output terminal of the second amplifier 312.”)

Consider Claim 18:
Bae in view of Inokuchi discloses the display device of claim 17, further comprising: the driving controller is further configured to generate a first switch control signal to control the first output switch and the second output switch connected to a channel line having a same k value among the third channel lines, the fourth channel lines, the fifth channel lines, and the sixth channel lines. (Bae, [0070-0074], [0070], “According to various embodiments, the display driving circuit 200, when the output data of adjacent pixels are the same or within a specified threshold value (hereinafter, a shared threshold value), may drive other pixels together using the first to fourth sharing switches 311b, 312b, 313b, and 314b, by using source amplifiers corresponding to one pixel. For example, in FIG. 3A, the display driving circuit 200 may supply the output of the source amplifier supplied to the first pixel 161 and the second pixel 162 to the third pixel 163 and the fourth pixel 164 by using the first to fourth sharing switches 311b, 312b, 313b, and 314b.”)
Consider Claim 19:
Bae discloses a display device, comprising: (Bae, See Abstract.)
a pixel array comprising (Bae, [0006], “An electronic device according to various embodiments of the disclosure includes a processor, a display panel that includes a plurality of pixels (the plurality of pixels include a first pixel and a second pixel), and a display driving circuit that drives the display panel and receives image data to be displayed through the display panel from the processor, and the display driving circuit may be composed to identify output data of the first pixel and output data of the second pixel to display the image data, and, when the output data of the first pixel and the output data of the second pixel have more than a specified similarity, may be composed to drive the first pixel and the second pixel by using a source amplifier specified in relation to the first pixel.”)
a plurality of first pixels of a first color, a plurality of second pixels of a second color, and a plurality of third pixels of a third color, the plurality of first pixels of the first color and the plurality of third pixels of the third color repeatedly provided in odd-numbered pixel rows, and the plurality of second pixels of the second color and the plurality of third pixels of the third color repeatedly provided in even-numbered pixel rows; (Bae, [0063], “The display panel 160 of the pentile type may be, for example, in a form in which the gate lines and pentile source lines are alternately arranged. In FIG. 3A, although the display panel 160 is illustrated mainly including a case in which a first pixel 161, a second pixel 162, a third pixel 163, and a fourth pixel 164 are disposed adjacent to one another, the disclosure is not limited thereto (refer to FIG. 3B).”)
a plurality of first source amplifiers connected to each of a plurality of first source lines to drive the plurality of first pixels and the plurality of second pixels; and (Bae, [0065], “In the first pixel 161, the source driver 206 may include, for example, a first amplifier 311 supplying a signal to a first channel and a second amplifier 312 supplying a signal to a second channel among the pentile source lines. In addition, the source driver 206 may include a first switch 311a that is connected to an output terminal of the first amplifier 311 and a second switch 312a that is connected to an output terminal of the second amplifier 312.”)
a plurality of second source amplifiers connected to each of a plurality of second source lines to drive the plurality of third pixels, (Bae, [0067], “In the third pixel 163, the source driver 206 may include, for example, a first amplifier 321 supplying the signal to the first channel and a second amplifier 322 supplying the signal to the second channel among the pentile source lines. In addition, the source driver 206 may include a first switch 321a that is connected to an output terminal of the first amplifier 321 and a second switch 322a that is connected to an output terminal of the second amplifier 322.”)
wherein each of the plurality of first source lines and each of the plurality of second source lines are alternately provided, and two adjacent second source lines among the plurality of second source lines are connected to a corresponding second source amplifier among the plurality of second source amplifiers, wherein the display device further comprises: a driving controller configured to … drive a first third pixel, a second third pixel, a third third pixel and a fourth third pixel, among the plurality of third pixels of the third color. (Bae, [0070-0074], [0070], “According to various embodiments, the display driving circuit 200, when the output data of adjacent pixels are the same or within a specified threshold value (hereinafter, a shared threshold value), may drive other pixels together using the first to fourth sharing switches 311b, 312b, 313b, and 314b, by using source amplifiers corresponding to one pixel. For example, in FIG. 3A, the display driving circuit 200 may supply the output of the source amplifier supplied to the first pixel 161 and the second pixel 162 to the third pixel 163 and the fourth pixel 164 by using the first to fourth sharing switches 311b, 312b, 313b, and 314b.”)
Bae however does not appear to disclose to sequentially drive a first third pixel, a second third pixel, a third third pixel and a fourth third pixel, among the plurality of third pixels of the third color.
Inokuchi however teaches a known technique to those of skill in the art to sequentially drive a first third pixel, a second third pixel, a third third pixel and a fourth third pixel, among the plurality of third pixels of the third color. (Inokuchi, [0033], [0034], “The gate driver 110 receives data from the timing controller 130, and sequentially selects and drives the multiple scanning lines LS.sub.1 through LS.sub.n.”)
It therefore would have been obvious to those having ordinary skill in the art before the effective filing date of the invention to sequentially drive the pixel as this was a known technique in view of Inokuchi and would have been utilized for the purpose of provides reduced power consumption of the liquid crystal display in addition it provides the source driver with reduced heat generation and high-speed operation. (Inokuchi, [0014-0018])
While both Bae and Inokuchi disclose a selection signal as being a single signal based switch, Bae and Inokuchi however do not expressly state that this is split into two signals and therefore does not appear to teach based on a first switch selection signal and a second switch selection signal that are generated to alternately have an enable level.
Mamba however teaches that it was a known technique to those having ordinary skill in the art to provide two separate alternative signals for driving the output switches and therefore teaches a first switch selection signal and a second switch selection signal that are generated to alternately have an enable level. (Mamba, See Fig. 7 items SA and SB. [0033], “Finally, the liquid crystal panel 102 is configured to include a display region 111 in the inside thereof. An image is displayed on the display region 111 by driving TFTs 108 using data lines 106 connected to the data driver circuit 100, a common line 109 and gate lines 107 connected to the gate driver circuit 101. Further, together with the display region 111, the liquid crystal panel 102 includes a switch array A which can change over polarities of the data lines 106 in response to a control signal SA outputted from the gate driver circuit 101, a switch array B which can change over polarities of the data lines 106 in response to a control signal SB outputted from the gate driver circuit 101, and a switch array Q which can change over polarities of the data lines 106 in response to a control signal EQ outputted from the gate driver circuit 101.”)
It therefore would have been obvious to those having ordinary skill in the art before the effective filing date of the invention to provide separate signal lines as this was a known technique in view of Mamba and would have been used for the art recognized purpose of providing the ability of changing over polarities of the data lines in response to a control signal. (Mamba, [0033]) In addition it is noted that it has been held that constructing a formerly integral structure in various elements involves only routine skill in the art. Nerwin v. Erlichman, 168 USPQ 177, 179.
Consider Claim 20:
Bae in view of Inokuchi discloses the display device of claim 19, wherein two adjacent first source lines among the plurality of first source lines are connected to a corresponding first source amplifier among the plurality of first source amplifiers. (Bae, [0069], “According to various embodiments, the source driver 206 may include first to fourth sharing switches 311b, 312b, 313b, and 314b. The first sharing switch 311b may be disposed between the output terminal of the first amplifier 311 of the first pixel 161 and the output terminal of the first amplifier 321 of the third pixel 163. The second sharing switch 312b may be disposed between the output terminal of the second amplifier 312 of the first pixel 161 and the output terminal of the second amplifier 322 of the third pixel 163. The third sharing switch 313b may be disposed between the output terminal of the third amplifier 313 of the second pixel 162 and the output terminal of the third amplifier 323 of the fourth pixel 164. The fourth sharing switch 314b may be disposed between the output terminal of the fourth amplifier 314 of the second pixel 162 and the output terminal of the fourth amplifier 324 of the fourth pixel 164.”)
