Abstract

Provided is a liquid crystal display device, including: a plurality of data lines; and a plurality of source drivers configured to output a data signal to each of the plurality of data lines, in which the plurality of source drivers include a plurality of source drivers having different numbers of output channels for outputting the data signal, and in which the number of output channels of each of two first source drivers arranged at both end portions of the plurality of source drivers is set to be smaller than the number of output channels set for each of second source drivers adjacent to the two first source drivers.

First claim

What is claimed is:

1 . A display device, comprising:
a plurality of data lines; and a plurality of source drivers configured to output a data signal to each of the plurality of data lines, wherein the plurality of source drivers comprise a plurality of source drivers having different numbers of output channels for outputting the data signal, and wherein the number of output channels of each of two first source drivers arranged at both end portions of the plurality of source drivers is set to be smaller than the number of output channels set for each of second source drivers adjacent to the two first source drivers.

2 . The display device according to claim 1 , further comprising:
a display panel; and a backlight device configured to irradiate the display panel with light, wherein the backlight device comprises a light source arranged along at least one of a left side surface or a right side surface of the display panel, wherein the plurality of source drivers are arranged along at least one of an upper side surface or a lower side surface of the display panel, and wherein the two first source drivers are arranged at locations closer to the light source with respect to the second source drivers.

3 . The display device according to claim 1 ,
wherein each of the two first source drivers and the second source drivers comprises a shift register, and wherein the shift register is configured to perform shift operation in a direction from each of the second source drivers to corresponding one of the two first source drivers.

4 . The display device according to claim 1 ,
wherein each of the two first source drivers arranged at both the end portions comprises a shift register, and wherein a direction of shift operation of the shift register of one of the two first source drivers and a direction of shift operation of the shift register of another of the two first source drivers are opposite to each other.

5 . The display device according to claim 1 ,
wherein each of the plurality of source drivers comprises a shift register, wherein the plurality of source drivers are divided into a plurality of groups, wherein each of the plurality of groups comprises the first source driver and the second source driver, and wherein, in the each of the plurality of groups, the shift register is configured to perform shift operation in a direction from the second source driver to the first source driver.

6 . The display device according to claim 1 ,
wherein each of the plurality of source drivers comprises a shift register, wherein the plurality of source drivers are divided into a plurality of groups, and wherein, in each of the plurality of groups, the number of output channels set for corresponding one of the plurality of source drivers, which is arranged on an upstream side in a direction of shift operation of the shift register, is larger than the number of output channels set for corresponding one of the plurality of source drivers, which is arranged on a downstream side in the direction of the shift operation of the shift register.

7 . The display device according to claim 1 ,
wherein each of the plurality of source drivers comprises a shift register, wherein the plurality of source drivers are divided into a plurality of groups, and wherein, in each of the plurality of groups, the number of output channels set for corresponding one of the plurality of source drivers, which is arranged closer to a middle of a display panel, is larger than the number of output channels set for corresponding one of the plurality of source drivers, which is arranged farther from the middle of the display panel.

8 . A display device, comprising:
a plurality of data lines; and a plurality of source drivers configured to output a data signal to each of the plurality of data lines, wherein the plurality of source drivers comprise a plurality of source drivers having different numbers of output channels for outputting the data signal, and wherein the number of output channels of at least two source drivers arranged at both end portions of the plurality of source drivers is set to be smallest of a plurality of numbers of output channels set for the plurality of source drivers, respectively.
