Abstract

The present application discloses a bilateral driving device and a tablet display. The bilateral driving device includes a first source driver, a second source driver and at least two driving signal lines connected to the first source driver, a second source driver, wherein the connection of the middle site of the at least two driving signal lines is not parallel to the specific edge of the display panel. By adapting the embodiment of the present application can utilize the visual characteristics of the human eye, the connection of the middle site of the at least two driving signal lines is not parallel to the edge of the display panel to confuse the dark spots and bright spots, to enhance brightness uniformity of the display panel, and improve the display quality.

First claim

wherein a connection of the middle site of the at least two driving signal lines is not parallel to a second specific edge of the display panel, and the connection of the middle site of adjacent two of the at least two driving signal lines is a straight line;
wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be in a triangular wave arrangement;
wherein along a specific direction of the second specific edge, a distance from the middle site of the at least two driving signal lines to the second specific edge is increasing or decreasing alternately within a predetermined distance range, and makes the middle site of the at least two driving signal lines can be in a triangular wave arrangement; and
wherein along the specific direction of the second specific edge, the distance from the middle site of the at least two driving signal lines to the second specific edge can be a first distance and a second distance alternately, and makes the distance from the middle site of the at least two driving signal lines to the second specific edge is increasing or decreasing alternately within a predetermined distance range.

2. The bilateral driving device according to claim 1 , wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be in a trapezoidal wave arrangement.

3. The bilateral driving device according to claim 1 , wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be in stepped increasing arrangement or in stepped descending arrangement alternately.

4. The bilateral driving device according to claim 1 , wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be serrated increasing or decreasing in alternatively.

5. The bilateral driving device according to claim 1 , wherein the first source driver and the second source driver are distributed and arranged along two opposite edges of the display panel separately, and wherein the second specific edge is the edge of the first source driver distributed along or the edge of the second source driver distributed along.

6. A tablet display, wherein the tablet display comprising a display panel and a bilateral driving device, wherein the bilateral driving device is used to provide a source driving signal to the display panel;
the bilateral driving device comprising a first source driver, a second source driver and at least two driving signal lines connected to the first source driver, a second source driver, wherein each of the at least two driving signal lines comprises a middle site at middle of the driving signal line, and each of the at least two driving signal lines is parallel to a first specific edge of the display panel;
wherein a connection of the middle site of the at least two driving signal lines is not parallel to a second specific edge of the display panel, and the connection of the middle site of adjacent two of the at least two driving signal lines is a straight line;
wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be in a triangular wave arrangement;
wherein along a specific direction of the second specific edge, a distance from the middle site of the at least two driving signal lines to the second specific edge is increasing or decreasing alternately within a predetermined distance range, and makes the middle site of the at least two driving signal lines can be in a triangular wave arrangement; and
wherein along the specific direction of the second specific edge, the distance from the middle site of the at least two driving signal lines to the second specific edge can be a first distance and a second distance alternately, and makes the distance from the middle site of the at least two driving signal lines to the second specific edge is increasing or decreasing alternately within a predetermined distance range.

7. The tablet display according to claim 6 , wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be in a trapezoidal wave arrangement.

8. The tablet display according to claim 6 , wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be in stepped increasing arrangement or in stepped descending arrangement alternately.

9. The tablet display according to claim 6 , wherein with respect to the second specific edge, the connection of the middle site of the at least two driving signal lines can be serrated increasing or decreasing in alternatively.

10. The tablet display according to claim 6 , wherein the first source driver and the second source driver are distributed and arranged along two opposite edges of the display panel separately, and wherein the second specific edge is the edge of the first source driver distributed along or the edge of the second source driver distributed along.
