Abstract

A display system and a driving method for a display panel. The display system includes a display panel, a display area dividing device and a display driving device. A display panel includes a display area; a display area dividing device is configured to divide the display area of the display panel into at least a first display area and a second display area; a display driving device is configured to drive the first display area with a first refresh frequency and drive the second display area with a second refresh frequency, and the first refresh frequency is greater than the second refresh frequency.

First claim

What is claimed is:

1. A display system, comprising:
a display panel comprising a display area;
a display area dividing device configured to divide the display area of the display panel into at least a first display area and a second display area;
a display driving device configured to drive the first display area with a first refresh frequency and drive the second display area with a second refresh frequency; and
a first group of gate lines, a first group of data lines, a second group of gate lines, a second group of data lines,
wherein the first refresh frequency is greater than the second refresh frequency;
the first display area and the second display area are two display areas with fixed positions in the display panel;
the second display area encircles the first display area;
the display driving device comprises a first display driving device and a second display driving device;
the first display area connects the first display driving device via the first group of gate lines and the first group of data lines, and the second display area connects the second display driving device via the second group of gate lines and the second group of data lines;
the first group of gate lines and the second group of gate lines do not share a common gate line, and the first group of data lines and the second group of data lines do not share a common data line; and
the first display driving device is configured to drive the first display area with the first refresh frequency, and the second display driving device is configured to drive the second display area with the second refresh frequency.

2. The display system according to claim 1 , wherein
the display area dividing device is further configured to divide the display panel into the first display area, the second display area and a third display area, and wherein the third display area is located between the first display area and the second display area.

3. The display system according to claim 2 , wherein
the display driving device is further configured to drive the third display area with a third refresh frequency that is less than the first refresh frequency and greater than the second refresh frequency.

4. The display system according to claim 1 , wherein
the display driving device is configured to increase a frame rate of a video image displayed by the first display area to the first refresh frequency by inserting frame.

5. The display system according to claim 4 , wherein
the display driving device comprises a graphics processing unit; and
the graphics processing unit is configured to obtain at least one frame of intermediate image based on two adjacent frames of images of the video image and to increase the frame rate of the video image displayed by the first display area to the first refresh frequency by inserting the at least one frame of intermediate image between the two adjacent frames of images.

6. The display system according to claim 1 , wherein the display area dividing device is configured to divide the display area of the display panel into at least the first display area and the second display area according to a working distance of the display panel and view angle characteristics of distinguish ability of human eyes.

7. A driving method for a display panel, comprising:
dividing a display area of the display panel into at least a first display area and a second display area; and
driving, by a first display driving device, the first display area with a first refresh frequency, and driving, by a second display driving device, the second display area with a second refresh frequency,
wherein the first refresh frequency is greater than the second refresh frequency;
the first display area and the second display area are two display areas with fixed positions in the display panel;
the second display area encircles the first display area;
the first display area connects the first display driving device via a first group of gate lines and a first group of data lines, and the second display area connects the second display driving device via a second group of gate lines and a second group of data lines; and
the first group of gate lines and the second group of gate lines do not share a common gate line, and the first group of data lines and the second group of data lines do not share a common data line.

8. The method according to claim 7 , wherein
the display panel is divided into the first display area, the second display area and a third display area, and the third display area is located between the first display area and the second display area.

9. The method according to claim 8 , further comprising:
driving the third display area with a third refresh frequency, wherein
the third refresh frequency is less than the first refresh frequency and greater than the second refresh frequency.

10. The method according to claim 7 , further comprising:
increasing a frame rate of a video image displayed by the first display area to the first refresh frequency by inserting frames.
