Display driving method and device

Abstract

The invention relates to a display driving method and device, and the method comprises the steps: partitioning current frame image data in a row unit to acquire a plurality of pieces of block image data; mapping line segments on pixels in each piece of image data, and determining line segments corresponding to the pixels of each piece of image data and line segment parameters of the line segments;acquiring line segment parameters of corresponding block image data in the previous frame image data, and determining compensation data by utilizing the current frame image data, the line segment parameters of each block image data of the current frame image data and the line segment parameters of the corresponding block image data in the previous frame image data; and updating the current frameimage data by using the compensation data, and driving the display panel to display the updated current frame image data. Through the method and the device, trailing smear caused by long response timeof the panel can be eliminated, and the display accuracy of the display panel is improved.

Description

technical field [0001] The present disclosure relates to the field of display technologies, and in particular, to a display driving method and device. Background technique [0002] At present, flat-panel displays such as LCD, LED and OLED have gradually replaced traditional displays such as CRT, are widely used in various industries, and become an indispensable component of most electronic devices (such as mobile phones, Pads, TVs, computers, etc.). The response time of the panel is an important factor to measure the characteristics and quality of various types of panels. When the response time is too long, it will cause motion smear or blur in the picture. For example, when using a mobile phone to slide up and down the screen, it is easy to observe motion smears at the edges of strips, text, icons, GUI and other content, which affects the display effect. Such as figure 1 As shown, assuming that the image data bit width is 8bit (value range 0-255), the pixel value (Gray Le...

Problems solved by technology

The response time of the panel is an important factor to measure the characteristics and quality of various types of panels. When the response time is too long, it will cause motion smear or blur on the screen.

For example, when using a mobile phone to scroll up and down the screen, it is easy to observe motion smears at the edges of strips, text, icons, GUI and other content, which affects the display effect

As shown in Figure 1, it is assumed that the image data bit width is In the application of 8bit (value range 0~255), the pixel value (Gray Level, abbreviated as GL) is 64, and there is a gray strip (GL192) scrolling vertically upward in the screen, and the edge of the strip is from the line position Line A of the previous frame (Line A) moves to the line position Line B (Line B) of the current frame. If the panel response time is too long, there will be motion smear phenomenon in the area between Line A and Line B, and the display panel will not be able to accurately display the image.
