Display driving method and device

Abstract

The invention relates to a display driving method and device, and the method comprises the steps: carrying out the partitioning of to-be-displayed current frame image data, and obtaining a plurality of pieces of image data; performing line segment mapping 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, wherein the line segment parameters comprise line segment pixel values and line segment lengths, each line segment corresponds to L columns of pixels, and L represents the line segment length; 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 frame image data by using the compensation data, and driving the display panel to display the updated current frame image data. Through adoption of the method and the device, the smear problem caused by long response time of 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 technology, 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, and are widely used in various industries, becoming 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 the screen to have motion smear or blur. For example, when using a mobile phone to move up and down the screen, it is easy to observe motion smear at the edges of the content such as strips, text, icons, and GUI, which affects the display effect. Such asfigure 1 As shown, assuming that the picture data bit width is 8bit (the value range is 0~255), the pixel value (Gray Lev...

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

like figure 1 As shown, assuming that the image data bit width is 8bit (value range 0-255), the pixel value (Gray Level, abbreviated as GL) is 64, and there is a gray band (GL192) scrolling vertically upward in the picture, and the band The edge moves from the line position Line A (line A) of the previous frame to the line position Line B (line B) of the current frame. If the panel response time is too long, motion smears will appear in the area between Line A and Line B phenomenon, the display panel will not be able to accurately display the image
