Display driving method, circuit and display device

Abstract

The present application discloses a display driving method, circuit and display device. The method includes: when the image to be displayed is the target image, converting the first level value of the first clock signal to a second level value, and the second level value is less than the first level value; send the first clock signal; judge whether the second level value belongs to the first high level threshold; if so, determine that the third level value is the level value of the first clock signal, and send the level The first clock signal after the value update can solve the display quality problem of horizontal or vertical bright stripes on the display screen.

Description

technical field [0001] The present invention generally relates to the field of display driving, and in particular to a display driving method, circuit and display device. Background technique [0002] The display driving technology of the display screen can be realized by using the scan signal provided by the gate drive line and the pixel signal provided by the source drive line. In order to save power consumption, the connection points between the source driving lines and the red, green and blue sub-pixels in the display screen pixels are arranged in a Z shape. During the display driving process of the display screen, the scanning signals provided by the gate driving lines will correspond to When the sub-pixel is turned on, at this time, the pixel data provided by the source driving line is converted into the corresponding pixel level, and the corresponding gray scale is displayed to realize the picture display of the display screen. [0003] However, when the connection p...

Problems solved by technology

[0003] However, when the connection points between the source drive lines and the red, green and blue sub-pixels are arranged in a Z shape, when a high-gray-scale two-color picture is displayed, the pixel level value of the sub-pixels will appear periodic high voltage phenomenon. , the two-color screen means that the color displayed on the screen is composed of two sub-pixels, and horizontal or vertical bright stripes will periodically appear on the display screen

[0004] In related technologies, when a two-color picture (such as a cyan or orange picture) is displayed, the overdrive (English: over driver, abbreviated: OD) technology can be used to increase the pixel level value of the sub-pixel with a lower pixel voltage, so that the pixel voltage The flat value is the same as the pixel level value of the sub-pixel with high pixel level value to solve this display quality problem, but this technology not only has a high amount of computation, but also is difficult to debug and the processing effect is not ideal.
