Problems solved by technology
[0003] However, with the increase of the refresh rate, there will be a problem of display crosstalk, which will affect the picture quality of the display product, and then affect the viewing experience of the user. Therefore, how to reduce the crosstalk problem caused by the high refresh rate is very important.

Embodiment Construction
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art based on the present application belong to the protection scope of the present invention.
[0049] Display screen crosstalk (also called: Crosstalk, CT for short) refers to the distortion of the picture caused by a piece of other color picture on the solid color background picture, which causes the brightness of the adjacent area to change. The phenomenon of crosstalk is divided into horizontal crosstalk and vertical crosstalk. In an example, such as figure 1 As shown, in a solid-color picture with a grayscale value of L127, when a black image is di...

The embodiment of the invention provides a sub-pixel opening sequence determination method, a sub-pixel opening method and a pixel driving circuit. The sub-pixel opening sequence determination method comprises the steps of for sub-pixels in a specified pixel row of a display panel to be tested, obtaining a vector coupling voltage generated by other sub-pixels in the same row in the next charging time due to the charging voltage of the sub-pixel in the current charging time; obtaining an opening sequence of each preset sub-pixel; for each preset sub-pixel opening sequence, calculating a horizontal crosstalk value of pixels in the specified pixel row under the preset sub-pixel opening sequence according to the opening sequence of each sub-pixel in the preset sub-pixel opening sequence and the vector coupling voltage; and selecting a target sub-pixel opening sequence according to the horizontal crosstalk value of the pixels under each preset sub-pixel opening sequence. The influence degree of the horizontal crosstalk can be evaluated through the calculated horizontal crosstalk value, and the horizontal crosstalk caused by a high refresh rate can be effectively improved by selecting the starting sequence of the target sub-pixels.
Description
technical field [0001] The present invention relates to the technical field of high-frequency display horizontal crosstalk, and in particular to the determination of sub-pixel turn-on sequence, a sub-pixel turn-on method, and a pixel drive circuit. Background technique [0002] High-frequency display refers to high-refresh-rate screen display. High-refresh-rate screen refers to a display product with a picture refresh rate higher than 60HZ within 1 second. This display product was first applied in the field of e-sports, which can optimize the user’s competitive experience and greatly Improve the visual experience of customers and experience the impact of smooth video. In recent years, high refresh rate screens have become an important choice for mobile phone panels. The refresh rate ranges from 90HZ to 120HZ and 140HZ, and has been sought after by mobile game enthusiasts. Mobile phone panels with high refresh rate screens have now been extended to mid-range mobile phones. ...
