Problems solved by technology

Therefore, the improvement effect of the color shift phenomenon needs to be improved
[0004] In addition, due to the influence of its own characteristics, the thin film transistors in each pixel circuit of the display in the related art need a certain time to be turned on and off.
This will cause the problem of grayscale inversion of the PWM driving method, resulting in a decrease in the visual experience of the human eye and affecting the viewing effect

Abstract

The invention relates to a hybrid driving method of a display and a hybrid driving module of the display. The method comprises the following steps: acquiring a to-be-displayed gray scale input to the display; adjusting the light-emitting duration of at least one first subframe and / or the light-emitting duration of at least one second subframe according to the gray scale to be displayed; and driving a display to display according to the adjusted light emitting duration of each first sub-frame and / or the adjusted light emitting duration of each second sub-frame. Hybrid driving is adopted, the to-be-displayed gray scale input to the display is obtained, then the light-emitting duration of at least one first sub-frame and / or the light-emitting duration of at least one second sub-frame is adjusted according to the to-be-displayed gray scale, and finally display is driven according to the adjusted light-emitting duration of each first sub-frame and / or the adjusted light-emitting duration of each second sub-frame. The brightness uniformity of different gray scales can be improved, the color cast phenomenon and the gray scale overturning phenomenon are further improved, meanwhile, the uniformity of a display picture is improved, the pocking mark phenomenon is eliminated, and the display effect of hybrid driving is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a hybrid driving method for a display and a hybrid driving module for a display. Background technique [0002] In the current display field, the continuous development and progress of display technologies such as LED displays and AMOLED displays bring more and more display products. At present, a PAM (Pulse Amplitude Modulation, ie, pulse amplitude modulation) driving mode is often used to drive a display for display. However, when the PAM driving method is used alone, although the display brightness is not lost, the color shift phenomenon will appear when displaying low grayscale images. [0003] In the related art, there have been solutions to improve the low gray-scale color cast and minimize the loss of brightness by means of PWM and PAM hybrid driving. After adopting PWM (Pulse Width Modulation, that is, pulse width modulation) driving, although the phenome...
