Problems solved by technology

[0005] However, the refresh rate of the display screen in the prior art is usually fixed and non-adjustable, and the refresh rate of 60HZ cannot meet the needs of dynamic display. Although a high refresh rate can improve the display effect of moving object images, it is not suitable for static, or The image of objects with low moving speed will cause the logic power consumption of the display screen to be too high, which is not in line with the concept of low-carbon environmental protection

Abstract

The invention provides a display screen dynamic frame frequency drive circuit and a drive method. The dynamic frame frequency driving circuit of the display screen includes: an interface module (1), a power supply module (2), a timing control module (3), a frame frequency determination module (4), a gamma voltage module (5), and a source driving module (6). The frame rate determination module (4) can determine the motion speed of objects in two consecutive frames of pictures, and provide a high-frequency frame rate signal or a low-frequency frame rate signal to the source driver module (6) according to the motion speed of the object, so that in When the motion speed of the object in two consecutive frames is fast, the refresh frequency of the source driver module (6) is high, and when the motion speed of the object is slow in two consecutive frames, the refresh frequency of the source driver module (6) is low, In this way, it can not only make the display of the dynamic picture smooth, but also reduce the logic power consumption of the display screen, and realize the green product concept of low carbon and environmental protection.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen dynamic frame rate drive circuit and a drive method. Background technique [0002] At present, liquid crystal displays (Liquid Crystal Display, LCD) and other flat panel display devices are widely used in mobile phones, televisions, personal digital assistants, and digital cameras due to their advantages of high image quality, power saving, thin body, and wide application range. , Notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. Display screens in flat panel display devices have become a major human-computer interaction tool. [0003] Taking the display screen of a liquid crystal display as an example, each pixel in the display screen is electrically connected to a thin film transistor (TFT), the gate (Gate) of the thin film transistor (Gate) is connected to the scanning line, and the s...
