Problems solved by technology

[0004] In order to be able to compare the picture changes of the two frames before and after in functions such as overvoltage driving, it is necessary to store the current picture. The principle is generally to input the current frame picture into the data compression module, compress the data and then send it to the memory. However, the setting of the data compression ratio is very important in practical applications. If the data compression ratio is set too small, it will cause too much data to be stored, which will increase the cost. If the data compression ratio is set too high, It will lead to an increase in the error in the process of compression and decompression, which will affect the display effect of the picture. How to achieve a balance point according to the actual picture performance is a problem that is difficult to solve well

Abstract

The invention discloses a picture storage method and a display panel. The picture storage method comprises the following steps: inputting a current-frame picture into a gray scale judging module; judging a gray scale value of the current-frame picture, and outputting the current-frame picture to a corresponding data compression module; compressing the current-frame picture according to a corresponding data compression rate parameter by the data compression module; and transmitting the compressed current-frame picture to a storage to store the compressed current-frame picture. According to thepicture storage method disclosed by the invention, current-frame pictures corresponding to different gray scales are compressed by different data compression rate parameters, so that the cost and thepicture quality can be taken into consideration better.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a picture storage method and a display panel. Background technique [0002] With the development and progress of science and technology, liquid crystal display has become the mainstream product of display due to its thin body, power saving and low radiation, and has become an important display platform for IT and video products. [0003] From the perspective of the driving principle of the LCD, the system motherboard passes the red / green / blue compressed signal and the power supply of the control signal machine through the wire, and finally connects it to the display area of ​​the display panel, so that the display panel can obtain the required power and signal. [0004] In order to be able to compare the picture changes of the two frames before and after in functions such as overvoltage driving, it is necessary to store the current picture. The principle is generally to input th...
