Problems solved by technology

[0005] However, in the prior art, the update of the picture on the EPD display screen adopts global (full screen) refresh. If the size of the screen is 600×800, the data transmitted each time must be 600×800 pixel data. After sending the display command, the EPD control The device will display 600 × 800 pixel values; that is, when updating the picture on the display screen, when only part of the picture changes on the display screen, the whole pic

Abstract

A display device, a method and device for refreshing a display interface, wherein the method for refreshing a display interface includes: acquiring pixel data of a current display interface and a next display interface; comparing the pixel data of the current display interface and the next display interface, Determine the changed pixels of the next display interface relative to the current display interface; based on the pixel data of the corresponding changed pixels in the next display interface, refresh the display area of ​​the display interface corresponding to the changed pixels. The display device, the method and device for refreshing the display interface of the present invention use local refresh to refresh the display area corresponding to the changed pixels, so as to avoid the screen flicker phenomenon that occurs when the display device in the prior art adopts global (full screen) refresh.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a display interface refreshing method thereof, a display interface refreshing method and a device. Background technique [0002] With the advent of the information age, due to the increasing demand of people to communicate with the outside world, the display device with the function of disseminating information has become one of the indispensable electronic products for modern people. The display device has developed from the original cathode ray tube (CRT) display to the thinner and thinner liquid crystal display (LCD), which has been widely used in communication, information and consumer electronics products. However, since the liquid crystal display needs to continuously provide power for operation, thus wasting electric energy, a more power-saving electrophoretic display (Electrophoretic display) display technology has been developed. [0003] Use compu...
