Display device, and refreshing method and device of display interface

Abstract

The invention provides a display device, a refreshing method and a refreshing device of a display interface. The refreshing method of the display interface comprises the following steps of: acquiring a control, changing relative to the current display interface, of a next display interface; acquiring pixel data of a display region corresponding to the changed control; and refreshing the display interface based on the pixel data and coordinate data of the display region corresponding to the changed control. In the display device, the refreshing method and the refreshing device of the display interface, the display region corresponding to the changed control is locally refreshed; and the screen flash phenomenon of the display device caused by overall (full screen) refreshing in the prior art is avoided.

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 initial 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, a more power-saving electrophoretic display (Electrophoretic display) display technology has been developed. [0003] Use computers to process and save a larg...

[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 picture will still be updated again, due to the slow refresh rate of the EPD in the prior art ( The refresh rate is about 700ms), and there will be a flickering phenomenon when global refresh is used

[0006] There are many patents on electronic paper displays and their driving methods in the prior art, such as the Chinese patent application with application number 200880000725.3, but none of them solves the above-mentioned shortcomings of the prior art
