Method for implementing screen refresh and system thereof

Abstract

The invention discloses a screen refreshing realization method and a system thereof. The method comprises that: a corresponding refreshing time sequence configuration data initialization register group is selected according to the screen refreshing mode; the register group respectively stores operational orders and coordinate data which are corresponding to the refreshing time sequence and are used for transmitting the control time sequence of the operational order and the coordinate data and the reading and writing rules of the coordinate data. When refreshing the screen, the register group controls the transmission of the operational order and the coordinate data according to the control time sequence; the coordinate data which are transmitted are read according to the reading and writing rules of the coordinate data; and the screen refreshing is carried out according to the transmitted operational order and the read coordinate data. The screen refreshing realization method and the system of the invention are used for improving the generality of the operation of the screen refreshing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a screen refreshing method and system thereof. Background technique [0002] When the data in memory is displayed on the screen, the screen needs to be refreshed. For the screen of the parallel interface, when refreshing, it is necessary to send a control command to control the area displayed on the screen and the location of the written data. There are two ways to provide the control command: the program provided by the Driver IC (screen driver) manufacturer spells out the control command, or a dedicated display chip provides the control command. [0003] However, the program provided by the Driver IC manufacturer spells out the control command, and there are the following problems: [0004] Since there are many manufacturers of Driver ICs for DBI screens, and the methods of sending commands supported by the Driver ICs developed by each manufacturer are different, the re...

AI Technical Summary

Problems solved by technology

[0006] Since it is a dedicated display chip, it is generally aimed at a specific screen, and the set refresh timing is relatively fixed, so it cannot be used for the refresh process of other types of screens, resulting in poor versatility

[0007] In short, the current implementation of screen refresh is usually aimed at a specific screen and lacks versatility
