Abstract

The invention provides a refreshing method and system of a display screen and a display screen controller. The refreshing method of the display screen comprises the steps that a central processing unit sends real-time data to the display screen controller; the display screen controller receives the real-time data; the display screen controller stores the real-time data; the display screen controller compares the real-time data with prestored data to generate a comparison result; the display screen controller judges whether updating happens according to the comparison result; when updating happens, the display screen controller calculates the minimum refreshing area; the display screen controller refreshes the minimum refreshing area of the display screen. According to the refreshing method and system of the display screen and the display screen controller, the minimum refreshing area corresponding to updating content only needs to be refreshed, so that the efficiency is improved, and electricity is also saved.

Description

technical field [0001] The invention relates to the display field, in particular to a display screen refreshing method, system and display screen controller. Background technique [0002] Usually, a complete display system includes three parts, namely, a host, a display controller and a display. The host sends data, and the display controller processes the data and sends it to the display for display. Since the data sent by the host may be updated, the display controller needs to refresh the display. [0003] Currently, the display screen controller refreshes the display screen in a way that the display screen controller continuously refreshes the full screen content of the display screen, which is inefficient and does not save power. Contents of the invention [0004] In view of the above, the present invention proposes a display screen refreshing method, system and display screen controller. [0005] One aspect of the present invention proposes a method for refreshing ...
