Automatic configuration method of touch display screen, display control module and display system

Abstract

An automatic configuration method of a touch display screen, a display control module and a display system are disclosed. In the display control module, a screen-to-screen identifier mapping table, a configuration table of each screen and a current screen identifier are pre-stored, and the configuration table comprises a plurality of screen parameters and corresponding configuration information thereof.The method includes the following steps: 1) when a display control module is initialized, automatically reading a screen identifier of the connected touch display screen through an I2C interface; 2) comparing the obtained screen identifier with the current screen identifier; and if the screen identifier is not matched with the current screen identifier, calling the configuration information corresponding to the screen identifier, and entering step 3), and if the screen identifier is matched with the current screen identifier, continuing to use the current screen parameter and the corresponding configuration information; and 3) corresponding screen configuration information is found according to the screen identifier mapping table to update the driving information, so that the display control module can correctly display, and a new screen identifier is updated to the current screen identifier storage area. Automatic screen matching is achieved, human intervention is reduced, the error probability is lowered, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of display systems, in particular to an automatic configuration method for a touch screen, a display control module and a display system. Background technique [0002] As a visual electronic display system, the touch display is the most important component. However, due to screen replacement or market changes in screen resources, a display system will frequently replace resources, that is, repeatedly upgrade screen hardware or replace screens from different manufacturers; however, electronic products themselves have different sizes, such as 43, 55, 65, 70, 75, 86, 98 and other sizes. Due to the superimposition of the three factors of screen upgrade x different manufacturers x different sizes, even if other parameters of the display system remain unchanged, dozens of variants can be extended by only configuring the screen alone, which makes the system software maintenance very heavy. [0003] For example, one system ...
