Problems solved by technology

In the prior art, the initialization code of the liquid crystal display module is stored in the flash memory (Flash Memory) of the mobile phone. Because the flash storage capacity of the mobile phone is small, a large amount of said initialization codes cannot be stored, so when using different liquid crystal display modules, it is necessary to The initialization code in the flash memory is updated, so the plug-and-play of the liquid crystal display module in the mobile phone cannot be realized

Abstract

The present invention discloses a plug and play method for a liquid crystal display module of a mobile phone, and the liquid crystal display module. The method comprises: the data of the drive program of the liquid crystal display module is stored in a read only memory of the liquid crystal display module, the liquid crystal display module is connected with a microprocessor controller of the mobile phone, initialization data in the read only memory is read by the microprocessor controller of the mobile phone, and an initialization code is written in a drive chip of the liquid crystal display module by the microprocessor controller of the mobile phone. The liquid crystal display module comprises the read only memory and a drive program interface which is used for reading the data of the drive program. By using the method and the liquid crystal display module, the plug and play between the hardware system of the mobile phone and the liquid crystal display module provided by different manufacturers can be realized. Therefore, the compatibility problem of the liquid crystal display module of the mobile phone is solved, and the cost and the period of research and development of the mobile phone are reduced.

Description

technical field [0001] The invention relates to a method for realizing plug and play of a mobile phone liquid crystal display module and a liquid crystal display module. Background technique [0002] A liquid crystal display module (LCM, liquid crystal modul) is a component that assembles a liquid crystal display (LCD, Liquid Crystal Display), a driver chip, a PCB circuit board, a backlight source, and connectors. Due to the difference between the LCD screen and the driver chip, different LCM drivers are required for control. Since different types of LCD modules provided by various module manufacturers are different, different initialization codes are required. In the prior art, the initialization code of the liquid crystal display module is stored in the flash memory (Flash Memory) of the mobile phone. Because the flash storage capacity of the mobile phone is small, a large amount of said initialization codes cannot be stored, so when using different liquid crystal display...
