Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] The devices on which the present invention is based such as figure 1 As shown, it includes a host computer, a graphic generator and a MIPI liquid crystal module connected in sequence, wherein the graphic generator includes an ARM (Advanced RISC Machines) core module and a single-chip microcomputer.

[0021] The implementation of the present invention is that the upper computer is connected to the graphic generator through the network, the user edits the MIPI initialization code file according to a specific format through the upper computer initialization code editing interface, and the upper computer program parses the MIPI initialization code file customized by the user into the bottom layer Recognizable hexadecimal initialization code file, before the MIPI LCD module is powered on, the ARM core module reads the corresponding hexadecimal...

Abstract

The invention relates to an initial configuration method of a mobile industry processor interface (MIPI) liquid crystal module. The method comprises the steps of compiling an MIPI initialization code file according to a specific format by an initialization code editor interface of an upper computer; parsing the MIPI initialization code file which is edited in a user defined way into an identifiable hexadecimal initialization code file by the program of the upper computer; before the MIPI liquid crystal module is electrified, using an ARM kernel module to read the corresponding hexadecimal initialization code file, and sending the read result into a singlechip to realize the initialization function before the MIPI liquid crystal module is lightened. The method can meet the demand of carrying out flexible compatibility on initialization codes of various types of MIPI liquid crystal modules, thus reducing the version number and the upgrading times of the program of the singlechip.

Description

technical field [0001] The invention relates to the technical field of liquid crystal module detection, in particular to a MIPI (Mobile Industry Processor Interface, mobile communication industry processor interface) liquid crystal module initialization configuration method. Background technique [0002] At present, before the MIPI LCD module lights up, it is necessary to send a series of parameters to the LCD module through the register. The content of the parameters may include Power setting information, Vcom (Common Voltage, common terminal voltage) Group ID, gamma parameters and other settings are implemented in the form of a graphics generator microcontroller writing a series of values ​​​​to the registers of the MIPI LCD module, which is the initialization code. The initialization codes corresponding to different types of MIPI LCD modules are different, so specific settings are required. The initialization code corresponds to it. Currently, the processing of the initia...
