Embodiment Construction

[0022] Embodiments of the electronic equipment of the present invention will be described below with reference to the accompanying drawings.

[0023] The method for manufacturing electronic equipment with an LCD display includes the following steps:

[0024] Step A: Pre-set a plurality of identification pins 2004 for each compatible display screen, each of which outputs a level when the electronic device is turned on, and all the identification pins of each display screen The value combination of the level corresponds to a display model;

[0025] Set a corresponding driver function for each compatible display, and define a dynamic function pointer pointing to the driver function for each driver function;

[0026] Compile a unified software package, integrate the above-mentioned display model and the value of the output level of the identification pin 2004, the corresponding relationship between the dynamic function pointer and the display model, and the relevant content of th...

Abstract

The invention discloses an electronic device, a manufacturing method thereof and a method for identifying and driving a display screen. The manufacturing method comprises the following steps: presetting identification pins for each compatible display screen, wherein the combination of the level values of all the identification pins of each display screen is corresponding to the size of the display screen and a driving function; defining a dynamic function indicator for indicating the driving function for each driving function; compiling a uniform software package; integrating the related contents in the software package and unloading to a mobile phone; and at the moment of starting the mobile phone, identifying the size of display screen by reading the combination of the level values of the identification pins, thereby acquiring the corresponding dynamic function indicator and retrieving and performing the driving function through the dynamic function indicator and finally driving the display screen to display. According to the method, the operation of compiling different software aiming at a driving chip is unnecessary and repeated downloading is unnecessary, so the method has the advantage of increasing the efficiencies of development, production and after-sale service of the electronic device.

Description

technical field [0001] The invention relates to an electronic device and a manufacturing method thereof, in particular to an electronic device and a manufacturing method thereof, and a method for identifying and driving a display screen. Background technique [0002] At present, in the design of mobile phones, it is often necessary for multiple manufacturers to make molds and test for LCD modules. Since the LCD module is a special part and there are many types, it needs to be equipped with special driver software and driver chips. Each LCD module corresponds to a dedicated driver software. In addition, most LCD modules currently do not set a dedicated ID. Therefore, it is impossible to read out the ID number through the "read" signal to identify a wide variety of LCD modules. [0003] In the process of mobile phone research and development, it is often encountered that different types of LCD modules need to be compatible, and the driver chips used by these LCD displays may ...
