1. Overview of LCD LCD Module Driver: Debugging the LCD module driver program is a very important part of the entire mobile phone development process. In the early stages of each new model development, the first step is to debug the LCD module driver program, commonly known as "touch screen". The debugging of "dot screen" includes two parts: one is to turn on the backlight of the LCD, and the other is to debug the LCD display. The methods and techniques for debugging backlight drivers will be described in the backlight documentation.
2. The principle and concept of LCD liquid crystal module: LCD: The full name is Liquid Crystal Display Liquid Crystal Display LCD: The full name is Liquid Crystal Module, which refers to the liquid crystal display module, including the liquid crystal screen and its peripheral FPC circuits and structural components.
3. FPC circuit of LCD: Refers to the peripheral circuit of LCD in the LCM module, which is designed by the LCD module manufacturer according to our interface requirements for LCD. Looking at the FPC circuit diagram is also an important step in LCD driver debugging.
4. LCD peripheral circuit: We usually refer to it as the LCD circuit, which refers to the LCD interface circuit on the baseband end. This part of the circuit is designed by us.
