Description

technical field

[0001] The invention relates to the field of embedded mobile terminals, in particular to a method, device and terminal for identifying liquid crystal display screens. Background technique

[0002] With the continuous development of science and technology, more and more embedded products are used in our daily life. They are popular for their small size and convenient use, and LCD screens are indispensable in many embedded products. It is part of people's most intuitive impression of this terminal product. The working principle of the LCD screen is that when the terminal system is turned on, the microprocessor first writes the working parameters corresponding to the internal driver chip of the LCD screen into the driver chip, and completes the initialization of the driver chip, so as to ensure that the LCD screen normal work.

[0003] However, as the demand for terminal products continues to increase, the market for liquid crystal display screens is also incr...
