Driver IC & PCBA
The driver IC & PCBA is a basic component of LCD's. The main function of Driver ICs is to output the needed voltage of the pixels and control the rotate level of liquid crystal.
There are two types of Driver ICs, the Source Driver IC and the Gate Driver IC.
The Source Driver IC manages the information input and has high-frequency and imaging functions.
The Gate Driver IC determines the rotation and speed of liquid crystal.
