Technical details and manufacturing context for Driver PCB

Definition
A specialized printed circuit board that serves as the electronic interface between the main controller and the LCD panel. It receives digital signals, processes timing and voltage requirements, and delivers precise electrical signals to activate individual pixels on the display.
Working Principle
The Driver PCB receives video data and control signals from the main controller via interfaces like LVDS, eDP, or MIPI. It processes these signals through timing controllers (T-CON) and driver ICs, converting them into precise voltage levels and timing sequences required to charge and maintain the liquid crystal cells in the LCD panel, controlling light transmission through each pixel.
