Working Principle

GLK240128-25-422 display module works by using a host interface controller to control the electronic circuitry of the module. The controller acts as an interface between the display and the computer, allowing the display to be connected to the computer for data transfer. The controller then controls the display list, which consists of commands that enable the LCD to render the graphical data on screen. The controller also controls the LCD gate driver and LCD source driver, which enable the display to refresh and refresh each pixel.

Finally, the display is powered by a 4-bit RGB interface, which includes two or four integrated voltage regulation (IVR) power supplies. The IVR supplies are used to supply power to the display and to control the contrast and brightness of the display. This allows users to adjust the display to their preferences, while still maintaining the entire system’s power efficiency.
