Working Principles

The PCM1602KY/2KG4 LCD module utilizes the principles of liquid crystal technology. It consists of a matrix of tiny liquid crystal cells that can be controlled individually to form characters or graphics. When an electric field is applied, the liquid crystals align to allow or block the passage of light, resulting in the formation of characters on the display.
