Speaking of TN, STN, VA, you may feel strange. In fact, they all belong to the liquid crystal display technology, and we have long been exposed to them in our daily lives through cell phones, computers, TVs and other electronic devices. The difference of them lies in the arrangement of liquid crystals, twisting angle and circuits. TN (Twisted Nematic) display is one of the earliest LCD. Liquid crystals are placed between two conductive glass substrates. When not energized, incident light passes through the liquid crystal layer after passing through the polarizer, and the polarized light is rotated 90° by the liquid crystal layer with twisted arranged molecules. When energized, the direction of polarization of light will no longer change, and the beam of light can not pass through the second piece of polarizer, so that the screen will be dark. TN display is cheap, with fast response speed (up to 1ms or so) and can support a very high refr...

LCD interface is an important connection between the controller and LCM, and the controller can transmit the required information to the LCD to display through the interface.
