(1) LCD (liquid crystal display) commonly known as liquid crystal display

(2) Liquid crystal is a material. Liquid crystal has a feature: it can rotate the liquid crystal molecules under the drive of electrical signals, thus affecting the light transmittance. Therefore, we can use the white light behind the entire LCD panel (called the backlight) to selectively transmit light through different electrical signals. At this time, you can see various colors in front of the LCD panel, which is LCD Display.

(3) Passive lighting and active lighting. Some displays, such as LED displays and CRT displays, emit light on their own, called active lighting. Some (LCD Module) do not emit light by themselves, but only transmit light. It needs the help of a backlight to appear glowing, which is called passive lighting.
