A touchscreen (aka digitizer) is a thin layer of clear plastic that reads the signal from the touch and transmits it to the processing unit. It’s the part you can touch without disassembling the device. The LCD screen is the panel inside the device that displays images.

The LCD display uses liquid crystal display technology. The screen is embedded with liquid crystals, a substance that is somewhere between traditional liquids and solid crystals. Liquid crystals can flow, but their molecules have a crystal-like solid orientation.

The liquid crystal is responsible for producing the image that flashes onto the LCD screen. However, they do not glow. Backlight is used to illuminate these crystals.

The display is made up of several tiny blocks of color called pixels. The term is a combination of “picture” and “element”, and represents pixels as small elements that make up a picture of the entire screen. Screens are usually made up of millions of pixels.

Each pixel on the display consists of red, blue, and green light. These lights can be turned on or off quickly to create an overall moving picture or image. LCD touch display suppliers produce high-quality products according to customers’ requirements.
