What is a TFT LCD?

A TFT LCD, or Thin-Film Transistor Liquid Crystal Display, is a type of flat-panel display commonly used in electronic devices such as computer monitors, television screens, mobile phones, and other handheld devices. It employs thin-film transistor technology to improve image quality and provide better contrast and response times compared to older LCD technologies.
In a TFT LCD, each pixel is controlled by its own transistor, which allows for more precise control over the individual pixels. This results in sharper images, better color reproduction, and faster refresh rates. TFT LCDs are known for their thin profile, lightweight design, and low power consumption, making them ideal for portable devices.

The "liquid crystal" part of the name refers to the material used in the display, which is a special type of organic compound that can change its optical properties in response to an electric current. When voltage is applied to specific pixels, the liquid crystal molecules align in such a way that either block or allow light to pass through, creating the desired image.
