The basic principle difference between TFT LCD screen and LCD Panel screen

TFT LCD screens and LCD panels are two common screen technologies in our daily lives, widely used in various devices including televisions, computer monitors, smartphones, tablets, etc. Although they both belong to liquid crystal panel technology, there are some key differences between them.
The basic principles of TFT LCD screen and LCD panel screen:
1. LCD Panel: LCD screens control the transmission and obstruction of light through the rotation of liquid crystal molecules, thereby achieving image panel. This technology uses liquid crystal molecules located between two layers of glass, which can be adjusted by an electric field to change the direction of light and ultimately form an image.
2. Thin Film Transistor Liquid Crystal Panel: TFT LCD screen is a special type of LCD panel screen. Unlike traditional LCDs, TFT LCD screens use thin-film transistors to control the brightness and color of each pixel. This means that each pixel has an independent transistor, which can more accurately control the transmission of light, thereby achieving higher resolution and better image quality.
