Understanding the Structure of a TFT LCD Display
A TFT LCD Display (Thin-Film Transistor Liquid Crystal Display) relies on a combination of liquid crystal material, polarized filters, thin-film transistor layers, and a backlight system. Its architecture allows each pixel to be individually controlled by its own transistor, enabling rapid response, high resolution, precise color reproduction, and stable performance.
Core Components
-
TFT Glass Substrate
Acts as the foundation for individual pixel transistors. -
Liquid Crystal Layer
Controls the passage of light through electrical modulation. -
Color Filter
Separates light into red, green, and blue subpixels. -
Backlight Unit (BLU)
Provides illumination, most commonly using LED sources. -
Polarizers
Manage light orientation to generate visible images. -
