How TFT works and its benefits

TFT LCD Display panel technology has a sandwich-like structure with liquid crystal elements filled between two glass plates. Two polarizer filters, color filters (RGB, red/green/blue), and two alignment layers decide the quantity of light authorized to pass and which colors are formed. Each pixel in an active matrix is paired with a transistor that contains a capacitor, which allows each sub-pixel to retain its charge instead of requiring an electrical charge sent each time it must be changed. The TFT screen layer controls the light flow, a color filter displays the color, and a top layer houses your visible screen.

Benefits and its uses

TFT LCD display panel offers several benefits over other displays (CRT, Plasma). It is light, thin, and energy-efficient, making it feasible for mobile phones, laptops, hang-on-wall LCD TV, flat computer monitors, and other handheld devices. TFT LCDs are also relatively inexpensive, which makes them prevalent in the display world. When we say the LCD type, we mean two kinds of LCDs: Active TFT color display and Monochrome passive display. Before TFT display was invented, the world utilized passive matrix LCD for many years. Passive matrix LCD can only be employed for monochrome displays like calculators, watches (not iWatch), thermostats (not Nest), utility meters, etc. Thanks to TFT LCD, the world is more colorful.
