MVA (Multi-domain Vertical Alignment) displays can offer wide viewing angles, good black depth, fast response times, and good color reproduction and depth. Each pixel within a MVA type TFT consists of three sub-pixels (Red, Green and Blue). Each of these sub-pixels is divided further into two or more sub-pixels, where the liquid crystals are randomly lined up due to the ridged polarized glass.
How it works:
1. Light is generated from a backlight source, typically LED. Light is generated as close to white spectrum.
2. Driver ICs will logically control to activate pixels on or off.
> Inactive LCD pixels will block light.
> Active pixels will open with the direction of the light to let it pass through.
3. Top Circular polarization is added to enhance contrast.
4. Color is added through a color filter to all sub-pixels (R,G,B).
TFT (Thin-Film Transistor) Displays are active-matrix LCDs with full RGB color screens. These screens feature bright, vivid colors and have the ability to show fast animations, complex graphics and crisp custom fonts. TFTs are perfect displays for providing a rich user interface for all types of products. While typically used in consumer devices like personal DVD players and handheld devices, TFTs are also well suited for industrial application.
