FAQ - What is VATN LCD Display?

VATN LCD Display (Vertically Aligned Twisted Nematic) is just another type of LCD (liquid crystal display) module but with a high contrast ratio of 1000:1.

It is a negative mode display with a transmissive polarizer.

VATN LCD Display Technology 

In VATN LDC Display liquid crystals naturally align vertically to the glass substrates. When no voltage is applied, the liquid crystals remain perpendicular to the substrate, creating a black display between crossed polarizers. When voltage is applied, the liquid crystals shift to a tilted position, allowing light to pass through and create a gray-scale display depending on the amount of tilt generated by the electric field.
