VATN LCD Introduction

The Vertical Alignment (VA) display is a type of LCD technology in which the liquid crystals naturally align vertically to the glass substrates. When no voltage is applied to LCD panel, the liquid crystals remain perpendicular to the substrate creating a black display between crossed polarizer. 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. The following is work theory of VATN vs. conventional
