LCD Panel Specification This specification applies to the 20.1 inch-wide Color TFT-LCD Module M201EW02. The display supports the WSXGA+ (1680(H) x 1050(V)) screen format and 16.7M colors (RGB 6-bits+Hi-RFC data). All input signals are 2 Channel LVDS interface compatible. This module does not contain an inverter card for backlight.
Monitor Block Diagram The LCD MONITOR will contain a main board, a power board, and key board which house the flat panel control logic, brightness control logic and DDC. The power board will provide AC to DC Inverter voltage to drive the backlight of panel and the main board chips each voltage.
