LC320WUE
Engineering Specification
1. General Description
The LC320WUE is a Color Active Matrix Liquid Crystal Display with an integral External Electrode Fluorescent
Lamp (EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 31.55 inch diagonally
measured active display area with WUXGA resolution progressive mode (1080 vertical by 1920 horizontal
pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 1.06B(true) colors.
It has been designed to apply the 10-bit 2-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

Notes : The design of the inverter must have specifications for the lamp in LCD Assembly.
The electrical characteristics of inverter are based on High-High Driving type.
The performance of the lamps in LCM, for example life time or brightness, is extremely influenced by
the characteristics of the DC-AC inverter. So, all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch
of the lamp and the inverter (no lighting, flicker, etc) has never been occurred. When you confirm it,
the LCD
