1. General Description
The LC320EXJ is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and Gate
implanted on Panel (GIP). The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. It has a 31.5 inch diagonally measured
active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7M(6bit + A-FRC) colors.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,

2. Temperature and relative humidity range are shown in the figure below. Wet bulb temperature
should be Max 39 ¶C and no condensation of water.
3. Gravity mura can be guaranteed below 40ć condition.
4. The maximum operating temperature is based on the test condition that the surface temperature
of display area is less than or equal to 68 ć with LCD module alone in a temperature controlled
chamber. Thermal management should be considered in final product design to prevent the surface
temperature of display area from being over 68 ć. The range of operating temperature may
degrade in case of improper thermal management in final product design.

Notes :
1. All GND (Ground) pins should be connected together to the LCD module’s metal frame.
2. All VLCD (power input) pins should be connected together.
3. All Input levels of LVDS signals are based on the EIA 644 Standard.
4. These pins are used only for LGD (Do not connect)
5. Specific pin No. #30 is used for “No signal detection” of system signal interface.
It should be GND for NSB (No Signal Black) while the system interface signal is not.
If this pin is “H”, LCD Module displays AGP (Auto Generation Pattern).
