1. General Description

The LC320WXN 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 type display operating in the normally black mode. It has a 31.51 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, thus presenting a palette of more than 16.7M(true) colors. It has been designed to apply the 8-bit 1-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.

The ripple voltage of the power supply input voltage is under 0.5 Vp-p. LPL recommend Input Voltage is

24.0V · 5%.

2. Electrical characteristics are determined within 30 minutes at 25·2¶C.

The specified currents are under the typical supply Input voltage 24V.

3. The brightness of the lamp after lighted for 5minutes is defined as 100%. TS is the time required for the brightness of the center of the lamp to be not less than 95% at typical current.

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.

4. Specified Values are for a single lamp which is aligned horizontally. The life time is determined as the time which luminance of the lamp is 50% compared to that of initial value at the typical lamp current (V

Notes: 1. The pin no 9 is an option pin for DISM or LG format. ( VESA Format = “GND” / JEIDA Format =“VCC”)

Please refer to Appendix for further details.

2. The pin no 10 is an option pin for DCR Function ( Enable = “VCC” / Disable =“GND”)

3. The pin no 30 is LCD Test option. LCM operates “AGP” (Auto Generation Pattern) or “NSB” (No Signal Black) is case that LVDS signals are out of frequency or abnormal condition in spite of 12 volt power supply. LPL recommends “NSB”. ( AGP : “VCC” or “OPEN” / NSB : “GND” )

4. All GND (ground) pins should be connected together, which should be also connected to the LCD

module’s metal frame.

5. All V

(power input) pins should be connected together.
