LC320WXN

Product Specification

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 display type which is 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 arrayed 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(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.

Note1. Ambient temperature condition (Ta = 25 ± 2 °C )

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 40°C condition.

4.The maximum operating temperatures is based on the test condition that the surface temperature

of display area is less than or equal to 68°C 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 . The range of operating temperature may degraded in case of improper thermal management in final product design.

Note 1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 120 minutes at 25±2°C. The specified current and power consumption are under the typical supply Input voltage 24Vand VBR (EXTVBR-B : 100%), it is total power consumption.

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 (EXTVBR-B :100%), on condition of continuous operating at 25± 2°C

5.LGD recommend that the PWM freq. is synchronized with two times harmonic of Vsync signal of system.

6.The duration of rush current is about 10ms.

7.EXTVBR-B is based on input PWM duty of the inverter.

Note: 1. The input of HSYNC & VSYNC signal does not have an effect on normal operation (DE Only Mode). If you use spread spectrum of EMI, add some additional clock to minimum value for clock margin.

2.The performance of the electro-optical characteristics may be influenced by variance of the vertical refresh rate and the horizontal frequency

Timing should be set based on clock frequency.
