LC320EUA

Product Specification

1. General Description

The LC320EUA is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) 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 (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 8-bit gray scale signal for each dot. Therefore, it can present a palette of more than 16.7Milion colors.

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.

Note 1. 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 be degraded in case of improper thermal management in final product design.

	condition whereas mosaic pattern(8 x 6) is displayed and fV is the frame frequency.
2.	The above spec is based on the basic model.
3.	All of the typical gate voltage should be controlled within 1% voltage level
4.	Ripple voltage level is recommended under ±5% of typical voltage
5.	In case of EPI signal spec, refer to Fig 2 for the more detail.
6.	HVDD Voltage level is half of VDD and it should be between Gamma9 and Gamma10.

Notes :

1.Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 60 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.The life time (MTTF) is determined as the time which luminance of the LED is 50% compared to that of initial value at the typical LED current (ExtVBR-B :100%) on condition of continuous operating in LCM state at 25±2°C.

3.LGD recommend that the PWM freq. is synchronized with One time harmonic of V_sync signal of system. Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected.

4.The duration of rush current is about 200ms. This duration is applied to LED on time.

5.Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied.

6.Ext_PWM Signal have to input available duty range.

Between 99% and 100% ExtVBR-B duty have to be avoided. ( 99% < ExtVBR-B < 100%)

But ExtVBR-B 0% and 100% are available.
