1. General Description

The LC370EUN 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 37 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 16.7M(true) colors.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,

2. 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 mana

ement 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.

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 (ExtV

BR-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 (ExtV

BR-B :100%) on condition of continuous operating in LCM state at

25±2°C.

V_

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. ExtVBR-B signal have to input available duty range and sequence.
After Driver ON signal is applied, ExtVBR-B should be sustained from 5% to 100% more than 500ms.
After that, ExtVBR-B 1% and 100% is possible
For more information, please see 3-6-2. Sequence for LED Driver.
