Product Specification

1. General Description

The LD420EUP 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 42.02 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-pi xel color is determined with a 10-bit gray scale signal for each dot. Therefore, it can present a palette of more than 1.06Bilion colors. It has been designed to apply the 10-bit 4-port LVDS interface. It is intended to support Public Display where high brightness, super wide viewing angle, high color gamut, high color depth and fast response time are important.

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 50°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 60°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 60℃. 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± 24Vand V

2°C. The specified current and power consumption are under the typical supply Input voltage

BR (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 I

T spec of fuse is satisfied.

6. Ext_PWM Signal have to input available duty range. Between 99% and 100%

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.
