1. General Description

The LC420EUJ is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and Gate implanted on Panel (GIP). 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 41.92 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 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. 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.

notes:

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℃ condition.

4. The maximum operating temperature is based on the test condition that the surface temperature of display area is less than or equal to 68 ℃ 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

degrade in case of improper thermal management in final product design.

1. All GND(ground) pins should be connected together to the LCD module‟s metal frame.

2. All VLCD (power input) pins should be connected together.

3. All Input levels of LVDS signals are based on the EIA 644 Standard.

4. #1~#6 & #8~#10 NC (No Connection): These pins are used only for LGD (Do not connect)

5. Specific pin No. #44 is used for “No signal detection” of system signal interface.

It should be GND for NSB(No Signal Black) during the system interface signal is not.

If this pin is “H”, LCD Module displays AGP(Auto Generation Pattern).

notes: 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

3. Spread Spectrum Rate (SSR) for 50KHz ~ 100kHz Modulation Frequency(FMOD) is calculated by

(7 – 0.06*Fmod), where Modulation Frequency (FMOD) unit is KHz. LVDS Receiver Spread spectrum Clock is defined as below figure

※ Timing should be set based on clock frequency.

LC420EUJ

Product Specification

※ Please pay attention to the followings when you set Spread Spectrum Rate(SSR) and Modulation Frequency(FMOD)

1. Please set proper Spread Spectrum Rate(SSR) and Modulation Frequency (FMOD) of TV system LVDS

output.

2. Please check FOS after you set Spread Spectrum Rate(SSR) and Modulation Frequency(FMOD) to avoid

abnormal display. Especially, harmonic noise can appear when you use Spread Spectrum under FMOD 30

KHz.
