1. General Description

The LC420DUE is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) ba ck li g ht s ys te m. T he m a tr ix e mp l oys a - Si Th in Fi lm T ran s is t or as t h e a ct i ve ele m en t . It is a transmissive display type which is 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 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 16.7Million colors. It has been designed to apply the 8-bit 2-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.

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.

The electrical characteristics of LED driver are based on Constant Current driving type. The performance of the LED in LCM, for example life time or brightness, is extremely influenced by the characteristics of the LED Driver. So, all the parameters of an LED driver should be carefully designed. When you design or order the LED driver, please make sure unwanted lighting caused by the mismatch of the LED and the driver (no lighting, flicker, etc) has never been occurred. When you confirm it, the LCD– Assembly should be operated in the same condition as installed in your instrument.

1. Electrical characteristics are based on LED Array specification.

2. Specified values are defined for a Backlight Assembly. (IBL :10 LED array/LCM)

3. Each LED array has 1 anode terminal and 1 cathode terminal. The forward current (IF) of the anode terminal is 285mA and it supplies 380mA into one string, respectively

4. The forward voltage (VF) of LED array depends on ambient temperature (Appendix-VI)

5. Maximum level of power consumption is measured at initial turn on. Typical level of power consumption is measured after 1hrs aging at 25 ± 2°C.

6. The life time (MTTF) is determined as the time at which brightness of the LED is 50% compared to that of

initial value at the typical LED current on condition of continuous operating at 25 ± 2°C, based on duty 100%.

7. The reference method of burst dimming duty ratio. It is recommended to use synchronous V-sync frequency to prevent waterfall (Vsync * 2 =Burst Frequency) Though PWM frequency is over 182Hz (max252Hz), function of backlight is not affected.

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

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.

Product Specification

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

LC420DUE

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.
