Product Specification

1. General Description

The LC420EUG 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 42.02 inch diagonally measured active display area wi th W UXGA res olution (1 080 vertic al by 1920 hor izo ntal pix el arr a y). 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 16.7M(true) 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.

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.

Unit Note

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 : 2 LED array, 525mA/LED array)

3. Each LED array has one anode terminal and five cathode terminals. The forward current(I

) of the anode terminal is 525mA and it supplies 105mA into five strings, respectively

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

5. ∆VFmeans Max VF-Min VFin one Backlight. So VFvariation in a Backlight isn’t over Max. 1.7V

6. 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.

7. 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%.

8. The reference method of burst dimming duty ratio. It is recommended to use synchronous V-sync frequency to prevent waterfall (Vsync x 1 =Burst Frequency) Though PWM frequency is over 182Hz (max252Hz), function of backlight is not affected.
