LC470EUA
Engineering Specification
1. General Description
The LC470EUA 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 46.96 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 1.67M(ture) 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 40ć 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 ć 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 ć. The range of operating temperature may
degrade in case of improper thermal management in final product design.
5. The storage test condition:-20ć temperature/90% humidity to 60ć temperature/40% humidity ;
the operating test condition: 0ć temperature/90% humidity to 50ć temperature/60% humidity.

2. The above spec is based on the basic model.
3. All of the typical gate voltage should be controlled within 1% voltage level
4. Ripple voltage level is recommended under ·5% of typical voltage
5. In case of EPI signal spec, refer to Fig 2 for the more detail.
6. HVDD Voltage level is half of VDD and it should be between Gamma9 and Gamma10.

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 V
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.
