1. General Description
The LC550EUA is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and the four of
Gate Drive IC (GD-IC) at each side. 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 54.64 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 16.7M(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 68ć. 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 25·2¶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.
