Product Specification
1. General Description
The LC550EUF is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
b ac k l i g ht s ys t em . T he m a t r i x em p l o ys a - S i T h i n F i lm T r an s is t or a s t he a c t i v e e l em en t .
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 10-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 1.06Bilion colors.
It has been designed to apply the 10-bit 4-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.

Note1. Ambient temperature condition (Ta = 25 r 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 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.

Notes :The design of the LED driver must have specifications for the LED array in LCD Assembly.
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◦ Jabse Service Manual Search 2026 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
