1. General Description
The LC550EUN 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 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 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 16.7Milion 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.

The following items are maximum values which, if exceeded, may cause faulty operation or permanent damage
to the LCD module.
2. Absolute Maximum Ratings
Table 1. ABSOLUTE MAXIMUM RATINGS
1. Ambient temperature condition (Ta = 25 ± 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.

3-1. Electrical Characteristics
It requires two power inputs. One is employed to power for the LCD circuit. The other Is used for the LED
backlight and LED Driver circuit.
Table 2. ELECTRICAL CHARACTERISTICS
1. The specified current and power consumption are under the VLCD=12.0V, Ta=25 ± 2°C, fV=60Hz
condition, and mosaic pattern(8 x 6) is displayed and fV is the frame frequency.
2. The current is specified at the maximum current pattern.
3. The duration of rush current is about 2ms and rising time of power input is 0.5ms (min.).
4. ExtVBR-B signal have to input available duty range and sequence.
After Driver ON signal is applied, ExtVBR-B should be sustained from 5% to 100% more than 500ms.
After that, ExtVBR-B 1% and 100% is possible
For more information, please see 3-6-2. Sequence for LED Driver.
5. Ripple voltage level is recommended under ±5% of typical voltage

Table 3. ELECTRICAL CHARACTERISTICS (Continue)
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 VBR (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.
3. The duration of rush current is about 200ms. This duration is applied to LED on time.
4. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied.

3-3. Signal Timing Specifications
Table 6 shows the signal timing required at the input of the LVDS transmitter. All of the interface signal
timings should be satisfied with the following specification for normal operation.
Table 6. TIMING TABLE (DE Only Mode)
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.

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

abnormal display would be shown. There is no reliability problem.
4. T5 should be measured after the Module has been fully discharged between power off and on period.
5. If the on time of signals (Interface signal and user control signals) precedes the on time of Power (VLCD),
it will be happened abnormal display. When T6 is NC status, T6 doesn’t need to be measured.
