1. General Description
The LC550MUT is a Color Active Matrix Liquid Crystal Display with an integral Source PCB and the nine 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 display type which is operating in the normally black mode. It has a 54.64 inch diagonally
measured active display area with WUXGA resolution progressive mode (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 16.7M 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℃ 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 ℃ 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
degrade in case of improper thermal management in final product design.

Product Specification
Notes :1. Contrast Ratio(CR) is defined mathematically as :
LC550MUT
Liquid Crystal Display
CR =
Surface Luminance at position n with all black pixels
n = the Position number(1, 2, 3, 4, 5). For more information, see FIG 2.
2. Response time is the time required for the display to transition from G(0) to G(255) (Rise Time, TrR)
and from G(0) to G(255) (Decay Time, TrD). For additional information see the FIG. 3.
3. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which
is normal to the LCD module surface. For more information, see the FIG. 4.
4. Gray scale specification
Gamma Value is approximately 2.2. For more information, see the Table 3.

9. Precautions
Please pay attention to the followings when you use this TFT LCD panel.
9-1. Assembly Precautions
(1) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(2) You should adopt radiation structure to satisfy the temperature specification.
(3) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break
by electro-chemical reaction.
(4) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB
pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental
to the polarizer.)
(5) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like
chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives
used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause
chemical damage to the polarizer
(6) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(7) Board ass’y should be put on the mold frame properly.
(8) FFC Cable should be connected between System board and Source PCB correctly.
(9) Mechanical structure for backlight system should be designed for sustaining board ass’y safely.

9-2. Operating Precautions
(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage :
V=±200mV(Over and under shoot voltage)
(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
And in lower temperature, response time(required time that brightness is stable after turned on)
becomes longer
(4) Be careful for condensation at sudden temperature change.Condensation makes damage to polarizer or
electrical contacted parts. And after fading condensation, smear or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be
done by system manufacturers. Grounding and shielding methods may be important to minimized the
interference.
(7) Please do not give any mechanical and/or electrical impact to board assy. Otherwise, it can’t be operated
its full characteristics perfectly.

9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.
Panel ground path should be connected to metal ground.
9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
9-5. Storage
LC550MUT
Liquid Crystal Display
Product Specification
When storing the board ass’y as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the board ass’y to sunlight or fluorescent light. Keep the
temperature between 5°C and 35°C at normal humidity.
(2) The polarizer surface should not come in contact with any other object.
It is recommended that they be stored in the container in which they were shipped.
