Liquid Crystal Display

Product Specification

1. General Description

The LM151X4-A3 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a
transmissive type display operating in the normally white mode. This TFT-LCD has a 15.1 inchs diagonally
measured active display area with XGA resolution(768 vertical by 1024 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
brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus, presenting a
palette of more than 262,144 colors.
The LM151X4-A3 has been designed to apply the TTL interface method.
The LM151X4-A3 LCD is intended to support applications where high brightness, wide viewing angle, high
color saturation, and high color depth are very important. In combination with the vertical arrangement of
the sub-pixels, the LM151X4-A3 characteristics provide an excellent flat panel display for office automation
products such as monitors.

3. Electrical Specifications
3-1. Electrical Characteristics

The LM151X4-A3 requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter.
The inverter is an external unit to the LCD.

while 64 gray pattern is displayed
The max. power consumption is measured while full black pattern is displayed.

2. The variance of the voltage is

±10%.

3. The transformer output voltage in the inverter must be high considering to the loss of
the ballast capacitor in the inverter.

4. The lamp power consumption shown above does not include loss of external inverter.

5. The life time is determined as the time at which brightness of lamp is 50% compare to
that of initial value at the typical lamp current on condition of continuous operating

3-5. Color Input Data Reference

The brightness of each primary color(red, green and blue) is based on the 6-bit gray scale data input for the
color; the higher the binary input, the brighter the color. The table below provides a reference for color versus
data input.

Notes 1. Contrast Ratio (CR) is defined mathematically as:

(Surface Luminance with all white pixels)
(Surface Luminance with all black pixels)

Contrast ratio shall be measured at the center of the display (Location 1).

2. The Luminance is luminance value at center point with full white screen.

9.PRECAUTIONS

Please pay attention to the followings when you use this TFT LCD module.

9.1 MOUNTING PRECAUTIONS

(1) You must mount a module using holes arranged in four corners or four sides.
(2) You should consider the mounting structure so that uneven force (ex. twisted stress) is not applied
to the module.
And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach a transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polalizer at high temperature and the latter causes circuit
break by electro-chemical reaction.
(6) 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.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials
like chamois soaked with petrolium benzene. Normal-hexane is recommended for cleaning the
adhesives used to attach front / rear polarizers. Do not use acetone, toluen and alcohol because
they cause chemical damage to the polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.

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) A module has high frequency circuit. If you need to shield the electromagnetic noise, please do in
yours. When a Back-light unit is operating, it sounds. If you need to shield the noise, please do in yours.

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.

9.4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE

Strong light exposure causes degradation of polarizer and color filter.

9.5 STORAGE

When storing modules as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the
temperature between 5
(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.

 and 35 at normal humidity.

9.6 HANDLING PRECAUTIONS FOR PROTECTION FILM

(1) When the protection film is peeled off, static electricity is generated between the film and polarizer.
This should be peeled off slowly and carefully by people who are electrically grounded and with well
ion- blown equipment or in such a condition, etc..
(2) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied
to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to
remain on the polarizer.
Please carefully peel off the protection film without rubbing it against the polarizer.
(3) When the module with protection film attached is stored for a long time, sometimes there remains a
very small amount of glue still on the polarizer after the protection film is peeled off.
(4) You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is
recognized, please wipe them off with absorbent cotton waste or other soft material like chamois
soaked with normal-hexane
