Product Specification

1. General Description

The LP154WX5 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 15.4 inches diagonally measured active display area with WXGA resolution(800 vertical by 1280 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 LP154WX5 has been designed to apply the interface method that enables low power, high speed, low EMI. The LP154WX5 is intended to support applications where thin thickness, low power are critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP154WX5 characteristics provide an excellent flat display for office automation products such as Notebook PC.

3. Electrical Specifications 3-1. Electrical Characteristics

The LP154WX5 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.

2. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.

3. The typical operating current is for the typical surface luminance (LWH) in optical characteristics.

4. Define the brightness of the lamp after being lighted for 5 minutes as 100%, Ts is the time required for the brightness of the center of the lamp to be not less than 95%.

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.

Note)

6. The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform.(Asymmetrical ratio is less than 10%) Please do not use the inverter which has asymmetrical voltage and asymmetrical current and spike wave. Lamp frequency may produce interface with horizontal synchronous frequency and as a result this may cause beat on the display. Therefore lamp frequency shall be as away possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference.

7. It is defined the brightness of the lamp after being lighted for 5 minutes as 100%. TS is the time required for the brightness of the center of the lamp to be not less than 95%.

8. The lamp power consumption shown above does not include loss of external inverter. The applied lamp current is a typical one.

9. Requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp, are following. It shall help increase the lamp lifetime and reduce leakage current. a. The asymmetry rate of the inverter waveform should be less than 10%. b. The distortion rate of the waveform should be within √2 ±10%. * Inverter output waveform had better be more similar to ideal sine wave.

* Asymmetry rate:

I p

| I p – I –p | / I

* 100%

rms

10. Inverter open voltage must be more than lamp voltage for more than 1 second for start-up. Otherwise, the lamps may not be turned on. ※ Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter has abnormal action. Because leakage current is occurred between lamp wire and conducting tape.

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 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. (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 polarizer 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 soaks with petroleum benzene. Normal-hexane is recommended for cleaning the

www.jxlcd.com

used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they

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.

9-2. OPERATING PRECAUTIONS

(9) Do not open the case because inside circuits do not have sufficient strength.

adhesives

cause

(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.

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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.

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.
