LP141X6-A1IB LIQUID CRYSTAL DISPLAY

1. GENERAL DESCRIPTION

The LP141X6-A1IB is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent Lamp(CCFL) back light 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 14.1 inch 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 LP141X6-A1IB has been designed to apply the interface method that enables low power, high speed low EMI. Flat Link must be used as a LVDS(Low Voltage Differential Signaling) chip. The LP141X6-A1IB 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 LP141X6-A1IB characteristics provide an excellent flat panel display for office automation products such as mobile industrial computers.

3.1 Electrical Characteristics

The LP141X6-A1IB requires two power inputs. One is employed to power the LCD

www.jxlcd.com

electronics and to drive the TFT array and liquid crystal. The second input which

www.jxlcd.com

powers the CCFL, is typically generated by an inverter. The inverter is an external unit to the LCD.

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

www.jxlcd.com

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 HBb 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

TITLE: LP141X6-A1IB REV. 1 PAGE 19 OF 22

(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

TITLE: LP141X6-A1IB REV. 1 PAGE 20 OF 22

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

www.jxlcd.com

light. Keep the temperature between 5° and 35° 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.
