Ver 0.3 July 5, 2000 Page 4/24 1. General Description The LM181E1-H2MN 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 black mode. This TFT-LCD has a 18.1 inch diagonally measured active display area with SXGA resolution(1024 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 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16,777,216 colors. The LM181E1-H2MN has been designed to apply the interface method that enables low power, high speed low EMI. FPD Link must be used as a LVDS(Low Voltage Differential Signaling) chip. The LM181E1-H2MN is intended to support applications where thin thickness, wide viewing angle, low power are critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LM181E1-H2MN characteristics provide an excellent flat panel display for office automation products such as monitors.

Ver 0.3 July 5, 2000 Page 21/24 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 user holes arranged in four corners. (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 with a transparent protective plate in order to protect the polarizer LC cell. 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 polarizer at high temperature and the latter causes circuit break by electro-chemical reaction. (6) Do not touch, push or rub the exposed polarizer with glass, tweezers or anything harder than HB pencil head 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 petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizer. Do not use acetone, toluene 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 malfunction 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 co-work together.
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 I/F pin directly.
9.4 PRECAUTION 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 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. Alpha Point Ltd. P.O. Box 41 http://www.alpha.fi Tel.: +358-9-34 64 34 1 Fax: +358-9-34 64 34 2
Ver 0.3 July 5, 2000 Page 22/24
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 adhesive tape. If some stress is applied to rub the protection film against the polarizer during the time you peel off the film, the adhesive tape 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 adhesive tape still on the polarizer after the protection film is peeled off. (4) You can remove the adhesive easily. When the adhesive 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.
