LT070W02 Liquid Crystal Display
Product Specification 1. Summary
The LT070W02-TME1 is a Board Assembly Product of TFT LCD without any extra system. This Board Assembly utilizes amorphous silicon thin film transistors and a 16:9 aspect ratio. A 7.0" active matrix liquid crystal display allows full color to be displayed. The applications are Portable DVD, Multimedia applications and others AV system.
2. Features
*Utilizes a panel with a 16:9 aspect ratio, which makes the module suitable for use in wide-screen systems. www..com 7.0" screen produces a high resolution image that is composed of 112,320 pixel elements in a stripe *The arrangement. *Wide viewing angle technology is employed. [The most suitable viewing direction is in the 6 o'clock direction.] *By adopting an active matrix drive, a picture with high contrast is realized. *This Board Assembly is accomplished through the use of COG mounting technology. *By adopting a high aperture panel, high transmittance color filter and high transmission polarizing plates, transmittance ratio is realized.

11. PRECAUTIONS
Please pay attention to the following when you use this TFT LCD COG Assembly(Board Ass'y).
11-1. MOUNTING PRECAUTIONS
(1) You must mount a Board Ass'y using packing trays arranged. (2) www..comYou should consider the mounting structure so that uneven force(ex. Twisted stress) is not applied to the Board Ass'y. And the case on which a Board Ass'y is mounted should have sufficient strength so that external force is not transmitted directly to the Board Ass'y. (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 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 describe 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 determined 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 adhesives used to attach front / rear polarizers. 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.
11-2. 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) 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. (4) When fixed patterns are displayed for a long time, remnant image is likely to occur. (5) Sufficient suppression to the electromagnetic interference shall be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference.

12-3. 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.
12-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE
www..com
Strong light exposure causes degradation of polarizer and color filter.
12-5. 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.
12-6. 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.
