messrs. rev. no. issued date. page. product specification model: MTF-TQ28NP911-LB a feb.27,09 23 / 26 g. to protect the lcd panel from external pressure, put covering glass (acrylic board or similar board) to keep appropriate space between them. h. 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. i. property of semiconductor devices may be affected when they are exposed to light possibly resulting in malfunctioning of the ics. to prevent such malfunctioning of the ics, your design and mounting layout done are so that the ic is not exposed to light in actual use. j. strong light exposure causes degradation of color filter. it may not recover k. do not contact with water to avoid metal corrosion. l. when it is not in use, the screen must be turned off or the pattern must be frequently changed by a screen saver. if it displays the same pattern for a long period of time, brightness down/image sticking may develop due to the lcd structure. m. never disassemble lcd product under any circumstances. if unqualified operators or users assemble the product after disassembling it, it may not function or its operation may be seriously affected.
