Note 1 Note 1 Note 1 Note 1 Note 3 Note 1: SPI Interface is only to set up the initial code in LCM driver IC register. Note 2: There had been default initial code stored in LCD driver IC at Sync Mode operation, and if customer needs to revise the default initial code to change gamma or Vcom voltage, then SPI interface is needed. Note 3: Different from Sync mode, there is no default initial code in driver IC in DE mode, so initial code has to be setup via SPI interface at DE mode. Messrs.

Evaluation and assessment made two hours after return to room temperature (25 ± 5°C). The LCDs subjected to the test must not have dew condensation. The test pattern is gray scale and the operating voltage sweep from Vth to Vsat variable. The non-uniformity and other appearance are checked in LCD. 11.1.4 Result Evaluation Criteria There should be no change which might affect the practical display function when the display quality test is conducted under normal operating condition. 11.1.5 Life time Life time expectancy of LCD Panel is approximately 50,000 hours under the room environment. D efinition on the termination of life time is deterioration of contrast ratio by one fifth against initial value. 11.1.6 Basic rule for Reliability test * Place all the samples under room temperature & humidity for 24 hours after reliability stressing. * Room environment means 25+/-10°C, 45+/-20%RH * There should be no condensation during the test. * One LCD module shall be used for one test item only and once. 11.1.7 Judgment Criteria for reliability test No. 1-2 * Contrast (or Brightness) ratio variation is within 50% of the initial value. * No abnormal function * No extreme decay on appearance 11.1.8 Life time Display (LCD module) : Life time expectancy of LCD Panel is approximately 50,000 hours under the room environment. 11.2 Touch panel Reliability No. Items Min.

PRECAUTIONS 12.1 Operation Burn-in sometimes happens when the same character was displayed at along time. Therefore, to prevent Burn-in, it is recommended to set up a Screen-saver function. 12.2 Safety The liquid crystal in the LCD is poisonous, DO NOT put it in your mouth. If the liquid crystal to uches your skin or clothes, wash it off immediately using soap and water. 12.3 Handling a. The LCD module shall be installed flat, without twisting or bending. b. COF or FPC has narrow pattern width, so easily become open circuit by external force. DO NOT apply pressure to COF or FPC especially in bending area. c. To avoid damage in appearance or malfunction, DO NOT subject the module to mechanical shock or to excessive force on its surface. d. The polarizer attached to the display is very easy to damage, handle it with care to avoid scratching. e. To avoid contamination on the display surface, DO NOT touch the display surface with bare hands. f. Provide a space so that the LCD module does not come into contact with other components. Messrs. Product Specification Model: MTF-TQ35SP741-AV Rev. No. Issued Date. Page. C Jan.16, 08 28 / 31 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. Messrs. Product Specification Model: MTF-TQ35SP741-AV Rev. No. Issued Date. Page. C Jan.16, 08 29 / 31 12.4 Static electricity Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. a. The LCD module shall be installed flat, without twisting or bending. Ground soldering iron tips, tools and testers when they operate. b. Ground your body when handling the products. c. DO NOT apply voltage to the input terminal without applying power supply. d. DO NOT apply voltage that exceeds the absolute maximum rating. e. Store the products in an anti-electrostatic container. f. Peel off protect tape, attached to polarizer, slowly to minimize ESD damage. 12.5 Storage Store the products in a dark place at +5 ~ +25 degree C, low humidity (50%RH or less). DO NOT store the products in an atmosphere containing organic solvents or corrosive gases. 12.6 Cleaning a. DO NOT wipe the polarizer with dry cloth, as it might cause scratch. b. Wipe the polarizer with a soft cloth soaked with petroleum IPA, other chemical might damage. 12.7 Waste When dispose of LCD module, manage it at the production waste according to the relevant laws and regulations.
