4 2. ABSOLUTE RATINGS OF ENVIRONMENT Note (1) Temperature and relative humidity range is shown in the figure below. (a) 90% RH Max. (Ta 40ºC) (b) Wet-bulb temperature should be 39ºC Max. (Ta > 40ºC) (c) No condensation. (2) The maximum operating temperature is based on the test condition that the surface temperature of display area is less than or equal to 60ºC with LCD module alone in a temperature controlled chamber. Thermal management should be considered in final product design to prevent the surface temperature of display area from being over 60ºC. The range of operating temperature may degrade in case of improper thermal management in final product design. (3) 11 ms, half sine wave, 1 time for ±X, ±Y, ±Z. (4) 10~200 Hz, 10 min, 1 time each X, Y, Z. (5) At testing Vibration and Shock, the fixture in holding the module has to be hard and rigid enough so that the module would not be twisted or bent by the fixture. VT420 Liquid Display User Guide

20 6. HANDLING PRECAUTIONS (1) The panel is made of glass, which may be broken or cracked if drop or bump on hard surface. Handle with extra care of the module. (2) Use a soft dry cloth without chemicals for cleaning, for the surface of polarizer is very soft and easily scratched. (3) It is recommended to assemble or install module into the user s system in clean working areas. The dust and oil may cause electrical short or worsen the polarizer. (4) Since contact with water may cause discoloration or spots, wipe off the water immediately when drop on the surface of the panel. (5) Always follow the correct power-on sequence when the LCD module is turned on. This can prevent the damage and latch-up of the CMOS LSI chips. (6) Take care of static electricity and handle with caution to prevent the damage of CMOS LSI in the module. (7) Do not pull the I/F connector in or out while the module is operating. (8) Moisture can easily penetrate into LCD module and may cause the damage during operation. (9) When handling LCD modules and assembling them into cabinets, please noted that longterm storage in the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent, adhesive, resin, etc. May cause corrosion and discoloration of the LCD module. (10) When ambient temperature is lower than 10, the display quality might be reduced. For example, the response time will become slow, and the starting voltage of CCFL will be higher than that of room temperature. VT420 Liquid Display User Guide
