  • Page 6 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 using holes arranged in four cornersor four sides. (2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the module.
  • Page 7 9-2. 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) 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.
  • Page 8 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°C and 35°C at normal humidity.
