LCD Module User Manual Note 1: The data are measured after LEDs are turned on for 5 minutes. LCM displays full white. The brightness is the average value of 9 measured spots. Measurement equipment PR-705 (Φ8mm) Measuring condition: - Measuring surroundings: Dark room - Measuring temperature: Ta=25℃. - Adjust operating voltage to get optimum contrast at the center of the display. Measured value at the center point of LCD panel after more than 5 minutes while backlight turning on. Note 2: The luminance uniformity is calculated by using following formula. △Bp = Bp (Min.) / Bp (Max.)×100 (%) Bp (Max.)...

LCD Module User Manual 6 CTP Application Precautions 6.1 CTP Mounting Precaution 6.1.1 Bezel Mounting (Figure 1) - The bezel window should be bigger than the CTP active area. It should be≥0.5mm each side. - Gasket should be installed between the bezel and the CTP surface. The final gap should be about 0.5~1.0mm. - It is recommended to provide an additional support bracket for backside support when necessary (e.g. slim type TFT module without mounding structure). They should only provide appropriate support and keep the module in place. - The mounting structure should be strong enough to prevent...

LCD Module User Manual 6.2.1 The product made of glass. Do not subject it to a mechanical shock by dropping it from a high place, etc. 6.2.2 Do not apply excessive or uneven force to the product since this may damage to the performance. 6.2.3 If the display surface is contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If still not completely clear, moisten cloth with Isopropyl alcohol or Ethyl alcohol solvents. Solvents other than those mentioned above may damage the product. Especially, do not use Water, Ketone, Aromatic solvents. 6.2.4 Do not attempt to disassemble...
