Dot defect is defined as the defective area of the dot area is larger than50% of the dot area.2.The distance between black dot defects or black and bright dot defectsshould be more than 5mm apart.3. Polarizer bubble is defined as the bubble appears on active display area. Thedefect of polarizer bubble shall be ignored if the polarizer bubble appears on theoutside of active display area.4.Mura is checker by 6% ND filter.5.Foreign particle on the surface of the LCM should be ignore.6. Mechanics specificationAs for the outside dimension, weight of the modules, please refer to product specification for more details7. PrecautionPlease pay attention to the following items when you use the LCD Modules:7-1 Do not twist or bend the module and prevent the unsuitable external force for display module during assembly.7-2 Adopt measures for good heat radiation. Be sure to use the module with in the specified temperature.7-3 Avoid dust or oil mist during assembly.7-4 Following the correct power sequence while operating. Do not apply the invalid signal, otherwise, it will cause improper shut down and damage the module.7-5 Less EMI: it will be more safety and less noise.7-6 Please operate module in suitable temperature. The response time & brightness will drift by different temperature.7-7 Avoid to display the fixed pattern (exclude the white pattern) in a long period, otherwise, it will cause image stains.7-8 Be sure to turn off the power when connection of disconnecting the circuit.7-9 Polarizer scratches easily, please handle it carefully.7-10 Display surface never likes dirt of stains.7-11 A dew drop may lead to destruction. Please wipe off and moisture before using module.7-12 Sudden temperature changes cause condensation, and it will cause polarizer damaged.7-13 High temperature and humidity may degrade performance. Please do not expose the module to the direct sunlight and so on.7-14 Acetic acid or chlorine compounds are not friends with TFT display module.7-15 Static electricity will damage the module, please do not touch the module without any grounded device.7-16 Do not disassemble and reassemble the module by self.7-17 Be careful do not touch the rear side directly.Page 6 of 6 7-18 Not strong vibration or shock. It will cause module broken.7-19 Storage the modules in suitable environment with regular packing.7-20 Be careful or injury from a broken display module.7-21 Please avoid the pressure adding to the surface (front or rear side) of modules, because it will cause the display non-uniformity of other function issue.。
