Shenzhen Hongguang Display Co.,Ltd 10.0 PRECAUTIONS (1) Use fingerstalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (2) You must mount a module using specified mounting holes (Details refer to the drawings). (3) Please make sure to avoid external forces applied to the Source PCB or FPC and D-IC during the process of handling or assembling. If not, It causes panel damage or malfunction. (4) Note that LCD surface are very fragile and could be easily damaged. Do not touch, push or rub the exposed LCD surface with glass, tweezers or...

Shenzhen Hongguang Display Co.,Ltd 10.2 Operating Precautions (1) Be careful for condensation at sudden temperature change. Condensation makes damage to LCD surface or electrical contacted parts. And after fading condensation, smear or spot will occur. (2) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be done by system manufacturers. Grounding and shielding methods may be important to minimized the interference. (3) The electrochemical reaction caused by DC voltage will lead to LCD degradation, so DC drive should be avoided. (4) The LCD...

Shenzhen Hongguang Display Co.,Ltd 10.3 Electrostatic Discharge Control (1) Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly. Keep products as far away from static electricity as possible. (2) Avoid the use work clothing made of synthetic fibers. We recommend cotton clothing or other conductivity-treated fibers. 10.5 Precautions for Strong Light Exposure Strong light exposure causes degradation of polarizer and color...
