LCD Module User Manual the electric circuit of LCD module. Only clean LCD with a soft dry cloth, Isopropyl Alcohol or Ethyl Alcohol. Other solvents (e.g. water) may damage the LCD. Never add force to components of LCD module. It may cause invisible damage or degrade the module's reliability. When mounting LCD module, please make sure it is free from twisting, warping and bending. Do not add excessive force on surface of LCD, which may cause the display color change abnormally. LCD panel is made with glass. Any mechanical shock (e.g. dropping from high place) will damage the LCD module....

LCD Module User Manual As the CTP assembling on the countersink area with double side adhesive. The countersink area should be flat and clean to ensure the double side adhesive installation result. The Bezel is recommend to keep a gap (≥0.3mm each side) around the cover lens for tolerance. It is recommended to provide an additional support bracket with gasket for backside support when necessary (e.g. 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 external uneven...
