Abstract
A liquid crystal display module with ultra-strong static disturbance prevention capacity comprises an ITO transparent conducting film, two pieces of conducting foam, an LCD display screen, FPC connectors, an LED backlight source, a PCB, an FFC and two COG IC chips of the same type. The LCD display screen is bound through the COG IC chips of the same type. The COG IC chips are connected with the PCB through the two FPC connectors. The LED backlight source is arranged below the LCD display screen. The ITO transparent conducting film is plated on the upper surface of the LCD display screen and connected with the PCB through the two pieces of conducting foam. Resistance-capacitance devices are arranged on the PCB and connected with an external MCU through the FFC. The liquid crystal display module has the advantages that due to the adoption of the COG binding technology, the structure is compact, the size is small, and the power consumption is extremely low; the liquid crystal display module can work at night due to the LED backlight source, the ITO layer on surface of a piece of upper glass of a product is connected to a grounding layer of the PCB through a piece of conductive cloth, and therefore a static shielding protection cover can be formed outside the module, and the antistatic capacity index can be higher than 16kV in the contact discharge process.
