AI Technical Summary
When the existing LCD screens cannot discharge static electricity or are difficult to discharge, the ITO of the upper and lower glasses forms an electric field, which in turn causes the liquid crystal to flip, causing the bottom of the LCD screen to be shadowed.
An LCD screen electrostatic removal structure is designed, including a first glass plate, a second glass plate, an FPC plate and an electrostatic release loop. By cutting off the three sides of the driving IC side on the second glass plate, an avoidance area is formed, and the electrostatic release loop is exposed to the avoidance area. The electrostatic release loop is electrically connected to the FPC board to achieve effective release of static electricity.
Through the design of the electrostatic release loop, static electricity can be effectively transmitted through the FPC board, improving the electrostatic release capability of the LCD screen and avoiding the bottom shadow caused by the liquid crystal flip angle.
