[0002] With the continuous improvement of the performance of electronic products, smart terminals have higher and higher requirements for anti-static and anti-electromagnetic interference of display modules. It is very important to improve the anti-static and anti-interference capabilities of electronic products. At present, the common anti-static method is to attach a piece of copper foil above the IC and FPC, and increase the grounded copper area on the FPC accordingly, which is bonded with the copper foil to form an electromagnetic shielding layer. The copper foil is used to solve the problem of radio frequency interference. An insulating tape is added between the copper foil and the IC to prevent the copper foil from short-circuiting with the IC. However, this design requires an additional exposed copper area on the FPC, which will increase its production cost. Utility Model Content
