[0033] Attached below figure 1 to attach Figure 4 The present invention will be further described.
[0034] An electromagnetic shielding and sealing method for a display screen with an external touch screen, comprising the following steps:
[0035] a) paste a layer of shielding film 2 on the liquid crystal screen 1, and there is no gap between the shielding film 2 and the liquid crystal screen 1;
[0036] b) Paste a layer of anti-reflection anti-reflection film 3 on the shielding film 2, the size of the anti-reverse anti-reflection film 3 is smaller than the size of the shielding film 2, after the anti-reverse anti-reflection film 3 is pasted, a circle of exposed circles is formed on the periphery of the shielding film 2 Conductive surface;
[0037] c) Paste a circle of conductive foam 4 on the exposed conductive surface on the periphery of the shielding film 2;
[0038] d) Place the liquid crystal screen 1 in the inner cavity of the lower end of the casing 5, the pressin...
