Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a structure of a display module capable of preventing a dustproof film from curling. Background Art

[0002] AMOLED products are widely used in the display market, such as smart bracelets, smart watches, smart homes, e-cigarette products, etc., and with the advancement of technology, more and more wearable devices such as watches and bracelets are becoming increasingly popular. Now many watches and bracelets are AF waterproof and oil-proof, but in daily life and outdoor activities, there is still a lot of dust that will adhere to the display. Therefore, in order to prevent dust, a layer of protective film is generally attached to the surface of the display. However, the dust-proof film is directly exposed to the outside, and its corners and the corners of the display are very prone to curling. Once curling occurs, the back of the dust-proof film will adhere to dust and cannot be used. Therefore, the service life of the dust-proof film is not long, and the dust-proof effect is not good.
