The warped screen of the tablet is caused by the incorrect process adopted by the manufacturer. The touch screen of the tablet is made of glass material, and the surface flatness is very good. The face frame of the tablet is generally made of plastic. There will definitely be a certain amount of deformation during injection molding, just the degree of deformation. Since the size of the tablet is relatively large, the cumulative deformation will be relatively large, so there will definitely be relatively large stress after the touch screen and the face frame are bonded, and the production Businessmen generally use double-sided adhesive tape. The bonding strength of the double-sided adhesive tape cannot reach the required strength, so the screen warping phenomenon will definitely occur. Therefore, we found that almost all tablet computers of all brands have screen warping, which is caused by inherent deficiencies in craftsmanship. You can check that Dongguan Asia Technology Co., Ltd. has relatively good and mature solutions in this field.
