Embodiment 2
[0036] The present invention also provides an electronic device, including the glass cover plate in Embodiment 1. For electronic equipment using such a glass cover plate, an anti-reflection film 20 is coated on the second surface 12 of the cover plate with high stress and tempered again. The second surface cannot be ion-exchanged due to the barrier of the anti-reflection film 20, and the first surface 11 is ion-exchanged. , so that the stress increases and finally reaches equilibrium. Fixed an issue with bent covers. The post-processing of the cover plate is facilitated, and the overall visual effect of the display panel is improved.
[0037] In the present invention, an anti-reflection film is coated on the side with high stress of the cover plate and tempered again. The side with the anti-reflection film cannot perform ion exchange due to the blocking of the anti-reflection film, while the other side undergoes ion exchange, thereby increasing the stress and finally achievin...

Abstract
The invention discloses a glass cover plate and electronic equipment, wherein the glass cover plate comprises a cover plate body and an antireflection film; the cover plate body comprises a first surface and a second surface; the stress of the first surface is smaller than that of the second surface; in a natural state, the first surface is subjected to an inward bending force, the second surface is subjected to an outward bending force, and the cover plate body is bent towards the first surface; and the antireflection film completely covers the second surface. The large-stress surface of the cover plate is plated with the antireflection film and tempered again, the surface with the antireflection film cannot be subjected to ion exchange due to blocking of the antireflection film, and the other surface is subjected to ion exchange, so that the stress is increased, and finally balance is achieved. The problem that the cover plate is bent is solved. Later processing of the cover plate is facilitated, and the overall visual effect of the display panel is improved.
Description
technical field [0001] The invention relates to the technical field of display panels, in particular to a glass cover plate and electronic equipment. Background technique [0002] In order to enhance the strength of the cover plate, the glass cover plate of the vehicle generally needs to be chemically tempered; figure 1 and figure 2 As shown, during the chemical tempering process of the flat glass 10', the tempering depths of the front and back sides are often inconsistent, and the stress on the first side 11' is smaller than that of the second side 12', thus causing the glass to warp. If no treatment is done, it is not conducive to the post-processing of the glass 10', affects the appearance of the cover plate, and even affects the display effect of the display panel. [0003] In view of this, it is urgent to improve the existing glass cover to reduce the stress difference between the two sides of the tempered cover. Contents of the invention [0004] The invention di...
