Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 3 and 4, the present invention provides a glass cover plate, including,
the cover plate comprises a cover plate body 10 and a cover plate body, wherein the cover plate body 10 comprises a first surface 11 and a second surface 12, the stress of the first surface 11 is smaller than that of the second surface 12, the first surface 11 is subjected to inward bending force in a natural state, the second surface 12 is subjected to outward bending force, and the cover plate body 10 is bent towards the first surface 11; and an antireflection film 20 completely covering the second face 20. The cover plate body 10 is made of toughened glass. And tempered again after plating the antireflection film 20. Antireflection film 20 is capable of blocking ion exchange during tempering of second face 12.
According to the invention, the second surface 12 with large stress of the cover plate body 10 is plated with the antireflection film 20 and then is tempered again, the second surface 12 cannot perform ion exchange due to the blocking of the antireflection film 20, and the first surface 11 performs ion exchange, so that the stress is increased, and finally the balance is achieved. The problem of apron crooked is solved.
The antireflection film 20 is made of one or more of silicon dioxide, silicon nitride, niobium oxide, and titanium oxide.
The antireflection film has at least two layers, and since a single layer of the antireflection film 20 hardly achieves a desired effect, a multilayer antireflection film 20 is used in order to achieve zero reflection at a single wavelength or achieve a good antireflection effect in a wide spectral region. Preferably, the antireflection film has 5 to 9 layers, and is formed by stacking two materials with different refractive indexes, wherein the low refractive index material comprises silicon dioxide, and the high refractive index material comprises silicon nitride, niobium oxide and titanium oxide.
The thickness of the antireflection film 20 is 200 to 500 nm.
In the present embodiment, the reflectance of antireflection film 20 is preferably less than 1%. The effect of eliminating the reflected light is good.
