Problems solved by technology

Although the hardness can be improved to a certain extent by depositing a layer of diamond-like carbon film on the surface of the glass substrate, due to the influence of the light transmittance of the diamond-like carbon film (DLC) layer itself, its thickness can only reach 5nm-20nm to ensure the transparency. Light rate, and it is also because the thickness is too small, it is still easy to be worn out during use, which affects the overall wear resistance of the product

Embodiment Construction

[0018] The technical solutions of the present invention will be further specifically described below through specific embodiments and accompanying drawings, but the present invention is not limited to these embodiments.

[0019] Such as figure 1 and figure 2 As shown, this is a cover plate with high wear resistance and light transmittance. The cover plate includes a transparent substrate 1. The transparent substrate 1 includes a front side and a back side. 2 surfaces with DLC-C ox Membrane 3. The transmittance of light can be improved by being provided with an anti-reflection coating layer 2, thereby further ensuring the effect of light transmittance, and by being provided with DLC-C ox The purpose of film layer 3 is to more effectively improve the wear resistance of the product, and at the same time ensure high light transmittance, achieving both high wear resistance and high light transmittance, making light transmittance The rate can reach more than 99%. Also availabl...

Abstract

The invention relates to a cover plate with high wear resistance and high light transmittance and belongs to the technical field of glass surface treatment. The cover plate with high wear resistance and high light transmittance is used for solving the problem that how to achieve the effects of high wear resistance and high light transmittance simultaneously. The cover plate with high wear resistance and high light transmittance, provided by the invention, comprises a transparent base plate, wherein the transparent base plate comprises a front face and a back face. The cover plate is characterized in that the front face of the transparent base plate is provided with an anti-reflection film layer, and a DLC-Cox film layer is arranged on the surface of the anti-reflection film layer. The cover plate can simultaneously have the effects of high light transmittance and high wear resistance, and the light transmittance can reach over 99%; and the thickness can reach 100nm to 500nm, so that the thickness of the DLC-Cox film layer can be effectively improved, and the overall wear resistance is guaranteed.

Description

technical field [0001] The invention relates to a cover plate with high wear resistance and light transmittance, which belongs to the technical field of glass surface treatment. Background technique [0002] Protective glass is widely used in various touch screens and camera lenses. In order to achieve the purpose of protection without affecting the performance of the product, the protective glass is required to have good light transmission, and also has certain toughness and hardness requirements, so that it can Ensure that the protective glass has sufficient surface strength to prevent scratches and maintain good visual effects. [0003] However, the Mohs hardness of ordinary soda-lime glass substrates is between 5.5-6, and the Mohs hardness of aluminosilicate glass substrates can reach 6.5, but the light transmittance of the glass substrates is only about 90%. , due to its low light transmittance, it will affect the optical performance of the entire product. As an alter...
