Problems solved by technology

[0003] At present, especially for mobile phones and other electronic products, some methods of preventing blue light are to paste a layer of protective film on the surface of the cover. After the film is pasted, this will reduce the light transmittance, and the film is also prone to scratches that affect the visual effect.
There are also coatings formed by coating the surface of glass and other display panels such as sputtering, vapor deposition, and vapor deposition. For example, a Chinese patent application (publication number: CN109626840A) discloses a blue light cut-off glass coating. The preparation method, specifically related to the anti-blue light glass, is formed by orderly and alternately stacking silicon oxide layers and titanium oxide layers on the surface of the glass, and the silicon oxide and titanium oxide layers are all set in an amorphous state, and have an In the spectral wavelength range, the intensity of the blue light part is reduced by 20%, the UV cut-off rate is 100%, and the hardness is 8.0H. However, it is not very good in terms of overall blue light and hardness, but the hardness is still low, and it is not good for blue light. The cutoff rate is not very good either

Abstract

The invention relates to a super-hard blue light prevention display panel, belonging to the technical field of surface treatment of electronic product display panel. In order to solve the problem thatthe existing panel can not have both high hardness and blue light resistance, a super-hard blue light prevention display panel is provided and includes a transparent display substrate, an AR film capable of preventing blue light is plated on the surface of the transparent display substrate, the AR film is formed by alternatively, repeatedly and orderly stacking and plating Ti3O5 coating layers and Al2O3 doped SiO2 coating layers, the coating layer of the AR film contacted with the transparent display substrate is the Ti3O5 coating layer, and the doped amount of Al2O3 in the Al2O3 doped SiO2 coating is 1.0 wt%-15wt%. The invention can effectively realize the effect of both super-high hardness and anti-harmful blue light, so that the hardness can reach over 40N, and the cut-off rate of harmful blue light with short wave wavelength of 415nm-455nm is over 35%.

Description

technical field [0001] The invention relates to a superhard anti-blue light display panel, which belongs to the technical field of surface treatment of display panels of electronic products. Background technique [0002] With the development and increasing popularity of electronic products such as mobile phones, tablet computers, digital products and mobile electronic devices, the frequency of use in daily life has increased significantly. As we all know, blue light is more harmful to the body than light of other wavelengths. Short-wave blue light has extremely high energy and can penetrate the lens directly to the retina, causing light damage to the retina, directly or indirectly causing damage to cells in the macular area, and seriously endangering us. Eyes are healthy, and blue light not only exists in the sun, but also produces blue light when using electronic products such as mobile phones and tablet computers that we often use in our daily life. The blue light can tran...
