Description

High transmission anti-peeping mobile phone screen glass plate

technical field

The utility model relates to a high-transmission anti-peeping mobile phone screen glass plate.

Background technique

At present, with the powerful functions of mobile phones, mobile phones have become the necessary daily necessities that people carry with them. People often use mobile phones in buses, subways or other public places. In this case, the user of the mobile phone often does not want others around to see the content displayed on the screen of his mobile phone. Mobile phones in the prior art have a larger viewing angle range, usually 70 degrees, so that even at a position far away from the front of the display screen, the content on the display screen can still be seen relatively clearly, which is not conducive to protecting the privacy of users . In addition, since the glass plate generally needs better waterproof and drop resistance, it is also the direction of people's research.

Utility model content

The purpose of the utility model is to overcome the above-mentioned shortcomings, and provide a high-transmission anti-peeping mobile phone screen glass plate.

In order to achieve the above object, the specific scheme of the utility model is as follows: a high-transmission anti-peep mobile phone screen glass plate, including a glass substrate, positioning grooves are provided on the four sides of the glass substrate, and the positioning grooves are Multiple arc-shaped slots.

Wherein, the free ends of the connecting parts between the two positioning grooves are arc-shaped.

Wherein, a groove is arranged near the edge of the glass substrate, and a sealing ring is arranged in the groove.

Wherein, the glass substrate includes a glass plate, the top surface of the glass plate is provided with a high-refractive index medium layer, the top surface of the high-refractive index medium layer is provided with a low-refractive-index medium layer, and the top surface of the low-refractive-index medium layer is The surface is provided with protruding ribs with a micro-louver structure, and the angle between the two sides of the protruding ribs and the low-refractive index medium layer is 45 degrees.

Wherein, the bottom surface of the glass plate body is also provided with an anti-electromagnetic interference layer; the thickness of the anti-electromagnetic interference layer is 0.25 mm.

The beneficial effect of the utility model is that the positioning groove can conveniently and accurately position the glass plate body and the frame of the mobile phone. The anti-peep function can prevent others from peeking at the contents of your mobile phone.

detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the scope of implementation of the utility model is not limited thereto.

As shown in Figures 1 to 3, a high-transmission anti-peeping mobile phone screen glass plate described in this embodiment; a high-transmission anti-peeping mobile phone screen glass plate includes a glass substrate 1, and four of the glass substrate 1 Positioning grooves 3 are arranged on each side, and the positioning grooves 3 are a plurality of arc-shaped grooves. The positioning groove 3 can accurately position the glass plate body 4 and the frame of the mobile phone conveniently. Generally, serrated positioning protrusions corresponding to the positioning grooves 3 are also provided on the frame or the PCB board.

In the high-transmission anti-peeping mobile phone screen glass plate described in this embodiment, the free end of the connecting part between the two positioning grooves 3 is arc-shaped. Prevent excessive sharpness from damaging the glass.

In the high-transmission anti-peeping mobile phone screen glass plate described in this embodiment, a groove 2 is provided near the edge of the glass substrate 1, and a sealing ring 5 is provided in the groove 2. Increased drop resistance. A high-transmission anti-peep mobile phone screen glass plate described in this embodiment, the glass substrate 1 includes a glass plate body 4, the top surface of the glass plate body 4 is provided with a high-refractive index medium layer 8, and the high-refractive index medium The top surface of the layer 8 is provided with a low-refractive-index medium layer 6; the material of the high-refractive-index medium layer 8 is trititanium pentoxide. The material of the low refractive index medium layer 6 is silicon dioxide. The main function of these two layers of film "high refractive index medium layer 8; low refractive index medium layer 6" is to reduce the reflection of visible light and increase the transmission. The top surface of the low refractive index medium layer 6 is provided with micro-louver structure ribs 7 , and the angle between the two sides of the ribs 7 and the low refractive index medium layer 6 is 45 degrees. In this way, the viewing angle range of the mobile phone display is reduced to 45 degrees. After testing, it is found that when the viewing angle is 30 degrees, the content displayed on the display screen cannot be clearly viewed. The bottom surface of the glass plate body 4 is also provided with an anti-electromagnetic interference layer; the thickness of the anti-electromagnetic interference layer is 0.25 mm. The anti-electromagnetic interference layer can be made of PEC material, which is anti-reflection, anti-electromagnetic radiation, effectively filters ultraviolet rays, and can make the picture of the display screen more clear and vivid.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the utility model patent application are included in the protection of the utility model patent application. within range.
