Description

Technical Field

[0001] This utility model relates to the field of touch screens, specifically to an ultra-narrow bezel touch screen. Background Technology

[0002] The working principle of an in-cell ultra-narrow bezel touchpad is to embed the touch panel function into the liquid crystal pixels to achieve touch sensing. Specifically, the in-cell touchpad works by utilizing the electric current sensing of the human body. When a finger touches the metal layer, due to the human body's electric field, a coupling capacitor is formed on the surface of the touch layer. For high-frequency currents, the capacitor is a direct conductor, which affects the overall capacitance characteristics. The touch chip determines the finger's position and operation by detecting changes in capacitance. In-cell touchpads typically use mutual capacitance technology, which divides the touch panel into horizontal and vertical electrode arrays. When a finger touches, it affects the coupling between two electrodes near the touch point, thereby changing the capacitance between these two electrodes. The touch chip determines the finger's position and operation by detecting these changes in capacitance. The advantages of the in-cell ultra-narrow bezel touchpad are that it allows for a narrower bezel design, increasing the screen-to-body ratio, while also improving touch sensitivity and accuracy. When using an ultra-narrow bezel touchpad, the protective glass on the front of the touchpad is easily scratched by sharp objects, such as fingernails. Scratches can damage the flatness and smoothness of the screen, causing uneven reflection or abnormal refraction at the scratched area under certain lighting conditions, affecting the clarity and visual effect of the screen display content, especially when displaying white or light-colored backgrounds. Utility Model Content

[0003] The purpose of this utility model is to provide an ultra-narrow bezel touch screen to solve the problem mentioned in the background art that the protective glass on the front of the touch panel is easily scratched by sharp objects during use, and the scratches will damage the flatness and smoothness of the screen.

[0004] To achieve the above objectives, an ultra-narrow bezel touchscreen is provided, comprising a screen panel, a narrow frame fixedly installed on the outer side of the screen panel, and a protective glass covering the surface of the screen panel. A buffer strip is fixedly installed at the end of the protective glass surface, and a positioning frame is provided at the corner of the protective glass. A mounting area is opened at the bottom of the protective glass, and the mounting area is adapted to the size of the narrow frame. The narrow frame is mounted inside the mounting area, and a protective film is adhered and fixed to the surface of the protective glass. Four sets of receiving openings are evenly opened on the outer side of the protective film. Assembly seats are fixedly installed on both sides of the narrow frame, and splicing grooves are opened on the inner wall surface of the mounting area.

[0005] Preferably, the thickness of the narrow frame is equal to the depth of the mounting area, and the narrow frame is fixed inside the mounting area and evenly fixed by four sets of fixing bolts.

[0006] Preferably, the dimensions of the assembly base and the splicing groove are compatible, and the assembly base is fixedly snapped into the inside of the splicing groove. Both the assembly base and the splicing groove are dovetail-shaped structures.

[0007] Preferably, the bottom of the splicing groove is provided with a screw hole, and the assembly base is provided with a through hole. The cross-section of the through hole is set in a "T" shape, and the screw hole is adapted to the size of the fixing bolt. The fixing bolt passes through the through hole and is screwed and fixed inside the screw hole.

[0008] Preferably, two sets of positioning frames are arranged opposite each other on the surface of the protective glass, and the positioning frames are arranged in an "L" shape. At the same time, the protective film is attached to the surface of the protective glass and is limited by the two sets of positioning frames.

[0009] Preferably, the protective glass has notches at a set of corners, and the notches are fan-shaped, with the end of the protective film covering the surface of the notches.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model covers the surface of protective glass with a protective film. The protective film can protect the protective glass and prevent scratches from forming on the surface of the protective glass. At the same time, it can prevent uneven reflection or abnormal refraction at the scratches, which would affect the clarity and visual effect of the screen display content. The end of the protective film covers the surface of the notch. The notch can be used to quickly peel off the protective film from the surface of the protective glass. 2. This utility model, by designing the buffer strips in a straight line and setting four sets of buffer strips, can effectively reduce the impact force generated when the touch screen is accidentally bumped or dropped, reducing the risk of the touch screen breaking. When the device accidentally slips off the table and hits the ground, the anti-collision buffer strips can absorb some of the impact energy; at the same time, it provides extra protection for the ultra-narrow bezel design, making up for the lack of protection that the narrow bezel may bring; when the touch screen comes into contact with other objects, it prevents the edge of the protective glass from directly rubbing against it, thereby reducing wear.

[0013] Please see Figure 1-5 This utility model provides an ultra-narrow bezel touch screen, including a screen panel 1, a narrow frame 2 fixedly installed on the outer side of the screen panel 1, and a protective glass 3 covering the surface of the screen panel 1. At the same time, a buffer strip 31 is fixedly provided at the end of the surface of the protective glass 3, and a positioning frame 32 is provided at the corner of the protective glass 3. A mounting area 36 is opened at the bottom of the protective glass 3, and the mounting area 36 is adapted to the size of the narrow frame 2. The narrow frame 2 is mounted inside the mounting area 36, ​​and a protective film 5 is adhered and fixed to the surface of the protective glass 3. Four sets of receiving openings 51 are evenly opened on the outer side of the protective film 5. A splicing seat 21 is fixedly provided on both sides of the narrow frame 2, and a splicing groove 34 is opened on the inner wall surface of the mounting area 36.

[0014] As can be seen from the above, when using the device, the operator first places the screen panel 1 and its outer narrow frame 2 inside the mounting area 36 at the bottom of the protective glass 3. At this time, the four sets of assembly seats 21 are respectively inserted into the four sets of splicing slots 34 evenly opened on the inner wall of the mounting area 36. In this way, the screen panel 1 is fixedly installed inside the protective glass 3. The protective glass 3 protects the screen panel 1 from damage caused by external impact. Then, the fixing bolts 4 are screwed through the through holes 22 and fixed inside the screw holes 35, thus completing the installation. The protective glass 3 and the screen panel 1 are fixedly installed to ensure their stability and prevent loosening. The surface of the protective glass 3 is covered with a protective film 5. The protective film 5 protects the protective glass 3, preventing scratches and uneven reflection or abnormal refraction at scratches, which could affect the clarity and visual effect of the screen display. The end of the protective film 5 covers the surface of the notch 33, allowing the protective film 5 to be quickly peeled off the surface of the protective glass 3. In a preferred embodiment, the thickness of the narrow frame 2 is equal to the depth of the mounting area 36, ​​and the narrow frame 2 is fixed inside the mounting area 36 and is evenly fixed by four sets of fixing bolts 4.

The through hole 22 has a "T" shaped cross section, and the screw hole 35 is adapted to the size of the fixing bolt 4. The fixing bolt 4 passes through the through hole 22 and is screwed and fixed inside the screw hole 35.

[0017] As can be seen from the above, during use, the two sets of positioning frames 32 facilitate the quick and accurate covering of the protective film 5 onto the surface of the protective glass 3. At the same time, four sets of buffer strips 31 are evenly installed on the outer surface of the protective glass 3. The buffer strips 31 are made of rubber and have a straight structure. The four sets of buffer strips 31 can effectively reduce the impact force generated when the touch screen is accidentally bumped or dropped, reducing the risk of the touch screen breaking.

This method secures the screen panel 1 inside the protective glass 3. The protective glass 3 protects the screen panel 1 from damage caused by external impacts. Then, the fixing bolts 4 are passed through the through holes 22 and screwed into the screw holes 35, thus completing the secure installation between the protective glass 3 and the screen panel 1 and ensuring stability after installation, preventing loosening. A protective film 5 covers the surface of the protective glass 3, protecting it from scratches and preventing uneven reflection at scratched areas. In case of abnormal refraction, the clarity and visual effect of the screen display content may be affected; the end of the protective film 5 covers the surface of the notch 33, and the protective film 5 can be quickly peeled off the surface of the protective glass 3 through the notch 33; the setting of two sets of positioning frames 32 makes it easy to quickly and accurately cover the surface of the protective glass 3 with the protective film 5. At the same time, four sets of buffer strips 31 are evenly installed on the outer side of the surface of the protective glass 3. The buffer strips 31 are made of rubber and have a straight structure. The setting of four sets of buffer strips 31 can effectively reduce the impact force generated when the touch screen is accidentally bumped or dropped, reducing the risk of the touch screen breaking. When the device accidentally slips from the table and hits the ground, the anti-collision buffer strips 31 can absorb some of the impact energy; at the same time, it provides additional protection for the ultra-narrow bezel design, making up for the lack of protection that the narrow bezel may bring; when the touch screen comes into contact with other objects, it prevents the edge of the protective glass from directly rubbing, thereby reducing wear.
