Description

Technical Field

[0001] The invention relates to a mobile phone, in particular to a mobile phone with a curved screen. Background Art

[0002] A mobile phone generally has a plate shape, and its display screen is mainly located on the front. In order to prevent the fragile display screen from being damaged, the outer side of the display screen is generally covered with a glass protective lens. The protective lens is generally first bonded to the display screen through a transparent adhesive layer to form a screen without gaps or air layer reflections, and then the whole is glued and installed on the mobile phone through the adhesive layer.

[0003] With the emergence of flexible displays (such as flexible OLED), some people make the protective lens into a curved shape, and the flexible display is bonded to the inside of the protective lens through a transparent adhesive layer to form a low-reflection curved screen along with the bending of the protective lens. Recently, the degree of curvature of this screen has been continuously improved, such as the "waterfall screen" where the screen is almost vertically curved to the side of the mobile phone, and even the "surround screen" that is curved to the back of the mobile phone.

[0004] The increased curvature of the mobile phone screen makes it difficult for users to attach a protective film on it, especially a more wear-resistant hard glass film. During the use of the mobile phone, the outermost protective lens is easily damaged (such as scratches and cracks) in the absence of a protective film, and because the flexible display is completely glued to the inside of the protective lens, once the protective lens is damaged and needs to be replaced, the expensive flexible display needs to be replaced as well, so the replacement cost is very high. In addition, due to the large curvature of the screen, it is very difficult to re-paste and install it on the mobile phone. After replacement, it is often difficult to ensure the tightness of the joint, and a large seam will appear, so the replacement effect is generally not ideal. Summary of the invention

[0005] The purpose of the present invention is to provide a mobile phone with a curved screen, the replacement cost of the screen protection lens of which is low and the operation is simple. The technical solution adopted is as follows:

[0006] A mobile phone with a curved screen, characterized by:

[0007] The mobile phone comprises a mobile phone body and a protective lens, wherein the mobile phone body has a plate shape and is provided with a display screen, wherein the display screen is at least bent from the front of the mobile phone body and extends to the side thereof;

[0008] The protective lens is made of glass and has a cylindrical shape. It is sleeved on the mobile phone body, not only covering the front of the mobile phone body, but also bending from the side of the mobile phone body to the back of the mobile phone body to cover the side and at least part of the back of the mobile phone body, and forming a mutual limitation between it and the mobile phone body, so that the protective lens and the mobile phone body form a drawer mechanism;

[0009] The protective lens comprises a transparent area, the transparent area corresponds to the display screen, at least a polarizer is pasted on the inner side of the transparent area, the polarizer at least corresponds to the display screen, and there is a gap or air layer between the polarizer and the mobile phone body;

[0010] The polarizer is a circular polarizer, which is used to reduce or eliminate the reflected light from the gap or air layer.

[0011] Specifically, in addition to the display screen, the mobile phone body may also include components such as a motherboard and a battery required for the mobile phone. Preferably, the mobile phone body includes the main support structure of the mobile phone, such as a rigid frame. The display screen may be a flexible display screen such as a flexible OLED, a flexible QLED, a flexible micro LED, etc. Generally speaking, the mobile phone body provides support for the display screen, and the display screen is attached to the mobile phone body through a certain adhesive layer, thereby forming a curved shape extending from at least the front of the mobile phone body to the side - preferably, the display screen further extends to the back of the mobile phone body. The display screen may include a certain touch sensing layer, especially a touch sensing layer based on the principle of capacitance, so that the finger can also manipulate the display screen through a protective lens, a polarizer and a gap (or an air layer).

[0012] Preferably, the thickness of the protective lens is 0.2 mm to 1.5 mm. Generally speaking, the outer dimensions of the protective lens can be designed according to the main body of the mobile phone so that it can be tightly mounted on the main body of the mobile phone - or in other words, the gap or air layer between it and the main body of the mobile phone is extremely thin (preferably less than 100 μm in thickness). The protective lens can be a fully enclosed cylindrical structure to wrap the front, side and back of the mobile phone without leaving any gaps. Preferably, the protective lens can also be formed by hot bending a glass substrate, so that the protective lens can leave a certain gap or a blank area running through the top and bottom on the back of the mobile phone. When the protective lens is transparent everywhere, its transparent area can be considered as the various areas of the protective lens; a certain masking layer can also be set on the inner side of the protective lens, such as a masking layer printed with black ink, to cover some peripheral areas. In this case, the transparent area is generally an area not blocked by the masking layer.

[0013] The polarizer is attached to the inner side of the protective lens, that is, at least in the transparent area, there is no gap or air layer between it and the protective lens. The polarizer is a circular polarizer, that is, it includes a polarization absorption layer and a λ / 4 delay layer from the outside to the inside (based on the mobile phone), and the optical axis of the λ / 4 delay layer is 45° with the polarization axis of the polarizing layer. Therefore, when external light irradiates the transparent area of ​​the protective lens, it passes through the polarizer and becomes circularly polarized light of a first rotation direction (such as left rotation). After the circularly polarized light is reflected on the two interfaces of the gap or air layer, it becomes circularly polarized light of a second rotation direction (such as right rotation). The second rotation direction is opposite to the second rotation direction, so the circularly polarized light will be absorbed when it passes through the polarizer again, thereby eliminating the reflected light of the gap or air layer and reducing the influence of its reflected light on the display and the appearance of the mobile phone.

[0014] In the above structure, the protective lens utilizes its own cylindrical structure to limit the mobile phone body to form a drawer mechanism, thereby further limiting the up and down movement of the protective lens, so that it can be fixed to the mobile phone body. Preferably, the mobile phone also includes an upper end and / or a lower end, and the upper end and the lower end are respectively fixed to the upper end and the lower end of the mobile phone body, and support the upper end and the lower end of the protective lens. Specifically, the upper end and the lower end can be cover bodies respectively arranged at the upper end and the lower end of the mobile phone, and the edges thereof protrude outward from the mobile phone body to support the protective lens. In order to fix the protective lens more stably, it is preferred that the upper end and / or the lower end are also provided with a fitting edge, which is tightly attached to the inner edge of the protective lens. In order to facilitate disassembly, the upper end and / or the lower end are fixed to the mobile phone body by a detachable connector, such as a screw fixing or a snap fitting. In order to realize more mobile phone functions, it is also preferred that the upper end and / or the lower end is provided with an earpiece, a microphone, a charging port, a camera and / or a mechanical button, and an electrical interface for electrical signal and / or power transmission is also provided between the upper end and / or the lower end and the mobile phone body, and the electrical interface is electrically connected while the upper end and / or the lower end is fixed to the mobile phone.

[0015] In addition, for the case where the protective lens leaves a blank area on the back of the mobile phone, it is preferred that the mobile phone also includes a back module, the back module is fixed and protrudes from the back of the mobile phone body, and the blank area of ​​the protective lens is sleeved on the back module, so that the movement of the protective lens is further limited by the back module. Specifically, when the blank area runs through the top and bottom, the back module can be a convex strip running through the back of the mobile phone, and when the blank area does not run through the top and bottom, the back module can also be a convex block on the back of the mobile phone. For the convenience of disassembly, the back module can also be fixed to the mobile phone body by a detachable connector, such as screws and buckles. In order to realize more mobile phone functions, it is also preferred that the back module is provided with a camera, a flash, a fingerprint reader and / or a mechanical button, and an electrical interface for electrical signal and / or power transmission is also provided between it and the mobile phone body, and the electrical interface is electrically connected while the back module and the mobile phone are fixed to each other.

[0016] Compared with the technical solution of the present invention, the mobile phone with a curved screen provided by the present invention has the following beneficial effects:

[0017] The display screen of the mobile phone is arranged on the main body of the mobile phone, and the protective lens is designed to be in the shape of a cylinder that is sleeved outside the main body of the mobile phone. A circular polarizer is attached to the inner side of the protective lens so that it does not need to be attached to the display screen by a transparent adhesive layer. Finally, the protective lens can form a movement restriction with the main body of the mobile phone by relying on its own cylindrical shape, that is, the protective lens and the main body of the mobile phone form a drawer mechanism. When installing or disassembling, the protective lens can be inserted into or pulled out of the main body of the mobile phone, and it is only necessary to further restrict the upward and downward movement of the protective lens at the upper and lower ends or the back side to form a mutual fixation with the main body of the mobile phone. Therefore, when the protective lens is damaged and needs to be replaced, it is only necessary to simply release the restriction on the upward and downward movement of the protective lens, pull out the damaged protective lens, and insert the new protective lens into the main body of the mobile phone. The operation is very simple. Since only a very low-priced polarizer is attached to the inner side of the protective lens, it is not necessary to replace the expensive flexible display screen when replacing it, so the replacement cost is very low.

[0028] Embodiment 1

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the mobile phone 100 includes a mobile phone body 10, a protective lens 20, an upper end 30 and a lower end 40. The mobile phone body 10 is a plate structure provided with an aluminum alloy rigid frame (not shown in the figure), and an OLED flexible display screen 11 with an embedded capacitive touch is adhered to its surface. The display screen 11 is bent from the front of the mobile phone body 10 and extends to its side to form a "waterfall screen" design.

[0030] The protective lens 20 is transparent as a whole (the whole is a transparent area), and is made of 0.4 mm (0.2 mm to 1.5 mm) glass. It has a cylindrical shape that is closely attached to the mobile phone body 10. It is sleeved on the mobile phone body 10, not only covering the front of the mobile phone body 10, but also bending from the side of the mobile phone body 10 to the back of the mobile phone body 10 to completely cover the back of the mobile phone body 10 and form a mutual limitation between it and the mobile phone body 10. The protective lens 20 and the mobile phone body 10 form a drawer mechanism;

[0031] A circular polarizer 21 is adhered to the inner side of the protective lens 20 via a transparent adhesive layer 211 , and a gap or air layer 22 with a thickness of less than 100 μm exists between the protective lens 20 and the mobile phone body 10 .

[0032] like Figure 3As shown, the polarizer 21 includes a polarizing absorption layer 212 and a λ / 4 delay layer 213 from the outside to the inside, and the optical axis of the λ / 4 delay layer 213 is 45° with the polarizing axis of the polarizing absorption layer 212. When the external light L1 is irradiated onto the protective lens 20, it passes through the polarizer 21 and becomes left-handed circularly polarized light L2. After the left-handed circularly polarized light L2 is reflected on the two interfaces of the gap or air layer 22, it becomes right-handed circularly polarized light L3. The right-handed circularly polarized light L3 will be absorbed when passing through the polarizer 21 again, thereby eliminating the reflected light of the gap or air layer 22 and reducing the influence of the reflected light on the display.

[0033] The upper end 30 and the lower end 40 are covers fixed to the upper and lower ends of the mobile phone body 10 by screws (not shown in the figure), and the edges 301 and 401 thereof protrude outward from the mobile phone body 10 to support the protective lens 20. At the same time, the inner side thereof is also provided with fitting edges 302 and 402 to fit tightly with the inner edge of the protective lens 20. The upper end 30 is provided with a receiver 31, a camera 32 and a mechanical switch button 33, and the lower end 40 is provided with a microphone 41 and a charging port (not shown in the figure). Electrical interfaces 34 and 43 for transmitting electrical signals and / or power are provided between the upper and lower ends 30 and 40 and the mobile phone body 10, which realize electrical connection when the upper and lower ends 30 and 40 are fixed to each other.

[0034] When replacing the protective lens 20 of the mobile phone, the upper and lower ends 30 and 40 can be removed first, and the old protective lens 20 can be pulled out, and then Figure 4 , Figure 5 As shown in steps 1 and 2, the new protective lens 20 is put on the mobile phone body 10, and then the upper and lower ends 30 and 40 are installed again. The operation is very simple. Moreover, since only the polarizing film 21, which is very cheap, is attached to the inner side of the protective lens 20, it is not necessary to replace the expensive flexible display screen 11 when replacing it, so the replacement cost is very low.

[0035] like Figure 6 As shown, in another scheme of the present embodiment, a masking layer 23 is further provided on the inner side of the protective lens 20 by means of black ink, black photosensitive resin, black film or black metal coating. The masking layer 23 is provided in the peripheral area of ​​the protective lens 20 to shield the non-display area and the edge of the polarizer 21, while the transparent area of ​​the protective lens is the area not shielded by the masking layer 23.

[0036] like Figure 7As shown, in another scheme of the present embodiment, the display screen 11 is further extended to the back of the mobile phone body 10 to form a "surround screen" design. The protective lens 20 is also provided with a non-vertically-through-through blank area 24 on the back of the mobile phone 100, and the mobile phone 100 is also provided with a back module 50, which is fixed by screws 501 (easy to disassemble, not shown in the figure) and protrudes from the back of the mobile phone body 10. The protective lens 20 is sleeved on the back module 50 with its blank area 24, so that the movement of the protective lens 20 is further limited by the back module 50. The back module 50 is provided with a camera 51 and a flash 52, and an electrical interface for electrical signal transmission is also provided between it and the mobile phone body 10 (not shown in the figure), and the electrical interface 53 realizes electrical connection when the back module 50 and the mobile phone body 10 are fixed to each other.

[0037] Embodiment 2

[0038] like Figure 8 , Fig. 9 As shown, on the basis of the first embodiment, the protective lens 20 is changed to leave a blank area 25 running through the back of the mobile phone 100 from top to bottom, which constitutes the second embodiment of the present invention. Among them, the protective lens 20 is made of a flat glass substrate through hot bending. The mobile phone 100 is also provided with a back module 60, which is fixed by screws 601 (easy to disassemble) and protrudes from the back of the mobile phone body 10. The blank area 24 of the protective lens 20 is stuck on the back module 60, so that the movement of the protective lens 20 is further limited by the back module 60. The back module 60 is provided with a camera 61, a flash 62 and a fingerprint identifier 63, and an electrical interface 64 for electrical signal transmission is also provided between it and the mobile phone body 10. The electrical interface 64 realizes electrical connection while the back module 60 and the mobile phone body 10 are fixed to each other.

[0039] In addition, it should be noted that the names of the various parts of the specific embodiments described in this specification may be different, and any equivalent or simple changes made based on the structure, features and principles described in the patent concept of the present invention are included in the protection scope of the patent of the present invention.
