Description

Display device

Technical Field

The invention relates to the technical field of display, in particular to a display device.

Background

With the continuous development of electronic devices such as mobile phones and tablet computers, the requirements of users on the electronic devices are higher and higher, wherein the screen ratio is an important parameter of the mobile terminal.

In order to improve the screen occupation ratio in the movement, the Liuhai screen, the water drop screen, the hollowed screen and the like are successively published, wherein the screen occupation ratio of the hollowed screen is the highest. Currently, LCD (Liquid Crystal Display) screens and OLED (Organic Light-Emitting Diode) screens can be used as the hollow screens. The hole digging screen can be divided into a through hole screen and a blind hole screen according to different hole digging modes. Compared with an LCD blind hole screen, the OLED through hole screen has higher transmittance and excellent image effect.

Because the terminal brand continuously promotes the requirements on the proportion of the mobile phone screen, the position of the front camera is changed from a Liuhai type, a water drop type and a pop-up type to the latest punching screen, and the mobile phone screen is subjected to various changes.

The perforated screen is a circular hole formed in a display area of the mobile phone and used for arranging a camera, so that the screen occupation ratio is further improved. From the technical point of classification, the punching can be divided into two schemes of blind holes and through holes.

At present, the effect of shading the through hole by the punching screen is not good, so that the yield is not high. Therefore, a new solution is needed to solve the problem of poor light-shielding effect at the through hole.

According to an aspect of the present invention, an embodiment of the present invention provides a display device, including: a display panel having a light-transmitting region; the functional layer is arranged on one surface of the display panel and is provided with a first opening, and the first opening corresponds to the light-transmitting area; a functional device accommodated in the first opening; and the sealing element is arranged between one side wall of the functional layer at the position of the first opening and the peripheral surface of the functional device, and is used for shading light leakage at the periphery of the first opening and preventing the functional device from impacting the display panel.

Further, a polarizer is arranged on at least one of the surface of the display panel close to the functional layer and the surface of the display panel far away from the functional layer, and the polarizer is provided with a second opening corresponding to the light transmitting area.

Further, the seal includes: the first sealing part is arranged on the side wall of the functional layer at the position of the first opening; the second sealing part is arranged on one surface of the functional layer, which is far away from the display panel.

Further, at least one of the first sealing part and the second sealing part is fixedly connected with the functional layer in an attaching mode.

Further the display device further comprises: and the third opening is arranged on the display panel and corresponds to the light-transmitting area, and the third opening is communicated with the second opening.

Further, the sealing member is a detachable sealing member.

Further, the sealing member is made of non-transparent rubber.

Further, the rubber is a thermoplastic rubber.

Furthermore, the display device further comprises a light shielding member, and the light shielding member is arranged on one surface of the functional layer close to the display panel and close to the first opening.

Further, the functional part is convex, the bulge of the functional part is arranged in the first opening, and two ends of the bottom of the functional part are used for bearing the sealing element.

The sealing element has the advantages that the sealing element is easy to mount and dismount and has heavy workability. The seal is made of a non-transparent, resilient polymer (e.g., rubber). Because the whole chain of the elastic polymer cannot move, and the chain segment can move, the elastic polymer can be greatly deformed by external force, but can be restored after the force disappears, and therefore the sealing element has certain buffering property. Because the sealing member possesses certain cushioning nature, consequently can reserve less clearance between functional device (for example the module of making a video recording) and sealing member to reduce the aperture of trompil, promote the screen and account for the ratio. In addition, the sealing member can provide the cushion force to avoid making a video recording the module striking display panel.

An embodiment of the present invention provides a display device, including: a display panel having a light-transmitting region; the functional layer is arranged on one surface of the display panel and is provided with a first opening, and the first opening corresponds to the light-transmitting area; a functional device accommodated in the first opening; and the sealing element is arranged between one side wall of the functional layer at the position of the first opening and the peripheral surface of the functional device, and is used for shading light leakage at the periphery of the first opening and preventing the functional device from impacting the display panel.

Further, the display device further includes: and the third opening is arranged on the display panel and corresponds to the light-transmitting area, and the third opening is communicated with the second opening.

As shown in fig. 1, a display device is provided according to a first embodiment of the present invention. The display device includes: the device comprises a functional layer 8, a first polaroid 6, a first opening 16, a sealing piece 9, a shading adhesive tape 7, a first glass 5, a second glass 4, a second polaroid 3, a functional device 10, a light-transmitting area 20, an optical adhesive layer 2, two second openings 15 and a glass cover plate 1.

In one embodiment of the present invention, the display panel 18 includes: a glass cover plate 1, a first polarizer 6, a first glass 5, a second glass 4, a light-transmitting area 20, a second polarizer 3 and an optical adhesive layer 2. The functional layer 8 is a backlight module. The functional device 10 is mainly a camera module. The polarizer includes: a first polarizer 6 and a second polarizer 3.

Wherein the position of the light-transmitting area 20 corresponds to the position where the functional device 10 is disposed. The light-transmitting region is a part of the first glass 5, the second glass 4, the first polarizer 6, and the second polarizer 3. Wherein the first polarizer 6 and the second polarizer 3 have an open-pore (second open pore 15) structure. The first glass 5 and the second glass 4 are transparent, so that the first glass and the second glass together form a light-transmitting region 20. The projected area of the light-transmitting region 20 perpendicular to the horizontal plane should be not less than the projected area of the first opening 16 perpendicular to the horizontal plane.

The first polarizer 6 is arranged above the backlight module. The first opening 16 penetrates through the backlight module. The second opening is formed in the first polarizing plate 6 and the second polarizing plate 3. The seal 9 is disposed between a side wall of the functional layer 8 at the location of the first opening 16 and the outer circumferential surface of the functional device 10. The sealing member 9 is used for shielding light leakage around the first opening 16 and preventing the functional device 9 from impacting the display panel 18.

With combined reference to fig. 4, the seal 9 comprises: a first seal portion 14 and a second seal portion 13. The first sealing portion 17 is disposed on the side wall of the functional layer 8 at the position of the first opening 16. The second sealing portion 13 is disposed on a surface of the functional layer 8 away from the display panel 18. The length of the first seal 14 is generally equal to the height of the first aperture 16. But is not limited thereto, the length of the first sealing portion 14 may be adjusted as needed in an actual production process. For example, the length of the first sealing portion 14 is greater than the height of the first opening 16, or the length of the first sealing portion 14 is less than the height of the first opening 16. Therefore, in the first embodiment, the first sealing portion 14 of the sealing member 9 can block not only the light leakage around the first opening, but also the light leakage around the second opening.

The light shielding device using the sealing member 9 as the opening has advantages in that the sealing member is easily mounted and dismounted, and has heavy workability. The seal is made of a non-transparent, resilient polymer (e.g., rubber). Because the whole chain of the elastic polymer cannot move, and the chain segment can move, the elastic polymer can be greatly deformed by external force, but can be restored after the force disappears, and therefore the sealing element has certain buffering property. Because sealing member 9 possesses certain resiliency, consequently, can reserve less clearance between module 10 and sealing member 9 of making a video recording to reduce the aperture of first trompil 16 and second trompil 15, promote the screen and account for the ratio.

The sealing member is a detachable sealing member. The material of the sealing member 9 is a non-transparent rubber material. The non-transparent rubber material may be thermoplastic rubber, but is not limited thereto, and may be other materials having elasticity in other embodiments.

In the first embodiment of the present invention, the second polarizer 3, the second glass 4, the first glass 5 and the first polarizer 6 constitute a glass layer of the display panel 18. The glass layer of the display panel 18 and the backlight module are bonded and combined through the shading tape 7 to form the display module. The display module is attached to the glass cover plate 1 through the optical adhesive layer 2, and finally a full-attachment display module is formed.

The sealing element has the advantages that the sealing element is easy to mount and dismount and has heavy workability. The seal is made of a non-transparent, resilient polymer (e.g., rubber). Because the whole chain of the elastic polymer cannot move, and the chain segment can move, the elastic polymer can be greatly deformed by external force, but the elastic polymer can be restored to the original shape after the external force disappears, so that the sealing element has certain buffering property. Because the sealing member possesses certain cushioning nature, consequently can reserve less clearance between functional device (for example the module of making a video recording) and sealing member to reduce the aperture of trompil, promote the screen and account for the ratio. In addition, the sealing member can provide the cushion force to avoid making a video recording the module striking display panel.

For example, the length of the first sealing portion 14 is greater than the height of the first opening 16, or the length of the first sealing portion 14 is less than the height of the first opening 16. Therefore, in the second embodiment, the first sealing portion 14 of the sealing member 9 can block not only the light leakage around the first opening and the second opening, but also the light leakage around the third opening.

The light shielding device using the sealing member 9 as the opening has advantages in that the sealing member is easily mounted and dismounted, and has heavy workability.
