The display device provided by the embodiment of the invention comprises a backlight module 1, a display panel 2, an optical element 3 and a brightness compensation component 4, wherein the optical element 3 can be a camera or an infrared identification element, and the like, the brightness compensation component 4 has an expansion state and a contraction state, in the expansion state, the optical element 3 does not work, and the first light-emitting element 41 of the brightness compensation component 4 emits light towards the display panel 2 to provide light for an area of the display panel 2 corresponding to a first opening K, so that the brightness requirement of the display panel 2 is met, full-screen display is realized, and in the contraction state, the optical element 3 starts to work, so that the brightness compensation component 4 needs to be contracted at least partially in the first opening K to expose the optical element 3, and the first light-emitting element 41 of the contracted brightness compensation component 4 emits light towards the backlight module 1, so that the light-emitting brightness of the backlight module 1 is improved, and the display effect of the display panel 2 is further improved. The display device provided by the embodiment of the invention can realize normal display of the position of the display panel 2 corresponding to the first opening K, namely full-screen display, while ensuring that the optical element 3 can work normally through mutual conversion of the expansion state and the contraction state of the brightness compensation component 4.

Optionally, the optical element 3 in this embodiment may be a camera, when the camera is not needed to take a picture or photograph, the brightness compensation component 4 is in the expanded state, and the brightness compensation component 4 is located between the first opening K and the optical element 3, as shown in fig. 2, when the picture or the photograph is needed, the brightness compensation component 4 is converted from the expanded state to the contracted state, and at least part of the brightness compensation component 4 is contracted in the first opening K, so that the camera can be exposed, and external light is received, thereby meeting the requirements of taking a picture or photographing, as shown in fig. 3.

Backlight unit 1 sets up optical element 3 and brightness compensation subassembly 4 in the purpose that first trompil K was set up, and when needs were taken a picture or were made a video recording, the external light of being convenient for sees through display panel 2 and first trompil K and gets into optical element 3, satisfies optical element 3's light demand.

The backlight module 1 in this embodiment is used for providing light to the Display panel 2, so that the Display panel 2 can realize light emitting Display, and the description will be given by taking the Display panel 2 as an LCD (Liquid Crystal Display) panel as an example.

Optionally, the display panel 2 includes an array substrate 21 and a color filter substrate 22 that are stacked, a liquid crystal layer is further disposed between the array substrate 21 and the color filter substrate 22, the array substrate 21 includes components such as a thin film transistor, a pixel electrode, and a common electrode, and the color filter substrate 22 includes films such as a black matrix and a color resistor.

The light-emitting side of the display panel 2 may be further sequentially provided with films such as a polarizer 7, an optical adhesive layer 8, and a cover plate 9.

Referring to fig. 4 and 5, fig. 4 is a diagram illustrating a structure of a film layer at B in fig. 3 according to an embodiment of the present invention; fig. 5 is a top view of the brightness compensation assembly 4 according to an embodiment of the present invention. In some alternative embodiments, the brightness compensation assembly 4 includes at least two supporting plates 42, each supporting plate 42 is connected to a portion of the backlight module 1 located around the first opening K, and the first light-emitting device 41 is disposed on a side of the supporting plate 42 facing away from the optical device 3.

It should be noted that each supporting plate 42 also has an expanded state and a contracted state, the supporting plate 42 can move relative to the backlight module 1, specifically, the supporting plate 42 is arranged in an expanded state to make the side of the supporting plate 42 away from the optical element 3 face the display panel 2, so as to provide light irradiation for the display panel 2, and in the contracted state, the supporting plate 42 is contracted towards the inside of the first opening K, specifically, a part of the supporting plate 42 (for example, the part of each supporting plate 42 located in the first opening K) is bent towards the first opening K by 90 °, so that the first light emitting element 41 can face the backlight module 1. The support plate 42 may be made of a material having a certain bending property to allow the support plate 42 to complete the conversion between the expanded state and the contracted state, and for example, the support plate 42 may be made of polyimide, polystyrene, polyethylene terephthalate, parylene, polyethersulfone, or polyethylene naphthalate, or other resin materials, without particular limitation.

Optionally, the first light emitting element 41 and the supporting plate 42 may be adhered by an Adhesive, such as an Adhesive layer with a certain viscosity, for example, OCA (optical Clear Adhesive), an acrylic Adhesive material, or a silicone Adhesive, so as to ensure the stability of fixing the first light emitting element 41.

Of course, the switching between the expanded state and the contracted state of the supporting plates 42 can be realized in other forms, for example, each supporting plate 42 can be rotatably connected to the adjacent backlight module 1, and in the contracted state, each supporting plate 42 rotates towards the first opening K to adjust the light emitting direction of the first light emitting element 41.

Since the brightness compensation assembly 4 is required to be located between the first opening K and the optical element 3 in the expanded state, the first light emitting element 41 is used to provide a light source for the display panel 2 corresponding to the area of the first opening K, and the brightness compensation assembly 4 is required to be at least partially retracted in the first opening K in the retracted state, in order to achieve the above arrangement, as shown in fig. 5, in some alternative embodiments, the orthographic shape of the brightness compensation assembly 4 on the display panel 2 is matched with the orthographic shape of the first opening K on the display panel 2.

In this embodiment, since the first opening K is usually disposed to correspondingly dispose the optical element 3, for example, when the orthographic projection of the optical element 3 on the display panel 2 is circular, the orthographic projection of the first opening K and the brightness compensation module 4 on the display panel 2 is also correspondingly circular, specifically, since the brightness compensation module 4 mainly comprises the supporting plate 42 and the first light-emitting element 41, and the first light-emitting element 41 is relatively small and located on the supporting plate 42, the orthographic projection shape of the brightness compensation module 4 on the display panel 2 is mainly determined by the supporting plate 42, when the orthographic projection of the first opening K on the display panel 2 is circular, the orthographic projection of the structure formed by mutually splicing the supporting plates 42 on the display panel 2 is circular, and the radius of the circular orthographic projection of each supporting plate 42 is greater than the radius of the circular orthographic projection of the first opening K, so that the supporting plate 42 is connected with the backlight module 1. Of course, the orthographic projection of the first opening K, the brightness compensation element 4 and the optical element 3 on the display panel 2 may be square, and the shape is not limited.

Referring to fig. 5 and 6, fig. 6 is a top view of a brightness compensation assembly 4 according to another embodiment of the present invention. In some alternative embodiments, the orthographic shape of the brightness compensation assembly 4 on the display panel 2 and the orthographic shape of the first opening K on the display panel 2 are both circular, and the brightness compensation assembly 4 includes at least four fan-shaped support plates 42.

It can be understood that the larger the number of the support plates 42 included in the brightness compensation assembly 4, the smaller the size of the individual support plates 42, and the smaller the bending stress applied during bending, and the easier it is to bend the first opening K in the contracted state. Alternatively, the supporting plates 42 may be symmetrically distributed about the center of the first opening K, and an orthographic projection of the circle formed by the supporting plates 42 on the display panel 2 and an orthographic projection of the first opening K on the display panel 2 are concentric to facilitate the expansion and contraction of the supporting plates 42.

Alternatively, the central angles of the fan-shaped support plates 42 are all equal. For example, the brightness compensation assembly 4 includes four fan-shaped supporting plates 42, the central angle of each fan-shaped supporting plate 42 is 90 °, and the first light emitting elements 41 are respectively disposed on each supporting plate 42, so as to ensure the uniformity of the light emitted from the first light emitting elements 41 on the supporting plates 42, the first light emitting elements 41 can be uniformly distributed on the supporting plates 42, so that the light emitted from the first light emitting elements 41 can be uniformly irradiated to the display panel 2 or the backlight module 1.

Of course, the brightness compensation assembly 4 may also include other numbers of support plates 42, such as 6 or 8, correspondingly, when there are 6 support plates 42, the central angle of each support plate 42 is 60 °, and when there are 8 support plates 42, the central angle of each support plate 42 is 45 °, it should be noted that the number of the support plates 42 is not too large, which would result in too small a support plate 42, and it is not convenient to arrange the first light-emitting element 41 on the support plate 42.

Referring to fig. 5 and 6, in order to further improve the uniformity of the light emitted from the first light emitting elements 41, in some alternative embodiments, the first light emitting elements 41 are uniformly distributed on the supporting plate 42 in a ring shape with respect to the center of the brightness compensation assembly 4.

In this embodiment, one or more circles of the first Light Emitting elements 41 may be specifically arranged according to different Light irradiation ranges of the first Light Emitting elements 41, one circle of the first Light Emitting elements 41 is arranged in fig. 5, and two circles of the first Light Emitting elements 41 are arranged in fig. 6, as long as the first Light Emitting elements 41 can meet the Light source requirement of the display panel 2 corresponding to the first opening K region, and the first Light Emitting elements 41 may be specifically Micro LEDs (Micro Light Emitting diodes) or Mini-LEDs (small Light Emitting diodes). The Micro LED and the Mini-LED have the advantages of small size, high luminous efficiency, low energy consumption and the like, the size of the Micro LED is smaller than 50 mu m, and the size of the Mini-LED is smaller than 100 mu m.

Considering that the first light emitting element 41 needs to be disposed on the support plate 42, the disposition space is limited, and thus the first light emitting element 41 in this embodiment may specifically employ a Micro LED with a smaller size for the convenience of arrangement.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a first light emitting device 41 according to an embodiment of the invention; the first light emitting element 41 may be a blue light chip 411, a light emitting side of the blue light chip 411 is provided with a fluorescent layer 412, light emitted from the blue light chip 411 excites red and green fluorescent powder of the fluorescent layer 412 to emit white light, a certain proportion of diffusion powder may be mixed in the fluorescent powder, light eyes are eliminated, and the display effect of the display panel 2 in the area corresponding to the first opening K is optimized.

Referring to fig. 5 and fig. 6, in some alternative embodiments, each supporting plate 42 includes a central area A2 close to the center of the brightness compensation assembly 4 and an edge area A1 far from the center of the brightness compensation assembly 4, the first light emitting device 41 is disposed on the edge area A1, and the first light shielding layer Z1 is disposed on at least one side of the supporting plate 42 facing the display panel 2 in the central area A2 in the unfolded state.

It should be noted that, when the supporting plates 42 are spliced to each other to form a circle, the central area A2 is a partial area of the circle close to the center of the circle, and in the unfolded state, the optical element 3 is mainly disposed opposite to the central area A2 of the supporting plate 42, and by disposing the first light shielding layer Z1 in the central area A2 of the supporting plate 42, on one hand, external light can be blocked from entering the optical element 3, and on the other hand, the first light shielding layer Z1 can also play a role of shielding the optical element 3, thereby avoiding the problem that the optical element 3 is visible in the unfolded state.

The first light shielding layer Z1 may be made of an opaque material such as an ink material or a black matrix material, and may be formed by ink-jet printing, vapor deposition, screen printing, and other processes, without any particular limitation.

Referring to fig. 3 and 4, in some optional embodiments, the display device further includes a second light shielding layer Z2 partially disposed between the display panel 2 and the backlight module 1, the second light shielding layer Z2 extends to the first opening K by a predetermined distance, and in a contracted state, at least a portion of the first light shielding layer Z1 on the supporting plate 42 abuts against the second light shielding layer Z2.

It should be noted that the second light shielding layer Z2 extends to the first opening K by a predetermined distance to shield the light emitted from the display panel 2 and/or the backlight module 1, so as to prevent the light from affecting the working effect of the optical element 3, for example, affecting the shooting effect of the camera, but the light shielding range of the second light shielding layer Z2 is limited, in the embodiment of the present invention, the supporting plate 42 is retracted into the first opening K in the retracted state, and further drives the first light shielding layer Z1 on the supporting plate 42 to at least partially abut against the second light shielding layer Z2, so that the first light shielding layer Z1 and the second light shielding layer Z2 cooperate with each other to shield the light emitted from the display panel 2 and/or the backlight module 1, thereby preventing the light from entering the camera, and ensuring the normal shooting effect of the camera.

The second light-shielding layer Z2 may specifically adopt black PET (Polyethylene Terephthalate) to ensure a light-shielding effect, and compared with a form of adopting two dispensing as a fixed light-shielding layer in the prior art, the first light-shielding layer Z1 in the embodiment of the present invention is only abutted to the second light-shielding layer Z2 when the optical element 3 is in operation, and is in a deployed state along with the supporting plate 42 when the optical element 3 is not in operation, so that normal display of the display panel 2 in a region corresponding to the first opening K is not affected. In the embodiment of the invention, the first shading layer Z1 can be abutted against the second shading layer Z2 when the optical element 3 works instead of two dispensing steps in the prior art by only using the second shading layer Z2 as one dispensing step, and the first shading layer Z1 and the second shading layer Z2 together shade the light emitted by the display panel 2 and/or the backlight module 1, so that the part of the light emitted is prevented from entering the camera, and the normal shooting effect of the camera is ensured.

In order to ensure that the first light shielding layer Z1 can abut against the second light shielding layer Z2 at least partially, in some alternative embodiments, the depth of the first opening K in the thickness direction of the display device is smaller than the radius of the brightness compensation element 4 in the thickness direction perpendicular to the display device.

It can be understood that, since the brightness compensation module 4 needs to be retracted into the first opening K in the retracted state, when the brightness compensation module 4 includes a plurality of fan-shaped support plates 42, the radius of the brightness compensation module 4, that is, the radius of the fan-shaped support plates 42, the first shading layer Z1 is disposed in the central area A2 of the support plates 42, in order to ensure that the first shading layer Z1 can be abutted against the second shading layer Z2, and the abutted part of the first shading layer Z1 can be shielded in a sufficiently large area, the radius of the brightness compensation module 4, that is, the radius of the support plates 42 needs to be increased, so that more first shading layers Z1 can be inserted into the first opening K and abutted against the second shading layer Z2. The depth of the first opening K in the thickness direction of the display device and the specific size of the radius of the brightness compensation element 4 in the thickness direction perpendicular to the display device need to be selected according to the required contact area of the first light shielding layer Z1 and the second light shielding layer Z2, and are not particularly limited.

Referring to fig. 3 and 4, in some alternative embodiments, the backlight module 1 includes a frame 11 and a light guide plate 12 disposed in the frame 11, the frame 11 has a side surface facing the first opening K, the side surface has an opening T, and in a contracted state, the first light emitting element 41 of the brightness compensation assembly 4 at least partially extends into the opening T to emit light to the light guide plate 12.

The light guide plate 12 can convert the linear light source of the first light emitting device 41 into a surface light source by using the principle of total reflection of light, and then emit the light from the front surface of the light guide plate 12 to the display panel 2 by breaking the reflection condition by providing light guide points or the like. Alternatively, the light guide plate 12 may be made of a polycarbonate plate material or an acrylic material with a high refractive index and without light absorption, and is not particularly limited.

In order to enable the light emitted from the first light emitting element 41 to irradiate the light guide plate 12, the frame 11 of the backlight module 1 is configured to fixedly support the light guide plate 12, and the like, the frame 11 is provided with an opening T on a side surface thereof, and in a contracted state, at least a portion of the first light emitting element 41 of the brightness compensation assembly 4 extends into the opening T, so as to ensure the stable relative arrangement of the first light emitting element 41 and the light guide plate 12, and improve the utilization rate of the light emitted from the first light emitting element 41 to the light guide plate 12.

Optionally, the backlight module 1 further includes a diffusion layer 14 and a light-emitting layer 15 stacked on the light-emitting side of the light guide plate 12, where the light-emitting layer 15 may also be referred to as BEF (bright enhancement Film), and is an optical Film formed by precisely forming a layer of uniform prism pattern on a surface of a PET (Polyethylene Terephthalate) with good transparency by using an acrylic resin. The front brightness can be improved by about 100% by assembling it in front of the backlight and focusing the light emitted from the light source toward the user of the display device. The light not used outside the viewing angle is recycled by the light re-reflection effect and collected at the most appropriate angle.

In one embodiment, the diffusion layer 14 may also be referred to as a diffusion plate (Diffuser), and its main function is to provide a uniform surface light source for the display panel 2. The base material of the diffusion layer 14 is selected from materials with high light transmittance such as PET (polyethylene terephthalate), PC (Polycarbonate), PMMA (polymethyl methacrylate). The diffusion layer 14 can be made by adding a particle of chemical particle as a scattering particle into the diffusion film substrate, and the fine particle of the diffusion layer 14 is dispersed between the finger layers, so that the light will continuously pass through two media with different refractive indexes through the diffusion layer 14, and at the same time, the light will generate many refraction, reflection and scattering phenomena, thus creating the optical diffusion effect.

Referring to fig. 3 and 4, in some alternative embodiments, the backlight module 1 further includes a second light emitting element 13 disposed on a side of the light guide plate 12 away from the first opening K, and light emitted from the second light emitting element 13 faces a side surface of the light guide plate 12 opposite to the first opening K.

It can be understood that, since the light emitted from the second light emitting element 13 is directed to the opposite side of the light guide plate 12, that is, the second light emitting element 13 is a side-in type light emitting element, since the first light emitting element 41 only emits light to the light guide plate 12 in the contracted state to play a role of supplementing light intensity, and the main light emission of the backlight module 1 is realized by the second light emitting element 13, the light intensity and the illumination range of the second light emitting element 13 are usually greater than those of the first light emitting element 41.

Optionally, the maximum size of the first light emitting element 41 is smaller than the maximum size of the second light emitting element 13. Specifically, the first light emitting element 41 may employ a Micro LED, and the second light emitting element 13 may employ a Mini LED. Of course, other suitable size light emitting diodes may be used, and are not particularly limited.

In order to effectively fix the supporting plate 42 and the frame body 11, in some alternative embodiments, the display device further includes a fixing adhesive layer 5, and the supporting plate 42 and the frame body 11 are connected by the fixing adhesive layer 5.

The fixing Adhesive layer 5 may be made of a double-sided Adhesive, an OCA (optical Clear Adhesive, an optical Adhesive, an acrylic Adhesive material, or a silicone Adhesive, which has a certain viscosity, as long as it can effectively adhere between the support plate 42 and the frame 11.

Referring to fig. 2 and 3, in some alternative embodiments, the optical element 3 is telescopically arranged relative to the backlight module 1, and the optical element 3 is connected to the supporting plate 42 through the telescopic member 6.

It should be noted that the optical element 3 and the supporting plate 42 are connected by the extensible member 6, so that the extensible member 3 extends and retracts the supporting plate 42, thereby achieving the linkage between the optical element 3 and the supporting plate 42, specifically, when the optical element 3 does not need to work, for example, when a camera is not needed to shoot, the optical element 3 retracts downward relative to the backlight module 1, and meanwhile, the extensible member 6 drives the supporting plate 42 to retract from the first opening K, that is, the extensible member 6 drives the supporting plate 42 to be in an extended state; when the optical element 3 works, for example, a camera is required to shoot, the optical element 3 moves towards the direction of the first opening K, and the expansion piece 6 drives the supporting plate 42 to contract towards the inside of the first opening K, so that the supporting plate 42 avoids the optical element 3, the optical element 3 is exposed, and the optical element 3 works conveniently.

Through setting up extensible member 6 in order to realize the linkage between optical element 3 and the backup pad 42 in this implementation, do not need additionally to set up other power and drive backup pad 42 and remove along with optical element 3's state, simple structure, and easily operation.

Optionally, referring to fig. 8, fig. 8 is a schematic structural diagram of the expansion element 6 according to an embodiment of the present invention. The telescopic member 6 includes at least two telescopic rods 61, each telescopic rod 61 can relatively extend and retract when the optical element 3 moves to adjust the state of the supporting plate 42, and the specific number of the telescopic rods 61 and the length thereof need to be selected according to parameters such as the size of the supporting plate 42 and the extending and retracting length of the optical element 3, and are not particularly limited.

Of course, the extension and retraction may also adopt other structures, such as a spring, a Z-shaped elastic sheet and other parts with certain extension and retraction performance.
