First, in the present exemplary embodiment, there is provided a camera assembly for a display device, as shown in fig. 1 and 2, the display device including a display panel 10, the camera assembly 20 including: a light transmission layer 210, a diaphragm layer 220 and a camera 230. The light transmission layer 210 includes a first region located at the light emitting side of the display panel 10 and a second region extending to the backlight side of the display panel 10, the light transmission layer 210 includes a plurality of light transmission lines 211 arranged to extend from the first region to the second region, and the light transmission lines 211 are used to transmit light; the barrier layer 220 is disposed on a side of the first region away from the display panel 10, the barrier layer 220 includes a plurality of barrier lines 212, an extending direction of the barrier lines 212 intersects an extending direction of the light transmission lines 211, and each barrier line 212 includes a light shielding state and a light transmitting state; the camera 230 is disposed on a side of the second region away from the display panel 10, and is connected to each of the transmission light beams for receiving the light beams obtained by each of the transmission light beams through the barrier line 212.

Wherein, the light-emitting side of the display panel 10 is the side of the display panel 10 emitting light, and the backlight side of the display panel 10 is the side opposite to the light-emitting side; when the barrier line 212 is in the light blocking state, light cannot or hardly pass through the barrier line 212, and when the barrier line 212 is in the light transmitting state, light can pass through all or substantially all of the barrier line 212.

When the camera assembly 20 provided by the present disclosure is used for shooting with a display device, the light barrier lines 212 in the light barrier layer 220 can be sequentially switched to a light-transmitting state, the light transmission lines 211 of the light transmission layer 210 are used to sequentially transmit the light entering under the light-transmitting state of each light barrier line 212 to the camera 230, and the camera 230 synthesizes the light acquired successively into a target image, so as to complete the shooting operation of a target area, without opening a hole on the display panel 10 or using the semitransparent display panel 10, so that the display panel 10 can achieve an ultra-high screen ratio close to 100%; when the camera assembly 20 stops shooting, the barrier lines 212 of the barrier layer 220 can be in a transparent state, so that the display effect of the display panel 10 is ensured.

As shown in fig. 4, each optical transmission line 211 includes a high-folding layer 2112, a low-folding layer 2111 and a plurality of refraction elements, the low-folding layer 2111 covers the high-folding layer 2112, the plurality of refraction elements are disposed in the high-folding layer 2112 in the first area at intervals, and each refraction element is disposed in one-to-one correspondence with each position of the light barrier line 212, and the refraction elements are used for changing the transmission direction of incident light so that the incident light is transmitted toward one end of the camera 230 at the high-folding layer 2112; the refractive index of the high-refractive layer 2112 is greater than the refractive indices of the low-refractive layer 2111 and the refractive element.

Specifically, the light barrier lines 212 intersect with the extending direction of the light transmission lines 211, that is, a plurality of light transmission lines 211 are correspondingly arranged under each light barrier line 212, a plurality of light barrier lines 212 are correspondingly arranged on each light transmission line 211, and a refraction member is arranged on each light transmission line 211 at a position corresponding to the light barrier line 212. As shown in fig. 5 and 6, when the barrier line 212 is switched to the light-transmitting state, the light projected into the light transmission line 211 through the barrier line 212 can be refracted in the refraction member, so that the incident light is transmitted in the light transmission line 211 toward one end connected to the camera 230, thereby achieving the purpose of transmitting the light of the target image on the light-emitting side of the display panel 10 to the camera 230 on the backlight side of the display panel 10. When light transmits in optical transmission line 211, partial light need pass through a plurality of refraction pieces, through the refracting index that makes high folded layer 2112 be greater than the refracting index of low folded layer 2111 and refraction piece, can make light incident to refraction piece after, jet out after wherein total reflection changes propagation direction, can make light meet refraction piece when entering in the transmission course simultaneously, can not produce the total reflection, guaranteed the transmission of light.

As shown in fig. 3, the refractive element includes a refractive body 2113 and a reflective layer 2114, and the reflective layer 2114 is located on a side of the refractive body 2113 close to the display panel 10. After the light enters the refraction body 2113, the light can be totally reflected by the reflection layer 2114, and is prevented from being refracted out of the low refraction layer 2111.

Specifically, the refraction body 2113 includes an incident surface, a reflection surface and a bottom surface, the incident surface, the reflection surface and the bottom surface enclose to form the refraction body 2113, the incident surface is located on one side of the reflection surface close to the light outlet of the transmission line, the reflection layer 2114 is attached to the bottom surface, an included angle between the incident surface and the bottom surface is 30 ° to 55 °, such as 30 °, 40 °, 45 °, 50 °, 55 °, and the like, which are not listed here, and of course, the included angle between the incident surface and the bottom surface may also be smaller than 30 ° or larger than 55 °; the included angle between the reflection surface and the bottom surface is 80 ° to 100 °, for example, 80 °, 85 °, 90 °, 95 °, 100 °, and the like, which are not listed here, but of course, the included angle between the incidence surface and the bottom surface may be smaller than 90 ° or larger than 100 °. By setting the included angle between the incident surface and the bottom surface to be 30-55 degrees, the light transmission line 211 can have a sufficient light entering angle after the light barrier line 212 is switched to a light transmission state; by setting the included angle between the reflecting surface and the bottom surface to 80-100 degrees, incident light can be reflected and transmitted toward one end connected with the camera 230.

Specifically, an orthographic projection of the refractive body 2113 on the display panel 10 is within an orthographic projection of the reflective layer 2114 on the display panel 10. The light rays entering the refraction body 2113 can be totally reflected by the reflection layer 2114 when being refracted to the bottom surface, so that the light rays are prevented from being incident to the low-refraction layer 2111 below the bottom surface. Wherein the reflective layer 2114 can be sized and formed to conform or substantially conform to the bottom surface.

Specifically, in the extending direction of the optical transmission line 211, the sum of the lengths of the refractive elements in each optical transmission line 211 is 15% to 25%, for example, 15%, 18%, 20%, 22%, 25%, etc., of the length of the optical transmission line 211 in the first region, which is not specifically listed here, and of course, in the extending direction of the optical transmission line 211, the sum of the lengths of the refractive elements in each optical transmission line 211 in the length of the optical transmission line 211 in the first region may also be less than 15% or greater than 25%. As shown in fig. 7, by setting the length of the refraction element in the optical transmission line 211 to be 15% to 25% of the length of the first area of the optical transmission line 211, when the shooting is stopped, the display light of the display panel 10 can normally pass through each optical transmission line 211, thereby avoiding the reflection layer 2114 from causing a large influence on the projection of the light, and ensuring the display effect of the display panel 10.

As shown in fig. 3, the extending direction of the barrier line 212 is the x direction, the extending direction of the optical transmission line 211 is the y direction, and the extending direction of the barrier line 212 is perpendicular to the extending direction of the optical transmission line 211. By making the extending direction of the diaphragm lines 212 perpendicular to the extending direction of the light transmission lines 211, the light transmission lines 211 can be disposed at the positions corresponding to each diaphragm line 212, the diaphragm lines 212 can be disposed at the positions corresponding to each light transmission line 211, and the number of the light transmission lines 211 and the diaphragm lines 212 can be reduced in the first region with the same area.

As shown in fig. 8, the light barrier line 212 is an electrochromic line, which includes a first transparent glass layer 2111, a first transparent conductive layer 2122, a first electrochromic layer 2123, an ion conductive layer 2124, a second electrochromic layer 2125, a second transparent conductive layer 2126, and a second transparent glass layer 2127 from one end to the other end at a time, and by applying power to the first transparent conductive layer 2122 and the second transparent conductive layer 2126, ions can move in the first electrochromic layer 2123, the ion conductive layer 2124, and the second electrochromic layer 2125, and the movement direction of ions in the ion conductive layer 2124 is as indicated by arrows in the figure. By adopting the electrochromic line, the transparent filling and the shading filling of the switching electrode lines can be facilitated, the switching speed is high, the reliability is high, and the controllability is strong.

Specifically, as shown in fig. 3, the first region has a rectangular shape, and the first region has a width of 1mm to 10mm in the x direction and a height of 1mm to 10mm in the y direction. Of course, the width of the first region may also be less than 1mm or greater than 10mm, and the height may also be less than 1mm or greater than 10 mm; the first region may also be formed in a shape of a circle, an ellipse, a triangle, etc., which is not limited by the present disclosure.

Specifically, the transmission line outside the first region may further include a protection layer, and the protection layer is wrapped on the low-folding layer 2111 to prevent the light from entering the optical transmission line 211 from outside the first region and affecting the shooting effect. Needless to say, the light transmission line 211 outside the first region may be shielded by the display panel 10 and a member such as a housing in the display device without providing a protective layer.

Specifically, the camera 230 sequentially acquires the light entering after each diaphragm line 212 is transparent, that is, sequentially acquires the local image of the target area entering after each diaphragm line 212 is transparent. As an example, stitching multiple partial images into an imposition image typically uses five steps: (1) image preprocessing: the method comprises the following steps of performing basic operations of digital image processing (such as denoising, edge extraction, histogram processing and the like), establishing a matching template of an image, performing certain transformation (such as Fourier transformation, wavelet transformation and the like) on the image, and the like; (2) image registration: determining the corresponding positions of templates or characteristic points in the images to be spliced in the reference image by adopting a certain matching strategy, and further determining the transformation relation between the two images; (3) establishing a transformation model: calculating parameter values in the mathematical model according to the corresponding relation between the template or the image characteristics, thereby establishing a mathematical transformation model of the two images; (4) unified coordinate transformation: converting the images to be spliced into a coordinate system of a reference image according to the established mathematical conversion model to finish unified coordinate transformation; (5) fusion and reconstruction: and fusing the overlapped areas of the images to be spliced to obtain a spliced and reconstructed smooth seamless panoramic image. The algorithm for synthesizing the acquired multiple local images into the full-page image is not limited by the disclosure, and all changes in the synthesis method belong to the protection scope of the disclosure.

The following are embodiments of the disclosed method that may be used to implement embodiments of the disclosed apparatus. For details not disclosed in the embodiments of the disclosed method, refer to the embodiments of the disclosed apparatus.

The present exemplary embodiment provides another image pickup method for a display device including a display panel, as shown in fig. 8, the image pickup method including:

step S100, providing the camera assembly;

step 200, at least closing a display area corresponding to the first area on the display panel;

step S300, sequentially switching the diaphragm line from a shading state to a light-transmitting state and then to a shading state;

s400, enabling the camera to successively acquire light rays entering the camera after each diaphragm line is switched into a light-transmitting state through the light transmission line;

and step S500, synthesizing the successively acquired light rays to acquire a target image.

According to the shooting method provided by the disclosure, the light entering of the light barrier lines in the light barrier layer can be sequentially switched to the light transmitting state, then the light entering of the light barrier lines in the light transmitting state is sequentially transmitted to the camera through the light transmission lines of the light transmission layer, the camera synthesizes the light acquired successively into a target image, the shooting operation of a target area can be completed, no hole needs to be formed in the display panel or a semitransparent display panel is adopted, and the display panel can reach the ultrahigh screen occupation ratio close to 100%; when the camera component stops shooting, the diaphragm lines of the diaphragm layer can be in a light-transmitting state, and the display effect of the display panel is ensured.

Next, each step of the image pickup method in the present exemplary embodiment will be further described.

In step S100, a camera assembly as described above is provided.

Specifically, as shown in fig. 1 and 2, the camera assembly 20 is provided on the display panel 10.

In step 200, at least a display area corresponding to the first area on the display panel is closed.

Specifically, when the target area starts to be photographed, at least the display area on the display panel 10 corresponding to the first area is closed, so as to avoid the influence of the light transmission layer 210 on the display panel 10 on the photographing effect. The size of the closed display area can be the same as that of the first area, and can also be slightly larger than that of the first area, so that the influence of the light of the display area on the shooting effect is further avoided.

In step S300, the diaphragm line is sequentially switched from the light-shielding state to the light-transmitting state and then to the light-shielding state.

Specifically, as shown in fig. 3, the controller controls each barrier line 212 to sequentially transmit light, that is, one barrier line 212 is switched from the light-shielding state to the light-transmitting state and then switched to the light-shielding state, and then the other barrier line 212 is switched from the light-shielding state to the light-transmitting state and then switched to the light-shielding state until all barrier lines 212 complete the light-transmitting switching operation. When the light transmission is performed by sequentially switching the states of the respective barrier lines 212, the light transmission operation may be performed sequentially from one edge region of the first region and then toward the other opposite edge. The diaphragm lines 212 may be electrochromic lines, so that the light transmitting state and the light shielding state of each diaphragm line 212 may be switched by sending an electrical signal to the diaphragm line, thereby improving stability and reliability of the shooting process.

In step S400, the camera sequentially obtains the light entering after each diaphragm line is switched to the light-transmitting state through the light transmission line.

Specifically, as shown in fig. 5 and 6, when the barrier lines 212 sequentially transmit light, the light transmission line 211 can transmit the light entering after the barrier lines 212 transmit light to the camera 230, and the camera 230 sequentially obtains the light entering after the barrier lines 212 transmit light, that is, sequentially obtains the local images of the target area entering after the barrier lines 212 transmit light.

In step S500, the successively acquired light rays are synthesized to acquire a target image.

Specifically, after the light transmission operation of each barrier line 212 is completed in sequence, the camera 230 acquires a plurality of partial images of the target area, and then synthesizes the plurality of partial images through the processor to obtain a complete image of the target area, thereby implementing the framing shooting of the target area. The above-mentioned embodiments of the camera assembly have been described for the exemplary image synthesis method, and are not described herein again.

Further, the image pickup method provided by the present disclosure further includes step S600: after the image pickup is completed, each diaphragm line 212 is switched to a light-transmitting state.

Specifically, after the shooting is completed, the camera assembly 20 is turned off or in a sleep state, and each of the barrier lines 212 in the barrier layer 220 is in a transparent state at this time, so as to ensure that the display light of the display panel 10 is transmitted normally.

Embodiments of the present disclosure also provide a display device, which includes a display panel 10 and the camera assembly 20 of the above embodiment disposed on the display panel 10. The specific type of the display device is not particularly limited, and any display device commonly used in the art may be used, specifically, for example, a liquid crystal display, an OLED display, a mobile device such as a mobile phone, a wearable device such as a watch, a VR device, and the like.

Further, the display panel 10 further includes: the display device comprises a substrate, a display layer, a packaging layer and an optical adhesive layer, wherein the display layer is arranged on one side of the substrate; the packaging layer is arranged on one side of the display layer far away from the substrate, the first area of the light transmission layer 210 is arranged on one side of the packaging layer far away from the substrate, the second area is arranged on one side of the substrate far away from the display layer, and the diaphragm layer 220 is arranged on one side of the first area far away from the packaging layer; the optical adhesive layer is disposed on a side of the encapsulation layer away from the substrate and covers the light barrier layer 220, and a recessed area is formed in a region of the optical adhesive layer corresponding to the light barrier layer 220, so that the first region of the light transmission layer 210 and the light barrier layer 220 are located in the recessed area.

The concave area is formed in the area corresponding to the diaphragm layer 220, so that the surface of the optical adhesive layer away from the substrate is a horizontal plane, the protrusion of the area of the display panel 10 caused by the camera assembly 20 is avoided, and the display effect of the display panel 10 is improved. Of course, the transmission layer 210 and the light barrier layer 220 can be disposed on other layers of the display panel 10, such as a glass cover plate on the upper surface, which is not limited by the present disclosure. Wherein, the Optical adhesive layer can be OCA (Optical clear adhesive tape).
