Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

The following disclosure provides many different embodiments or examples for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

In the related art, the scheme of an off-screen camera of an electronic device such as a mobile phone generally includes that the camera is integrally arranged below a display screen, the camera includes a lens and an image sensor, and the thickness of the lens is relatively high, so that the overall thickness of the electronic device is relatively thick. Therefore, in order to reduce the overall thickness of the electronic device, it is generally necessary to cut out or open a slot in the display screen, and extend the camera into the hole or slot to reduce the thickness of the electronic device. However, in this solution, the thickness of the electronic device is still large, and the whole structure of the display screen needs to be destroyed, which makes the manufacturing process difficult.

Referring to fig. 1, the present disclosure provides a display panel 100, in which the display panel 100 includes a layer structure 10 and a plurality of microlenses 20, and the plurality of microlenses 20 are embedded in the layer structure 10. The layer structure 10 includes a base layer 11 that transmits light and a mask layer 12 formed on the base layer 11, the mask layer 12 having a light transmitting region 101. The microlenses 20 are disposed corresponding to the light-transmitting regions 101, and the plurality of microlenses 20 are used to image the target object onto the image sensor 110 located on the side of the base layer 11 away from the masking layer 12 through the plurality of light-transmitting regions 101.

Referring to fig. 2, the display screen 100 according to the embodiment of the present disclosure can be applied to a display module 200 and an electronic device 300. The display assembly 200 includes the image sensor 110 and the display screen 100 as described above, and the display screen 100 covers the image sensor 110.

It is understood that the display assembly 200 is located at the front side of the electronic device 300. Specifically, the electronic device 300 includes a housing 310, and the display assembly 200 is disposed in the housing 310. For example, the display device 200 may be fixed to the housing 310 by a dispensing process. The housing 310 is a support of the electronic device 300, and is used for supporting parts of the electronic device 300. The housing 310 may also reduce the impact on the internal components of the electronic device 300.

In the display screen 100, the display module 200 and the electronic device 300 of the embodiment of the application, the plurality of microlenses 20 are used for imaging the target object on the image sensor 110 located at one side of the thickness direction of the display screen 100 through the plurality of light-transmitting areas 101, so that the electronic device 300 can be ensured to have a front-end shooting function, and the screen occupation ratio of the electronic device 300 can be improved. In addition, the microlens 20 is used for imaging, so that the thickness of the display assembly 200 and the electronic device 300 can be reduced, and the user experience is improved.

And the micro-lenses 20 are embedded in the layer structure 10, so that the structure of the display screen 100 does not need to be damaged after the display screen 100 is manufactured and formed, and the manufacturing process difficulty is low.

It is understood that the screen occupation ratio of the electronic device 300 refers to an area ratio of a region corresponding to the display region of the display screen 100 in the front surface of the electronic device 300 to other regions of the front surface in the front surface of the electronic device 300. Improving the screen duty ratio of the electronic device 300 may improve the visual effect of the electronic device 300, thereby improving the user experience.

It should be noted that the display screen 100 covers the image sensor 110, which means that the orthographic projection of the image sensor 110 on the lower surface of the display screen 100 is located in the lower surface. The plurality of microlenses 20 may be arranged in a horizontal direction or in an oblique direction.

It is understood that each microlens 20 can form an image on the image sensor 110, and therefore, the image sensor 110 can collect a plurality of images formed by a plurality of microlenses 20, and the finished image can be obtained after processing the plurality of images collected by the image sensor 110.

In one example, referring to fig. 3, the number of the microlenses 20 is 5, so that the image sensor 110 first acquires 5 partial images, and after processing, a complete image is obtained.

In another example, referring to fig. 4, the number of the microlenses 20 is 5, so that the image sensor 110 first acquires 5 partial images, and after processing, a complete image is obtained.

It should be noted that, in the thickness of the display screen 100, there may be one microlens 20 or a plurality of microlenses arranged in a stacked manner. As in the embodiment of fig. 4, the microlenses 20 are two in a stacked arrangement across the thickness of the display screen 100. In other embodiments, there may be 3 or more than 3 microlenses 20.

The layer structure 10 has a plurality of layers, for example, one layer is used for generating light so that the display screen 100 can display pictures, and another layer is used for filtering certain specific wavelengths of light (for example, ultraviolet rays) in natural light.

In this embodiment, the display panel 100 may be an Organic Light-Emitting Diode (OLED) display panel 100, and the OLED display panel 100 has good Light transmittance and can pass visible Light and infrared Light. Therefore, the OLED display 100 does not affect the image sensor 110 to receive light when the content effect is displayed. The display screen 100 may also be a Micro LED display screen 100.

In the present embodiment, the electronic device 300 may be any of various types of computer system apparatuses (only one form is exemplarily shown in fig. 2) that are mobile or portable and perform wireless communication, for example. Specifically, the electronic apparatus 300 may be a mobile phone or a smart phone, such as an iPhone system (apple system) based phone, an Android system (Android system) based phone, a portable game device (e.g., an iPhone (apple phone), a laptop, a Palmtop (PDA), a portable internet device, a music player, and a data storage device, other handheld devices, and devices such as a watch, and the electronic apparatus 300 may also be other wearable devices (e.g., devices such as smart glasses, a smart watch, or a Head Mounted Display (HMD)).

Specifically, referring to fig. 5, the image sensor 110 includes a circuit board 111 and a photosensitive chip 112. The photosensitive chip 112 is disposed on the circuit board 111. For example, the photosensitive chip 112 is fixed on the circuit board 111 by a surface mounting process. The plurality of microlens 20 arrays are used to image the target object on the photosensitive chip 112 through the plurality of light-transmitting regions 101.

The circuit board 111 may be a rigid circuit board or a flexible circuit board. In this embodiment, the circuit board 111 is a rigid circuit board. For example, the Circuit Board 111 is a Printed Circuit Board (PCB). Further, when the circuit board 111 is a rigid circuit board, the display assembly 200 further includes a flexible circuit board 113, and the flexible circuit board 113 is connected to the circuit board 111. The flexible circuit board 113 may be connected to a motherboard of the electronic device 300 to communicate with the motherboard of the electronic device 300.

The photo-sensing chip 112 is a bare chip (die). The photosensitive chip 112 may employ a Complementary Metal Oxide Semiconductor (CMOS) photosensitive element or a Charge-coupled Device (CCD) photosensitive element.

The photosensitive chip 112 can be electrically connected to the circuit board 111 by gold wires. In one example, after the photo sensor chip 112 and the circuit board 111 are connected by gold wire, gold wire can be packaged by the packaging material to prevent the gold wire from breaking, thereby improving the stability of the image sensor 110.

Further, the circuit board 111 is formed with a groove 114, and the photosensitive chip 112 is accommodated in the groove 114. Thus, the overall thickness of the image sensor 110 is thinner, which is beneficial to reducing the thickness of the display module 200.

Referring to fig. 5, in some embodiments, a plurality of microlenses 20 are disposed on a side of masking layer 12 facing away from base layer 11.

Specifically, the base layer 11 may be made of a rigid material such as glass, or may be made of a flexible material such as an organic material. The masking layer 12 may be provided with the display pixels and traces of the display screen 100. The masking layer 12 may be formed on the base layer 11 through a photolithography process. As shown in the orientation of fig. 5, a plurality of microlenses 20 are located over masking layer 12. Alternatively, the masking layer 12 may be formed by wafer growth, deposition, etching, etc.

The micro-lenses 20 may be bonded to one surface of the mask layer 12 by optical bonding, and the micro-lenses 20 may also be formed on one surface of the display panel 100 by wafer level optics (wafer level optics).

Referring to fig. 5, in some embodiments, the layer structure 10 further includes an organic film 13 covering the mask layer 12, and a plurality of microlenses 20 are sandwiched between the organic film 13 and the mask layer 12. In this way, the organic film layer 13 can protect the plurality of microlenses 20 and the masking layer 12, and prevent impurities such as moisture and dust from entering the masking layer 12. The organic film layer 13 is made of Polyimide (PI), for example, so that the toughness of the organic film layer 13 is better, the thickness of the organic film layer 13 is lower, and the thickness of the display screen 100 is effectively reduced.

Referring to fig. 5, in some embodiments, the layer structure 10 further includes a polarizing layer 14 stacked on the organic film layer 13, wherein the polarizing layer 14 is located on a side of the organic film layer 13 facing away from the masking layer 12. Thus, the polarizing layer 14 can filter the light of natural light entering the display screen 100 in a specific vibration direction, and prevent the display screen 100 from reflecting the light to reduce the display effect of the display screen 100.

Referring to fig. 5, in some embodiments, the display panel 100 further includes a cover plate 15 on a side of the polarizing layer 14 facing away from the organic film layer 13. Alternatively, the cover plate 15 is disposed in a stack with the polarizing layer 14 and covers the polarizing layer 14. The cover plate 15 is made of a highly light-transmitting material such as glass. The cover plate 15 can protect the display screen 100, and the service life of the display screen 100 is prolonged. The cover plate 15 may be fixedly attached to the polarizing layer 14 by means of optical glue.

It is to be noted that the base layer 11, the organic film layer 13, the polarizing layer 14, and the cover plate 15 are all transparent as a whole, and thus light can reach the image sensor 110 through these layer elements.

Referring to fig. 6, in some embodiments, the mask layer 12 includes a display area 121, the display area 121 includes a first area 122 and a second area 123, and the second area 123 is connected to the first area 122. The first area 122 and the second area 123 both distribute the pixel array. The light-transmitting region 101 is positioned between the adjacent pixels 124 of the first region of the display region 121.

In this way, the light-transmitting region 101 is located between two adjacent pixels 124, which can prevent the light-transmitting region 101 from interfering with the pixels 124, so that the light-transmitting region 101 is easier to form, and the image sensor 110 is convenient to capture the target object image.

Further, the pixel density of the first region 122 is smaller than that of the second region 123. It is understood that pixel density refers to the ratio of the number of pixels per unit area to the area. In this way, the light-transmitting region 101 can be more easily formed between the adjacent pixels 124 in the first region 122, and because there are fewer pixels 124 in the first region 122, the influence of the light generated by the pixels 124 in the first region 122 on the image interference of the image sensor 110 is lower, which is beneficial to improving the imaging quality of the image sensor 110.

It will be appreciated that, as the display screen 100 has a layer structure 10, the edges of the layer structure 10 may be adhered together by glue, with no pixels at the edges of the layer structure 10. Therefore, a non-display area 125 is formed at the edge of the display screen 100, and a display area 121 is formed at the middle portion of the display screen 100.

The display area 121 may have a rectangular shape, a rounded rectangle, or the like. The non-display area 125 has a frame shape.

Since the mask layer 12(mask) has pixels 124 to display a picture, the mask layer 12 may also be referred to as a display layer.

The terms "first" and "second" are used herein for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In some embodiments, display screen 100 includes a layer structure 10 and a plurality of microlenses 20, layer structure 10 including a base layer 11 that is light transmissive and a masking layer 12 formed on base layer 11. The masking layer 12 has a light-transmitting region 101. The display area 121 includes a first area 122 and a second area 123, and the first area 122 and the second area 123 each distribute the pixel array. The light-transmitting region 101 is positioned between the adjacent pixels 124 of the first region of the display region 121. The pixel density of the first region 122 is less than the pixel density of the second region 123. The microlenses 20 are disposed corresponding to the light-transmitting regions 101, and the plurality of microlenses 20 are used to image the target object onto the image sensor 110 located on the side of the base layer 11 away from the masking layer 12 through the plurality of light-transmitting regions 101.

As shown in fig. 7, in some embodiments, a plurality of microlenses 20 are sandwiched between a base layer 11 and a masking layer 12. This may allow the microlens 20 to image the image sensor 110 through the base layer 11.

In some embodiments, the light-transmissive region 101 is a through hole formed in the mask layer 12. Alternatively, the light passes through the through hole of the mask layer 12 and the microlens 20 and then is incident on the image sensor 110. The light transmittance of the through-hole is large, so that the loss of light can be reduced. Of course, in some embodiments, the light-transmissive region 101 is a light-transmissive solid portion formed on the mask layer 12. For example, the light-transmitting region 101 may be made of a high-light-transmitting material such as resin. The light transmittance of the light-transmitting region 101 is greater than 90%.

In some embodiments, the plurality of light-transmissive regions 101 are arranged in an array. For example, the light-transmitting regions 101 may be arranged in a 6 × 6 matrix. Of course, the plurality of light-transmitting regions 101 may be arranged in other manners.

In some embodiments, each light-transmitting region 101 is disposed corresponding to one of the microlenses 20. Alternatively, the light-transmitting regions 101 and the microlenses 20 are in a one-to-one correspondence. In one example, the number of the light-transmitting regions 101 is 36, and the light-transmitting regions are arranged in a 6 × 6 matrix; the number of microlenses 20 is also 36, and arranged in a 6 x 6 matrix, as shown in fig. 9.

In some embodiments, the lateral dimension of the light-transmissive region 101 is less than 0.5 mm. When the light-transmitting area 101 is cylindrical, the radial dimension of the light-transmitting area 101 is less than 0.5 mm. Accordingly, the lateral dimension of the microlenses 20 is less than 0.5 mm; when the lateral cross-section of the microlens 20 is circular, the radial dimension of the microlens 20 is less than 0.5 mm.

Referring to fig. 5, in some embodiments, the display assembly 200 includes a connector 120, and the connector 120 is connected to the image sensor 110 and the display screen 100. In this manner, the image sensor 110 may be fixed to the display screen 100 by the connection member 120, such that the display assembly 200 forms an integral body, facilitating the mounting of the display assembly 200 to the housing 310 of the electronic device 300.

Specifically, in one example, the above connecting member 120 includes an adhesive, which adheres the image sensor 110 and the display screen 100. The adhesive is a colloid such as silicone adhesive. In this way, the image sensor 110 and the display screen 100 are bonded by using the adhesive, so that the connection between the image sensor 110 and the display screen 100 is more stable, and the process is simple.

It is understood that the circuit board 111 and the display screen 100 are adhesively bonded so as not to interfere with the image sensor 110 capturing the target object image. It should be noted that, when the display screen 100 further includes a shielding layer and a foam buffer layer, the adhesive is connected to the layer of the display screen 100 close to the image sensor 110.

Preferably, the adhesive seals the gap between the image sensor 110 and the display screen 100. Therefore, the adhesive can prevent foreign matters such as dust and water vapor from entering the photosensitive chip 112 and affecting the normal operation of the photosensitive chip 112. As long as it is stated, the adhesive surrounds the photo chip 112.

In order to facilitate the image sensor 110 to be disposed on the display screen 100, please refer to fig. 8, the display screen 100 is provided with a first positioning structure 102, the image sensor 110 is provided with a second positioning structure 104, and the image sensor 110 is positioned on the display screen 100 by the first positioning structure 102 and the second positioning structure 104.

In this way, the first positioning structure 102 and the second positioning structure 104 enable the image sensor 110 to be accurately disposed at the position of the display screen 100, and ensure that the micro lens 20 corresponds to the light-transmitting area 101.

In one example, the first positioning structure 102 is a positioning groove, and the second positioning structure 104 is a protrusion, and the protrusion is inserted into the positioning groove, so that the image sensor 110 is connected to the display screen 100 in a positioning manner.

In some embodiments, the display assembly 200 includes a light guide element 130 disposed between the display screen 100 and the image sensor 110, the light guide element 130 for guiding light passing through the light transmissive region 101 to the image sensor 110.

Thus, the light guide element 130 can transmit light more intensively to the microlens 20, which is beneficial for the microlens 20 to image, so that the image sensor 110 can acquire an external image with better quality.

The light guide element 130 may be made of a material with high light transmittance, such as polyester, to reduce light loss of the light guide element 130 during light guiding. The light guide element 130 may have a columnar shape or a bent shape. When the light guide element 130 has a bent shape or the like, the image sensor 110 and the plurality of light transmission regions 101 may be disposed to be offset.

The light guide element may be adhesively secured to the display screen 100 by an optical glue, thereby fixing the position of the light guide element.

Referring to fig. 9, in some embodiments, a plurality of microlenses 20 are connected by a connecting portion 21. Preferably, the connecting portion 21 and the micro lens 20 are an integral structure. The microlenses 20 and the connecting portions 21 are made of a material having high light transmittance such as resin, for example. It is understood that the microlens 20 has a curved surface so that the microlens 20 can perform light focusing imaging.
