[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0030] The camera device described in the following embodiments of the present application may be any device that can capture images with a lens, such as a camera, a camcorder, etc. The electronic device described in the following embodiments of the present application may be any electronic device with a camera device, such as a smart phone, a tablet computer, a laptop computer, a desktop computer, and wearable devices such as smart glasses and smart watches. The electronic device in the embodiments of the present application is preferably a smart phone.

[0031] The present application provides an embodiment of a camera device, such as Figure 1As shown, the camera device includes: a lens unit array 11 and a photosensitive unit array 12; wherein,

[0032] A lens unit array 11, wherein the lens unit array 11 is composed of a plurality of lenses;

[0033] The photosensitive unit array 12 is stacked on the lens unit array; the photosensitive unit array 12 is composed of a plurality of photosensitive units, and the plurality of photosensitive units are divided into a plurality of groups, each group of photosensitive units corresponds to a lens.

[0034] It can be understood that the camera device of the embodiment of the present application, the lenses and photosensitive units included therein are in the form of an array, which does not affect the normal use of the camera device. Compared with the camera device of the related art consisting of an integral lens (which occupies a large space) and a photosensitive unit, the camera device of the embodiment of the present application, which is composed of multiple lenses and multiple photosensitive units, has the beneficial effect of improving the resolution of the captured image due to the increase in the number of photosensitive units. Considering the limited space resources, each lens in the lens unit array 11 in the embodiment of the present application is implemented by a micro lens, which is small in size, occupies less space, and does not affect the normal collection of light.

[0035] The number of lenses and photosensitive units in the camera device of the embodiment of the present application is at least two, preferably three or more. Among the multiple photosensitive units in the photosensitive unit array 12, they are divided into at least two groups, preferably three or more photosensitive unit groups. The number of photosensitive unit groups is pre-designed or configured to be the same as the number of lenses, and which photosensitive unit group corresponds to which lens is pre-designed or configured. It can be understood that each lens in the lens unit array 11 can collect light (light signal) in the same scene, and each photosensitive unit group at least processes the light signal collected by the lens corresponding to it, such as converting the light signal collected by the corresponding lens into an electrical signal.

[0036] Those skilled in the art should know that, in addition to using an integral lens and a photosensitive unit, the camera device in the related art is usually located above the display screen in electronic devices such as smartphones. This setting above the display screen limits the development of full-screen phones and fails to increase the screen-to-body ratio of the display screen.

[0037] In an optional embodiment of the present application, unlike the method of setting the camera device above the display screen in the related art, the camera device can be set below the display screen. In order not to affect the normal display of the display screen and the normal shooting function of the camera device, each lens in the lens unit array 11 needs to be staggered with the display unit array of the display screen. The display unit of the display screen is the pixel unit of the display screen.

[0038] In an optional embodiment of the present application, if the camera device is arranged below the display screen, each lens in the lens unit array 11 corresponds to the gap between every two display units in the display unit array of the display screen. That is, each lens is arranged below the gap between every two display units. This arrangement below the gap between the display units makes full use of the gap space between the display units and reduces the space occupied by the lens. In addition, the gap between the display units can just pass light, which facilitates the normal collection of light by the lens and will not affect the normal use of the lens.

[0039] Each lens in the lens unit array 11 corresponds to a gap between every two display units in the display unit array of the display screen, and specifically may correspond to a gap between every two adjacent display units in the display unit array.

[0040] In the above scheme, considering that the number of display units in the display unit array of the display screen is usually greater than the number of lenses, there are two different situations caused by the number of display units being greater than the number of lenses in the lens arrangement:

[0041] First, below the display screen, for all display units in the display unit array, a lens may be disposed below the gap between every two adjacent display units, so that there is a lens below the gap between every two adjacent display units in the display unit array, and the gap space between every two adjacent display units in the display unit array is occupied by the lens, and there is no gap space not occupied by the lens.

[0042] Secondly, some display units can be selected from all the display units in the display unit array, and a lens can be set under the gap between every two adjacent display units among the selected display units. In this case, it is equivalent to that there is a gap space not occupied by the lens in the gap space between every two adjacent display units in all the display units in the display unit array.

[0043] From the first and second methods above, it can be seen that the number of lenses in the first case is less than the number of lenses in the second case. Compared with the first case, the second case can greatly save lens resources and avoid waste of lens resources.

[0044] Among them, the scheme of the second case can be: if the camera device is set below the display screen, each lens in the lens unit array 11 can correspond to the gap between every two adjacent display units in the partial display units (display units selected from all display units in the display unit array) of the display screen. In this case, it can be understood that if the selected partial display units are display units located in a certain area of ​​the display screen, such as display units in the central area of ​​the display screen, it can be considered that the lens unit array 11 is set below the central area of ​​the display screen through the aforementioned scheme. If the selected partial display units are display units located in a certain area of ​​the display screen, such as display units in the left area of ​​the display screen, it can be considered that the lens unit array 11 is set below the left area of ​​the display screen through the aforementioned scheme. That is, the lens unit array 11 can be set below a partial area of ​​the display screen. In addition, the lens unit array 11 can also be set below the entire display screen. The specific situation is flexibly set according to the actual use situation and is not specifically limited.

[0045] The present application provides an embodiment of an electronic device, such as Figure 2 As shown, the electronic device comprises: a camera device 1 and a display screen 2; wherein,

[0046] The display screen 2 includes a display unit array, and the display unit array is composed of a plurality of display units;

[0047] A camera device 1 is arranged below the display screen 2; the camera device 1 comprises a lens unit array, and the lens unit array is composed of a plurality of lenses; wherein each of the plurality of lenses corresponds to a gap between every two display units.

[0048] In the aforementioned scheme, the camera device of the electronic device is arranged below the display screen. Compared with the scheme in the related art in which the camera device of the electronic device is arranged above the display screen, the space occupied by the camera device on the display screen can at least be reduced. The camera device is arranged below the display screen, which will not cause space occupation of the display screen, so that the screen-to-body ratio of the display screen is greatly improved, providing a good foundation for realizing a full screen. In addition, the lens is arranged below the gap between the two display units, and light can reach the lens through the gap without affecting the normal use of the lens. The lens in the embodiment of the present application appears in the form of an array, and each lens in the lens unit array 11 is implemented by a micro lens, which is small in size and occupies little space.

[0049] It can be understood that the aforementioned solution is equivalent to setting the camera device 1 inside the electronic device. In this way, the camera device does not occupy the space of the display screen, the screen-to-body ratio of the display screen is increased, and the user's viewing experience will be greatly improved.

[0050] In an optional embodiment, each of the plurality of lenses corresponds to a gap between every two adjacent display units in some of the display units in the display unit array. Some display units may be selected, and a lens may be arranged below a gap between every two adjacent display units in the selected display units, thereby avoiding the problem of resource waste due to too many lenses.

[0051] In an optional embodiment, the camera device further includes a photosensitive unit array, the photosensitive unit array is stacked on the lens unit array; the photosensitive unit array is composed of a plurality of photosensitive units, the plurality of photosensitive units are divided into a plurality of groups, each group of photosensitive units corresponds to a lens in the lens unit array. The camera device in the embodiment of the present application is composed of a plurality of lenses and a plurality of photosensitive units, and the increase in the number of photosensitive units will bring about the beneficial effect of improving the resolution of the captured image.

[0052] In an optional embodiment, the photosensitive unit array stitches the images captured by the lenses corresponding to each group of photosensitive units to obtain a target image. In this optional embodiment, each photosensitive unit group at least processes the light signal captured by the lens corresponding to it, such as converting the light signal into an electrical signal, and each photosensitive unit group obtains a corresponding image. The photosensitive unit array stitches these images to obtain the image finally captured by the camera device. This realizes normal image capture of the camera device. Please refer to the subsequent related instructions for the specific stitching process, which will not be repeated here.

[0053] In an optional embodiment, the electronic device further includes a circuit board, the circuit board is connected to the camera device; the circuit board is arranged in parallel with the display screen 2; the camera device is accommodated in the space formed between the parallel circuit board and the display screen 2. In this optional embodiment, inside the electronic device, the circuit board and the display screen 2 are arranged in parallel, and the camera device is arranged in the space formed between the parallel circuit board and the display screen 2, so that the space formed between the circuit board and the display screen 2 is effectively utilized and not wasted. At the same time, the problem of increasing the thickness of the electronic device due to the camera device being arranged inside the electronic device is avoided.

[0054] In an optional embodiment, the electronic device further comprises a supporting component for supporting the circuit board and the display screen arranged in parallel, so that the space is formed between the circuit board and the display screen. In this optional embodiment, the supporting component is used to support the circuit board and the display screen 2 arranged in parallel, so as to fix the circuit board and the display screen 2 inside the electronic device.

[0055] Those skilled in the art can understand that the lens unit array and the photosensitive unit array involved in the embodiment of the electronic device can be understood by referring to the lens unit array 11 and the photosensitive unit array 12 in the aforementioned embodiment of the camera device. For other contents in the above embodiment of the electronic device that are the same as those in the aforementioned embodiment of the camera device, please refer to the aforementioned contents of the embodiment of the camera device, and the repeated parts will not be repeated.

[0056] The following is combined with Figures 3 to 7 The embodiments of the present application are further described in detail in the following sections.

[0057] Compared with the passive light emission of liquid crystal (LCD) display screens, organic light-emitting diode (OLED) display screens do not require backlights and use thinner organic material coatings and glass substrates (or flexible organic substrates) and other materials. When an electrical signal such as current passes through, these materials will emit light, thereby realizing the active light emission of the OLED display screen. In addition, the OLED display screen also has the advantages of being light and thin, having a large viewing angle, and saving power consumption. In this embodiment, an OLED display screen is used as the display screen of an electronic device. In the embodiment of the present application, the OLED display screen appears in the form of a display unit array, including a plurality of display units, each of which is a pixel unit of the OLED display screen, and can actively emit light, thereby realizing the display of display content.

[0058] It can be understood that, unlike the solution in the related art where the camera device is disposed above the display screen, the embodiment of the present application is a solution where the camera device is disposed inside the electronic device. Figure 3 .like Figure 3 As shown, the electronic device includes a display screen, a lens unit array, a photosensitive chip, a circuit board and a support component (holder). The display screen is specifically an OLED display screen; the photosensitive chip is provided with a photosensitive unit array. Figure 3From the longitudinal direction shown, it is mainly divided into the following layers: the first layer is the OLED display layer; the second layer is the lens unit array layer, which is arranged below the screen layer; the third layer is the circuit board (PCB) layer, on which at least a photosensitive chip is arranged, and the photosensitive chip is arranged below the lens unit array layer. This layer arrangement, on the one hand, realizes the scheme of setting the camera device such as the lens under the display screen, and on the other hand, the arrangement between the layers can ensure the normal realization of each function. Among them, the PCB layer and the OLED display layer are arranged in parallel and spaced apart, and the lens unit array layer and the photosensitive chip layer are accommodated in the space formed by the PCB layer and the OLED display layer being arranged in parallel and spaced apart, so that the space is effectively utilized. In addition, since each lens in the lens unit array in the embodiment of the present application adopts a micro lens, which occupies a small volume itself, and the photosensitive chip is arranged on the PCB, the problem of increasing the thickness of the electronic device caused by the camera device being arranged inside the electronic device can be effectively avoided. The number of holders is two, which are used to support the PCB layer and the OLED display layer arranged in parallel and spaced apart to achieve the fixation of the PCB and the OLED display screen.

[0059] In the present application embodiment, Figure 4 The lens unit array shown in FIG. 5 and the photosensitive unit array shown in FIG. 5( a) and ( b) are taken as examples. Figure 4 As shown in FIG. 5 , the lens unit array includes M*N=3*3, a total of 9 lenses, where M and N are both positive integers. Each lens is a micro lens. A micro lens corresponds to multiple photosensitive units, such as hundreds or thousands of photosensitive units. FIG. 5( a ) is a schematic diagram of a photosensitive unit group corresponding to a micro lens. FIG. 5( b ) is a schematic diagram of a photosensitive unit group corresponding to a micro lens. Figure 4 Schematic diagram of the photosensitive unit array corresponding to the 9 micro lenses shown; in Figure 5(a) and Figure 5(b), a small grid represents a photosensitive unit, and a group of photosensitive units starting with an R is a photosensitive unit group, corresponding to a micro lens.

[0060] In the embodiment of the present application, 12 adjacent display units located in the center area of ​​the OLED display screen are selected from all the display units in the display unit array, and the 12 adjacent display units appear in a 3*4 array. Figure 6As shown, a circle represents a display unit, a wrong number represents a micro lens, and a quadrilateral represents a photosensitive unit group. In the embodiment of the present application, the first micro lens among the 9 micro lenses is set below the gap between the two adjacent display units in the 1st row, 1st column and 2nd column of the 3*4 display unit array, and the photosensitive unit group corresponding to the first micro lens is set below the first micro lens; the second micro lens is set below the gap between the two adjacent display units in the 1st row, 2nd column and 3rd column of the 3*4 display unit array, and the photosensitive unit group corresponding to the second micro lens is set below the second micro lens; the third micro lens is set below the gap between the two adjacent display units in the 1st row, 3rd column and 4th column of the 3*4 display unit array, and the photosensitive unit group corresponding to the third micro lens is set below the third micro lens; and so on, the corresponding settings of the micro lenses and photosensitive unit groups inside the electronic device are completed. It can be understood that Figure 6 This is just a schematic diagram as an example. In actual design, the gaps between display units, micro lenses and photosensitive unit groups are very small.

[0061] From the above solution, it can be seen that the method of arranging each micro lens below the gap between each two adjacent display units in the embodiment of the present application fully utilizes the gap space between the display units and reduces the space occupied. In addition, the gap between the display units is just enough to transmit light and will not affect the normal collection of light by the lens.

[0062] Take the camera device set in a smart phone as an example. When the electronic device receives a command to start the camera function, each micro lens collects the light passing through the gap between the corresponding display units for the current scene, and obtains the light signals collected by each micro lens. Taking the first micro lens as an example, the light reaches the lens of the micro lens through the gap between the display units of the first row, the first column and the second column. The light passes through the lens and passes through the red, green and blue (RGB) filter of the micro lens, filtering out other colors from the collected light signal. Figure 7As shown in the working principle, the red filter of the micro lens is used to filter out other colors and retain red, the green filter of the micro lens is used to filter out other colors and retain green; the blue filter of the micro lens is used to filter out other colors and retain blue. The red, green and blue (RGB) filter transmits the retained light signals of each color to the photosensitive unit group 1 corresponding to the first micro lens. During the transmission process, there will be dispersion of the light signal. The photosensitive unit group 1 deletes the scattered light, converts the light signal into an electrical signal, calculates the intensity of the three-color electrical signal, and obtains a small image calculated based on the light signal collected by the first micro lens. Each micro lens collects light from the same scene at the same time, and processes it as above based on the photosensitive unit group corresponding to itself to obtain each small image. The image stitching technology is used to stitch each small image to obtain the image finally captured by the camera device. Among them, it can be understood that in each small image, it is determined whether there is the same photographed object in at least two small images. For the same photographed object, the shooting attributes such as clarity higher than the predetermined attribute threshold or the image part with the highest clarity are selected as the final photographed image (target small image) of the same photographed object, and the target small images for the same photographed object selected from each small image and the different parts in each small image are spliced ​​to obtain the image finally captured by the camera device. Thereby, the normal shooting of the camera device is achieved. For the specific process of splicing each small image using image stitching technology to obtain the final captured image, please refer to the existing relevant description, which will not be repeated. The attribute threshold is any reasonable value or value range set in advance.

[0063] It can be seen from the above scheme that the lens of the camera device in the embodiment of the present application is composed of multiple lenses, and the photosensitive unit is composed of multiple photosensitive units. From the perspective of the photosensitive unit, the embodiment of the present application adopts a photosensitive unit array, and the increase in the number of photosensitive units will bring about the beneficial effect of improving the resolution of the captured image. From the perspective of the lens, the increase in the lens will bring about the beneficial effect of increasing the image pixels; for example, taking the pixel of a micro lens as 1 million as an example, the pixel of the image obtained by all the micro lenses is 9*100=9 million pixels, the image pixels are increased, and the image display is clearer. It can be seen that the embodiment of the present application can obtain an image with higher image pixels through the setting of multiple lenses, and the user's visual experience will be greatly improved.

[0064] The electronic device provided in each embodiment of the present application has a camera lens array disposed below the display screen (i.e., the display screen covers the camera lens), and the camera lens array uses the light incident from the gaps between the display units (i.e., pixel units) of the display screen to form a captured image, wherein the camera lens array is staggered with the display units of the display screen (i.e., facing the gaps between the display pixels). In order to reduce the influence of the display unit light emission on the camera captured image during the image capture process of the camera in the working state, the first pixel unit (i.e., the pixel unit around the gap corresponding to a lens) corresponding to the camera lens array in the display screen is turned off or adjusted to display black in each embodiment of the present application.

[0065] An electronic device provided according to an embodiment of the present application has a gap between first pixel units in a display screen of the electronic device corresponding to the lens array of the camera that is larger than a gap between second pixel units in the display screen that do not correspond to the lens array of the camera.
