Detailed Description

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 20 may be a computing device such as a laptop computer, a computer monitor containing an embedded computer, a tablet computer, a cellular telephone, a media player, or other handheld or portable electronic devices, smaller devices (such as a wristwatch device, a hanging device, a headset or earpiece device, a device embedded in eyeglasses, or other device worn on the head of a user, or other wearable or miniature devices), a television, a computer display not containing an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or automobile), a device that implements the functionality of two or more of these devices, or other electronic devices. In the exemplary configuration of fig. 1, the electronic device 20 is a portable device, such as a cellular telephone, media player, tablet, or other portable computing device. Other configurations may be used for the electronic device 20, if desired. The example of fig. 1 is merely exemplary.

As shown in fig. 1, the electronic device 20 includes a display device such as the display device 200. The display device 200 may be mounted on a housing of the electronic apparatus, and the display device 200 is used to form a display surface of the electronic apparatus 20 for displaying information such as images and texts. The Display device 200 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED) Display.

The electronic device 20 may further include a light-transmissive region 300, and the light-transmissive region 300 may be used to allow light signals external to the electronic device 20 to be incident into the electronic device 20. The transparent area 300 may be a through hole, or a window formed by covering a transparent substrate on the through hole, for example, a transparent glass plate or a transparent plastic plate may be covered on the through hole, or a transparent structure, such as transparent glass. The optical signal can penetrate into the electronic device 20 through the light-transmitting area 300 to form an incident optical signal. The shape of the light-transmitting region 300 may be regular, such as circular, rectangular, or irregular.

The light-transmitting region 300 may be disposed on the display device 200, so that an optical signal at one side of the display device 200 may be incident into the electronic apparatus 20 through the light-transmitting region 300, and a camera at the inside of the electronic apparatus 20 may receive the incident optical signal and capture an image at one side of the display device 200. It is understood that when the light-transmissive area 300 is disposed on the display device 200, the camera corresponds to a front camera of the electronic apparatus 20.

It should be noted that when the light-transmitting region 300 is disposed on the display device 200, the light-transmitting region 300 may be located in the non-display region, such as the light-transmitting region 300 formed by disposing the light-transmitting region in the non-display region of the display device 200. It is understood that the display device 200 may include a cover 240 and the display screen 220, the cover 240 is disposed on the display screen 220 to protect the display screen, and the light-transmitting region 300 may be disposed on the cover of the display device 200 instead of the display screen 220. The light-transmissive region 300 may also be disposed in a display area of the display screen 220, such as dividing the display screen 220 into at least two regions, such as a light-transmissive display region and a main display region, the light-transmissive display region being the light-transmissive region 300. The light transmittance of the light-transmitting display region may be set to be larger than that of the main display screen region, such as sparsely arranging pixels of the light-transmitting display region, or arranging pixels of the light-transmitting display region to be larger in size than pixels of the main display region, or connecting the pixels of the light-transmitting display region in parallel and driving by one driving unit to reduce the number of driving signal lines and driving units. Of course, at least a part of the circuits of the driving unit for driving the light-transmissive display region may be disposed outside the light-transmissive display region, such as at the main display region or the side of the display device 200. The manner of increasing the transmittance of the light-transmitting display region is not limited to this, and for example, no polarizer or the like is provided in the light-transmitting display region.

One light transmission area 300 can be used for a plurality of cameras to take pictures, and the size of the light transmission area 300 can be set to correspond to the size of a lens of one camera. Compared with the prior art, one camera is provided with one light transmission area or a plurality of cameras are provided with one light transmission area corresponding to the size of the plurality of cameras, the number of the light transmission areas can be reduced or the size of the light transmission areas can be reduced.

Referring to fig. 2, fig. 2 is a first cross-sectional view of the electronic device shown in fig. 1 along a P-P direction. The electronics 20 may also include a prism such as prism assembly 400. The prism assembly 400 may be installed inside the electronic device 20 and disposed opposite to the light-transmitting region 300. Prism assembly 400 can be used to process the incident optical signal to change the optical path of the incident optical signal. The prism assembly 400 may include at least one prism, and the prism may have a regular structure. For example, prism assembly 400 may include a prism that includes five surfaces that may be configured to process incident optical signals differently. The prisms may also be irregular structures.

For example, the prism assembly 400 may include a first light-splitting surface 410, and the first light-splitting surface 410 may be formed by performing a plating process or other special process on one surface of the prism assembly 400. The first light-splitting surface 410 may be disposed opposite to the light-transmitting area 300 so that an incident light signal may be incident on the first light-splitting surface 410, for example, the first light-splitting surface 410 may vertically spatially overlap with the light-transmitting area 300 so that an optical signal may be incident on the first light-splitting surface 410 from the light-transmitting area 300. Or the first light splitting plane 410 may be disposed on a transmission path of the optical signal.

The first light splitting plane 410 may be used to split an incident light signal incident on the first light splitting plane 410 to form a first reflected light signal and a first transmitted light signal. It is understood that after the incident light signal is incident on the first light splitting surface 410, a portion of the incident light signal is reflected at the first light splitting surface 410 to form a first reflected light signal, and a portion of the incident light signal is transmitted at the first light splitting surface 410 to form a first transmitted light signal. The first light splitting surface 410 may be a semi-reflective and semi-transparent surface, that is, half of the incident light signal entering the first light splitting surface 410 is reflected, and the other half of the incident light signal entering the first light splitting surface 410 is transmitted, so that the energy of the first reflected light signal is equivalent to that of the first transmitted light signal.

In some embodiments, the first light splitting surface 410 may be coated with a first light splitting film (also referred to as a first semi-opaque film), and the first light splitting film may balance the energy of the first reflected light signal and the first transmitted light signal, thereby improving the light splitting effect of the first light splitting surface 410. The light splitting film can be one or more of a wavelength light splitting film, a light intensity light splitting film and a polarization light splitting film.

The prism assembly 400 may further include a second light-splitting surface 420, and the second light-splitting surface 420 may be formed by performing a plating process or other special process on another surface of the prism assembly 400. The second light-splitting surface 420 is disposed away from the light-transmitting region 300, so that the incident light signal cannot directly enter the second light-splitting surface 420. The second light splitting surface 420 is disposed opposite to the first light splitting surface 410, for example, the second light splitting surface 420 may be disposed corresponding to a transmission path of the first transmission light signal, so that part or all of the first transmission light signal can be transmitted into the second light splitting surface 420. The second light splitting surface 420 may perform a reflection process on at least a portion of the first transmitted light signal incident on the second light splitting surface 420 to form a second reflected light signal, for example, the second light splitting surface 420 may perform a reflection process on a portion of the first transmitted light signal incident on the second light splitting surface 420, or may perform a reflection process on all of the first transmitted light signal incident on the second light splitting surface 420, for example. It will be appreciated that the first transmitted optical signal is incident on the second beam splitter 420 and is reflected at the second beam splitter 420 to form the second reflected optical signal. It should be noted that, when the second reflected light signal is emitted from the interior of the prism assembly 400 to the exterior of the prism assembly 400, the second reflected light signal is refracted in the interior of the prism assembly, so that the transmission path of the second reflected light signal from the second light splitting surface to the emitting surface is inclined, and the specific inclination angle is determined by the structure of the prism assembly 400 itself, which is not limited in the embodiment of the present application.

Since the optical signal is transmitted along a straight line, the first reflected optical signal entering the first camera 620 may be increased by adjusting the relationship between the first light splitting plane 410 and the first camera 620, for example, the first light splitting plane 410 may be inclined toward the first camera 620, so that the incident optical signal entering the first light splitting plane 410 is reflected more to the first camera 620, and the incident optical signal directly entering the second camera 640 may also be reduced. The inclination angle may be 135 degrees, 130 degrees, 120 degrees, 110 degrees, etc. The inclination angle of the first light splitting plane 410 refers to an angle formed from the first light splitting plane 410 toward the first camera 620.

Furthermore, the relationship between the second light-splitting surface 420 and the second camera 640 may be adjusted to increase the second reflected light signal entering the second camera 640, for example, the second light-splitting surface 420 may be disposed to be inclined toward the second camera 640, so that the first transmitted light signal entering the second light-splitting surface 420 is reflected into the second camera 640 more, and the inclination angle may be 135 degrees, 130 degrees, 120 degrees, 110 degrees, and the like. The inclination angle of the second light-splitting surface 420 refers to an angle formed from the second light-splitting surface 420 toward the second camera 640. Moreover, the projection of the second light splitting plane 420 on the electronic device 20 in the embodiment of the present application overlaps with the projection of the first light splitting plane 620 on the electronic device 20. It will be appreciated that the central axis of the first beam splitter 410 overlaps the central axis of the second beam splitter 420. This allows more of the first transmitted light signal to be injected into the second beam splitter 420.

In some embodiments, the second light-splitting surface 420 may be coated with a reflective film (also referred to as an anti-reflection film), which may increase the reflectivity of the second light-splitting surface 420, thereby increasing the intensity of the second reflected light signal. The reflective film may be a metallic reflective film and/or an all dielectric reflective film. For example, the entire area of the second light-splitting surface 420 may be coated with the reflection-increasing film, or at least a part of the area of the second light-splitting surface 420 may be coated with the reflection-increasing film.

The second light splitting surface 420 may be coated with a second light splitting film (also referred to as a second transflective film), and the second light splitting film may adjust the optical signal intensity of the second reflected optical signal, thereby improving the light splitting effect of the second light splitting surface 420. The second beam splitting film can be one or more of a wavelength beam splitting film, a light intensity beam splitting film and a polarization beam splitting film, wherein the second beam splitting film can be the same as or different from the first beam splitting film.

Referring to fig. 2, the electronic device 20 may further include at least two cameras, and the at least two cameras may cooperate to achieve a plurality of photographing functions. The plurality of cameras may be disposed around the prism group 400, and the prism group 400 may process the incident light signal, so that the incident light signal may be converted into a reflected light signal, a transmitted light signal, or a refracted light signal, and transmitted to each camera, and each camera may image based on the received light signal, so as to implement the photographing function of the electronic device 20.

For example, electronic device 20 may include a first camera 620 and a second camera 640. The first camera 620 and the second camera 640 may be used to capture images, implementing the capture function of the electronic device 20.

The first camera 620 may be disposed at one side of the prism assembly 400, and the first camera 620 may receive the first reflected light signal and form an image based on the first reflected light signal. For example, the first camera 620 may be disposed adjacent to the first light splitting surface 410 and located on a transmission path of the reflected light signal of the first light splitting surface 410, so that the first reflected light signal formed by reflection on the first light splitting surface 410 may be incident on the first camera 620.

The second camera 640 may be disposed on the other side of the prism assembly 400, away from the first light splitting plane 410, and the second camera 640 may be configured to receive the second reflected light signal and form an image based on the second reflected light signal. For example, the second camera 640 may be disposed adjacent to the second light splitting surface 420 and located on the transmission path of the reflected light signal of the second light splitting surface 420, so that the second reflected light signal formed by reflecting the first transmitted light signal incident on the second light splitting surface 420 can be incident on the second camera 640.

The first camera 620 may be a main camera of the electronic device 20, and is mainly used for taking pictures, such as the first camera 620 being an RGB image capturing camera. The second camera 640 may be a blurring camera of the electronic device 20, which may perform blurring processing or blurring processing on the content in the image captured by the first camera 620, and the pixels of the second camera 640 may be lower than those of the first camera 620. It should be noted that the functions of the first camera 620 and the second camera 640 are not limited to this, and for example, the first camera 620 may also be a blurring camera, and the second camera 640 may be a main camera, etc.

This application embodiment sets up with prism group 400 relatively through light zone 300, and prism group 400 can handle the incident light signal who jets into electronic equipment 20 through the light zone to the incident light signal transmission after will handling is to first camera 620 and second camera 640 in, can realize setting up a light zone and shoot for two cameras, and then saves the space occupation of light zone 300 to display device 200. The user can realize the function of leading two shootings through the printing opacity district, and the effect of shooing of leading camera can be improved for leading single shooting of prior art.

As shown in fig. 3, fig. 3 is a schematic view of a second structure of an electronic device according to an embodiment of the present application. The light transmissive region 300 may also be disposed on a housing of the electronic device 20, such as the housing 800. The housing 800 may be formed from plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The shell 800 may be formed using a one-piece configuration in which some or all of the shell 800 is machined or molded as a single structure, or may be formed using multiple structures (e.g., an inner frame structure, one or more structures that form an outer shell surface, etc.). The housing 800 may serve as a carrier for the electronic device 20 and may carry components of the electronic device 20.

The housing 800 may also include a back cover 840, and the back cover 840 may be used to form an outer contour of the electronic device 20. The rear cover 840 may be integrally formed. In the forming process of the rear cover 840, structures such as a microphone hole, a speaker hole, a receiver hole, an earphone hole, a USB interface hole, a rear camera hole, a fingerprint identification module mounting hole, and the like can be formed on the rear cover 840. The rear cover 840 may be interconnected with the display device 200 and cover the outside of other devices (e.g., a battery, a circuit board) on the case 800 to shield the other devices.

In some embodiments, the light-transmitting area 300 may also be disposed on the back cover 840, and the first camera 620 and the second camera 640 may be used as a rear camera of the electronic device 20, through which a user may take a rear shot. For example, a light hole may be formed in the back cover 840, and the light hole may serve as the light-transmitting area 300, or a light-transmitting lens may be disposed on the light hole. For a plurality of light traps that need be seted up to a plurality of cameras among the correlation technique, the shooting function that can realize a plurality of cameras can be seted up a light trap in this application embodiment at back lid 840, can save the occupation of light trap 300 to back lid 840 space.

It should be noted that, the electronic device 20 may also be provided with two light-transmitting areas 300 at the same time, wherein one light-transmitting area 300 is provided on the display device 200, and one light-transmitting area is provided on the rear cover 840, so that the prism group 400 is used to realize front double-shot and rear double-shot, and at the same time, the number or size of the light-transmitting areas provided on the display device 200 and the rear cover is reduced.

Referring to fig. 4 and 5, fig. 4 is a second schematic structural diagram of a prism in the electronic device shown in fig. 2, and fig. 5 is a second cross-sectional view of the electronic device shown in fig. 1 along a P-P direction.

The first transmissive surface 430 may be disposed between the second camera 640 and the second light-splitting surface 420 such that the second reflected light signal may be transmitted through the first transmissive surface 430 to form a second transmitted light signal. The second camera 640 may be disposed at one side of the first transmission surface 430 such that a second transmitted light signal may be incident into the second camera 640, and the second camera 640 may form an image based on the second transmitted light signal.

The shading surface can be arranged opposite to the first camera 620 and the second camera 640, so that the shading surface can block optical signals in other directions from entering the first camera 620 and/or the second camera 640, interference of the optical signals in other directions on imaging of the first camera 620 and/or the second camera 640 is reduced, and imaging effect of the first camera 620 and/or the second camera 640 is improved.

The fourth camera 680 may function as a wide-angle camera of the electronic device 20, which may increase the shooting angle and content of the first camera 620. It should be noted that the functions of the first camera 620 and the fourth camera 680 may be interchanged. The functional roles of the third camera 660 and the second camera 640 may be interchanged.

The pixels of the camera for receiving the second reflected light signal and the second transmitted light signal or the third transmitted light signal may be about 200 ten thousand. Such as about 200 million pixels for the third camera 660 and about 200 million pixels for the second camera 640. The pixels of the camera for receiving the first reflected light signal and the third reflected light signal may be between 800 and 5000. Such as about 4800 million pixels for the first camera 620 and about 800 million pixels for the fourth camera 680.

The pixel size of each camera is not limited to this, and the above pixels of each camera are merely examples, and constitute a limitation on the pixels of each camera.

The electronic device 20 may further include a processor for functioning as a control center of the electronic device 20 and a memory for storing software programs and modules, and the processor may execute various functional applications and data processing by executing the computer programs and modules stored in the memory 402.

The processor can be electrically connected with the cameras and controls the cameras to acquire images based on optical signals processed by the prism group. For example, the processor may be electrically connected to the first camera 620, and the processor may be configured to control the first camera to perform image acquisition based on the first reflected light signal; the processor may be further electrically connected to the second camera 640, and the processor may be further configured to control the second camera 640 to perform image acquisition based on the second reflected light signal. Similarly, the processor may be electrically connected to the third camera 660, and the processor may be configured to control the third camera 660 to perform image acquisition based on the third transmitted light signal, or perform image acquisition based on the third transmitted light signal and the fifth transmitted light signal; the processor may be further electrically connected to the fourth camera 680, and the processor may be configured to control the fourth camera to perform image acquisition based on the third reflected light signal.

The processor may select a corresponding camera according to a scene to perform image acquisition, for example, when a user performs close-range shooting (for example, shooting a microspur image of a flower bud), the processor may control the third camera 660 to perform image acquisition; when the user performs a wide-angle photographing (e.g., photographing a landscape), the processor may control the fourth camera 680 to perform image capturing. The processor can also control a plurality of cameras to acquire images simultaneously, for example, when a user takes a portrait, the processor can control the first camera 620 and the second camera 640 to acquire images simultaneously, and process the images acquired by the first camera 620 and the second camera 640 to present clear images and blurred images of the portrait. It should be noted that the above is only an example, and does not constitute a limitation to the processor of the embodiment of the present application.
