The display device 200 can be a liquid crystal display (Liquid Crystal Display, LCD) or an organic light-emitting diode display (Organic Light-Emitting Diode, OLED).

The electronic device 20 may further include a light-transmitting area 300, and the light-transmitting area 300 may be used for light signals from outside the electronic device 20 to be injected into the electronic device 20. The light-transmitting 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 area 300 may be a regular structure, such as a circle, a rectangle, or an irregular structure.

The light-transmitting area 300 may be provided on the display device 200, so that the light signal located on the side of the display device 200 can be injected into the electronic device 20 through the light-transmitting area 300, and the camera located inside the electronic device 20 can receive the incident light signal and collect it. An image located on the side of the display device 200. It can be understood that when the light-transmitting area 300 is provided on the display device 200, the camera is equivalent to the front camera of the electronic device 20.

It should be noted that when the light-transmitting area 300 is disposed on the display device 200, the light-transmitting area 300 may be located in a non-display area, such as setting the light-transmitting area in the non-display area of the display device 200 to form the light-transmitting area 300. It is understandable that the display device 200 may include a cover 240 and a display 220. The cover 240 is arranged on the display 220 to protect it, and the light-transmitting area 300 may also be arranged on the cover of the display device 200. , But not set on the display 220. The light-transmitting area 300 may also be disposed in the display area of the display screen 220, such as dividing the display screen 220 into at least two areas, such as a light-transmitting display area and a main display area.

As shown in FIG. 2, FIG. 2 is a first cross-sectional view of the electronic device shown in FIG. 1 along the P-P direction. The electronic device 20 may also include a prism such as a prism group 400. The prism group 400 may be installed inside the electronic device 20 and arranged opposite to the light-transmitting area 300. The prism group 400 can be used to process the incident light signal to change the optical path of the incident light signal. The prism group 400 may include at least one prism, and the prism may have a regular structure. For example, the prism group 400 may include a triangular prism, the triangular prism may include five surfaces, and the five surfaces may perform different processing on the incident light signal. The prism can also have an irregular structure.

For example, the prism group 400 may include a first dichroic surface 410, and the first dichroic surface 410 may be formed by coating one surface of the prism group 400 or other special treatments. The first dichroic surface 410 may be arranged opposite to the light-transmitting area 300, so that the incident light signal can be injected into the first light-splitting surface 410. For example, the first light-splitting surface 410 may overlap the light-transmitting area 300 in a vertical space, so that the optical signal can be It is incident on the first dichroic surface 410 from the light-transmitting area 300. In other words, the first dichroic surface 410 may be arranged on the transmission path of the optical signal.

The first light splitting surface 410 may be used to perform light splitting processing on the incident light signal incident on the first light splitting surface 410 to form a first reflected light signal and a first transmitted light signal. It can be understood that after the incident light signal is incident on the first dichroic surface 410, part of the incident light signal is reflected on the first dichroic surface 410 to form a first reflected light signal, and part of the incident light signal is transmitted on the first dichroic surface 410. To form a first transmitted light signal. The first dichroic surface 410 may be a semi-reflective and translucent surface, that is, half of the incident light signal incident on the first dichroic surface 410 is reflected, and the other half of the incident light signal incident on the first dichroic surface 410 is reflected. Transmission occurs so that the energy of the first reflected light signal and the first transmitted light signal are equivalent.

In some embodiments, a first spectroscopic film (also called a first semi-reflective semi-transparent film) may be plated on the first spectroscopic surface 410, and the first spectroscopic 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 spectroscopic film may be one or more of wavelength spectroscopic film, light intensity spectroscopic film and polarization spectroscopic film.

The prism group 400 may further include a second dichroic surface 420, and the second dichroic surface 420 may be formed by coating the other surface of the prism group 400 or other special treatments. The second light-splitting surface 420 is arranged away from the light-transmitting area 300, so that the incident light signal cannot directly enter the second light-splitting surface 420. The second dichroic surface 420 is disposed opposite to the first dichroic surface 410. For example, the second dichroic surface 420 can be arranged corresponding to the transmission path of the first transmitted light signal, so that part or all of the first transmitted light signal can be incident on the second dichroic surface 420 . The second dichroic surface 420 may perform reflection processing on at least a part of the first transmitted light signal incident on the second dichroic surface 420 to form a second reflected light signal. For example, the second dichroic surface 420 may perform reflection processing on at least a part of the first transmitted light signal incident on the second dichroic surface 420. A part of the first transmitted light signal in 420 is processed, and all the first transmitted light signals incident on the second beam splitting surface 420 may also be processed, such as all reflection processing. It can be understood that, after the first transmitted light signal is incident on the second dichroic surface 420, it is reflected on the second dichroic surface 420 to form the second reflected light signal. It should be noted that when the second reflected light signal is emitted from the inside of the prism group 400 to the outside of the prism group 400, the second reflected light signal is refracted inside the prism group, so that the second reflected light signal goes from the second light splitting surface to the exit surface. The transmission path is inclined, and the specific inclination angle is determined by the structure of the prism group 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 light signal incident on the first camera 620 can be increased by adjusting the relationship between the first dichroic surface 410 and the first camera 620. For example, the first dichroic surface 410 can be directed toward the first camera 620. A camera 620 is arranged obliquely, so that the incident light signal incident on the first light splitting surface 410 is more reflected to the first camera 620, and the incident light signal directly incident on the second camera 640 can also be reduced. Among them, the inclination angle may be 135 degrees, 130 degrees, 120 degrees, 110 degrees, and so on. The inclination angle of the first dichroic surface 410 refers to the angle formed from the first dichroic surface 410 toward the first camera 620.

In addition, the relationship between the second dichroic surface 420 and the second camera 640 can be adjusted at the same time to increase the second reflected light signal incident on the second camera 640. For example, the second dichroic surface 420 can be tilted toward the second camera 640. , So that the first transmitted light signal incident on the second dichroic surface 420 is more reflected to the second camera 640, and the inclination angle can be 135 degrees, 130 degrees, 120 degrees, 110 degrees, and so on. The inclination angle of the second dichroic surface 420 refers to the angle formed from the second dichroic surface 420 toward the second camera 640. Moreover, the projection of the second dichroic surface 420 on the electronic device 20 in the embodiment of the present application overlaps with the projection of the first dichroic surface 620 on the electronic device 20. It can be understood that the central axis of the first dichroic surface 410 overlaps with the central axis of the second dichroic surface 420. In this way, the first transmitted light signal can be more incident to the second light splitting surface 420.

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

It should be noted that a second spectroscopic film (also called a second semi-reflective semi-transparent film) can also be plated on the second spectroscopic surface 420. The second spectroscopic film can adjust the optical signal intensity of the second reflected optical signal, thereby increasing the The light splitting effect of the dichroic surface 420. The second spectroscopic film may be one or more of a wavelength spectroscopic film, a light intensity spectroscopic film, and a polarization spectroscopic film. The second spectroscopic film may be the same as the first spectroscopic film or different.

Enter the first camera 620.

The second camera 640 may be arranged on the other side of the prism group 400, away from the first dichroic surface 410, and the second camera 640 may be used 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 arranged adjacent to the second dichroic surface 420 and located on the reflected light signal transmission path of the second dichroic surface 420, so that the first transmitted light signal incident on the second dichroic surface 420 is reflected and formed The second reflected light signal can be injected into the second camera 640.

Wherein, the first camera 620 may be used as the main camera of the electronic device 20 and is mainly used for taking pictures. For example, the first camera 620 is an RGB image acquisition camera.
