[0002] Generally speaking, electronic devices with screens may be provided with sensors such as ambient light sensors or optical proximity sensors. The photosensitive devices of these sensors need to directly or indirectly receive light signals and sense the light signals, so the light cannot be blocked. Therefore, a light-transmitting opening may be provided on the display screen of the electronic device to allow the light signal to pass through, thereby realizing the detection of the light signal.

[0040] Figure 1A A schematic side view of an electronic device according to an embodiment of the present application. Figure 1B FIG. 1 is a schematic plan view of an electronic device according to another embodiment of the present application. Figure 1C FIG. 1 is a side view schematic diagram of an electronic device according to another embodiment of the present application. Figure 1A-Figure 1C As shown, the electronic equipment includes:
[0041] The camera module 110 , the display screen 120 and the photosensitive device 130 .
[0042] It should be understood that the display screen 120 herein includes but is not limited to a self-luminous display screen such as an organic light-emitting display screen (OLED) or a liquid crystal display screen (LCD), and the embodiments of the present application are not limited thereto.
[0043] The display screen 120 may include a light-transmitting cover plate 122, a light-emitting layer 124, and a black glue layer 126. Figure 1C As shown, the display screen 120 may be provided with a transparent cover plate 122, a light emitting layer 124 and a black glue layer 126 in order from top to bottom. The transparent cover plate 122 includes but is not limited to a glass cover plate, a cover plate formed of a polyimide (PI) material, and the like.
[0044] It should also be understood that the camera module (Camera Compact Module, CCM) 110 may include a lens, an imaging chip, a circuit board such as a flexible circuit board, and an image processing chip (or a signal processing unit).
[0045] It should also be understood that the photosensitive device 130 may include a photosensitive element, and the photosensitive element may have a photosensitive surface. The photosensitive device may also include other electronic components such as transistors, resistors, and capacitors. The photosensitive device may be used to form an ambient light sensor to detect ambient light signals, or may be used to form an optical proximity sensor to detect proximity, or may simultaneously detect ambient light signals and human proximity light signals.
[0046] The display screen 120 includes a light transmission port 121 . The camera module 110 includes a lens barrel 111 . The lens barrel 111 has a light inlet 112 , and the light inlet 112 can receive a first portion of light passing through the light transmission port 121 .
[0047] In one example, for a self-luminous display screen, an opening process can be performed on the opaque black glue layer of the display screen, and an opening or light-transmitting process can be performed on the light-emitting layer to form a light-transmitting opening. In another example, a liquid crystal display screen may include an opaque backlight module, and for a liquid crystal display screen, an opening can be set on the backlight module to form a light-transmitting opening.
[0048] The photosensitive device 130 is disposed on a side of the lens barrel 111 facing the display screen 120 .
[0049] The photosensitive device 130 includes a light-transmitting area 131 and a light-sensitive area 132 . The light-transmitting area 131 is used to allow a first portion of light passing through the light-transmitting port 121 to pass through and enter the light inlet 112 , and the light-sensitive area 132 is used to receive and sense a second portion of light passing through the light-transmitting port 121 .
[0050] Specifically, the lens barrel of the camera module 110 can be located below the display screen 120, and the lens barrel 111 of the camera module 110 is disposed below the opening of the black glue layer 126 below the light-transmitting cover plate 122. The photosensitive device 130 is located below the display screen 120 and above the camera module 110. In other words, the photosensitive device 130 is disposed above the lens barrel 111.
[0051] It should also be understood that the electrical signal generated by the photosensitive device in the present application needs to be processed by the signal processing unit. The signal processing unit can be located on the photosensitive device, or on the circuit board of the camera module, or on the main circuit board 140 of the electronic device. For example, the photosensitive device 130 is connected to the main circuit board 140 via the circuit board 150.
[0052] like Figure 1AAs shown, the lens barrel 111 has a light inlet 112. For example, the light inlet 112 may be defined by an inner wall of one end (upper end) of the lens barrel 111 facing the display screen 120. Figure 1B As shown, the camera module 110 is disposed below the light-transmitting opening of the display screen 120. Figure 1C As shown, external light can enter the light inlet 112 of the camera module 110 through the light-transmitting port 121, and then pass through the lens 118 set in the camera module 110 to reach the photoelectric converter 119 to generate an electrical signal. After being processed, the electrical signal is transmitted through the circuit board to realize the function of the camera module.
[0053] As an example, Figure 1C As shown, the photosensitive device 130 is located above the lens barrel 111 of the camera module 110, and the center of the photosensitive device 130 can be formed as a light-transmitting area. In this embodiment, the light-transmitting area corresponds to the light inlet 112 of the camera module 110. It should be understood that the light-transmitting area can be adapted to the light inlet of the camera module, or, defined by the size and shape of the light inlet, it can be any shape. The photosensitive area of the photosensitive device can be located at the periphery of the light-transmitting area and does not overlap with the light-transmitting area. As an example, the light-transmitting area can be circular, and the photosensitive area can be annular.
[0054] In the scheme of the embodiment of the present application, the first part of the light passing through the light-transmitting port can pass through and enter the light inlet, and the photosensitive area is used to receive and sense the second part of the light passing through the light-transmitting port. Therefore, the light-transmitting port corresponding to the camera module is used to realize effective sensing of external light, avoiding the need to set an opening for the display screen separately for the photosensitive device, thereby ensuring the continuity of the display screen.
[0055] In addition, the size of the lens barrel 111 can be smaller than the size of the light-transmitting port 121. The size of the lens barrel 111 can also be larger than the size of the light-transmitting port 121. Preferably, due to assembly requirements, the size of the light-transmitting port on the display screen is usually slightly larger than the area of the light inlet of the camera module, that is, the area of the light-transmitting port of the display screen can be larger than the area of the light inlet of the camera module, so that it can be ensured that light smoothly enters the camera module through the light inlet. However, if the light-transmitting port is too large, the screen-to-body ratio of the display screen will be affected. In the solution of the embodiment of the present application, since the photosensitive device is arranged on the side of the lens barrel facing the display screen, the light transmission range of the light-transmitting port of the display screen is fully utilized, avoiding sacrificing the screen-to-body ratio of the display screen due to the light-transmitting port of the display screen being set too large. In other words, the screen-to-body ratio of the display screen is guaranteed.
[0056] For example, when the photosensitive device is arranged around the lens barrel, if the effective sensing of external light is to be ensured, the light transmission port needs to be set larger. In the embodiment of the present application, the photosensitive device is arranged on the side of the lens barrel facing the display screen, and there is no need to specially set a larger light transmission port for the photosensitive device, thereby better ensuring the screen ratio of the display screen.
[0057] In one example, the light-transmitting port can be adapted to the outer edge of the lens barrel without setting the size of the light-transmitting port specifically for the photosensitive device. In other words, it is only necessary to set the light-transmitting port according to the size of the lens barrel of the camera module, thereby achieving backward compatibility with such display screens and maximizing the screen-to-body ratio of the display screen.
[0058] In addition, the photosensitive device is arranged on the side of the lens barrel facing the display screen, and the first part of the light passing through the light-transmitting port can pass through and enter the light inlet of the camera module. Therefore, this arrangement avoids the influence of the photosensitive device on the imaging of the camera module.
[0059] In addition, the photosensitive area is used to receive and sense the second part of the light that passes through the light-transmitting port, avoiding the influence of the light from the self-luminous layer of the display screen, thereby ensuring the light detection effect. For example, when the photosensitive device is used to detect ambient light, this setting method greatly reduces the influence of the screen's self-luminescence, preventing the photosensitive device from being unable to distinguish whether the received light is ambient light or the screen's self-luminescence, resulting in a large error in the ambient light detection result, thereby improving the accuracy of ambient light detection.
[0060] The light-transmitting area may not be a part of the photosensitive device entity. For example, the light-transmitting area may be a hollow area surrounded by the photosensitive area.
[0061] Specifically, if Figure 2A 2 is a schematic plan view of a photosensitive device provided in an embodiment of the present application. The photosensitive area of the photosensitive device 130 is annular, the inner side of the annular shape is the light inlet 112 (the inner wall of the lens barrel), and the outer side of the annular shape is the outer wall of the lens barrel 111. In the schematic plan view shown in FIG. 2 , a rectangular lens barrel base 113 of the lens barrel 111 is also shown.
[0062] In one example, when the photosensitive area is composed of an amorphous silicon photodiode (Light-Emitting Diode, LED) or an organic photodiode (Organic Light-Emitting Diode, OLED), a photosensitive device can be manufactured on a transparent substrate (for example, a glass substrate, a polyimide (PI) substrate, etc.) to form a photosensitive area, and the area where the photosensitive element or other elements are not manufactured is used as a light-transmitting area.
[0063] In another example, when the photosensitive region is composed of a single crystal silicon photodiode, it can be directly fabricated on a single crystal silicon substrate to form a photosensitive device. For example, a process such as etching or laser cutting can be used to dig out a portion of the region to form a light-transmitting region, and the remaining region not dug out is used as the photosensitive region.
[0064] As an example, the light-transmitting area is circular, and the light-sensitive area is annular. Since the light-transmitting area is circular and the light-sensitive area is annular, it matches the shape of the light inlet of the lens barrel, and does not affect the light received by the light inlet of the lens barrel, thereby not affecting the imaging of the camera module. Figure 2B Schematic diagram of the photosensitive device of this example is shown. Figure 2B As shown, the photosensitive device 130 includes a photosensitive region 131 and a light-transmitting region 132, and is connected to a circuit board 250. In one example, the circuit board 250 may be a flexible circuit board.
[0065] In another implementation of the present application, the photosensitive area surrounds the light-transmitting area, and the inner edge of the photosensitive area coincides with the outer edge of the light-transmitting area. Such a setting can well ensure that the first part of the light can be incident on the light inlet of the camera module through the light-transmitting area of the photosensitive device, without affecting the imaging of the camera module.
[0066] In another implementation of the present application, the outer edge of the photosensitive area coincides with the outer edge of the lens barrel. Such a setting does not affect the imaging of the camera module, nor does it need to enlarge the size of the light-transmitting port in order to enable the photosensitive device to fully receive the light signal passing through the light-transmitting port of the display screen, which is conducive to increasing the screen-to-body ratio.
[0067] In another implementation of the present application, the photosensitive area includes a plurality of filter areas alternately arranged along the periphery of the light-transmitting area, and adjacent filter areas among the plurality of filter areas have different filter bands.
[0068] Specifically, the photosensitive device in the electronic device of the present application is used to detect light from the outside that passes through the cover plate. For example, it can be ambient light. The photosensitive device can convert the incident ambient light into an electrical signal, and further calculate the intensity of the ambient light. Furthermore, the photosensitive device can be divided into multiple areas, and different areas are covered with different filters.
[0069] In another implementation of the present application, the different filtering bands include three visible light bands. Specifically, the filtering area can be implemented as a filter. As an example, a photosensitive device can be covered with three monochromatic filters of red (R), green (G) and blue (B). The signals generated by the photosensitive devices under different monochromatic filters can be used to provide color temperature information of the ambient light source. Figure 2CA schematic diagram of the photosensitive area for this example is shown.
[0070] In addition, different filtering bands may include visible light bands and infrared bands to improve the reliability of visible light bands and infrared bands. Specifically, the photosensitive device may be covered with a visible light filter and an infrared filter. For example, the infrared filter can transmit 940nm light, so that the photosensitive device can detect infrared light signals emitted by electronic devices. Furthermore, the visible light signal transmitted through the visible light filter can be used to realize ambient light detection, and the infrared light signal transmitted through the infrared filter can be used to judge the proximity signal of the human body, and can also be used to judge the gesture change signal of the human body. Figure 2D A schematic diagram of the photosensitive area for this example is shown.
[0071] In another implementation of the present application, the light-transmitting area is circular, and the light-sensitive area is located at the connection position between the rectangular circuit board of the light-sensitive device and the light-sensitive device. This arrangement makes the light-sensitive area effectively utilize the space and improves the detection reliability of the light-sensitive area.
[0072] Figure 3A Schematic diagram of the photosensitive region of this example is shown. As shown in the figure, the photosensitive device 130 includes a photosensitive region 131 and a light-transmitting region 132, and is connected to a flexible circuit board 350. Figure 3B A schematic side view of an electronic device of this example is shown.
[0073] In another implementation of the present application, the photosensitive device is electrically connected to the main circuit board of the electronic device through the first flexible circuit board. Such a wiring method improves the flexibility of the positional relationship between the photosensitive device and the main circuit board.
[0074] In another implementation of the present application, the camera module is electrically connected to the main circuit board of the electronic device through the second flexible circuit board. Such a wiring method improves the flexibility of the positional relationship between the camera module and the main circuit board.
[0075] In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module. Such a wiring method eliminates the need to change the wiring between the circuit board of the camera module and the main circuit board, thereby reducing the difficulty of wiring.
[0076] In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module via a flexible circuit board. Such a wiring method improves the flexibility of the positional relationship between the camera module and the photosensitive device.
[0077] In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module through internal wiring of the barrel wall of the lens barrel. Such a wiring method reduces the space occupied by the wiring in the electronic device.
[0078] In another implementation of the present application, the internal wiring is formed in the barrel wall via a heterogeneous multi-material injection molding process, which improves the reliability of the wiring.
[0079] In another implementation of the present application, the display screen is provided with a light-emitting layer, wherein the light-emitting layer has a first opening forming a light-transmitting opening. Such a configuration effectively avoids the light-emitting layer from blocking external light.
[0080] In another implementation of the present application, the display screen is provided with a light-emitting layer, the light-emitting layer includes a first light-emitting area and a second light-emitting area, the transmittance of the first light-emitting area is less than the transmittance of the second light-emitting area, and the second light-emitting area is used to form a light-transmitting port.
[0081] Since the transmittance of the first light emitting area is lower than that of the second light emitting area, the light emitting layer is effectively prevented from blocking external light, and since the second light emitting area also has a display function, the display effect of the display screen is guaranteed.
[0082] In another implementation of the present application, the display screen is provided with a black glue layer, wherein the black glue layer has a second opening forming a light-transmitting opening. Such a configuration effectively avoids the black glue layer from blocking external light.
[0083] In another implementation of the present application, a portion of the photosensitive device is blocked by the non-opening portion of the black glue layer. In other words, a portion of the photosensitive area senses the first portion of light through the second opening, and another portion of the photosensitive area is blocked by the non-opening portion outside the second opening of the black glue layer.
[0084] Since a part of the photosensitive area senses the first part of the light through the second opening, and another part of the photosensitive area is blocked by the non-opening part of the black glue layer, the space corresponding to the light-transmitting area is fully utilized to increase the area of the photosensitive area.
[0085] Figure 4 A schematic diagram showing a connection method of a flexible printed circuit board according to another embodiment is shown. Figure 4 Electronic equipment includes:
[0086] Display screen 420 , camera module 410 and photosensitive device 430 .
[0087] The camera module 410 includes a lens barrel 411 , and a light inlet 412 of the lens barrel is used to receive a first portion of light passing through a light-transmitting opening 421 of a display screen 420 .
[0088] The photosensitive device 430 is disposed on a side of the lens barrel 411 facing the display screen 420 , and is used for sensing the second portion of light passing through the light transmission opening 421 .
[0089] like Figure 4 As shown, the photosensitive device 430 can be electrically connected to the main circuit board 440 through the first flexible circuit board, and the circuit board of the camera module can be electrically connected to the main circuit board 440 through the second flexible circuit board. In other words, the electrical signal generated by the photosensitive device is directly connected to the main circuit board of the electronic device through a flexible circuit board. The electrical signal of the camera module is connected to the other side of the main circuit board through another flexible circuit board.
[0090] In addition, the photosensitive device in the embodiment of the present application can realize ambient light detection or infrared optical proximity sensing. Figure 4 As shown, in this example, the electronic device includes a display screen 420 and a back plate 490. The display screen 420 may include a transparent cover plate 422, a light-emitting layer 424, and a black glue layer 426. A small hole may be provided near the frame 480 of the electronic device. A light-guiding structure 460 is provided in the small hole. The electronic device also has an infrared light source 470 that emits 940nm light. The light-guiding structure 460 is used to guide the infrared light in the infrared light source out of the transparent cover plate 422. An infrared filter and at least one visible light filter may be provided on the photosensitive device at the same time. The infrared light emitted by the infrared light source can be received by the photosensitive device after being emitted by the human body.
[0091] In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module via a flexible circuit board. Such a wiring method improves the flexibility of the positional relationship between the camera module and the photosensitive device.
[0092] Specifically, the flexible circuit board can transmit the electrical signal generated by the photosensitive device to the circuit board of the camera module. Figure 5A The schematic diagram of the connection mode of the flexible circuit board of this example is shown. As shown in the figure, the photosensitive device 430 is connected to the circuit board of the camera module through the flexible circuit board 551.
[0093] In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module through internal wiring of the barrel wall of the lens barrel. Such a wiring method reduces the space occupied by the wiring in the electronic device.
[0094] Specifically, in the process of manufacturing the lens barrel of the camera module, some metal wires running through the lens barrel are manufactured. For example, the manufacturing method can be heterogeneous multi-material injection molding. The two ends of the metal wire in the lens barrel of the camera module are connected to the photosensitive device and the circuit board of the camera module, and the electrical signal generated by the photosensitive device can be connected to the circuit board of the camera module.
[0095] In another implementation of the present application, the internal wiring is formed in the barrel wall via a heterogeneous multi-material injection molding process. Such a wiring method improves the reliability of the wiring.
[0096] Figure 5B The schematic diagram of the connection mode of the flexible circuit board of this example is shown. As shown in the figure, the camera module 410 includes a lens barrel, and the internal wiring 552 of the barrel wall of the lens barrel is electrically connected to the photosensitive device.

[0098] Display screen 620 , camera module 610 and photosensitive device 630 .
[0099] The camera module 610 includes a lens barrel, and a light inlet of the lens barrel is used to receive a first portion of light passing through a light-transmitting opening 621 of a display screen 620 .
[0100] The photosensitive device 630 is disposed on a side of the lens barrel facing the display screen 620 , and is used to sense the second portion of light passing through the light transmission opening 621 .
[0101] As shown in the figure, the display screen may be provided with a black glue layer 626. The black glue layer 626 has an opening 6261 forming a light-transmitting opening. Such a configuration effectively avoids the black glue layer from blocking external light.
[0102] In one example, the display screen 620 is provided with a light-emitting layer 624. The light-emitting layer 624 has an opening 6240 forming a light-transmitting opening. Such a configuration effectively avoids the light-emitting layer from blocking external light. It should be understood that the first opening and the second opening can both be adapted to the light-transmitting opening of the display screen. Preferably, the second opening is aligned with the first opening.
[0103] also, Figure 6B A side view schematic diagram of another example of an electronic device is shown. The light-emitting layer 624 includes a first light-emitting area 6241 and a second light-emitting area 6242. The light transmittance of the first light-emitting area 6241 is less than the light transmittance of the second light-emitting area 6242. The second light-emitting area 6242 is used to form a light-transmitting opening. It should be understood that the second light-emitting area 6242 can be processed to align with the opening 6261.
[0104] Since the light transmittance of the first light emitting area is less than that of the second light emitting area, the light emitting layer is effectively prevented from blocking external light. In addition, since the second light emitting area has a display function, this arrangement can improve the display effect of the display screen.
[0105] Specifically, in some electronic devices, the light-emitting layer of the display screen is not provided with an opening, but only an opening is provided in the black plastic layer, so that external light can enter the camera module through the second light-emitting layer. Due to this arrangement, the image can also be displayed in the area of the display screen corresponding to the area above the camera module.
[0106] It should be understood that the first light-emitting layer and the second light-emitting layer belong to the same light-emitting layer. The transmittance of the first light-emitting area is less than the transmittance of the second light-emitting area. For example, the density of the light-emitting point electronic components in the second light-emitting layer can be significantly lower than the density of the light-emitting electronic components in the first light-emitting layer. Since this arrangement can reduce the impact of the opening size of the display screen, the screen ratio of the display screen is further improved.
[0107] In addition, it should be understood that the present application is also applicable to electronic devices with cameras located at the back. When the camera module of the electronic device is equipped with a transparent cover plate or a transparent back plate, the present application can be applied to reduce the opening size and opening ratio of the panel or back plate.
[0108] also, Figure 6C A side view schematic diagram of another example of an electronic device is shown, as shown in the figure, a part of the photosensitive area senses the first part of the light through the second opening, and another part of the photosensitive area is blocked by the non-opening part of the black gel layer 626. This arrangement makes full use of the space corresponding to the light-transmitting area to increase the area of the photosensitive area.

In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, commodity or device including the element.
[0110] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
