Referring to fig. 1 and fig. 2, an electronic device 1000 according to an embodiment of the present disclosure includes a display screen 10 and a time-of-flight component 20. The electronic device 1000 may further include a housing 30, where the housing 30 may be used to mount functional devices such as the display screen 10 and the time-of-flight assembly 20, and the functional devices may also be a main board, a dual camera module, a receiver, and the like. The specific form of the electronic device 1000 may be a mobile phone, a tablet computer, a smart watch, a head display device, etc., and the electronic device 1000 is used as a mobile phone for description in this application, it is understood that the specific form of the electronic device 1000 is not limited to a mobile phone, and is not limited herein.

The display screen 10 may be mounted on the housing 30, and specifically, the display screen 10 may be mounted on one surface of the housing 30 or both surfaces of the housing 30 opposite to each other. In the example shown in fig. 1, where the display screen 10 is mounted on the front face of the housing 30, the display screen 10 may cover 85% or more of the area of the front face, for example, up to 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 95% or even 100%. The display screen 10 may be used to display images, which may be text, images, video, icons, etc. information. Specific types of the display screen 10 may be a Liquid Crystal Display (LCD), an Organic Light-emitting diode (OLED) display screen, a Micro LED display screen, and the like.

The display screen 10 includes a display area 11, and the display area 11 can be used for displaying images. The shape of the display area 11 may be circular, elliptical, racetrack, rectangular with rounded corners, rectangular, etc. to adapt to different types of electronic devices 1000 and different user requirements.

Referring to fig. 3, the display area 11 is formed with a front surface 12 and a back surface 13 opposite to each other, the display area 11 can be used for displaying images, light emitted from the display screen 10 is emitted outward along a direction from the back surface 13 to the front surface 12, and the light is received by a user after passing through the front surface 12, that is, the user can view the images displayed on the display screen 10 from the front surface 12. Referring to fig. 1, it can be understood that the front surface 12 is a display surface, and the back surface 13 is a surface opposite to the display surface. The front surface 12 and the back surface 13 may be flat or curved.

In some examples, the display screen 10 may further include a non-display area, and the non-display area may be formed at a periphery of the display area 11. The non-display area may not be used for display, and the non-display area may be used for bonding with the housing 30 or for wiring, for example, the non-display area may be bonded with the housing 30 by an adhesive without affecting the display function of the display area 11. The display screen 10 may also be a touch display screen integrated with a touch function, and after obtaining image information displayed on the display screen 10, a user may perform touch on the display screen 10 to implement a predetermined interactive operation.

Referring to fig. 1 again, in some embodiments, the display region 11 includes a plurality of pixels, the plurality of pixels are arranged in a predetermined manner, and a micro gap exists between adjacent pixels. The display area 11 includes a first sub-display area 111 and a second sub-display area 112. The pixel density of the first sub-display region 111 is less than the pixel density of the second sub-display region 112.

The pixel density of the first sub-display region 111 is less than the pixel density of the second sub-display region 112, that is, the micro-gap of the first sub-display region 111 is greater than the micro-gap of the second sub-display region 112, the blocking effect of the first sub-display region 111 on light is small, and the transmittance of the light passing through the first sub-display region 111 is high.

In some embodiments, the pixel density of the first sub-display region 111 is greater than the pixel density of the second sub-display region 112, or the pixel density of the first sub-display region 111 is equal to the pixel density of the second sub-display region 112.

In some embodiments, the shapes of the first sub-display area 111 and the second sub-display area 112 may be set according to specific requirements, and are not limited herein, for example, the first sub-display area 111 may be set to be in a racetrack shape, a drop shape, etc., and the second sub-display area 112 and the first sub-display area 111 may be complementary and together form the display area 11 in a rectangular shape or a rounded rectangle shape, etc. The first sub display region 111 may be located near an edge of the display region 11, and the second sub display region 112 may be located at a middle position of the display region 11. The first sub-display area 111 may be used for displaying status icons of the electronic device 1000, for example, for displaying battery level, network connection status, system time, and the like of the electronic device 1000.

The time-of-flight component 20 may utilize the principles of time-of-flight ranging to obtain depth information of a target object for three-dimensional modeling, generating three-dimensional images, ranging, and the like. The time of flight module 20 may be mounted in the housing 30 of the electronic device 1000, and specifically, after being mounted on a rack, the rack and the time of flight module 20 may be mounted in the housing 30 together. Time of flight component 20 may include an optical transmitter 21 and an optical receiver 22.

Referring to fig. 1 to 3, the light emitter 21 is disposed on a side of the display screen 10 where the back surface 13 is located, or the light emitter 21 is disposed below the display area 11 (for example, may be disposed below the first sub-display area 111), and the laser pulses emitted by the light emitter 21 pass through the display area 11. Specifically, the light emitter 21 may include a light source and an optical element, and light (for example, infrared laser light) emitted from the light source passes through the optical element, is expanded, is emitted, and then passes through the display area 11 to be projected to the outside. In one example, the transmittance of the display area 11 may be 60% or more, so that the laser pulses emitted by the light emitter 21 are less lossy when passing through the display area 11.

The light receiver 22 may include an infrared sensor, the laser pulse is emitted to the target object, and after being reflected by the target object, the laser pulse can be obtained by the light receiver 22, and the light receiver 22 receives the laser pulse reflected by the target object, and the depth data of the target object can be obtained by combining the time when the light emitter 21 emits the laser pulse. The light receiver 22 may also be disposed on the side of the display screen 10 where the back surface 13 is located, i.e. below the display screen 10 (for example, may be disposed below the first sub-display area 111), and specifically may be disposed on the same bracket as the light emitter 21, or the light receiver 22 may be directly mounted on the housing 30. At this time, the light incident surface of the light receiver 22 may be aligned with the display region 11, and the laser pulse reflected by the target object passes through the display region 11 and is received by the light receiver 22.

In summary, since the light receiver 22 is disposed on the side of the display screen 10 where the back surface 13 is located, an opening aligned with the light receiver 22 does not need to be formed on the display screen 10, and the screen ratio of the electronic device 1000 is high. In addition, in the embodiment of the present application, the time-of-flight component 20 is disposed below the display screen 10, and compared with a structured light component that uses structured light to collect depth information, the display screen 10 has less influence on the collection depth of the time-of-flight component 20. Specifically, when the laser emitted by the structured light assembly passes through the display screen 10, the laser may be diffracted by the display screen 10, so that the laser pattern actually emitted into the environment is inconsistent with the laser pattern emitted by the structured light assembly, which may affect the accuracy of the depth information acquired subsequently according to the laser pattern reflected by the target object. Since the time-of-flight assembly 20 of the embodiment of the present application acquires the depth information of the target object according to the time-of-flight ranging principle, even if the laser pulse emitted by the light emitter 21 is diffracted by the display screen 10, the time difference between the emission and the reception of the laser is not affected, that is, the accuracy of the depth information acquired by the time-of-flight assembly 20 is high.

Referring to fig. 4, in some embodiments, the display screen 10 is formed with through slots 14, and the through slots 14 do not have a display function. The through-groove 14 penetrates the front surface 12 and the back surface 13. The light emitter 21 is arranged on the side of the rear surface 13 of the display screen 10, while the light emitter 21 is arranged to emit laser light pulses through the through slot 14. In one embodiment, the through groove 14 may be opened on the first sub-display region 111.

At this time, the light emitting surface of the light emitter 21 may be aligned with the through groove 14, and the laser pulse emitted by the light emitter 21 passes through the through groove 14 and enters the outside. In this embodiment, since the emitted laser pulse does not need to pass through the solid portion of the display area 11, the intensity of the laser pulse is not weakened or affected by refraction or the like of the solid portion of the display area 11, and the depth detection is more accurate.

Specifically, in the example shown in fig. 5, the through-groove 14 includes a notch 141 formed on an edge of the display screen 10, or the through-groove 14 intersects the edge of the display screen 10. The notch 141 may be formed on any one or more of the upper edge, the lower edge, the left edge, the right edge, and the like of the display screen 10. The shape of the notch 141 may be any shape such as triangle, semicircle, rectangle, racetrack, etc., and is not limited herein.

In the example shown in fig. 6, the through-groove 14 includes a through-hole 142 spaced from the edge of the display screen 10, or the through-groove 14 opens within the range enclosed by the edge of the display screen 10. The through holes 142 may be disposed near any one or more of the upper edge, the lower edge, the left edge, the right edge, and the like of the display screen 10. The shape of the through hole 142 may be any shape such as triangle, circle, rectangle, racetrack, etc., and is not limited herein.

In some examples, the through slot 14 may also include the notch 141 and the through hole 142. The number of the notches 141 and the through holes 142 may be equal or unequal.

Referring to fig. 3 and 4, in some embodiments, the electronic device 1000 further includes a cover 40, and the cover 40 is disposed on a side of the front surface 12 of the display screen 10. When the display screen 10 is provided with the through groove 14, the infrared transmitting layer 50 is disposed on the region of the cover plate 40 corresponding to the through groove 14.

The cover plate 40 may be made of a material having a good light transmission property, such as glass or sapphire. The infrared-transmitting layer 50 may be an infrared-transmitting ink or an infrared-transmitting film, and the infrared-transmitting layer 50 has a high transmittance, for example, a transmittance of 85% or more, to infrared light (for example, light having a wavelength of 940 nm), and has a low transmittance to light other than infrared light or is completely opaque to light other than infrared light. Therefore, it is difficult for a user to see the light emitter 21 aligned with the through-groove 14 through the cover plate 40, and the electronic device 1000 has a good appearance.

In some embodiments, the infrared transmission layer 50 is formed on a region of the cover plate 40 corresponding to the first sub-display region 111.

Referring to fig. 7, in some embodiments, the electronic device 1000 further includes a cover plate 40, the cover plate 40 is disposed on a side of the front surface 12 of the display screen 10, and an infrared antireflection film 60 is formed on a region of the cover plate 40 corresponding to the light emitter 21.

The infrared antireflection film 60 may increase the transmittance of infrared light, and when the light emitter 21 emits infrared laser light (i.e., infrared laser pulses), the infrared antireflection film 60 may increase the transmittance of the infrared laser light passing through the cover plate 40, so as to reduce the loss of the infrared laser light passing through the cover plate 40, thereby reducing the power consumption of the electronic device 1000. Specifically, the infrared reflection reducing coating 60 may be coated on the upper surface, the lower surface, or both the upper surface and the lower surface of the cover plate 40.

Of course, an infrared reflection reducing coating 60 may also be formed on the cover plate 40 in the region corresponding to the light receiver 22 to reduce the loss of the external infrared light passing through the cover plate 40 before reaching the light receiver 22. At this time, the visible light antireflection film 80 may be formed on the cover plate 40 in the region not corresponding to the light emitter 21 and the light receiver 22, so as to improve the transmittance of the visible light emitted from the display screen 10 when passing through the cover plate 40.

Referring to fig. 8, in some embodiments, an infrared antireflection film 60 is formed on a region of the display screen 10 corresponding to the light emitter 21.

The infrared antireflection film 60 may increase the transmittance of infrared light, and when the light emitter 21 emits infrared laser light, the infrared antireflection film 60 may increase the transmittance of the infrared laser light passing through the display screen 10, so as to reduce the loss of the infrared laser light passing through the display screen 10, thereby reducing the power consumption of the electronic device 1000. Specifically, infrared reflection reducing film 60 may be formed on front surface 12 or rear surface 13 of display region 11, or on both front surface 12 and rear surface 13 of display region 11. In one example, infrared antireflection film 60 may also be formed inside display screen 10, for example, when display screen 10 is an LCD display screen, infrared antireflection film 60 may be formed on a polarizer in display screen 10, or on an electrode plate of display screen 10, etc.

Of course, when the through groove 14 is not formed at the position of the display screen 10 corresponding to the light emitter 21, the infrared antireflection film 60 may also be formed in the area of the display screen 10 corresponding to the light emitter 21.

Referring to fig. 9, in some embodiments, an infrared-transmitting layer 50 is formed on a region of the display screen 10 corresponding to the light receiver 22. As described above, the infrared transmitting layer 50 has a high transmittance to infrared light, but has a low transmittance to light other than infrared light (e.g., visible light) or is completely opaque to light other than infrared light (e.g., visible light), and thus the user cannot see the light receiver 22.

Meanwhile, when the through groove 14 is not formed at the position of the display screen 10 corresponding to the light emitter 21, the infrared transmitting layer 50 may be formed in the area of the display screen 10 corresponding to the light emitter 21, so that the light emitter 21 is difficult to be seen by a user. In one embodiment, the infrared transmission layer 50 is formed on a region of the display screen 10 corresponding to the first sub-display region 111.

Referring to fig. 10, in some embodiments, the display screen 10 is formed with a through-slot 14 penetrating the front surface 12 and the back surface 13. The electronic device 1000 also includes a visible light camera 70, the visible light camera 70 being disposed in alignment with the through slots 14. The cover plate 40 has a visible light reflection reducing film 80 and/or an infrared cut-off film 90 formed in a region corresponding to the through groove 14.

The visible light camera 70 may be used to receive visible light through the cover plate 40 and the through slot 14 to capture images. Forming the visible light antireflection film 80 on the cover plate 40 in the region corresponding to the through groove 14 can increase the transmittance of visible light when the visible light passes through the cover plate 40, so as to improve the imaging quality of the visible light camera 70. Forming the infrared cut film 90 on the cover plate 40 in the region corresponding to the through-groove 14 can reduce the transmittance of infrared light when the infrared light passes through the cover plate 40, or completely prevent the infrared light from entering the visible light camera 70, to reduce the influence of the infrared light on imaging of the visible light camera 70.

Referring to fig. 11, an embodiment of the present application provides a control method, which can be used in the electronic device 1000 according to any of the above embodiments. The first sub-display area 111 and the second sub-display area 112 can be independently controlled, and the light receiver 22 corresponds to the first sub-display area 111, the control method includes:

01: determining whether the optical receiver 22 is on;

02: when the light receiver 22 is turned on, the first sub-display region 111 is controlled to display an image at a first display timing, and the light receiver 22 is controlled to perform exposure at an exposure timing, wherein an effective working state corresponding to the first display timing is staggered from an effective working state corresponding to the exposure timing.

Referring to fig. 12, the control method according to the embodiment of the present application can be implemented by the control device 400 according to the embodiment of the present application, and the control device 400 can be used in the electronic device 1000. The control device 400 includes a determination module 401 and a control module 402. Wherein, step 01 can be implemented by the determining module 401, and step 02 can be implemented by the controlling module 402. That is, the determining module 401 can be used to determine whether the optical receiver 22 is turned on. The control module 402 is configured to control the first sub-display region 111 to display an image at a first display timing and the optical receiver 22 to perform exposure at an exposure timing when the optical receiver 22 is turned on, wherein an effective working state corresponding to the first display timing is staggered from an effective working state corresponding to the exposure timing.

Referring to fig. 1, the control method of the present embodiment can be implemented by the electronic device 1000 of the present embodiment, that is, when the light receiver 22 is turned on, the first sub-display area 111 displays an image at a first display timing, the light receiver 22 performs exposure at an exposure timing, and an effective working state corresponding to the first display timing is staggered from an effective working state corresponding to the exposure timing. In some embodiments, the electronic device 1000 may further include a processor 200, wherein step 01 and step 02 may be implemented by the processor 200.

When the light receiver 22 is turned on, the light receiver 22 receives the laser pulses reflected by and passing through the first sub-display area 111, and at this time, the light used by the first sub-display area 111 to display images interferes with the light receiver 22, so that the laser pulses received by the light receiver 22 have a large error, and the depth information of the target object cannot be accurately obtained. Therefore, the effective working state corresponding to the exposure timing of the light receiver 22 and the effective working state corresponding to the first display timing of the first sub-display area 111 may be staggered, that is, the light receiver 22 is not exposed when the first sub-display area 111 displays an image, and the first sub-display area 111 does not display an image when the light receiver 22 is exposed, so that the interference caused to the light receiver 22 when the first sub-display area 111 displays an image can be reduced or avoided.

It will be appreciated that, in use, the light emitter 21 and the light receiver 22 may be turned on simultaneously, or the time interval between the turning on of the light emitter 21 and the turning on of the light receiver 22 is very small, so that the above-mentioned time when the light receiver 22 is turned on, i.e. the time when the light emitter 21 is turned on, can be considered.

Referring to fig. 1 again, in some embodiments, when the first sub-display section 111 displays an image, the electronic device 1000 generates a first interrupt signal to stop the exposure of the light receiver 22; and/or, the electronic device 1000 generates a second interrupt signal to stop the first sub-display section 111 from displaying the image when the optical receiver 22 is exposed.

Referring to fig. 13, in some embodiments, step 02 includes:

021: generating a first interrupt signal to stop the exposure of the light receiver 22 when the first sub-display section 111 displays an image; and/or

022: when the light receiver 22 is exposed, a second interrupt signal is generated to stop the display of the image in the first sub-display region 111.

Referring to fig. 12 again, in some embodiments, the steps 021 and 022 can be implemented by the control module 402, that is, the control module 402 can be configured to generate a first interrupt signal to stop the exposure of the light receiver 22 when the image is displayed in the first sub-display area 111; and/or, when the light receiver 22 is exposed, a second interrupt signal is generated to stop the display of the image in the first sub-display area 111. In addition, step 021 and step 022 can also be realized by the processor 200.

In some embodiments, a frame rate at which the first sub-display area 111 displays the image may be determined, for example, the first sub-display area 111 displays the image at a frame rate of 30 frames per second, 40 frames per second, or 60 frames per second, and the first display timing of the first sub-display area 111 may be determined according to the frame rate at which the first sub-display area 111 displays the image. When the first sub-display area 111 displays an image, the control signal corresponding to the first display timing may be at a high level, and at this time, the first interrupt signal may be generated to stop the exposure of the light receiver 22, and the control signal corresponding to the exposure timing of the light receiver 22 may be at a low level; when the first sub-display area 111 does not display an image, the control signal corresponding to the first display timing may be at a low level, the light receiver 22 may determine whether to perform exposure according to the frame rate of the acquired image, when the light receiver 22 performs exposure, the control signal corresponding to the exposure timing of the light receiver 22 may be at a high level, and when the light receiver 22 does not perform exposure, the control signal corresponding to the exposure timing of the light receiver 22 may be at a low level, so that the exposure timing of the light receiver 22 may be obtained, and the effective operating state corresponding to the first display timing (that is, the corresponding control signal is at a high level) and the effective operating state corresponding to the exposure timing (that is, the corresponding control signal is at a high level) may be staggered with each other. When the first sub-display area 111 displays the image, the light receiver 22 stops exposing, so that the interference of the light receiver 22 when the first sub-display area 111 displays the image can be reduced or avoided.

In some embodiments, the frame rate at which the image is acquired by the light receiver 22 may be determined, for example, the light receiver 22 is exposed at a frame rate of 30 frames per second, 40 frames per second, or 60 frames per second, etc., and the exposure timing of the light receiver 22 may be determined according to the frame rate at which the image is acquired by the light receiver 22. When the light receiver 22 performs exposure, the control signal corresponding to the exposure timing may be at a high level, and at this time, the second interrupt signal may be generated to stop displaying the image in the first sub-display region 111, and the control signal corresponding to the first display timing of the first sub-display region 111 may be at a low level; when the light receiver 22 does not perform exposure, the control signal corresponding to the exposure timing may be at a low level, the first sub-display area 111 may determine whether to display an image according to the frame rate of the displayed image, when the first sub-display area 111 displays an image, the control signal corresponding to the first display timing of the first sub-display area 111 may be at a high level, and when the first sub-display area 111 does not display an image, the control signal corresponding to the first display timing of the first sub-display area 111 may be at a low level, so that the first display timing of the first sub-display area 111 may be obtained and the effective operating state corresponding to the first display timing (i.e., the corresponding control signal is at a high level) and the effective operating state corresponding to the exposure timing (i.e., the corresponding control signal is at a high level) may be staggered with each other. When the light receiver 22 is exposed, the first sub-display area 111 stops displaying the image, so that the interference of the light receiver 22 when the first sub-display area 111 displays the image can be reduced or avoided.

Specifically, referring to fig. 14, in an example, the first sub-display area 111 and the second sub-display area 112 can be independently controlled, the display panel 10 is an independent panel structure, that is, the display panel 10 is an integral body, and each of the plurality of pixels of the display panel 10 can be independently controlled. The first sub-display area 111 includes a first set of pixels formed by a plurality of pixels, and the second sub-display area 112 includes a second set of pixels formed by a plurality of pixels. It is to be understood that the plurality of pixels within the first set of pixels and the plurality of pixels within the second set of pixels may each be independently controlled. At this time, the type of the display screen 10 may be a self-luminous display screen, such as an OLED display screen or a Micro LED display screen, each pixel of the self-luminous display screen may be independently controlled to emit light or not emit light or emit light with different light emission luminance, and the display timing of the first sub-display region 111 and/or the second sub-display region 112 may be controlled by controlling the light emission timing of the pixel. In addition, pixels of a self-emissive display screen may self-emit light to present a corresponding color.

Referring to fig. 15, in another example, the first sub-display area 111 and the second sub-display area 112 can be independently controlled, and the display screen 10 includes the first sub-screen 16 and the second sub-screen 17, that is, the display screen 10 may be composed of two independent sub-display screens (the first sub-screen 16 and the second sub-screen 17), and the first sub-screen 16 and the second sub-screen 17 can be independently controlled. The first sub screen 16 may form a first sub display region 111, and the second sub screen 17 may form a second sub display region 112. At this time, the types of the first sub-screen 16 and the second sub-screen 17 may be the same, for example, both are LCD display screens, both are OLED display screens, or both are Micro LED display screens; the types of the first sub-screen 16 and the second sub-screen 17 may also be different, for example, the first sub-screen 16 is a display screen (such as an LCD display screen) that emits light through a backlight, and the second sub-screen 17 is a display screen that emits light (such as an OLED display screen or a Micro LED display screen). For another example, the first sub-screen 16 is a self-luminous display screen (such as an OLED display screen or a Micro LED display screen), and the second sub-screen 17 is a display screen (such as an LCD display screen) which emits light through a backlight source. Of course, the first sub-screen 16 may be an OLED display screen, and the second sub-screen 17 may be a Micro LED display screen, and the specific selection manner is not limited to the above example. The display panel that emits light by the backlight may control the display timing of the first sub-display section 111 and/or the second sub-display section 112 by controlling the light emission timing of the backlight. Pixels of the display screen that emit light through the backlight may also exhibit corresponding colors under the influence of the backlight.

In some embodiments, when the first sub-screen 16 and the second sub-screen 17 are combined into the display screen 10, the human eye may not perceive the boundary line between the first sub-screen 16 and the second sub-screen 17, and when the first sub-screen 16 and the second sub-screen 17 display images, the human eye may not perceive the boundary line between the images displayed by the first sub-screen 16 and the second sub-screen 17 even though the first sub-screen 16 and the second sub-screen 17 display the same frame of image together.

The specific shapes of the first sub-screen 16 and the second sub-screen 17 can be set according to requirements, for example, the second sub-screen 17 is substantially rectangular, the first sub-screen 16 is also substantially rectangular, and the first sub-screen 16 and the second sub-screen 17 are connected to form the substantially rectangular display screen 10; for example, as shown in fig. 15, the second sub-screen 17 may be in the shape of a rounded rectangle with perforations 172, the first sub-screen 16 may be in the same shape as the perforations 172, the perforations 172 may be in the shape of racetrack, drop, etc., and the first sub-screen 16 and the second sub-screen 17 may be complementary in shape and may together form a display screen 10 in the shape of a rounded rectangle. Of course, the final shape of the display screen 10, the shape of the first sub-screen 16 or the second sub-screen 17 may also be circular, oval, racetrack, etc., without limitation. The first sub-screen 16 may be located at an edge position of the whole display screen 10, and the second sub-screen 17 may be located at a middle position of the whole display screen 10. The first sub-screen 16 may be used to display status icons of the electronic device 1000, such as battery level, network connection status, system time, etc. of the electronic device 1000.

Referring to fig. 16, in some embodiments, when the optical receiver 22 is turned on, the second sub-display area 112 displays images at a second display timing T1, and the period of the first display timing T2 is greater than the period of the second display timing T1.

Referring again to fig. 11, in some embodiments, the control method further includes:

03: when the light receiver 22 is turned on, the second sub-display area 112 is controlled to display the image at the second display timing T1, wherein the period of the first display timing T2 is greater than the period of the second display timing T1.

Referring to fig. 12 again, in some embodiments, the step 03 can be implemented by the control module 402, that is, the control module 402 can be configured to control the second sub-display area 112 to display the image at the second display timing T1 when the optical receiver 22 is turned on, wherein a period of the first display timing T2 is greater than a period of the second display timing T1. In addition, step 03 can also be implemented by processor 200.

In some embodiments, the second display timing T1 may be a relatively common display timing, the second display timing T1 corresponds to a frame rate of, for example, 60 frames per second, 72 frames per second, or 75 frames per second, and when the light receiver 22 is turned on, the images displayed in the second sub-display area 112 will not interfere with the light receiver 22, so that the second sub-display area 112 may display the images at the second display timing T1, and the second sub-display area 112 can clearly and stably display the images.

In some embodiments, the period of the first display timing T2 may be greater than the period of the second display timing T1, wherein the period may refer to the inverse of the frame rate, that is, when the light receiver 22 is turned on, the frame rate of the first sub-display area 111 displaying the image may be less than the frame rate of the second sub-display area 112 displaying the image. Specifically, for convenience of control, when the optical receiver 22 is turned on, the first display timing T2 and the exposure timing T3 may be interlaced with each other (please refer to fig. 16, when the control signal corresponding to the first display timing T2 is at a high level, the control signal corresponding to the exposure timing T3 is at a low level, when the control signal corresponding to the exposure timing T3 is at a high level, the control signal corresponding to the first display timing T2 is at a low level, and when the control signal corresponding to the first display timing T2 is at a low level, the control signal corresponding to the exposure timing T3 is at a high level), that is, the frame rate of the images displayed in the first sub-display area 111 is equal to the frame rate of the images acquired by the optical receiver 22, and the frame rate of the images acquired by the optical receiver 22 is usually less than the frame rate of the images displayed in the second sub-display area 112, so that the frame rate of the images displayed in the first sub-display area 111 is also less than the frame, that is, the period of the first display timing T2 is greater than the period of the second display timing T1. In addition, the period of the first display timing T2 is greater than the period of the second display timing T1, and power consumption of displaying images in the first sub-display area 111 can be reduced.

Of course, in other embodiments, the first display timing T2, the second display timing T1, and the exposure timing T3 may be set according to other requirements, for example, please refer to fig. 17, the period of the first display timing T2 may be smaller than the period of the second display timing T1; referring to fig. 18, the first display timing T2 is the same as the second display timing T1; referring to fig. 19, the period of the first display timing T2 may be shorter than the period of the exposure timing T3; the period of the first display timing T2 may be greater than the period of the exposure timing T3, so long as the effective operating state corresponding to the first display timing T2 is different from the effective operating state corresponding to the exposure timing T3, and the like, and the period is not particularly limited herein.

In some embodiments, when the light receiver 22 is turned off, the first sub-display section 111 and the second sub-display section 112 both display images at the second display timing.

04: when the light receiver 22 is turned off, the first sub-display area 111 and the second sub-display area 112 are controlled to display images at the second display timing.

Referring to fig. 12 again, in some embodiments, the step 04 may be implemented by the control module 402, that is, the control module 402 may be configured to control the first sub-display area 111 and the second sub-display area 112 to display the image at the second display timing when the optical receiver 22 is turned off. In addition, step 04 may also be implemented by the processor 200.

When the light receiver 22 is turned off, that is, the user does not need to use the light receiver 22 at this time, that is, the light receiver 22 does not need to receive the laser pulses reflected and passing through the first sub-display area 111 at this time, and there is no problem that the image displayed by the first sub-display area 111 interferes with the light receiver 22, so that the first sub-display area 111 and the second sub-display area 112 can be controlled to display the image at the second display timing, so that the whole display area 11 can clearly and stably display the image, and the user can feel when using the electronic device 1000.

In some embodiments, the electronic device 1000 includes a hardware clock, and the first display timing and the exposure timing are determined by the hardware clock. The first display time sequence and the exposure time sequence can be accurately determined through the same hardware clock, so that the first display time sequence and the exposure time sequence are on the same time line, the effective working state corresponding to the first display time sequence and the effective working state corresponding to the exposure time sequence are accurately staggered, and the interference to the light receiver 22 when the first sub-display area 111 displays images is reduced or avoided. The second display timing may also be determined by the hardware clock.

In some embodiments, the first display timing and the exposure timing may also be determined by using the same system clock, and the first display timing and the exposure timing are only required to be on the same time line so as to accurately stagger the effective operating state corresponding to the first display timing and the effective operating state corresponding to the exposure timing, which is not limited herein.

Please refer to fig. 14 and fig. 15, it can be understood that, in combination with the above description of the display panel 10, when the display panel 10 is an independent display panel 10, the control of the display timing of the first sub-display area 111 can be realized by controlling the light emitting timing of the first pixel set; controlling the display timing of the second sub-display section 112 can be achieved by controlling the light emission timing of the second set of pixels. When the display screen 10 includes the first sub-screen 16 and the second sub-screen 17, controlling the display timing of the first sub-display area 111 can be achieved by controlling the display timing of the first sub-screen 16; the control of the display timing of the second sub-display section 112 can be realized by controlling the display timing of the second sub-screen 17. For example, when the electronic device 1000 is playing a movie, the display area 11 displays one frame of movie, and the movie includes a tree, a man, and a woman, and then the man and the woman may be all located in the second sub-display area 112, most of the woman is located in the second sub-display area 112, and the arm is located in the first sub-display area 111. Or; the frame displayed in the first sub-display area 111 and the frame displayed in the second sub-display area 112 are two independent display frames, for example, when the electronic device 1000 is currently performing a task of playing a movie, the movie frame is displayed in the second sub-display area 112, and the first sub-display area 111 may synchronously display the battery power, the network connection status, the system time, and the like of the electronic device 1000, or synchronously display an instant messaging message or a message notification of each application program, and the like. Similarly, when the display screen 10 includes the first sub-screen 16 and the second sub-screen 17, the picture displayed by the first sub-screen 16 and the picture displayed by the second sub-screen 17 may also form a complete display picture together, or the picture displayed by the first sub-screen 16 and the picture displayed by the second sub-screen 17 are two independent display pictures.

In some embodiments, when the light receiver 22 is turned on, the first sub-display area 111 and the second sub-display area 112 may also be controlled to display in different display states. The different display states may be on or off, displayed with different brightness, and the like. The display states of the first sub-display area 111 and the second sub-display area 112 can be independently controlled, so that the user can control the second sub-display area 112 to normally display according to actual requirements, and the first sub-display area 111 is used in cooperation with the optical receiver 22. For example, when the light emitter 21 emits the laser pulse or the light receiver 22 receives the reflected laser pulse, the first sub-display area 111 may be turned off or the display brightness of the first sub-display area 111 may be adjusted down to reduce the influence of the light emitter 21 emitting the laser pulse to the scene or the influence of the light receiver 22 receiving the reflected laser pulse when the first sub-display area 111 displays.

Referring to fig. 20, another control method is provided in the present embodiment, in which the first sub-display area 111 and the second sub-display area 112 emit light together or can be controlled independently, and the light receiver 22 corresponds to the first sub-display area 111, and the control method includes:

05: determining whether the optical receiver 22 is on;

06: when the light receiver 22 is turned on, the display region 11 is controlled to display an image at a first display timing, and the light receiver 22 is controlled to perform exposure at an exposure timing, wherein an effective working state corresponding to the first display timing is staggered from an effective working state corresponding to the exposure timing.

Referring to fig. 12 again, the control method according to the embodiment of the present application can be implemented by the control device 400 according to the embodiment of the present application, and the control device 400 can be used in the electronic device 1000. The control device 400 includes a determination module 401 and a control module 402. Wherein, step 05 can be implemented by the determining module 401, and step 06 can be implemented by the controlling module 402. That is, the determining module 401 can be used to determine whether the optical receiver 22 is turned on. The control module 402 is configured to control the display area 11 to display an image at a first display timing and the light receiver 22 to perform exposure at an exposure timing when the light receiver 22 is turned on, and an effective working state corresponding to the first display timing is staggered from an effective working state corresponding to the exposure timing.

Referring to fig. 1 again, the control method of the present embodiment can be implemented by the electronic device 1000 of the present embodiment, that is, when the light receiver 22 is turned on, the display area 11 displays an image at a first display timing, the light receiver 22 performs exposure at an exposure timing, and an effective working state corresponding to the first display timing is staggered from an effective working state corresponding to the exposure timing. In some embodiments, the electronic device 1000 may further comprise a processor 200, wherein steps 05 and 06 may be implemented by the processor 200.

When the light receiver 22 is turned on, the light receiver 22 receives the laser pulses reflected and passing through the first sub-display area 111, and at this time, the light used by the first sub-display area 111 to display images interferes with the light receiver 22, so that a large error exists in the speckle image obtained by the light receiver 22, and the depth information of the target object cannot be accurately obtained. Therefore, the effective operating state corresponding to the exposure timing of the light receiver 22 and the effective operating state corresponding to the first display timing of the display area 11 may be staggered, that is, the light receiver 22 is not exposed when the display area 11 displays an image, and the display area 11 does not display an image when the light receiver 22 is exposed, so that the interference caused to the light receiver 22 when the first sub-display area 111 displays an image can be reduced or avoided.

Referring to fig. 1 again, in some embodiments, when the display area 11 displays an image, the electronic device 1000 generates a first interrupt signal to stop the exposure of the light receiver 22; and/or, the electronic device 1000 generates a second interrupt signal to stop the display area 11 from displaying the image when the light receiver 22 is exposed.

Referring to fig. 21, in some embodiments, step 06 includes:

061: generating a first interrupt signal to stop the exposure of the light receiver 22 when the display area 11 displays an image; and/or

062: when the light receiver 22 is exposed, a second interrupt signal is generated to stop the display of the image in the display region 11.

Referring to fig. 12 again, in some embodiments, step 061 and step 062 may be implemented by the control module 402, that is, the control module 402 may be configured to generate a first interrupt signal to stop the exposure of the light receiver 22 when the image is displayed on the display area 11; and/or, generating a second interrupt signal to stop the display of the image in the display area 11 when the light receiver 22 is exposed. In addition, step 061 and step 062 may also be implemented by the processor 200.

In some embodiments, the frame rate of the display area 11 displaying the image may be determined first, for example, the display area 11 displays the image at a frame rate of 30 frames per second, 40 frames per second, or 60 frames per second, etc., and the first display timing of the display area 11 may be determined according to the frame rate of the display area 11 displaying the image. When the display area 11 displays an image, the control signal corresponding to the first display timing may be at a high level, and at this time, the first interrupt signal may be generated to stop the exposure of the light receiver 22, and the control signal corresponding to the exposure timing of the light receiver 22 may be at a low level; when the display area 11 does not display an image, the control signal corresponding to the first display timing may be at a low level, the light receiver 22 may determine whether to perform exposure according to the frame rate of the acquired image, when the light receiver 22 performs exposure, the control signal corresponding to the exposure timing of the light receiver 22 may be at a high level, and when the light receiver 22 does not perform exposure, the control signal corresponding to the exposure timing of the light receiver 22 may be at a low level, so that the exposure timing of the light receiver 22 may be obtained, and the effective operating state corresponding to the first display timing (that is, the corresponding control signal is at a high level) and the effective operating state corresponding to the exposure timing (that is, the corresponding control signal is at a high level) may be staggered with each other. When the display area 11 displays an image, the light receiver 22 stops exposing, so that the interference of the light receiver 22 when the first sub-display area 111 displays an image can be reduced or avoided.

In some embodiments, the frame rate at which the image is acquired by the light receiver 22 may be determined, for example, the light receiver 22 is exposed at a frame rate of 30 frames per second, 40 frames per second, or 60 frames per second, etc., and the exposure timing of the light receiver 22 may be determined according to the frame rate at which the image is acquired by the light receiver 22. When the light receiver 22 performs exposure, the control signal corresponding to the exposure timing may be at a high level, at this time, the second interrupt signal may be generated to stop displaying the image in the display area 11, and the control signal corresponding to the first display timing of the display area 11 may be at a low level; when the light receiver 22 does not perform exposure, the control signal corresponding to the exposure timing sequence may be at a low level, the display area 11 may determine whether to display an image according to the frame rate of the displayed image, when the display area 11 displays an image, the control signal corresponding to the first display timing sequence of the display area 11 may be at a high level, and when the display area 11 does not display an image, the control signal corresponding to the first display timing sequence of the display area 11 may be at a low level, so that the first display timing sequence of the display area 11 may be obtained and the effective operating state corresponding to the first display timing sequence (i.e., the corresponding control signal is at a high level) and the effective operating state corresponding to the exposure timing sequence (i.e., the corresponding control signal is at a high level) may be staggered from each other. When the light receiver 22 is exposed, the display area 11 stops displaying the image, so that the interference of the light receiver 22 when the first sub-display area 111 displays the image can be reduced or avoided.

Specifically, referring to fig. 14, in an example, the first sub-display region 111 and the second sub-display region 112 emit light together, and the display panel 10 is an independent panel structure, that is, the display panel 10 is a whole. At this time, the type of the display screen 10 may be a display screen that emits light by a backlight, such as an LCD display screen or the like.

When the display panel 10 is an integral, independent panel structure, the control of the display area 11 can be facilitated, and the number of processes required for manufacturing the electronic device 1000 can be reduced, thereby reducing the cost of the electronic device 1000.

Referring to fig. 16, in some embodiments, when the light receiver 22 is turned off, the display area 11 displays an image at a second display timing T1.

Referring again to fig. 20, in some embodiments, the control method further includes:

07: when the light receiver 22 is turned off, the display area 11 is controlled to display the image at the second display timing T1.

Referring to fig. 12 again, in some embodiments, step 07 may be implemented by the control module 402, that is, the control module 402 may be configured to control the display area 11 to display the image at the second display timing T1 when the optical receiver 22 is turned off. Alternatively, step 07 may be implemented by processor 200.

When the light receiver 22 is turned off, that is, the user does not need to use the light receiver 22 at this time, that is, the light receiver 22 does not need to receive the laser pulses reflected and passing through the first sub-display area 111 at this time, and there is no problem that the image displayed by the first sub-display area 111 interferes with the light receiver 22, so that the display area 11 can be controlled to display the image at the second display timing T1, so that the image can be clearly and stably displayed in the whole display area 11, and the user can feel when using the electronic device 1000.

In some embodiments, the second display timing T1 may be a relatively common display timing, and the second display timing T1 may correspond to a frame rate of, for example, 60 frames per second, 72 frames per second, or 75 frames per second.

In some embodiments, the period of the first display timing T2 may be greater than the period of the second display timing T1, wherein the period may refer to the inverse of the frame rate, i.e., the frame rate of the display area 11 displaying the image when the light receiver 22 is turned on may be less than the frame rate of the display area 11 displaying the image when the light receiver 22 is turned off. Specifically, for convenience of control, when the light receiver 22 is turned on, the first display timing T2 and the exposure timing T3 may be interlaced with each other (please refer to fig. 16, when the control signal corresponding to the first display timing T2 is at a high level, the control signal corresponding to the exposure timing T3 is at a low level, and when the control signal corresponding to the first display timing T2 is at a low level, the control signal corresponding to the exposure timing T3 is at a high level), that is, the frame rate of the image displayed by the display area 11 when the light receiver 22 is turned on is equal to the frame rate of the image acquired by the light receiver 22, and the frame rate of the image acquired by the light receiver 22 is usually lower than the frame rate of the image displayed by the display area 11 when the light receiver 22 is turned off, so that the frame rate of the image displayed by the display area 11 when the light receiver 22 is turned on is lower than the frame rate of the image displayed by the display area 11 when the light receiver, that is, the period of the first display timing T2 is greater than the period of the second display timing T1. In addition, the period of the first display timing T2 is greater than the period of the second display timing T1, which can also reduce the power consumption of the display area 11 for displaying images when the light receiver 22 is turned on.

Referring to fig. 22, in some embodiments, when the display screen 10 is a single LCD display screen 93, or the first sub-screen 16 is the LCD display screen 93, or the second sub-screen 17 is the LCD display screen 93, or both the first sub-screen 16 and the second sub-screen 17 are the LCD display screen 93, the LCD display screen 93 may include a backlight module 931, a lower polarizer 932, a Thin-film transistor (TFT) substrate 933, a liquid crystal layer 934, a color filter 935, and an upper polarizer 936, which are sequentially disposed along a light emitting direction. The backlight module 931 may be regarded as a backlight source. The lower polarizer 932 and the upper polarizer 936 are used for controlling the passing or not of the light, and specifically, the upper polarizer 936 and the lower polarizer 932 form a barrier angle respectively, block the component perpendicular to the barrier in the light, and only allow the component parallel to the barrier to pass. TFT substrate 933 is used to provide a conductive path to generate a voltage. The color filter 935 is used to form a color image. The liquid crystal layer 934 includes liquid crystal molecules, and the electro-optic effect caused by the anisotropy of the liquid crystal molecule structure, that is, the anisotropy of the dielectric coefficient and the refractive index of the liquid crystal molecules, is different due to the different directions. The LCD panel 93 generates a voltage through the TFT substrate 933 according to the characteristics of the liquid crystal itself to form an electric field between the upper polarizer 936 and the lower polarizer 932, and controls the rotation of liquid crystal molecules by the electric field to change the traveling direction of light so that the light passes through or is blocked by the lower polarizer 932 and the upper polarizer 936, so that different gray-scale brightness can be formed by different electric fields.

Referring to fig. 23, in some embodiments, when the display panel 10 is a single OLED display panel 95, or the first sub-panel 16 is the OLED display panel 95, or the second sub-panel 17 is the OLED display panel 95, or both the first sub-panel 16 and the second sub-panel 17 are the OLED display panel 95, the OLED display panel 95 may include a substrate 951, an anode 952, a hole transport layer 953, a light emitting layer 954, an electron transport layer 955, and a cathode 956. Wherein the substrate 951 is used to support the entire OLED display 95. When a voltage is applied to the anode 952 and the cathode 956 of the OLED, electrons and holes are injected from the cathode 956 and the anode 952, respectively, into the organic functional layer sandwiched between the two electrodes. The injected electrons and holes migrate from the electron transport layer 955 and the hole transport layer 953, respectively, to the light emitting layer 954. After the electrons and holes are injected into the light-emitting layer 954, they are bound together by coulomb force to form hole pairs, i.e., excitons. The excitons migrate under the influence of the electric field, transferring energy to the dopant material in the light-emitting layer 954. Electrons in the dopant material of the light-emitting layer 954 absorb energy and then transition from a ground state to an excited state. Since the excited state is unstable, the electron transits from the excited state back to the ground state again, releasing energy in the form of a photon. Depending on the excited state energy level of the luminescent material, the electrons release photons of different energies during the transition back to the ground state, the energy determining the wavelength of the light, the different wavelengths meaning different colors of the light. Thus, the OLED display 95 can emit light of different colors in a self-luminous manner. The luminance or intensity of light emitted by the OLED display 95 depends on the properties of the light-emitting material and the amount of current applied. For the same OLED display screen 95, the greater the current, the higher the brightness of the light. Each pixel (composed of a plurality of sub-pixels that can self-emit light) in the OLED display screen 95 may be controlled to be on/off by an independent thin film transistor, so that each pixel may continuously and independently emit light.

Referring to fig. 24 and 25, in some embodiments, when the display screen 10 is a single Micro LED display screen 97, or the first sub-screen 16 is the Micro LED display screen 97, or the second sub-screen 17 is the Micro LED display screen 97, or both the first sub-screen 16 and the second sub-screen 17 are the Micro LED display screen 97, the Micro LED display screen 97 may include a driving substrate 971, a packaging substrate 972, a support 973, and a plurality of pixels 974. The driving substrate 971 and the package substrate 972 are disposed opposite to each other, and a plurality of pixels 974 are arranged between the driving substrate 971 and the package substrate 972. A visible light source 9741 is disposed in each pixel 974.

A display driving circuit (not shown) is disposed in the driving substrate 971, and the driving substrate 971 can control on/off and brightness of the light source in each pixel 974. The package substrate 972 is used for protecting the light source, and the material of the package substrate 972 may be plastic with certain hardness, such as polyethylene terephthalate (PET) or Polycarbonate (PC), or may be glass. The support 973 is used to keep a certain distance between the driving substrate 971 and the encapsulation substrate 972 and prevent excessive compression on the pixel 974.

Each pixel 974 further includes a lower pixel electrode 9742 and an upper pixel electrode 9743, the lower pixel electrode 9742 is disposed on the driving substrate 971, the upper pixel electrode 9743 is disposed under the encapsulation substrate 972, and the visible light source 9741 is sandwiched between the lower pixel electrode 9742 and the upper pixel electrode 9743. The material of the pixel electrode may be indium tin oxide or a conductive metal.

As shown in fig. 24, in one example, the plurality of visible light sources 9741 includes a red light source, a green light source, and a blue light source, and each visible light source 9741 and the corresponding pixel electrode form a pixel 974, so that the pixels 974 including different light sources emit light of different colors.

Referring to fig. 25, in another example, the structure of the pixel 974 may also include a visible light source 9741 and a color conversion layer 9744. For example, the plurality of visible light sources 9741 includes a red light source and a blue light source, and each of the visible light sources 9741 emits light of a corresponding color with the pixel 974 formed by the corresponding pixel electrode. The pixel 974 with the red light source emits red light, the pixel 974 with the blue light source emits blue light, and the pixel 974 with the blue light source and the color conversion layer 9744 emits green light. The pixels 974 also include a spacer layer 9745, the spacer layer 9745 facilitating height uniformity between the pixels 974.

To sum up, the LCD panel 93 can display images by controlling the backlight module 931 to emit light, wherein the backlight module 931 of the LCD panel 93 can only be controlled as a whole, i.e., the whole panel emits light or does not emit light; the OLED display 95 can display images by independently controlling the light emitting layers 954 of the pixels to emit light with different colors and brightnesses; the Micro LED display 97 can display images by independently controlling the visible light sources 9741 to emit light with different brightness and different colors.
