The control method of the electronic device 100 according to the embodiment of the present invention can be realized by the control device 20 according to the embodiment of the present invention. The control device 20 comprises an acquisition module 21, a judgment module 22, a first control module 23 and a second control module 24. Step 01 may be implemented by the obtaining module 21, step 02 may be implemented by the determining module 22, step 03 may be implemented by the first control module 23, and step 04 may be implemented by the second control module 24. That is, the acquiring module 21 is used for acquiring a current image on the side opposite to the transparent display 13 when an incoming call comes in. The judging module 22 is used for judging whether the incoming call is answered according to the current image. The first control module 23 is used to turn off the light-transmissive display 13 and turn on the proximity sensor 16 when an incoming call is answered. The second control module 24 is used for controlling the light-transmitting display 13 to be turned off or turned on according to the detection data of the proximity sensor 16.
Referring to fig. 3 and fig. 4, an electronic device 100 is further provided according to an embodiment of the invention. The electronic device 100 includes a light transmissive display 13, a proximity sensor 16, a processor 17, and an image capture device 30. The light-transmitting display 13 includes an upper surface 131 and a lower surface 132, the lower surface 132 is opposite to the upper surface 131, and the light-transmitting display 13 emits light through the upper surface 131 for displaying. A proximity sensor 16 is disposed below the light-transmissive display 13, and the proximity sensor 16 is used to emit infrared light and receive infrared light emitted by an object to detect a distance from the object to the electronic device 100. Steps 01 to 04 are implemented by the processor 17. That is, the processor 17 is configured to: first, when an incoming call enters, the image capturing device 30 captures a current image of a side opposite to the transparent display 13, and the processor 17 obtains the current image. Then, whether the incoming call is answered is judged according to the current image. Subsequently, when the incoming call is answered, the light-transmitting display 13 is turned off and the proximity sensor 16 is turned on. Finally, the light-transmitting display 13 is controlled to remain off or on according to the detection data of the proximity sensor 16.
Specifically, in the embodiment of the present invention, the control device 20 may be applied to a computer device, where the computer device may be a mobile phone, a tablet computer, a notebook computer, or the like, and the electronic device 100 according to the embodiment of the present invention may also be one of the computer devices.
The embodiment of the present invention is described by taking the electronic device 100 as a mobile phone as an example. The top position of the mobile phone screen is generally provided with a proximity sensor to determine the distance between the mobile phone and the obstacle and make corresponding adjustment, so that misoperation of a user can be prevented, and the power of the mobile phone can be saved. When a user answers or calls a call and brings the mobile phone close to the head, the proximity sensor generates detection information by calculating the time for the emitter to emit infrared light and the receiver to receive reflected infrared light, and the processor sends a corresponding instruction to control the transparent display screen to be closed according to the detection information. When the mobile phone is far away from the head, the processor calculates and sends an instruction to control the light-transmitting display screen to be opened again according to the detection information fed back by the infrared sensor.
With the development of mobile terminals, a full screen is a new development trend, generally, the proximity sensor 16 is disposed at the top of a screen display area, and in order to increase the screen occupation ratio of a mobile phone, the proximity sensor 16 needs to be disposed below the display area of the display screen. However, infrared light emitted from the proximity sensor 16 may be irradiated on the TFT of the display panel, and under the irradiation of the infrared light, electrons of some substances inside the TFT may be excited by photons to form a current. The proximity sensor 16 emits infrared light pulses which cause the display to blink.
Referring to fig. 5, 6 and 11, in the control method according to the embodiment of the invention, when an incoming call enters, the image capturing device 30 captures a current image. At this time, the incoming call is not answered yet, and the proximity sensor 16 is in the off state, so that the display of the light-transmitting display screen 13 is not influenced. Then, the processor 17 determines whether the incoming call is answered according to the current image. Specifically, the processor 17 may determine whether the incoming call is answered according to the size of the proportion of the face region in the current image or whether the face region in the current image includes the human ear region. For example, referring to fig. 5, when it is detected that the proportion of the face area in the current image is greater than the predetermined proportion, it is determined that the call is answered. In addition, referring to fig. 11, in some examples, whether the phone call is answered may also be determined by detecting whether the face region includes an ear region. When the incoming call is detected to be answered by the user, the transparent display screen 13 is turned off, and the proximity sensor 16 works normally. During the process of answering the call, the light-transmitting display screen is controlled to be kept off or lighted according to the detection data of the proximity sensor 16. Specifically, when the user approaches the electronic device 100 to the head while receiving the incoming call, the proximity sensor 16 calculates the distance between the electronic device 100 and the head according to the transmitted and received infrared light, and keeps the light-transmitting display 13 off while approaching the head. When the incoming call is hung up, the proximity sensor 16 is turned off, and the light-transmitting display 13 is lighted. This can avoid causing the translucent display 13 to flicker.
In the embodiment of the present invention, the current image is an image captured by the image capturing device 30 when an incoming call arrives. In addition, the face region in the acquired current image includes a side face region. Meanwhile, it is understood that, in the embodiment of the present invention, the incoming call includes an incoming call in a voice call type application.
Referring to fig. 7, in some embodiments, step 02 includes the steps of:
021: identifying a face region in a current image;
022: calculating the proportion of the face area to the current image; and
023: and determining that the incoming call is answered when the proportion is larger than the preset proportion.
Referring to fig. 8, in some embodiments, the determining module 22 includes an identifying unit 221, a calculating unit 222, and a determining unit 223. The identifying unit 221 is configured to implement step 021. The calculation unit 222 is used to implement step 022. The determination unit 223 is used to implement step 023. That is, the recognition unit 221 is configured to recognize a face region in the current image captured by the image capture device 30. The calculation unit 222 is used for calculating the ratio of the face region to the current image. The determination unit 223 is used to determine that the incoming call is answered when the ratio is greater than a predetermined ratio.
Referring to fig. 4, the processor 17 of the electronic device 100 is configured to implement step 021, step 022 and step 023. That is, the processor 17 is configured to identify a face region in the current image captured by the image capturing device 30 and calculate a ratio between the face region and the current image. The processor 17 is also configured to determine that the incoming call is answered when the ratio is greater than a predetermined ratio.
Specifically, referring to fig. 5 and 6, when a call comes, the image capturing device 30 is turned on to capture an image of the user. And then identifying a face region in the acquired image, wherein the face region in the image comprises a side face region. The processor 17 then calculates the proportion of the face region to the current image. During the process of receiving the incoming call, the user will bring the electronic device 100 close to the side face and the head. In this process, the proportion of the face area in the current image will become larger. In fig. 5, the ratio of the face area is greater than the preset ratio, and it can be determined that the user has answered the incoming call. At this time, the light-transmitting display 13 is turned off and the proximity sensor 16 is turned on. In fig. 6, the proportion of the face area is smaller than the predetermined proportion, and it can be determined that the user does not answer the call. At this time, the proximity sensor 16 remains off.
It should be noted that the predetermined ratio may be a preset value after the electronic device 100 is tested before being shipped from a factory. And when the ratio of the face area to the current image is larger than the preset ratio, the incoming call is received by the user. When the ratio of the face area to the current image is smaller than the predetermined ratio, it indicates that the user does not intend to answer the incoming call or the electronic device 100 is in a mute state, and the user does not know whether the incoming call is made. Of course, it is also possible that the user answers the call in other ways, e.g. with a headset, with a speaker switched on during answering, etc.
Referring to fig. 9, in some embodiments, step 02 includes the steps of:
024: identifying a face region in a current image;
025: judging whether the human face area comprises a human ear area or not; and
026: and determining that the incoming call is answered when the face area comprises the ear area.
Referring to fig. 10, in some embodiments, the determining module 21 includes a recognizing unit 221, a determining unit 223, and a determining unit 224. Recognition unit 221 is configured to implement step 024, determination unit 224 is configured to implement step 025, and determination unit 223 is configured to implement step 026. That is, the recognition unit 221 is configured to recognize a face region in the current image, and the determination unit 224 is configured to determine whether the face region includes an ear region. The determination unit 223 is configured to determine that the incoming call is answered when the face region includes a human ear region.
Referring to fig. 4, the processor 17 of the electronic device 100 is configured to implement step 024, step 025, and step 026. That is, the processor 17 is configured to recognize a face region in the current image, determine whether the face region includes an ear region, and determine that the incoming call is answered when the face region includes the ear region.
Specifically, during an incoming call, the image capture device 30 is turned on. When the user answers the incoming call, the electronic device 100 is brought close to the side face and the ear area. In this process, the image pickup device 30 picks up an image of the user. Referring to fig. 11, when it is recognized that a side face region exists in the current image and an ear region exists in the side face region, it may be determined that the incoming call has been answered by the user. At this time, the light-transmitting display 13 is turned off and the proximity sensor 16 is turned on. In this way, the proximity sensor 16 is prevented from affecting the translucent display 13 during operation. It will be understood that detecting that the face area does not include the ear area indicates that the user is not answering the call or answering in other ways, such as answering with a headset, turning on a speaker during answering, etc.
The detection of the face may be performed based on a preset face template, color, and the like, if the face exists in the recognition scene, the part connected with the face may be determined to be a portrait area, and the specific implementation manner is not limited herein. The determination of the portrait may also be performed, for example, by matching with a portrait template. It will be appreciated that the identification of the face region may also be to identify whether there are consecutive patches and then identify the contour to determine the face and ear regions.
The image capture device 30 may be a photo-active camera, such as a front camera of the electronic device 100. It is understood that the image capture device 30 is disposed in front of the electronic device 100 and faces the user. The image capture device 30 may capture an RGB image of the current image at which the user is located. The image capturing device 30 may also be a depth camera, and in the depth image, the depth data corresponding to the features of the nose, the eyes, the ears, and the like in the face region are different, for example, when the electronic device 100 is faced to the face side, the depth data corresponding to the nose may be larger, and the depth data corresponding to the ears may be smaller in the captured depth image. The number of the image capturing devices 30 may be plural, for example, two visible light cameras.
Referring to fig. 12, in some embodiments, the step 04 further includes the steps of:
041: and when the distance is greater than the distance threshold value, detecting whether the incoming call is kept answering, and if so, controlling the light-transmitting display screen to be lightened and keeping the proximity sensor to be started.
Referring to fig. 13, in some embodiments, the second control module 24 includes a first control unit 241. The first control unit 241 is configured to implement step 041. That is, the first control unit 241 is configured to detect whether the incoming call remains answered when the distance is greater than the distance threshold, and if so, control the transparent display 13 to illuminate and keep the proximity sensor 16 turned on.
Referring to FIG. 4, the processor 17 of the electronic device 100 is configured to implement step 041. That is, the processor 17 is configured to detect whether the incoming call remains answered when the distance is greater than the distance threshold, and if so, control the transparent display 13 to illuminate and keep the proximity sensor 16 turned on.
Specifically, in a situation where the user keeps answering the incoming call, the user may cause the electronic device 100 to be away from the head due to some operation. That is, the distance between the electronic device 100 and the head is greater than the distance threshold. At this time, the translucent display 13 is controlled to light up and keep the proximity sensor 16 on. In this case, the user generally does not need to view the contents of the light-transmissive display 13, and the effect of flicker on the user experience can be ignored.
The distance threshold is a value preset before the electronic device 100 is shipped. The distance threshold is a fixed value that has been set at initialization. In general, the distance threshold may be set empirically at the time of factory shipment, or may be determined according to the emission power of the infrared light, for example, the distance threshold is smaller when the emission power of the infrared light is smaller, and the distance threshold is larger when the emission power of the infrared light is larger.
Referring to fig. 14, in some embodiments, the control method further includes the steps of:
05: and if the incoming call is hung up, controlling the proximity sensor to close and lightening the light-transmitting display screen.
Referring to fig. 15, in some embodiments, the control device 20 further includes a third control module 25. The third control module 25 is configured to implement step 05. That is, the third control module 25 is configured to control the proximity sensor 16 to turn off and light the transparent display 13 when the incoming call is suspended.
Referring to fig. 4, the processor 17 of the electronic device 100 is configured to implement step 05. That is, the processor 17 is configured to control the proximity sensor 16 to turn off and illuminate the light-transmissive display 13 when the incoming call is suspended.
Specifically, when it is detected that the incoming call is hung up, the proximity sensor 16 is turned off, and the translucent display 13 is lit. In this way, the proximity sensor 16 does not operate, and does not cause the translucent display 13 to flicker. It can be understood that the incoming call is hung up in two cases, one is that the incoming call is directly hung up, that is, the incoming call is directly hung up for some reason when the user call is not finished yet. For example, the electronic device 100 hangs up directly due to poor call signal. Another is to hang up after the user completes answering. After the call is disconnected, the proximity sensor 16 is turned off, and the transparent display 13 is turned on, so that the user can perform the next operation on the electronic device 100.
Referring to fig. 16, in some embodiments, the electronic device 100 further includes a first coating layer 14. The first coating layer 14 is applied to the lower surface 132 and covers the proximity sensor 16. The first coating layer 14 is for transmitting infrared light and intercepting visible light, and the proximity sensor 16 is for emitting and/or receiving infrared light through the first coating layer 14 and the light transmissive display 13. The proximity sensor 16 may be disposed anywhere below the lower surface 132. The first coating layer 14 may be an IR ink, and since the IR ink has a characteristic of low transmittance to visible light, the proximity sensor 16 disposed under the first coating layer 14 may not be perceived based on the vision of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR ink has a characteristic of high transmittance to infrared light, so that the proximity sensor 16 can stably emit and receive infrared light, thereby ensuring normal operation of the proximity sensor 16.
In some embodiments, the proximity sensor 16 includes an emitter 161 and a receiver 162, the emitter 161 for emitting infrared light through the first coating layer 14 and the light transmissive display 13, the receiver 162 for receiving the infrared light emitted through the object to detect the distance of the object from the electronic device 100.
Specifically, when the user is answering or making a call, the electronic device 100 is close to the head, the emitter 161 emits infrared light, the receiver 162 receives reflected infrared light, the processor calculates the time from emission to reflection of infrared light, and then sends a corresponding instruction to control the screen to be off, and when the electronic device 100 is far away from the head, the processor calculates according to the data fed back again and sends the instruction to control the screen to be on again. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.
In the above embodiment, the orthographic projection of the proximity sensor 16 on the lower surface 132 is located within the orthographic projection of the first coating layer 14 on the lower surface 132.
Specifically, in the process of process assembly, an assembly gap is usually required to be reserved for the installation of the proximity sensor 16, so that a gap occurs between the proximity sensor 16 and other elements, visible light enters from the gap, and a light leakage phenomenon occurs. Therefore, in the direction in which the proximity sensor 16 and the light-transmitting display 13 are stacked, the area of the orthographic projection of the first coating layer 14 on the lower surface 132 is larger than the area of the orthographic projection of the proximity sensor 16 on the lower surface 132, so that the proximity sensor 16 can be sufficiently shielded by the first coating layer 14 without affecting the normal operation of the proximity sensor 16, and the effect that the proximity sensor 16 is invisible when the electronic device 100 is viewed from the outside can be achieved.
In the above embodiment, the first coating layer 14 includes an IR ink having a transmittance of greater than 85% for infrared light and a transmittance of less than 6% for visible light, and the IR ink transmits infrared light having a wavelength of 850nm to 940 nm.
Specifically, since the IR ink has a characteristic of low transmittance to visible light, the proximity sensor 16 disposed under the first coating layer 14 is not observed based on the visual sense of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR ink has a characteristic of high transmittance to infrared light, so that the proximity sensor 16 can stably emit and receive infrared light, thereby ensuring normal operation of the proximity sensor 16.
Referring to fig. 17, in the above embodiment, the electronic device 100 further includes a second coating layer 15 coated on the lower surface 132 and connected to the first coating layer 14.
Specifically, the first coating layer 14 is mainly used for transmitting infrared light and blocking the proximity sensor 16, but since the cost of the IR ink used for the first coating layer 14 is higher than that of the ordinary black ink, it is not favorable to reduce the production cost if the lower surface 132 is entirely coated with the IR ink, and the ordinary black ink can achieve lower transmittance of visible light than the IR ink and more excellent blocking effect. Therefore, the second coating layer 15 is arranged, so that the production cost is reduced, and the shielding effect meets the process requirement.
In certain embodiments, the second coating layer 15 includes a black ink having a transmittance to visible light and a transmittance to infrared light of less than 3%.
Specifically, on one hand, the black ink has lower light transmittance to visible light and more obvious shielding effect compared with the IR ink, and meets the process requirements better. On the other hand, the black ink has lower cost than the IR ink, which is beneficial to reducing the production cost.
In some embodiments, the light transmissive display 13 comprises an OLED display.
In particular, an Organic Light-Emitting Diode (OLED) display screen has good Light transmittance and can pass visible Light and infrared Light. Therefore, the OLED display screen does not affect the emission and reception of infrared light by the proximity sensor 16 in the case of exhibiting the content effect. The light-transmitting display screen 13 may also be a Micro LED display screen, and the Micro LED display screen also has good light transmittance for visible light and infrared light. Of course, these display screens are merely exemplary and embodiments of the present invention are not limited in this respect.
Referring to fig. 17, in some embodiments, the electronic device 100 further includes a light-transmissive cover 11 and a light-transmissive touch panel 12. The light-transmitting cover plate 11 is formed on the light-transmitting touch panel 12, the light-transmitting touch panel 12 is disposed on the light-transmitting display screen 13, the upper surface 131 of the light-transmitting display screen 13 faces the light-transmitting touch panel 12, and the light-transmitting cover plate 11 and the light-transmitting touch panel 12 have a visible light transmittance and an infrared light transmittance greater than 90%.
Specifically, the light-transmitting touch panel 12 is mainly used for receiving an input signal generated when a user touches the light-transmitting touch panel 12 and transmitting the input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the light-transmitting touch panel 12. The light-transmitting touch panel 12 and the light-transmitting display screen 13 can be attached by adopting an In-Cell or On-Cell attaching technology, so that the weight of the display screen can be effectively reduced, and the overall thickness of the display screen can be reduced. In addition, the transparent cover 11 is disposed on the transparent touch panel 12, so as to effectively protect the transparent touch panel 12 and the internal structure thereof, and prevent the transparent touch panel 12 and the transparent display 13 from being damaged by external force. The light transmittance of the light-transmitting cover plate 11 and the light-transmitting touch panel 12 to visible light and infrared light is greater than 90%, which is not only beneficial to the light-transmitting display screen 13 to better display the content effect, but also beneficial to the proximity sensor 16 arranged below the light-transmitting display screen 13 to stably emit and receive infrared light, and ensures the normal work of the proximity sensor 16
Referring to FIG. 17, in some embodiments, electronic device 100 further includes a buffer layer 18 covering lower surface 132 and avoiding proximity sensor 16.
Specifically, the buffer layer 18 is used to buffer impact and prevent shock so as to protect the light-transmitting touch panel 12, the light-transmitting display screen 13 and the internal structure thereof, and prevent the display screen from being damaged due to external impact. Cushioning layer 18 may be made of foam or rubber or other soft material. Of course, these cushioning materials are merely exemplary and embodiments of the present invention are not limited in this respect. Furthermore, avoiding the proximity sensor 16 during the placement of the buffer layer 18 may prevent the buffer layer 18 from obscuring the proximity sensor 16, thereby preventing the proximity sensor 16 from being affected during the emission and reception of infrared light.
Referring to FIG. 18, in such an embodiment, electronic device 100 further includes a metal sheet 19 overlying buffer layer 18 and avoiding proximity sensor 16.
Specifically, the metal sheet 19 is used for shielding electromagnetic interference and grounding, and has a function of diffusing temperature rise. The metal sheet 19 may be cut out of a metal material such as copper foil or aluminum foil. Of course, these metal materials are merely exemplary and embodiments of the present invention are not limited thereto. Furthermore, avoiding the proximity sensor 16 during the process of disposing the metal sheet 19 can prevent the metal sheet 19 from shielding the proximity sensor 16, thereby avoiding the proximity sensor 16 from being affected during the process of emitting and receiving infrared light.
In the above embodiment, the electronic device 100 further includes a housing. The shell is used for receiving the elements for protection.
