Fig. 2 schematically shows a structural schematic diagram of an electronic device 200 according to an embodiment of the present disclosure.
As shown in fig. 2, the electronic device 200 may include an image capturing device 210, a display panel 220, a backlight module 230, a light emitting assembly 240, and a control assembly 250.
The display panel 220 is disposed at one side of the image capturing device 210, and the backlight module 230 is disposed between the image capturing device 210 and the display panel 220.
The backlight assembly 230 is configured to provide backlight to the display panel 220. The backlight module 230 includes a through hole disposed at a position opposite to the image capturing device 210.
The light emitting assembly 240 is fixed in the through hole, and the light emitting assembly is configured such that the light transmittance of the light emitting assembly is greater than a preset threshold value when the light emitting assembly 240 does not emit light. The control assembly 250 is used to control the light emitting assembly 240 to emit light or not to emit light.
According to the embodiment of the disclosure, the electronic device 200 is provided with the light emitting component 240 at the position where the backlight module 230 is opened, and the light emitting component provides brightness for the area corresponding to the position of the opening in the display panel 220, so that the display panel with the off-screen camera can normally display the picture.
According to an embodiment of the present disclosure, the image capture device 210 may be, for example, a camera. The camera may generally include a base, a lens, a chip, and the like. The lens may be mounted on the mount.
According to an embodiment of the present disclosure, the display panel 220 may be, for example, an LCD display screen. The display panel 220 may be disposed, for example, at a side close to the lens of the image pickup device 210.
According to an embodiment of the present disclosure, the backlight assembly 230 may include a through hole, the position of which corresponds to the position of the image capturing device.
According to the embodiment of the disclosure, the position of the display panel 220 covering the backlight module 230 corresponding to the through hole may not be provided with an opening, so that the display panel 220 can better display the picture. That is, the through hole formed in the backlight module 230 is a blind hole with respect to the whole electronic device (including the backlight module and the display panel). According to an embodiment of the present disclosure, the display panel 220 may include, for example, a polarizer or other components that make a picture on the display screen more visible to a user. Therefore, ensuring the integrity of the display panel 220 (i.e., not providing the opening on the display panel 220) can make the picture displayed by the electronic device clearer and better in quality.
According to an embodiment of the present disclosure, the light emitting assembly 240 is fixed in the through hole of the backlight assembly 230, for example, the light emitting assembly 240 may be connected to a sidewall of the through hole by an adhesive, thereby being fixed in the through hole. Alternatively, the light emitting assembly 240 is placed in the through hole while the bottom of the light emitting assembly 240 is supported by the image pickup device and the top of the light emitting assembly 240 is covered by the display panel, thereby fixing the light emitting assembly 240 in the through hole.
According to an embodiment of the present disclosure, the light transmittance of the light emitting assembly is greater than a preset threshold, which may be, for example, the light transmittance of the backlight module. The preset threshold value may also be, for example, 90%, 80%, etc. It can be understood by those skilled in the art that the preset threshold is not limited by the present disclosure, as long as the light transmittance of the light emitting assembly can satisfy the external light required by the image capturing device 210 to capture an image.
According to an embodiment of the present disclosure, the light emitting assembly may include an organic light emitting diode having a light transmittance greater than a preset threshold.
According to embodiments of the present disclosure, the light emitting assembly may be, for example, a transparent OLED.
According to embodiments of the present disclosure, the light emitting assembly may include a plurality of organic light emitting diodes controlled by the same control assembly.
For example, the light emitting assembly may comprise a plurality of transparent OLEDs, which may for example be connected together in series, to be controlled by one control assembly.
According to the embodiment of the disclosure, the plurality of transparent OLEDs are controlled by the same control assembly, so that a circuit formed by the light emitting assembly and the control assembly is simple, the wiring is less, the size of the light emitting assembly and the size of the through hole can be matched, and the plurality of transparent OLEDs are easy to control.
According to an embodiment of the present disclosure, the control assembly may include a power supply and a switching element. The power supply is used for supplying voltage to the light-emitting component, so that the light-emitting intensity of the light-emitting component corresponds to the voltage. The switching element is used for conducting or breaking the electrical connection between the power supply and the light emitting component.
Fig. 3A schematically illustrates a schematic diagram of a control assembly 250 according to an embodiment of the disclosure.
As shown in fig. 3A, the control assembly 250 may include a power source 251 and a switching element 252. The power source 251, the switching element 252, and the light emitting assembly 240 may be connected in series. The power source 251 is used to provide a voltage to the light emitting assembly 240, and the light emitting intensity of the light emitting assembly 240 is adapted to the voltage.
As shown in fig. 3A, when the switch element 252 is turned on, the power source 251 and the light emitting element 240 are turned on, and the power source 251 supplies a voltage to the light emitting element 240, so that a current flows through the light emitting element 240, and the light emitting element 240 emits light. When the switching element 252 is turned on, the power supply 251 and the light emitting element 240 are turned off, and the light emitting element 240 stops emitting light.
It is understood that in the circuit schematic shown in this embodiment, a plurality of light emitting components 240 may be included, i.e., the power source 251, the switching element 252 and the plurality of light emitting components 240 are connected in series.
Fig. 3B schematically illustrates a schematic diagram of a control assembly 250 according to another embodiment of the present disclosure.
In this embodiment, the light emitting assembly 240 may be, for example, a transparent OLED.
The control component 250 may be, for example, a driving circuit of the OLED, which may include a signal line 253 supplying a data signal Vdata corresponding to the voltage intensity of the power source; and a switching element 254. The switching element 254 may include, for example, a switching transistor M1. The voltage signal Vscan can be used to control the on and off of the switching transistor M1.
As shown in fig. 3B, the driving circuit may be a 2T1C driving circuit. The driving circuit may include a driving transistor DTFT, a switching transistor M1, and a storage capacitor C. In the example of fig. 3B, the driving transistor DTFT and the switching transistor M1 may be P-type thin film transistors. When the voltage signal Vscan is a low level signal, the switching transistor M1 is turned on, and the data signal Vdata is written into the storage capacitor C. When the voltage signal Vscan is converted to a high level signal, the switching transistor M1 is turned off, and the gate voltage stored in the storage capacitor C drives the transistor DTFT, so that the transistor DTFT generates a current corresponding to the value of Vdata to drive the OLED, thereby ensuring that the OLED continuously emits light within one frame of display.
According to the embodiment of the disclosure, the control component is further used for obtaining the current brightness level of the backlight module, and adjusting the voltage provided by the power supply to the light-emitting component according to the brightness level.
According to the embodiment of the disclosure, the electronic device can automatically adjust the luminance of the OLED, so that the luminance of the OLED is matched with the luminance of the backlight module, the luminance of the display panel 220 is uniform, and the viewing experience of a user is improved.
In this embodiment, the control component may, for example, receive information from a processing chip of the electronic device and have access to the memory unit. The processing chip is used for communicating with a driving chip of the backlight module to obtain the current light-emitting brightness of the backlight module and sending the current light-emitting brightness to the control component. The storage unit is used for storing a corresponding relation table of the light-emitting brightness grade and the voltage. The control component determines the voltage which the power supply should output in order to enable the OLED to reach the current brightness level of the emitted light by searching the corresponding relation table.
According to an embodiment of the present disclosure, the controlling component 250 for controlling the light emitting component 240 to emit light or not comprises: in the case of detecting that the electronic device is using the image capturing apparatus 210, the control component 250 controls the light emitting component 240 not to emit light; and the control component 250 controls the light-emitting component 240 to emit light in case that the electronic device is detected to be displaying through the display panel 220.
For example, when a camera of the electronic device is turned on, the control component 250 controls the light emitting component 240 not to emit light, so that sufficient external light enters the camera, thereby ensuring the quality of images collected by the camera.
For another example, in the scenario shown in fig. 1, the display area 110 of the display screen of the electronic device 100 is displaying a picture, and the control component 250 controls the light-emitting component 240 to emit light, so as to ensure that the display area 110 can normally display the picture.
For example, in the control module shown in fig. 3A, the switch element 252 may receive a control command sent by the processing chip, and may be turned on or off according to the control command. When the camera of the electronic device is turned on, the processing chip sends an off control instruction to the switching element 252 to control the switching element 252 to be turned off. When the camera of the electronic device is turned off, the processing chip sends a turn-on control command to the switching element 252 to control the switching element 252 to turn on.
For another example, in the control component shown in fig. 3B, the processing chip may send control instructions to control Vscan and M1. When the camera of the electronic device is turned on, the processing chip sends a low level to the switching element 254 to control M1 to be turned on. When the camera of the electronic device is turned off, the processing chip sends a high signal to the switching element 254 to control the M1 to turn off.
Another aspect of the present disclosure provides a control method, which may be applied to the electronic device described above.
Fig. 4 schematically illustrates a flow chart of a control method according to an embodiment of the present disclosure.
As shown in fig. 4, the method includes operations S410 to S420.
In operation S410, a control instruction is acquired.
In operation S420, the control assembly controls the light emitting assembly to emit light or not to emit light in response to the control command.
According to an embodiment of the present disclosure, an electronic device to which the control method may be applied may include an image capture device, a display panel, a backlight module, a light emitting assembly, and a control assembly. The display panel is arranged on one side of the image acquisition device, and the backlight module is arranged between the image acquisition device and the display panel. The backlight module comprises a through hole, and the through hole is arranged at a position opposite to the image acquisition device. The light-emitting component is fixed in the through hole and is configured to have light transmittance larger than a preset threshold value under the condition that the light-emitting component does not emit light. The control component is used for controlling the light-emitting component to emit light or not to emit light.
According to the embodiment of the present disclosure, controlling the control component to respond to the control instruction, so that the control component controls the light emitting component to emit light or not to emit light according to the control instruction comprises: if the control instruction indicates that the electronic equipment is using the image acquisition device, controlling to disconnect the electrical connection between the power supply and the light-emitting component; and if the control instruction instructs the electronic equipment to display through the display panel, controlling to conduct the electric connection between the power supply and the light-emitting component.
According to an embodiment of the present disclosure, the control instruction may be generated by the electronic device in response to detecting that the camera is switched from the on state to the off state, or may be generated by the electronic device in response to detecting that the camera is switched from the off state to the on state, for example.
According to the embodiment of the disclosure, the control component receives the control instruction, and controls the light-emitting component to emit light or not to emit light according to the control instruction.
Specifically, the control instruction may be, for example, a high-level signal or a low-level signal.

The control software executes the control instruction and sends a state instruction to the switch to control the switch to be switched on, and the power supply and the light-emitting component are switched on, so that the power supply supplies enough voltage to the light-emitting component.
For another example, in the scenario shown in fig. 3B, when the camera is switched from the on state to the off state, the voltage signal Vscan may be controlled to be changed to the high level signal, so that the switching transistor M1 is turned off, and the gate voltage stored in the storage capacitor C drives the transistor DTFT to generate a current to drive the OLED, thereby ensuring that the OLED continuously emits light in one frame of display. When the camera is switched from the off-on state to the on-state, the voltage signal Vscan can be controlled to be changed into a low level signal, and no current for driving the OLED is generated.
According to the embodiment of the disclosure, the method further comprises the steps of determining the current light-emitting brightness grade of the backlight module, and sending the current light-emitting brightness grade to the control component, so that the control component adjusts the voltage provided by the power supply to the light-emitting component according to the current light-emitting brightness grade.
