Description
Technical Field

At present, part of smartphones are provided with an under-screen fingerprint unlocking function. When the fingerprint unlocking function is started, a highlight area is formed in the finger pressing area on the display screen of the smart phone, and the display screen works in FOD (fingerprint on display) mode. Then, detecting the highlighted area may obtain a fingerprint of the finger and unlock the display.
Referring to fig. 1, a smart phone in the related art adopts the following power supply scheme:
when switching from the normal display mode (AOD, always on display) to the FOD mode, the processor AP issues a mode switching instruction to the driving chip DDIC, which issues a wire control signal to the power management chip PMIC, to control the voltage of the light emitting diode.
However, the inventors found that: referring to fig. 2, the processor AP issues a mode switching instruction to the driving chip DDIC, and at least needs to wait for one frame, i.e. there is a time delay t3; the driving chip DDIC sends a switch control signal to the completion of the voltage switching, at least needing to wait for the time of another frame, namely, having a time delay t4; the driving chip DDIC sends a wire control signal to the power management chip PMIC to control the voltage switching.

Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described by way of example below are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus consistent with some aspects of the disclosure as detailed in the accompanying claims.
In the related art, there is a delay between the processor in the electronic device issuing the mode switching command and the power management chip completing the switching of the voltage. For example, when a switching instruction occurs in a delayed period of time, an untimely switching voltage of the power management chip PMIC may cause an error to occur in which the AOD mode is high or the FOD mode is low.
To solve the above technical problems, the embodiments of the present disclosure provide a method and apparatus for controlling display mode switching, an electronic device, and a storage medium, fig. 3 is a block diagram of an electronic device according to an exemplary embodiment, and referring to fig. 3, an electronic device is disclosed, which includes a processor 10 and a display screen 20. The processor 10 includes a preset first voltage pin P1 and a preset second voltage pin P2, and the first voltage pin P1 of the processor 10 is connected to the display screen 20 through a first power line (e.g., ELVDD may be used); the second voltage pin P2 of the processor 10 is connected to the display 20 via a second power line (e.g., ELVSS may be used).
The processor 10 is configured to adjust the electric potentials of the first voltage pin P1 and the second voltage pin P2, so that the display screen 20 switches from the current display mode to the target display mode according to the electric potentials on the first power line and the second power line.
In an example, the current display mode and the target display mode may be any two different display modes of the electronic device, and the two display modes support unidirectional switching or bidirectional switching. For example, the switching of the current display mode to the target display mode may be one and the other of the AOD mode and the FOD mode.
In an example, the processor 10 includes a controller 11 and a power management unit 12. The controller 11 may be implemented by a chip or a circuit having a processing function, such as a microprocessor, a digital processing chip, or a single chip microcomputer, and is configured to send a mode switching instruction to the power management unit 12 when a trigger condition is satisfied. The power management unit 12 may be implemented using a power management chip or a power management circuit. The power management unit 12 is connected to the controller 11, and is configured to calculate a voltage required for a target display mode according to a mode switching command, and adjust potentials of the first voltage pin P1 and the second voltage pin P2 according to the required voltage. In particular, the power management unit may further preset a required potential in the target display mode, and when a mode switching instruction is received, the required potential may be obtained by directly looking up a table. In addition, the power management unit 12 supplies power to the controller 11 in addition to the display 20.
In one embodiment, the controller 11 and the power management unit 12 may be integrated together, and the first voltage pin P1, the second voltage pin P2, and the third voltage pin P3 are reserved during packaging, so as to facilitate subsequent electrical connection.
In an example, the processor 10 may also obtain detection data before determining to adjust the potentials of the first voltage pin P1 and the second voltage pin P2, and determine whether to adjust the potentials of the first voltage pin P1 and the second voltage pin P2 based on whether the detection data satisfies the trigger condition. Wherein the detection data satisfying the trigger condition may include any one of the following: a first trigger operation for instructing to switch to the target display mode is detected, and a second trigger operation for instructing to exit the current display mode is detected.
In one example, the current display mode of the display screen 20 includes one of an AOD mode and a FOD mode, and the target display mode includes the other of the AOD mode and the FOD mode; i.e. switching from the current display mode to the target mode comprises: switching from the AOD mode to the FOD mode or from the FOD mode to the AOD mode. In this example, the first triggering operation may include one of an operation of touching the screen with a finger and an operation of leaving the screen with a finger, and the second triggering operation includes the other of the operation of touching the screen with a finger and the operation of leaving the screen with a finger.
In an example, the electronic device may further be provided with a component for acquiring detection data, such as an optical sensor, a pressure sensor, or an operation key, and the technician may set according to a specific scenario, which is not limited herein.
Taking the detection data as light sensation data obtained by the optical sensor as an example, the electronic device may further include an optical sensor (not shown in the figure) disposed below the display screen 20. The optical sensor may be used to detect the external ambient light of the corresponding area of the display screen to obtain light sensation data, and then send the light sensation data to the processor 10 connected thereto.
Taking the example that the current display mode of the display screen 20 is the AOD mode, the processor 10 may compare the above light sensation data with a preset light sensation threshold, and when the light sensation data is less than or equal to the light sensation threshold, the processor 10 may indicate that the finger is detected to touch the display screen 20, that is, the processor 10 may determine that the first trigger operation is detected, that is, determine that the detected data meets the trigger condition, and at this time, the processor 10 may generate a mode switching instruction and adjust the electric potentials of the first voltage pin P1 and the second voltage pin P2.
The above light sensing threshold may be set according to a specific scene, for example, the light sensing threshold may be set to 0-0.5 in the case of a black box, and the light sensing threshold may be set to 3-10 in consideration of that light emitted by the display screen is reflected by a finger to be a part of external ambient light in the AOD display mode. For example, in a specific implementation, when the finger presses the display screen, the external ambient light is considered to be inevitably reduced, and then the light sensation data when the external ambient light is reduced to a certain degree is taken as a light sensation threshold value, or an average value of a plurality of historical light sensation data before the current light sensation data is compensated and then taken as the light sensation threshold value.
When the light sensation data is greater than the light sensation threshold, the processor 10 may further obtain a comparison result of the previous light sensation data of the current light sensation data and the light sensation threshold, and when the comparison result indicates that the previous light sensation data is less than or equal to the light sensation threshold, the operation that the finger leaves the display screen is detected, that is, the second triggering operation is detected. The processor 10 may determine that the detection data satisfies the trigger condition, generate a mode switching instruction, and adjust the potentials of the first voltage pin P1 and the second voltage pin P2. The processor may periodically poll and acquire light sensation data, for example, acquire light sensation data once every interval of time T, and each detection time is used as a detection node, where the previous light sensation data is the light sensation data detected by the detection node that is one time before the detection node that detects the current light sensation data.
It can be understood that, when the current display mode of the display screen 20 is the FOD mode, the first triggering operation is changed to the second triggering operation, and the principle of the triggering operation is opposite, which is not described herein.
Taking the pressure data obtained by taking the detection data as the pressure sensor as an example, the electronic device further includes a pressure sensor (not shown) disposed below the display screen 20, or the display screen is a touch-sensitive display screen. The pressure sensor may be used to detect pressure data of an external press of a corresponding area of the display screen and then send the pressure data to the processor 10 connected thereto.
Taking the example that the current display mode of the display screen 20 is the AOD mode, the processor 10 may compare the pressure data with the preset pressure threshold, and when the pressure data is greater than the pressure threshold, the processor 10 may determine that the finger touches the display screen 20, that is, the processor 10 may determine that the first trigger operation is detected, that is, determine that the detected data meets the trigger condition, and at this time, the processor 10 may generate a mode switching instruction and adjust the electric potentials of the first voltage pin P1 and the second voltage pin P2. The processor 10 may further obtain a comparison result of the previous pressure data of the current pressure data with the pressure threshold value when the pressure data is smaller than the pressure threshold value, and indicate that the operation of the finger leaving the display screen is detected, i.e. the second trigger operation is detected, when the comparison result indicates that the previous pressure data is larger than the pressure threshold value. The processor 10 may determine that the detection data satisfies the trigger condition, generate a mode switching instruction, and adjust the potentials of the first voltage pin P1 and the second voltage pin P2. And when the comparison result shows that the previous pressure data is smaller than the pressure threshold value, the detection that the finger does not touch the display screen, namely the first triggering operation is not detected. The processor may periodically poll to obtain pressure data, for example, obtain pressure data once every time interval t, and each time the pressure data is detected as a detection node, where the previous pressure data is pressure data detected by a detection node before the detection node that detects the current pressure data.
It can be understood that, when the current display mode of the display screen 20 is the FOD mode, the first triggering operation is changed to the second triggering operation, and the principle of the triggering operation is opposite, which is not described herein.
It should be noted that the electronic device may also be provided with an optical sensor and a pressure sensor at the same time, so that the detection data may include light sensing data and pressure data, and the processor may determine whether the detection data meets the triggering condition according to the light sensing data and the pressure data, respectively. In particular, a main component and another auxiliary component may be provided, so that when the judgment results conflict, the result determined by the detection data of the main component is used for processing.
In an example, the electronic device further includes a driving chip DDIC, which provides the pixel voltage and the gate switching signal required by each light emitting diode, and the specific working principle may refer to the related art, which is not described herein again. In this example, the processor 10 may supply power to the driving chip via the third power line AVDD through the third voltage pin P3.
The operation of the electronic device shown in fig. 3 will be described below, fig. 4 is a flowchart illustrating a process of controlling switching of display modes according to an exemplary embodiment, and fig. 5 is a waveform diagram illustrating a power supply timing of a processor according to an exemplary embodiment, see fig. 4 and 5:
in the case where the current display mode is the AOD mode, an optical sensor in the electronic device senses external ambient light in real time or periodically, obtains light sensation data, and transmits the light sensation data to the processor. After the processor obtains the light sensation data, the light sensation data can be compared with a preset light sensation threshold value; when the light sensation data is smaller than or equal to the light sensation threshold value, the processor can determine that the first trigger operation of the finger touching the display screen is detected, and determine that the light sensation data meets the trigger condition, otherwise determine that the light sensation data does not meet the trigger condition.
When it is determined that the light sensation data satisfies the trigger condition, the processor adjusts the potentials of the first voltage pin P1 and the second voltage pin P2, and a scenario in which the potential of P1 is kept unchanged is shown in fig. 5.
In one embodiment, a controller in the processor determines whether the light sense data satisfies a trigger condition, and when the trigger condition is satisfied, the controller sends a mode switching instruction to the power management unit. The power management unit acquires the voltage required by each light emitting diode in the display screen, and adjusts the potentials of the first voltage pin and the second voltage pin. The processor and the driving chip cooperate to provide the required positive and negative voltages for each light emitting diode, so that the effect of switching to a target switching mode, namely the FOD mode for display is achieved, namely a light spot area with higher brightness is displayed at a preset position in the display screen. Finally, the electronic device may detect the fingerprint of the finger by using the spot area, and operate by using the fingerprint to unlock, etc., and the scheme of unlocking by using the fingerprint may refer to the related technology, which is not described herein again.
In an embodiment, when the current display mode is the FOD mode, an optical sensor in the electronic device senses external ambient light in real time or periodically, obtains light sensation data, and sends the light sensation data to the processor. After the processor obtains the light sensation data, the light sensation data can be compared with a preset light sensation threshold value; when the light sensation data is larger than the light sensation threshold value and the previous light sensation data is smaller than or equal to the light sensation threshold value, the processor can determine that the second trigger operation of the finger leaving the display screen is detected, the light sensation data is determined to meet the trigger condition, and otherwise, the light sensation data is determined to not meet the trigger condition.
When the light sensation data is determined to meet the triggering condition, the processor adjusts the electric potential of the first voltage pin P1 and the electric potential of the second voltage pin P2, and the processor and the driving chip cooperate together to provide the required positive electrode voltage and the required negative electrode voltage for each light emitting diode, so that the effect of switching to the target switching mode, namely the AOD mode for displaying is achieved.
Therefore, in the embodiment of the disclosure, the first voltage pin and the second voltage pin can be preset on the processor, the first voltage pin is connected to the display screen through the first power line, the second voltage pin is connected to the display screen through the second power line, and thus the processor can adjust the power supply voltage of the display screen by adjusting the potentials of the first voltage pin and the second voltage pin, so that the display screen is switched from the current display mode to the target display mode. In this embodiment, the processor may directly output the voltage required by the display screen, so that the mode switching command and the voltage switch remain synchronous, and the current display mode and the target display mode are ensured to be reliably switched.
On the basis of the electronic device, the embodiment of the disclosure further provides a method for controlling display mode switching, referring to fig. 6, the method includes:
in step 61, detection data is acquired;
in step 62, when it is determined that the detection data meets the trigger condition, the electric potentials of the first voltage pin and the second voltage pin of the processor in the electronic device are respectively adjusted, so that the display screen is switched from the current display mode to the target display mode.
Alternatively, it may be determined whether the detected data satisfies the trigger condition by one of the following means: if a first trigger operation for indicating to switch to the target display mode is detected, determining that the detected data meets a trigger condition; and if the second trigger operation for indicating to exit the current display mode is detected, determining that the detection data meets the trigger condition.
Alternatively, it may be determined whether the detected data satisfies the trigger condition by one of the following means: determining whether a first trigger operation for instructing switching to the target display mode is detected; it is determined whether a second trigger operation for indicating to exit the current display mode is detected.
Optionally, the current display mode includes one of an AOD mode and an FOD mode, and the target display mode includes the other of the AOD mode and the FOD mode. Whether the first trigger operation or the second trigger operation is detected may be determined by one of: it is determined whether an operation of touching the screen by a finger or an operation of leaving the screen by a finger is detected.
Alternatively, whether the first trigger operation or the second trigger operation is detected may be determined by: acquiring light sensation data of external ambient light of a corresponding area of the display screen; comparing the light sensation data with a preset light sensation threshold value, and determining that the first trigger operation is detected when the light sensation data is smaller than or equal to the light sensation threshold value; and determining that the second trigger operation is detected when the light sensation data is greater than the light sensation threshold and the previous light sensation data of the light sensation data is less than or equal to the light sensation threshold.
Alternatively, whether the first trigger operation or the second trigger operation is detected may be determined by: acquiring pressure data when a corresponding area of the display screen is pressed; comparing the pressure data with a preset pressure data threshold, and determining that the first triggering operation is detected when the pressure data is smaller than or equal to the pressure data threshold; the second trigger operation is determined to be detected when the pressure data is greater than the pressure data threshold and a previous pressure data of the pressure data is less than the pressure data threshold.
According to the embodiment of the disclosure, the first voltage pin and the second voltage pin can be preset on the processor, the first voltage pin is connected to the display screen through the first power line, the second voltage pin is connected to the display screen through the second power line, and therefore the power supply voltage of the display screen can be adjusted by the processor through adjusting the potentials of the first voltage pin and the second voltage pin, and the display screen is switched from a current display mode to a target display mode.
