Description
Technical Field
The present disclosure relates to the field of control technologies, and in particular, to a method and an apparatus for controlling display mode switching, an electronic device, and a storage medium.
Background
Currently, some smart phones are provided with an underscreen fingerprint unlocking function. When the fingerprint unlocking function is started, a highlight area is formed in a finger pressing area of a display screen of the smart phone, and the display screen works in an FOD (finger print on display) mode at the moment. Then, detecting the highlighted area may obtain the fingerprint of the finger and unlock the display screen.
Referring to fig. 1, a smart phone in the related art adopts the following power supply scheme:
when the mode is switched from the normal display mode (AOD) to the FOD mode, the processor AP sends a mode switching instruction to the driver chip DDIC, and the driver chip DDIC sends a switch control signal to the power management chip PMIC, so as to achieve the effect of controlling the voltage of the light emitting diode.
However, the inventors found that: referring to fig. 2, the processor AP sends a mode switching command to the driver chip DDIC, and at least waits for one frame, that is, there is a time delay t 3; the driving chip DDIC sends out the wire control signal until the voltage switching is completed, and at least the time of waiting for another frame is needed, that is, there is a time delay t 4; the driving chip DDIC sends out SWIRE control signals to the power management chip PMIC to control the voltage switching. Thus, in a scenario of fast switching between the AOD mode and the FOD mode, if the mode switching command is too fast, the mode switching command may occur within a delay time period, so that the PMIC switching voltage of the power management chip is not timely, resulting in an error that the AOD mode is high brightness or the FOD mode is low brightness.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
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 voltage switching. For example, when the switching command occurs in a delayed time period, the power management chip PMIC switching voltage is not timely, which may cause an error that the AOD mode is high brightness or the FOD mode is low brightness.
In order to solve the above technical problem, 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 20. The processor 10 includes a preset first voltage pin P1 and a preset second voltage pin P2, the first voltage pin P1 of the processor 10 is connected to the display screen 20 through a first power line (e.g., which may be labeled as ELVDD); the second voltage pin P2 of the processor 10 is connected to the display screen 20 via a second power line (e.g., which may be labeled ELVSS).
And the processor 10 is used for adjusting the potentials of the first voltage pin P1 and the second voltage pin P2 so that the display screen 20 is switched from the current display mode to the target display mode according to the potentials on the first power line and the second power line.
In one 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 one example, processor 10 includes a controller 11 and a power management unit 12. The controller 11 may be implemented by a microprocessor, a digital processing chip, or a chip or a circuit with a processing function, such as a single chip, and is configured to send a mode switching instruction to the power management unit 12 when a trigger condition is met. 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 by the target display mode according to the mode switching command, and adjust the potentials of the first voltage pin P1 and the second voltage pin P2 according to the required voltage. During specific implementation, the power management unit can also preset the required potential in the target display mode, and when a mode switching instruction is received, the required potential can 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 when packaged, thereby facilitating subsequent electrical connection.
In an example, the processor 10 may also acquire the detection data before determining to adjust the potentials of the first and second voltage pins P1 and P2, and determine whether to adjust the potentials of the first and second voltage pins P1 and P2 based on whether the detection data satisfies the trigger condition. The detection data meeting the trigger condition may include any one of the following: a first trigger operation for instructing switching to a target display mode is detected, and a second trigger operation for instructing exiting from a 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; namely, switching from the current display mode to the target mode includes: switching from the AOD mode to the FOD mode or switching from the FOD mode to the AOD mode. In this example, the first trigger 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 trigger operation may include 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 include a component for acquiring the detection data, such as an optical sensor, a pressure sensor, or an operation key, and the technician may set the component according to a specific scenario, which is not limited herein.
Taking the sensed data as the light sensing data obtained by the optical sensor as an example, the electronic device may further include an optical sensor (not shown) disposed below the display screen 20. The optical sensor can be used for detecting external environment light in a corresponding area of the display screen to obtain light sensing data, and then sending the light sensing data to the processor 10 connected with the light sensing data.
Taking the current display mode of the display panel 20 as the AOD mode as an example, the processor 10 may compare the light sensing data with a preset light sensing threshold, and when the light sensing data is smaller than or equal to the light sensing threshold, it indicates that the operation of touching the display panel 20 by a finger is detected, that is, the processor 10 may determine that the first trigger operation is detected, that is, it determines that the detected data satisfies the trigger condition, and at this time, the processor 10 may generate a mode switching instruction and adjust the potentials of the first voltage pin P1 and the second voltage pin P2.
The light sensation threshold may be set according to a specific scene, for example, the light sensation threshold may be set to 0-0.5 in the case of a black box, and considering that light emitted from the display screen may be reflected by a finger to become a part of external environment light in the AOD display mode, the light sensation threshold may be set to 3-10, and it is understood that the above setting is merely exemplary. For another example, in a specific implementation, considering that when a finger presses a display screen, external ambient light inevitably decreases, the light sensation data that decreases to a certain degree is used as the light sensation threshold, or the average value of a plurality of historical light sensation data before the current light sensation data is compensated and used as the light sensation threshold.
When the light sensation data is greater than the light sensation threshold, the processor 10 may further obtain a comparison result between 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, it indicates that the operation of the finger leaving the display screen is detected, that is, the second trigger 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 and second voltage pins P1 and P2. The processor may periodically poll the light sensing data, for example, the light sensing data is acquired at intervals T, each time the light sensing data is detected as a detection node, and the previous light sensing data is the light sensing data detected by the previous detection node before the detection node that detects the current light sensing data.
It can be understood that, when the current display mode of the display screen 20 is the FOD mode, the first trigger operation is changed to the second trigger operation, and the principle of the trigger operation is opposite, which is not described herein again.
Taking the detected data as pressure data obtained by the pressure sensor as an example, the electronic device further includes a pressure sensor (not shown in the figure) 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 external pressure on a corresponding area of the display screen and then transmit the pressure data to the processor 10 connected thereto.
Taking the current display mode of the display screen 20 as the AOD mode as an example, the processor 10 may compare the pressure data with a preset pressure threshold, and when the pressure data is greater than the pressure threshold, it indicates that the operation of touching the display screen 20 by a finger is detected, that is, the processor 10 may determine that the first trigger operation is detected, that is, it is determined that the detected data satisfies the trigger condition, and at this time, the processor 10 may generate the mode switching instruction and adjust the potentials of the first voltage pin P1 and the second voltage pin P2. When the pressure data is smaller than the pressure threshold, the processor 10 may further obtain a comparison result between previous pressure data of the current pressure data and the pressure threshold, and when the comparison result indicates that the previous pressure data is larger than the pressure threshold, it indicates that the operation of moving the finger away from the display screen is detected, that is, the second trigger 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 and second voltage pins P1 and P2. When the comparison result indicates that the previous pressure data is smaller than the pressure threshold value, the condition that the finger does not touch the display screen is detected, namely the first trigger operation is not detected. The processor may periodically poll to obtain the pressure data, for example, obtain the pressure data once every time interval t, and obtain the pressure data once every time of detection as a detection node, where the previous pressure data is the pressure data detected by the previous detection node before the detection node that detected 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 trigger operation is changed to the second trigger operation, and the principle of the trigger operation is opposite, which is not described herein again.
It should be noted that, the electronic device may further include an optical sensor and a pressure sensor, so that the detection data may include light sensing data and pressure data, and the processor may determine whether the light sensing data and the pressure data satisfy the trigger condition according to the light sensing data and the pressure data, respectively. In specific implementation, one main component and the other auxiliary component can be further arranged, so that when judgment results conflict, the results determined by the detection data of the main component are processed.
In an example, the electronic device further includes a driving chip DDIC, and the driving chip provides a pixel voltage and a gate switching signal required by each light emitting diode. In this example, the processor 10 may supply power to the driving chip through the third power line AVDD through the third voltage pin P3.
The operation of the electronic device shown in fig. 3 is described below, fig. 4 is a flowchart illustrating a process of controlling display mode switching according to an exemplary embodiment, and fig. 5 is a waveform diagram illustrating a processor power timing according to an exemplary embodiment, referring to fig. 4 and 5:
when the current display mode is the AOD mode, an optical sensor in the electronic device senses external ambient light in real time or periodically to obtain light sensing data, and sends the light sensing 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, the processor can determine that a first trigger operation that a finger touches the display screen is detected, determine that the light sensation data meets the trigger condition, and otherwise determine that the light sensation data does not meet the trigger condition.
When it is determined that the light sensing 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 of keeping the potential of P1 constant is shown in fig. 5.
In one embodiment, a controller in the processor determines whether the light-sensing data meets a trigger condition, and when the trigger condition is met, the controller sends a mode switching instruction to the power management unit. The power supply 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 with each other to provide required anode and cathode voltages for each light emitting diode, so that the effect of switching to a target switching mode, namely an FOD mode, is achieved, namely, a light spot area with higher brightness is displayed at a preset position in the display screen. Finally, the electronic device can detect the fingerprint of the finger by using the light spot area, and perform operations such as fingerprint unlocking and the like, and the related technology can be referred to in the scheme of fingerprint unlocking, which is not described in detail herein.
In one embodiment, when the current display mode is the FOD mode, the optical sensor in the electronic device senses external ambient light in real time or periodically to obtain light sensing data, and sends the light sensing 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 and the previous light sensation data is smaller than or equal to the light sensation threshold, the processor can determine that a second trigger operation that the finger leaves 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 the light sensing data meet the triggering conditions, the processor adjusts the potentials of the first voltage pin P1 and the second voltage pin P2, and the processor and the driving chip cooperate to provide the required anode voltage and cathode 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 present disclosure, a first voltage pin and a second voltage pin may be preset on the processor, the first voltage pin is connected to the display screen through a first power line, and the second voltage pin is connected to the display screen through a second power line, so that the processor may adjust the power supply voltage of the display screen by adjusting the potentials of the first voltage pin and the second voltage pin, so as to switch the display screen 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 instruction and the voltage switching are kept synchronous, and the current display mode and the target display mode are reliably switched.
On the basis of the above electronic device, an embodiment of the present disclosure further provides a method for controlling display mode switching, referring to fig. 6, where the method includes:

in step 62, when it is determined that the detection data meets the trigger condition, adjusting the potentials of a first voltage pin and a second voltage pin of a processor in the electronic device, respectively, so as to switch the display screen from the current display mode to the target display mode.
Optionally, whether the detection data meets the trigger condition may be determined by one of the following ways: if a first trigger operation for indicating switching to the target display mode is detected, determining that the detection data meets a trigger condition; and if a second trigger operation for indicating to exit the current display mode is detected, determining that the detection data meets a trigger condition.

Optionally, whether the first trigger operation or the second trigger operation is detected may be determined by: acquiring pressure data when a corresponding area of a display screen is pressed; comparing the pressure data with a preset pressure data threshold, and determining that the first trigger operation is detected when the pressure data is smaller than or equal to the pressure data threshold; determining that the second trigger operation is detected when the pressure data is greater than the pressure data threshold and a previous one of the pressure data is less than the pressure data threshold.
