Description

Method for adjusting screen brightness and electronic equipment

Technical Field

The present disclosure relates to the field of electronic technologies, and in particular, to a method for adjusting screen brightness and an electronic device.

Background

Currently, smartphones or other electronic devices are taking an increasingly important position in the lives of users. In the using process of the electronic equipment, the screen brightness can be intelligently adjusted, the ambient light sensor of the electronic equipment is adopted to obtain the brightness of the external environment, and the brightness of the screen is adaptively adjusted according to the human eye vision model to obtain better user brightness experience.

However, when a user uses the electronic device, the user often shields the ambient light sensor with his hand, which causes the brightness of the screen to change repeatedly. Especially when the user uses the stylus pen to write, draw, create, the problem that screen brightness changes repeatedly is more obvious, has influenced user's writing, drawing, creation etc. to a certain extent, has influenced user experience. Therefore, how to intelligently adjust the screen brightness in the use process of the handwriting pen is a problem to be solved at present.

Disclosure of Invention

The application provides a method for adjusting screen brightness and electronic equipment, and the method can avoid the situation that the screen brightness changes repeatedly in the process of using a stylus by a user through adjusting the setting process of automatic brightness change.

In a first aspect, a method for adjusting screen brightness is provided, and is applied to an electronic device supporting a use scene of a stylus, and the method includes: detecting the brightness of a first environment, and displaying an interface of the electronic equipment with the brightness of a first screen; detecting that the first environmental light brightness changes into second environmental light brightness, wherein the numerical value of the second environmental light brightness is smaller than that of the first environmental light brightness; when the electronic equipment and the handwriting pen are detected to meet a first condition, displaying an interface of the electronic equipment with second screen brightness, wherein the first condition comprises at least one of the following conditions: the distance between the electronic equipment and the handwriting pen is smaller than or equal to a preset distance; the intensity of a first signal sent by the stylus pen received by the electronic equipment is greater than or equal to the preset signal intensity; or when detecting that the electronic equipment and the stylus meet a second condition, displaying an interface of the electronic equipment with third screen brightness, wherein the second condition comprises at least one of the following conditions: the distance between the electronic equipment and the handwriting pen is greater than the preset distance; the intensity of the signal sent by the stylus pen received by the electronic equipment is smaller than the preset signal intensity; the value of the second screen brightness is smaller than the value of the first screen brightness, and the value of the third screen brightness is smaller than the value of the second screen brightness.

It is to be understood that "first ambient light level" and "second ambient light level" are used only to indicate differences in ambient light levels. The ambient light brightness can be collected by the ambient light sensor, and the collected ambient light brightness information is transmitted to a processor (brightness adjusting module) of the electronic equipment, so that the current ambient light brightness is determined to be reduced.

It should also be understood that the stylus pen usage status of the electronic device may be determined according to a signal of the stylus pen acquired by a Touch Panel (TP) module. Alternatively, the TP module may correspond to a touch sensor of the electronic device, or correspond to a touch screen module (also referred to as a "touch panel module") composed of a touch sensor, a display screen module, and the like. It should be understood that the TP module may further include a peripheral circuit, which is not described herein again. In this application, the TP module is used for detecting the signal of the nib output of stylus. Specifically, the processor of the electronic device determines the suspension state and the contact state of the stylus pen according to the signal strength sent by the pen point of the stylus pen detected by the TP module, or determines whether the user has writing intention, and the like, which is not limited in the present application.

By the method, the processor (brightness adjusting module) can determine the final brightness of the screen by adopting different brightness adjusting algorithms according to different modes aiming at the use scenes of the user, such as the situation that the user uses the stylus pen and the scenes that the user does not use the stylus pen. The influence of the shielding of the body part caused by the use of the handwriting pen by the user on the brightness adjustment of the screen can be reduced, and the condition that the screen is dim and dim is avoided.

In a scene for a user to use the stylus pen, in order to prevent the situation that the screen brightness of the electronic device is dim, the application further provides multiple implementation modes, and the user can use the stylus pen and have better user experience by changing the adjusting period of the screen brightness, the adjusting rate of the screen brightness and the like.

With reference to the first aspect, in certain implementations of the first aspect, the first condition further includes at least one of: the value of the second ambient light brightness is less than or equal to a first threshold; the second ambient light level has a value less than or equal to the first threshold for a duration greater than or equal to a second threshold.

With reference to the first aspect and the foregoing implementations, in certain implementations of the first aspect, the second condition further includes at least one of: the value of the second ambient light brightness is less than or equal to a third threshold; the second ambient light level has a value less than or equal to the third threshold for a duration greater than or equal to a fourth threshold.

With reference to the first aspect and the foregoing implementation manners, in some implementation manners of the first aspect, the first threshold is less than or equal to the third threshold, and the second threshold is greater than or equal to the fourth threshold.

With reference to the first aspect and the foregoing implementations, in some implementations of the first aspect, the first threshold is zero.

In a scene that a user uses the stylus pen, for example, when the screen brightness adjusting module determines that the current mode is the stylus pen mode according to the signal intensity of the first signal between the stylus pen and the electronic device detected by the TP module, the screen brightness adjusting module adjusts the ambient light brightness trigger threshold to 0, so that repeated changes of the screen brightness in the scene that the stylus pen is used can be avoided.

It should be understood that when the ambient light triggering threshold is adjusted to 0 and the light intensity L of the ambient light is greater than 0, the condition for adjusting the screen brightness may not be satisfied, and the screen brightness remains unchanged.

According to the technical scheme, the trigger threshold value of the ambient light brightness is reduced, namely the trigger threshold of the screen darkening is reduced, the frequency of screen brightness adjustment is further reduced, and repeated changes of the screen brightness in the use scene of the stylus pen are avoided.

Or, the light intensity stabilization time threshold is increased, and when the duration t of the light intensity smaller than the ambient light brightness trigger threshold value is long enough, the screen brightness is adjusted, so that the non-long-time shielding behavior of a user can be avoided. In other words, when the shielding time of the user on the screen is less than the light intensity stabilization time threshold, the screen cannot be triggered to become dark, and false triggering caused by the unintentional action of the user is avoided, so that repeated changes of the screen brightness in the use scene of the stylus pen are avoided.

With reference to the first aspect and the foregoing implementation manners, in some implementation manners of the first aspect, when it is detected that the electronic device and the stylus pen satisfy a first condition, displaying an interface of the electronic device with a second screen brightness includes: when the electronic equipment and the handwriting pen are detected to meet the first condition, adjusting the first screen brightness to the second screen brightness at a first rate, and displaying an interface of the electronic equipment at the second screen brightness; and displaying the interface of the electronic equipment with third screen brightness when the electronic equipment and the stylus pen are detected to meet a second condition, wherein the method comprises the following steps: when the electronic equipment and the stylus are detected to meet the second condition, the first screen brightness is adjusted to the third screen brightness at a second rate, and the interface of the electronic equipment is displayed at the third screen brightness, wherein the first rate is smaller than the second rate.

According to the technical scheme, the screen dimming process is smoother and the stimulation to the vision of a user is reduced by increasing the time for adjusting the screen brightness or reducing the first speed value for adjusting the screen brightness.

In summary, the method for adjusting the screen brightness provided by the application can realize the intelligent adjustment of the screen brightness of the user in the use process of the stylus pen through the communication link between the stylus pen and the TP module and the cooperation of the ambient light sensor, the proximity light sensor and the like. Specifically, a current scene of using the stylus pen for the user is determined by detecting a distance between the stylus pen and the electronic device or a signal strength between the stylus pen and the electronic device; the situation that the screen brightness changes repeatedly in the handwriting pen using process of a user is avoided by adjusting the setting process of automatic brightness change in the handwriting pen scene.

For convenience of understanding, the following embodiments of the present application will specifically describe, by taking an electronic device having a structure shown in fig. 1 and fig. 2 as an example, a method for adjusting screen brightness provided by the embodiments of the present application with reference to the accompanying drawings and application scenarios.

In the using process of the electronic equipment, the brightness of the screen can be adjusted in a self-adaptive mode according to the ambient brightness of the electronic equipment. Specifically, the conventional screen adaptive brightness adjustment needs to acquire an ambient light brightness parameter acquired by an ambient light sensor of the electronic device, and according to the ambient light brightness parameter, when the ambient light brightness is low, the screen brightness is automatically reduced, so that a user can be prevented from feeling that the screen brightness is dazzling, and meanwhile, the product power consumption is reduced; when the ambient light brightness is strong, the screen brightness of the product needs to be synchronously improved to obtain a better visual effect.

For example, fig. 3 is a schematic diagram illustrating an example of adjusting the brightness of a screen, where an electronic device may adjust the brightness of the screen according to the ambient light brightness obtained by an ambient light sensor, and in particular, the method 300 is applied to the electronic device 100 including the ambient light sensor 10, the manual brightness bar adjusting module 20, and the brightness adjusting module 30.

As shown in fig. 3, the method 300 includes: (1) the ambient light sensor 10 acquires ambient light brightness in the environment, and transmits the ambient light brightness information to the brightness adjusting module 30 of the electronic device 100; (2) the user adjusts the screen brightness of the electronic device 100 by manually dragging a brightness bar (referred to as a "manual" brightness bar adjusting module in this application) displayed on the interface of the electronic device through the manual brightness adjusting module 20, and transmits the screen brightness information after the brightness bar adjustment to the brightness adjusting module 30 of the electronic device 100; (3) the brightness adjusting module 30 of the electronic device 100 determines the screen brightness according to the acquired ambient light brightness information and the screen brightness information of the brightness bar adjusting module 20 manually adjusted by the user, and uses the screen brightness as the final display brightness of the electronic device 100, that is, the screen brightness visible to the naked eye of the user.

It should be understood that the ambient light sensor 10 may correspond to 180L of the electronic device 100 described in fig. 1, the manual brightness bar adjustment module 20 may correspond to the display screen 194 of the electronic device 100 described in fig. 1, the display screen 194 may receive a touch operation of a user and transmit information of a user's manual dragging brightness bar adjustment to the processor 110, and the brightness adjustment module 30 may correspond to the processor 110 of the electronic device 100 described in fig. 1, determine a final screen brightness through the processor 110, and transmit the final screen brightness to the display screen module, and control the display screen module to display the final screen brightness, in other words, provide a visual output by the display screen 194, that is, a screen brightness visually visible to the user, which is not described herein again.

Since the ambient light sensor 10 has a certain receiving angle, according to the method 300 described above, when the electronic device adjusts the brightness of the screen only according to the ambient light brightness information acquired by the ambient light sensor 10 and by combining the brightness information of the manual brightness bar adjusting module 20, the ambient light sensor 10 cannot truly reflect the brightness of the environment where the electronic device is located, so that the screen brightness adjusted according to the brightness information of the environment where the electronic device is located does not necessarily meet the use requirement of the user.

In addition, the ambient light sensor 10 is generally disposed inside the electronic device, and in order to obtain light from the external environment, a hole needs to be formed in the electronic device. At present, in order to avoid the influence of the opening of the electronic device on the appearance of the electronic device, the opening is treated with ink, so as to further reduce the receiving angle of light. Therefore, when a user uses the stylus pen to write or draw on the display screen of the electronic device, the ambient light enters the ambient light sensor 10 due to the fact that the body parts such as the arms and the elbows block the ambient light, and then the screen brightness of the electronic device becomes dark when the user writes, which affects the user experience. Moreover, as the body part of the user moves during writing, the screen brightness of the electronic device may be suddenly and suddenly changed, and the user experience is poor.

In another possible implementation manner, in order to avoid frequent changes of the screen brightness caused by the shielding of the ambient light sensor by the body part of the user, the proximity light sensor may be used for auxiliary judgment.

For example, fig. 4 is a schematic diagram of another example of adjusting the brightness of a screen, and an electronic device may adjust the brightness of the screen according to the ambient light brightness acquired by the ambient light sensor 10, and in particular, the method 400 is applied to the electronic device 100 including the ambient light sensor 10, the manual brightness bar adjusting module 20, the brightness adjusting module 30, and the proximity light sensor 40. By setting the proximity of the layout positions of the proximity light sensor 40 and the ambient light sensor 10 of the electronic device 100, the proximity light sensor 40 detects whether the ambient light sensor 10 is blocked by a body part of the user or the like, which affects the collection of the ambient light information by the ambient light sensor 10.

As shown in fig. 4, the method 400 includes:

(1) when the proximity light sensor 40 detects the shielding state of the ambient light sensor 10, and when the ambient light sensor 10 is not shielded, the ambient light sensor 10 obtains the ambient light brightness in the environment, and transmits the ambient light brightness information to the brightness adjusting module 30 of the electronic device 100; when the proximity light sensor 40 detects that the ambient light sensor 10 is blocked, the ambient light information obtained by the current ambient light sensor 10 is automatically filtered out, in other words, the brightness adjusting module 30 does not obtain the current ambient light brightness information, and can continue to control the screen brightness determined based on the previously obtained ambient light brightness information.

(2) The user adjusts the screen brightness of the electronic device 100 by manually dragging the brightness bar of the electronic device through the manual brightness bar adjusting module 20, for example, the user manually drags the brightness bar of the electronic device, and transfers the screen brightness information after the brightness bar adjustment to the brightness adjusting module 30 of the electronic device 100.

(3) The brightness adjusting module 30 of the electronic device 100 determines the screen brightness according to the previously acquired ambient light brightness information and the screen brightness information of the brightness bar adjusting module 20 manually adjusted by the user, and uses the screen brightness as the final display brightness of the electronic device 100, that is, the screen brightness visible to the naked eye of the user. When the proximity light sensor 40 detects that the shielding object leaves, the brightness adjusting module 30 performs a function of adaptively adjusting the screen brightness according to the ambient light brightness information.

It should be appreciated that the proximity light sensor 40 shown in method 400 may determine whether an object is in proximity to the electronic device 100 by emitting light and receiving reflected light from nearby objects. For example, the proximity light sensor 40 may include a Light Emitting Diode (LED) and a light detector, such as an infrared light emitting diode. The infrared light emitting diode emits infrared light and receives infrared reflected light from a nearby object. The electronic apparatus 100 detects infrared reflected light from a nearby object using a photodiode, and when sufficient reflected light is detected, it can be determined that an object is in the vicinity of the electronic apparatus 100. When insufficient reflected light is detected, the electronic device 100 may determine that no object is in proximity to the electronic device 100.

Furthermore, in the method 400, the ambient light sensor 10 may correspond to 180L of the electronic device 100 described in fig. 1, the proximity light sensor 40 may correspond to 180G of the electronic device 100 described in fig. 1, the manual brightness bar adjustment module 20 may correspond to the display screen 194 of the electronic device 100 described in fig. 1, and the brightness adjustment module 30 may correspond to the processor 110 of the electronic device 100 described in fig. 1, wherein the processor processes the ambient light brightness of the ambient light sensor 10 to determine a final screen brightness, and the display screen 194 provides a visual output to provide a screen brightness that is visually visible to the user.

It should also be understood that when the brightness adjustment module 30 of the electronic device 100 determines the screen brightness, the ambient light brightness information may be periodically obtained from the ambient light sensor 10, for example, 1 time per second. If the proximity light sensor 40 detects that an object is close to or the ambient light sensor 10 is blocked, the ambient light brightness information may not be acquired any more, and the final screen brightness is determined according to the ambient light brightness information acquired last time and the manual adjustment of the user, which is not limited in the present application.

According to the method, after the proximity light sensor 40 is added, the screen brightness adjustment when the ambient light sensor 10 is shielded in the method 300 is optimized to a certain extent, however, the detection distance of the proximity light sensor 40 is short, and the detection angle is smaller than that of the ambient light sensor 10, so that the problem that the screen brightness is dim due to frequent shielding of the body part of the user on the ambient light sensor 10 in a handwriting pen using scene still cannot be solved, particularly for a high-intensity user using a handwriting pen, the problem that the screen brightness is dim still occurs, and the user experience is poor.

Aiming at the scenes, in order to solve the problem that the screen brightness repeatedly changes due to frequent shielding of body parts such as arms and elbows during the process of using the handwriting pen by a user, the method for adjusting the screen brightness is provided by the application.

For example, fig. 5 is a schematic diagram of an example of adjusting screen brightness according to an embodiment of the present disclosure, and in particular, the method 500 is applied to the electronic device 100 including the ambient light sensor 10, the manual brightness bar adjusting module 20, the brightness adjusting module 30, the proximity light sensor 40, and the Touch Panel (TP) module 50. The present application determines that the stylus is currently in the proximity state by combining information detected by the proximity light sensor 40, the ambient light sensor 10, and the TP module 50 of the electronic device 100, thereby adaptively adjusting screen brightness.

It should be understood that the TP module 50 may correspond to the touch sensor 180K of the electronic device 100 introduced in fig. 1, or correspond to a touch screen module (also referred to as a "touch panel module") composed of the touch sensor 180K and a display screen module, etc. It should be understood that the TP module 50 may further include peripheral circuits, which are not described in detail herein.

The TP module 50 may include a touch sensor 180K that may be disposed on a display screen of the electronic device 100, such that the TP module 50 may detect a touch operation applied thereto or thereabout and pass the detected touch operation to the application processor to determine the touch event type. For example, in the present application, the user dragging the manual intensity bar is passed to the processor, and visual output related to the touch operation may be provided via the display screen 194.

In addition, in scenarios where the stylus is used by a user, TP module 50 may also be used to detect signals output by the tip of the stylus. Specifically, the processor of the electronic device may determine the suspension state and the contact state of the stylus pen according to the signal strength sent by the pen point of the stylus pen detected by the TP module 50, or determine whether the user has writing intention, and the like.

It should be understood that in the present application, the signal output from the pen tip of the stylus pen is detected by the TP module 50, and the stylus pen and the electronic device 100 are in a pairing state, for example, pairing is achieved by means of bluetooth, and the TP module 50 can detect the signal output from the pen tip of the stylus pen. In addition, pairing can be achieved through the coil and an auxiliary pairing mode of the first signal, and the pairing mode of the stylus pen and the electronic device is not limited in the application.

During the user's in-service use handwriting pen, write thereby normally work through TP module 50 detection nib output's signal, in order to guarantee to write and experience, signal amplitude and the intensity of handwriting pen output can guarantee when pen and product interval certain distance, just can detect the handwriting pen.

It should also be appreciated that in the method 500, the ambient light sensor 10 may correspond to 180L of the electronic device 100 described in fig. 1, the proximity light sensor 40 may correspond to 180G of the electronic device 100 described in fig. 1, the manual intensity bar adjustment module 20 may correspond to the display screen 194 of the electronic device 100 described in fig. 1, and the intensity adjustment module 30 may correspond to the processor 110 of the electronic device 100 described in fig. 1, and the final screen intensity may be determined by the processor, and the visual output provided by the display screen 194, the screen intensity being visually perceptible to the user.

As shown in fig. 5, the method 500 includes:

(1) the ambient light sensor 10 acquires ambient light brightness in the environment and transmits the ambient light brightness information to the brightness adjustment module 30 of the electronic device 100.

Optionally, the brightness adjustment module 30 corresponds to a functional unit or a module in the processor 110 of the electronic device 100, and the brightness adjustment module 30 may process the ambient light to determine the ambient light brightness, and the application does not limit the processing process of the ambient light.

It should be understood that the brightness bar corresponds to a brightness interval, and after the user manually drags the brightness bar, the position on the brightness bar corresponds to a user-desired screen brightness value, and the user-desired screen brightness value is transmitted to the brightness adjustment module 30.

(3) The proximity light sensor 40 transmits energy of reflected light from a nearby object to the brightness adjustment module 30 of the electronic device 100 by emitting light and receiving the reflected light, and the brightness adjustment module 30 determines whether an object is in proximity to the electronic device 100 according to the energy of the reflected light of the nearby object.

Illustratively, the proximity light sensor 40 may include a Light Emitting Diode (LED) and a light detector, such as an infrared LED. The infrared light emitting diode emits infrared light and receives infrared reflected light from a nearby object. When the proximity light sensor 40 detects the infrared reflected light, the energy of the infrared reflected light can be transmitted to the brightness adjusting module 30, and the brightness adjusting module 30 determines that an object is in proximity, and the brightness adjusting module 30 can determine the distance that the object is in proximity according to the energy intensity of the received infrared reflected light, which is not described herein again.

(4) The TP module 50 detects the signal strength sent by the pen head of the stylus pen, and determines the state or mode of the stylus pen according to the detected signal strength, for example, the stylus pen is in a suspended state, or in a contact state, that is, the state of the user writing.

It should be understood that the TP module 50 may receive an electrical signal from the stylus, referred to as a first signal in this application, and determine a floating state or a contact state of the stylus or a distance between the stylus and the screen according to the strength of the first signal, and thus determine whether the stylus is in a close state or a far state, which is not limited in this application.

Fig. 6 is a schematic diagram of an example of interaction between a stylus pen and an electronic device according to an embodiment of the present application, and a manner of interaction between the stylus pen 60 and the electronic device 100 may be as shown in fig. 6. In fig. 6, the stylus 60 may be referred to as an "active capacitive stylus" (AES), the stylus 60 may include functional electrodes, such as a Receiver (RX) electrode and a Transmitter (TX) electrode, the RX electrode may receive a second signal sent by the TP module 50, and the TX electrode sends a first signal to the TP module 50, so as to determine whether the stylus is in a close state or a far state according to the strength of the first signal.

It should be understood that in the present application, the electrical signal transmitted from the electronic device 100 to the stylus 60 is referred to as a second signal, and the electrical signal transmitted from the stylus 60 to the electronic device 100 is referred to as a first signal. The first signal and the second signal are merely used for descriptive distinction and are not limited in this application.

Alternatively, the electrical signal such as the first signal and the second signal may be a voltage signal, which is not limited in this application.

Specifically, the stylus pen 60 has a function of processing the electrical signal, for example, the stylus pen 60 may filter and demodulate the received second signal; the stylus 60 also has a high voltage transmitting function, and generates an electrical signal to transmit to the TP module 50 of the electronic device 100. After the TP module 50 receives the first signal, the TP module may also filter and demodulate the received first signal to obtain an electrical signal that can determine the strength of the first signal. The TP module 50 determines the writing intention of the user according to the electrical signal.

Illustratively, the TP module 50 may determine the distance between the stylus 60 and the electronic device 100 based on the strength of the electrical signal. Alternatively, the distance may be a distance between the TX electrode and the screen of the electronic device 100, or a distance between the tip of the stylus 60 and the screen of the electronic device 100, which is not limited in this application.

Illustratively, the TP module 50 determines the writing intention of the user according to the distance between the stylus 60 and the electronic device 100, and the distance between the stylus 60 and the electronic device 100 is denoted as d. For example, in one possible implementation, when the TP module 50 determines that the distance d between the stylus 60 and the electronic device 100 is less than or equal to 5mm according to the strength of the first signal, it is determined that the stylus 60 is in the close state and the user has writing intention.

When the TP module 50 determines that the distance d between the stylus 60 and the electronic device 100 is d >5mm according to the strength of the first signal, it is determined that the stylus 60 is in the far state and the user has no writing intention.

(5) The brightness adjusting module 30 of the electronic device 100 determines an algorithm for adjusting the screen brightness according to the acquired ambient light brightness information and the screen brightness information of the brightness bar adjusting module 20 manually adjusted by the user in different handwriting modes according to the state or mode of the handwriting pen determined by the TP module 50, determines the final screen brightness, and uses the screen brightness as the final display brightness of the electronic device 100, that is, the screen brightness visible to the naked eye of the user.

Alternatively, for the case where the user has writing intention, the brightness adjustment module 30 may perform screen brightness adjustment in the stylus mode. For the case where the user has no writing intention, the brightness adjustment module 30 may perform the screen brightness adjustment in the non-stylus mode.

It should be understood that the handwriting mode and the non-handwriting mode described above are used to indicate that the brightness adjusting module 30 can adaptively adjust the brightness of the screen under different scenes by using different brightness adjusting algorithms. For example, in the case of writing intention for the user, the brightness adjustment module 30 may call a first brightness adjustment algorithm to adjust the screen brightness in the stylus mode; for the case that the user has no writing intention, the brightness adjustment module 30 may call the second brightness adjustment algorithm to perform the screen brightness adjustment in the non-handwriting mode. The first brightness adjusting algorithm and the second brightness adjusting algorithm are different algorithms.

In a possible implementation manner, when the user is in the handwriting pen using state, that is, in the handwriting pen mode, the brightness adjusting module 30 may reduce the abrupt change of the screen brightness by reducing the number of times of acquiring the ambient light brightness from the ambient light sensor 10.

Optionally, the brightness adjustment module 30 may also slow the rate of screen brightness change by slowing the speed of the brightness change.

For example, in the non-stylus mode, the period in which the ambient light sensor 10 collects the ambient light level is 20 times per minute, and in the stylus mode, the period in which the ambient light sensor 10 collects the ambient light level is 5 times per second.

Or, for example, the period of the ambient light sensor 10 collecting the ambient light brightness is 20 times per minute, in the non-handwriting mode, when the brightness adjusting module 30 determines that the ambient light brightness changes, the adjusting period of adjusting the screen brightness of the electronic device according to the change of the ambient light brightness is reduced to 5 times per minute, in the handwriting mode, the adjusting period of the brightness adjusting module 30 adjusting the screen brightness of the electronic device according to the change of the ambient light brightness is 1 time per second, and the speed of the brightness adjusting module 30 reducing the brightness change is not limited in the present application.

By the above method, the brightness adjusting module 30 may determine the final brightness of the screen according to different modes according to the use scenes of the user, for example, the situation that the user uses the stylus pen and the scenes that the user does not use the stylus pen. The influence of the shielding of the body part caused by the use of the handwriting pen by the user on the brightness adjustment of the screen can be reduced, and the condition that the screen is dim and dim is avoided.

In another possible implementation manner, in the handwriting mode, when the ambient light sensor 10 detects that there is a sudden change in the ambient light brightness, the screen brightness is locked for a certain time, that is, the brightness adjustment module 30 ensures that the screen brightness of the electronic device 100 remains unchanged for a certain time.

The above-described method of adjusting screen brightness may utilize the existing communication link between the stylus and the TP module 50 to determine the usage scenario and status of the user based on the conventional ambient light sensor 10 and proximity light sensor 40 schemes. The brightness adjusting module 30 can determine the suspension and contact states of the stylus pen according to the TP module 50, so as to effectively avoid the problem of variable screen brightness when the user writes the stylus pen, and improve the user experience of the stylus pen in the using process.

In another possible implementation manner, in a usage scenario of the stylus pen, the adjustment process of the screen brightness by the brightness adjustment module 30 is controlled by controlling the trigger threshold and the adjustment times of the screen brightness automatic adjustment.

Fig. 7 is a schematic diagram of an example of a brightness adjustment process according to an embodiment of the present application. As shown in fig. 7, the brightness adjustment process 700 includes:

an ambient light sensor 10 of the electronic device samples the ambient light 701.

The ambient light sensor 10 transmits the sampled ambient light to the brightness adjustment module 30, and the brightness adjustment module 30 performs light intensity filtering processing to obtain an ambient light signal with light intensity L.

It should be understood that the process of filtering the sampled ambient light may be performed by the ambient light sensor 10, or may be performed by the ambient light sensor 10 of the electronic device transmitting to the brightness adjusting module 30 of the electronic device, or may be performed by other functional units or modules in the processor 110 of the electronic device 100, which is not limited in this application.

703-1, setting an ambient light level trigger threshold L _ dark.

703, according to the triggering threshold L _ dark of the ambient light brightness of 703-1, the screen brightness adjusting module 30 determines whether the light intensity L of the ambient light signal is less than or equal to the triggering threshold L _ dark of the ambient light brightness.

704-1, setting a light intensity stabilization time threshold t₀。

704, when L in 703 is less than or equal to L _ dark, the light intensity according to 704-1 is stableTiming threshold t₀The screen brightness adjusting module 30 determines whether the duration t of the light intensity L less than or equal to L _ dark is greater than or equal to the light intensity stable time threshold t₀。

705-1, a first rate of screen brightness adjustment is set.

705, when t ≧ t in 704₀Then screen brightness adjustment module 30 adjusts the screen brightness to the final display brightness at the first rate of 705-1.

It is to be appreciated that prior to performing 705, screen brightness adjustment module 30 determines a final screen brightness based on the acquired ambient light brightness information, screen brightness information from user manually adjusted brightness bar adjustment module 20, etc. according to the method described in fig. 5 and 6, and finally adjusts the screen brightness to the final display brightness at the first rate according to the process described in fig. 7.

It should be further understood that the setting of the ambient light level triggering threshold L _ dark in 703-1, the setting of the light intensity settling time threshold t0 in 704-1, and the setting of the first rate of screen brightness adjustment in 705-1 can be preset by the screen brightness adjustment module 30, which is not limited in this application.

In the normal scene, for example, in a scene where the user does not use the stylus pen, in the process of automatically adjusting the screen brightness by the screen brightness adjusting module 30, the screen brightness may be adaptively adjusted according to the ambient light intensity, the duration of the ambient light intensity, and the adjustment rate of the screen brightness. Specifically, when the ambient light intensity L is lower than the dimming brightness trigger threshold L _ dark, and the duration t is larger than or equal to the light intensity stabilization time threshold t₀And controlling the screen brightness to be adjusted to the final display brightness at a first rate.

In one possible implementation, the frequency of screen brightness adjustment is further reduced by reducing the trigger threshold L _ dark for ambient light level in 703-1, i.e. reducing the trigger threshold for screen dimming, so as to avoid repeated screen brightness changes in the use scene of the stylus pen.

Alternatively, in a scene of using the stylus pen for the user, for example, when the screen brightness adjusting module 30 determines that the current mode is the stylus pen mode according to the signal strength of the first signal between the stylus pen and the electronic device detected by the TP module 50, the screen brightness adjusting module 30 adjusts the ambient light brightness trigger threshold L _ dark to 0, so that the repeated change of the screen brightness in the scene of using the stylus pen can be avoided.

It should be understood that when the ambient light level trigger threshold L _ dark is adjusted to 0 and the light intensity L of the ambient light is greater than 0, the condition for adjusting the screen brightness is not satisfied, and the screen brightness remains unchanged.

In another possible implementation, the time threshold t is stabilized by increasing the light intensity in 704-1₀。

It will be appreciated that when the light intensity settling time threshold t is increased₀When the duration time t of the light intensity L being less than or equal to L _ dark is long enough, the screen brightness is adjusted, so that the non-long-time shielding behavior of a user can be avoided. In other words, when the shielding time of the user on the screen is less than the light intensity stabilization time threshold t₀In the process, the screen cannot be triggered to become dark, and the false triggering caused by the unintentional behavior of a user is avoided, so that the repeated change of the screen brightness in the use scene of the stylus pen is avoided.

In another possible implementation, the process of dimming the screen is made smoother by increasing the time of the screen brightness adjustment in 705-1 or decreasing the first rate value of the screen brightness adjustment, reducing the stimulus to the user's vision.

It should be understood that when L ≦ L _ dark, and t ≧ t₀The screen brightness adjustment module 30 determines the final display brightness and adjusts the screen brightness to the final display brightness at a first rate. If the time for adjusting the screen brightness is increased or the first speed value for adjusting the screen brightness is reduced, the process of screen darkening is slower and smoother, and the perception of brightness change by the user is reduced, thereby reducing the stimulation to the vision of the user and improving the quality of the visionAnd (4) user experience.

Fig. 8 is a schematic composition diagram of an example of a screen brightness adjusting device according to an embodiment of the present application, where the screen brightness adjusting device 800 may be an electronic device such as the aforementioned mobile phone, and the electronic device supports a use scenario of a stylus pen. As shown in fig. 8, the electronic device may include: an ambient light sensor 10 for collecting ambient light brightness; a touch panel TP module 50, the TP module 50 capable of receiving a first signal transmitted by a stylus pen; a processor 810 and a memory 820. Optionally, the electronic device may also include a proximity light sensor 40.

It should be understood that the processor 810 may correspond to the brightness adjustment module 30 described above with reference to fig. 5 and 6.

The memory 820 may store one or more programs that, when executed by the processor 810, cause the electronic device 800 to perform the steps of:

and displaying the interface of the electronic equipment with first screen brightness when the first ambient light brightness is reached.

The ambient light sensor 10 collects ambient light brightness and transmits the collected ambient light brightness to the processor 810, and the processor 810 detects that the first ambient light brightness is changed into a second ambient light brightness, wherein the second ambient light brightness is smaller than the first ambient light brightness, that is, the ambient light brightness is reduced.

The TP module 50 may receive a first signal sent by a stylus pen, transmit the first signal to the processor 810, and adjust the first screen brightness to a second screen brightness when the processor 810 determines that the electronic device is in a stylus pen use state according to the first signal, so as to display an interface of the electronic device with the second screen brightness;

or, when the processor 810 judges that the electronic device is not in the stylus pen using state according to the first signal, adjusting the first screen brightness to a third screen brightness, and displaying an interface of the electronic device with the third screen brightness.

The numerical value of the second screen brightness is smaller than the numerical value of the first screen brightness, and the numerical value of the third screen brightness is smaller than the numerical value of the second screen brightness.

In one possible implementation, processor 810 may detect that the electronic device is in a stylus pen using state according to TP module 50, and may adjust from the first screen brightness to a second screen brightness according to a duration that a value of the second ambient light brightness detected by the ambient light sensor is less than or equal to a first threshold and/or a value of the second ambient light brightness is less than or equal to the first threshold and is greater than or equal to a second threshold.

Alternatively, in another possible implementation manner, the processor 810 may detect that the electronic device is not in a stylus pen using state according to the TP module 50, and may adjust the first screen brightness to a third screen brightness according to a duration that the value of the second ambient light brightness detected by the ambient light sensor is less than or equal to a third threshold, and/or the value of the second ambient light brightness is less than or equal to the third threshold and is greater than or equal to a fourth threshold.

Optionally, the first threshold is less than or equal to the third threshold, and the second threshold is greater than or equal to the fourth threshold.

Illustratively, the first threshold may be zero. When the first threshold is set to be zero, in a handwriting pen using scene, the electronic equipment can control the screen brightness to be kept unchanged, so that the situation that the screen brightness repeatedly changes in the handwriting pen using process of a user is avoided, the screen writing experience of the user in the handwriting pen using process is optimized, the use efficiency of the handwriting pen as a productivity tool and the comfort in the use process are improved, the user is more willing to use the handwriting pen to create, and the user experience is improved.

In one possible implementation, processor 810 may adjust from the first screen brightness to the second screen brightness at a first rate according to TP module 50 detecting that the electronic device is in a stylus use state.

Alternatively, in another possible implementation manner, processor 810 may adjust the first screen brightness to the third screen brightness at a second rate according to a detection by TP module 50 that the electronic device is not in a stylus use state, where the first rate is smaller than the second rate.

According to the scheme, the speed of brightness change is reduced, the speed of screen brightness change is slowed down, the process of screen dimming is smoother, and stimulation to the vision of a user is reduced.
