Glare is a poor lighting phenomenon that can cause the user's vision to be unrecognizable or uncomfortable. The glare exists in the lighted place, the general light adaptability glare (dark-light conversion) can be relieved for a long time, but if the glare is not controlled, the vision can be reduced when the user works and learns in the glare environment for a long time. For infants and old people, the damage caused by glare is likely to be changed into irreversible damage because of the tender retina or the reduced metabolic function and the gradual aging of the crystalline lens.

Glare can be classified into direct glare and reflected glare according to sources. The direct glare can be sunlight, lamp light of a vehicle coming from the opposite party at night, light generated by a highlight display screen and the like; the reflected glare can be light reflected on the surface of a wall, a water surface, a mirror surface and the like. It is found that when the brightness of the display screen is higher, the light emitting area is larger, the environment brightness is lower, the distance between the display screen and human eyes is closer, the projection direction of the light source is closer to the visual axis, and the glare generated by the display screen is more remarkable.

In the prior art, a user can improve glare generated by a display screen of an electronic device by adjusting the brightness of ambient light. However, when the glare generated by the display screen is improved by adopting a method of adjusting the brightness of the ambient light, an apparatus for generating the ambient light needs to be additionally arranged in the environment, and the method is hardly realized for a scene using the electronic equipment in a public place.

The user may also improve glare produced by the display screen of the electronic device by adjusting the screen brightness of the display screen. However, when glare generated from a display screen is improved by adjusting the brightness of the screen, the brightness of the screen is reduced, thereby reducing the display effect of the screen.

To this end, an embodiment of the present application provides a method for controlling an electronic device, where the method is applied to an electronic device, and the method includes: after the electronic equipment obtains the glare parameters including the distance between the electronic equipment and the user, the ambient light brightness, the current screen angle and the like, determining the current glare value, and when the current glare value is determined to be larger than the glare threshold value, controlling the screen angle of the electronic equipment to be adjusted to the target screen angle after determining the target screen angle according to one or more of the distance between the electronic equipment and the user, the ambient light brightness and the current screen brightness and the glare threshold value. Therefore, the screen angle of the electronic equipment is adjusted, so that the display screen of the electronic equipment after adjustment does not generate glare any more, and the use effect of a user is improved.

Fig. 2 is a schematic structural diagram of another electronic device according to an embodiment of the present application.

The control module 212 may control the rotating motor 240 to drive the connecting shaft to rotate so as to adjust the screen angle of the electronic device.

The method according to the embodiment of the application is exemplified by taking the electronic device as a notebook computer.

In one scenario, it is assumed that the initial state of the notebook computer is a closed state, i.e., the screen angle in the initial state is 0 °. After a user manually opens the screen of the screen computer to a certain angle (such as 60 degrees or 70 degrees) and the notebook computer detects that the user voice controls the notebook computer to open the anti-dazzle mode, the notebook computer is controlled to open the anti-dazzle mode in response to the voice control operation. After the notebook computer starts the anti-dazzle mode, the notebook computer acquires the current screen angle acquired by the angular velocity sensor. The notebook computer determines that the current screen angle is not within the preset angle range, and controls the rotating motor to drive the connecting shaft to rotate, so that the screen angle is adjusted to be within the preset angle range, for example, the notebook computer controls the current screen angle to be adjusted to 90 degrees.

Assuming that the notebook computer determines that the current glare value is greater than the glare threshold when the notebook computer controls the current screen angle to be adjusted to 90 °, the notebook computer may determine that the target screen angle is 118 ° according to one or more of a distance between the notebook computer and a user, an ambient light level, and the current screen brightness, and the glare threshold. The notebook computer controls the current screen angle to be adjusted to 118 degrees.

In another scenario, assume that a user uses a notebook computer in a certain scenario, and the notebook computer determines that the display screen is not producing glare in the scenario. After a user moves the notebook computer to another scene, the notebook computer detects that the brightness of the environment light is weakened, and the notebook computer evaluates that the influence of glare generated by a display screen on eyes of the user is large. In this case, the notebook computer can adjust the screen angle, so that the influence of glare generated by the display screen of the electronic device on eyes of a user is reduced after the screen angle is adjusted.

The technical solutions involved in the following embodiments may be implemented in an electronic device having the above-described hardware structure. The control method of the electronic device according to the embodiment of the present application is specifically described below with reference to fig. 3 to 5.

Assuming that the initial state of the electronic device is a screen closed state, that is, the screen angle is 0 ° in the initial state, the user can manually open the screen of the electronic device to a certain angle. In the process that the user uses the electronic equipment, the electronic equipment detects the triggering operation of opening the anti-dazzle mode by the user, and responds to the triggering operation of the user, the anti-dazzle mode is opened.

For example, the electronic device detects a trigger operation of a user voice instruction to turn on the antiglare mode, and turns on the antiglare mode in response to the user voice instruction.

Further exemplary, the electronic device detects a trigger operation that a user manually instructs to turn on the antiglare mode, and turns on the antiglare mode in response to the trigger operation by the user. As shown in fig. 3, when the electronic device detects a user's trigger operation of the switch control 302 in the interface 301, the electronic device turns on the antiglare mode in response to the user's trigger operation.

In the embodiment of the application, after the electronic equipment starts the anti-dazzle mode, the electronic equipment can determine the current glare value generated by the light source of the display screen, and then determine whether to adjust the screen angle of the electronic equipment according to whether the current glare value affects eyes of a user.

It will be appreciated that the determination of the current glare value by the electronic device is determined based on one or more of the parameters of the distance between the electronic device and the user, the ambient light level in which the electronic device is located, the screen brightness, and the screen angle. When the screen angles of the electronic equipment are different, the angles of the corresponding display screen light sources in the eye directions of the user are also different. Therefore, the electronic equipment can change the angle of the display screen light source in the eye direction of the user in a mode of adjusting the screen angle so as to improve the influence of glare generated by the display screen on the eyes of the user.

Fig. 4 is a schematic flow chart of a control method of an electronic device according to an embodiment of the present application, and a detailed description is given below of how to adjust a screen angle of the electronic device according to a current glare value with reference to fig. 4. As shown in fig. 4, the method may include steps 401 to 410.

In step 401, the electronic device turns on an antiglare mode in response to a trigger operation by a user.

In one possible scenario, after the electronic device turns on the anti-glare mode, the electronic device may obtain the current screen angle acquired by the angle sensor. When the electronic device determines that the current screen angle is within the preset angle range, the electronic device determines to continue to execute the subsequent step 402.

The current screen angle refers to an internal opening and closing angle of the electronic device. The first preset angle is a preset minimum angle value which can be used by a user normally. For example, the first preset angle may be 80 °, 90 °, and so on.

It can be understood that, after the electronic device starts the anti-dazzle mode in response to the triggering operation of the user, the electronic device determines that the screen angle is smaller than the first preset angle, and in this case, the user cannot normally use the electronic device, even if the display screen of the electronic device generates glare, the influence on eyes of the user is weak. Thus, in one possible scenario, the electronic device determines that the current screen angle is greater than the first preset angle, and the electronic device performs a process of adjusting the screen angle of the electronic device in real time according to the current glare value.

In another possible scenario, the electronic device performs step 402 immediately after the electronic device turns on the anti-glare mode.

It is understood that, during the use of the electronic device by the user, the glare generated by the light source of the display screen affects the eyes of the user as long as the user views the display screen. Accordingly, regardless of whether the current screen angle of the electronic device is the first preset angle, the electronic device immediately performs step 402 after determining to turn on the anti-glare mode.

Step 402, the detection module collects parameter values corresponding to the glare parameters.

The glare parameters include, but are not limited to, the distance between the electronic device and the user, the ambient light level in which the electronic device is located, the screen brightness, and the screen angle. The distance between the electronic device and the user may be the distance between the center position of the display screen of the electronic device and the eyes of the user, or the distance between the center position of the display screen and the eyes of the user. The ambient light level in which the electronic device is located may be an average or maximum brightness of the entire environment that produces the same illuminance on the vertical plane of the user's eyes without considering the influence of the glare source in the field of view, which is not limited herein. The screen brightness refers to the intensity of surface luminescence of the display screen. The screen angle refers to an internal opening and closing angle of the electronic equipment.

In the embodiment of the application, the electronic equipment can determine the distance between the electronic equipment and the user, the ambient light brightness, the screen angle and other parameter values corresponding to the glare parameters of the electronic equipment through the detection module.

By way of example, the detection module of the electronic device may include a position detector, a light sensor, a backlight controller, and an angle sensor. The detection module can acquire the distance between the electronic equipment and a user through the position detector, acquire the ambient light brightness of the electronic equipment through the light sensor, acquire the pulse width modulation (pulse width modulation, PWM) duty ratio value through the backlight controller so as to calculate and obtain the screen brightness and acquire the screen angle through the angle sensor.

In some embodiments, a position detector may be disposed in the electronic device, and the detection module may collect a distance between the electronic device and the user through the position detector. The position detector may be an ultrasonic sensor, an infrared sensor, a camera ranging sensor, etc., and the type of the position detector is not limited in the embodiment of the present application.

For example, assuming that the position detector is an ultrasonic sensor, the ultrasonic sensor transmits ultrasonic waves into a preset area range, the ultrasonic waves are transmitted to a user and immediately reflected back to the ultrasonic sensor, and the ultrasonic sensor obtains the distance between the electronic device and the user by calculating the time difference between the transmission and the return of the ultrasonic waves. Assuming that the propagation speed of the ultrasonic wave in the air is 340m/s, the ultrasonic sensor determines that the time difference between the sending and returning of the ultrasonic wave is t, and the distance s between the electronic equipment and the user can be calculated, namely: s=340×t/2.

In some embodiments, a light sensor may be disposed in the electronic device, and the detection module may collect the ambient light brightness of the electronic device through the light sensor. For example, at least two light sensors are disposed in the electronic device, and the detection module may determine a maximum value of the ambient light intensities collected by the at least two light sensors as the ambient light intensity where the electronic device is located. Or the detection module can determine the average value of the ambient light brightness collected by at least two light sensors as the ambient light brightness where the electronic equipment is located.

It should be explained that, when a plurality of light sensors are disposed in the electronic device, the plurality of light sensors may be disposed on the front side of the electronic device, may be disposed on the back side of the electronic device, or may be disposed on both the back side and the front side of the electronic device.

In some embodiments, a backlight controller may be disposed in the electronic device, and the detection module may obtain the PWM duty cycle value through the backlight controller. Then, the detection module may determine a product value of the PWM duty ratio value and the screen maximum brightness value as the screen brightness of the electronic device after acquiring the screen maximum brightness value of the electronic device stored in advance from the storage module. For example, assuming that the PWM duty ratio value obtained by the detection module through the backlight controller is a, the obtained maximum brightness value L of the screen, the detection module determines that the screen brightness is l×a.

In some embodiments, an angle sensor may be connected to the spindle of the electronic device to acquire the screen angle of the electronic device in real time. Therefore, the detection module can acquire the screen angle of the electronic device in real time through the angle sensor. For example, when the screen of the electronic device is in the closed state, the count value of the angle sensor is 0, and the screen angle of the electronic device is 0. When the rotating shaft of the electronic equipment rotates for 1/16 turn, the angle sensor counts once, and when the rotating shaft rotates in one direction, the count of the angle sensor is increased, and the accumulated count value is the screen angle value. When the rotation direction of the rotating shaft of the electronic equipment is changed, the count of the angle sensor is reduced every 1/16 turn of the rotating shaft, and the accumulated count value is the screen angle value.

Step 403, the detection module sends parameter values corresponding to the glare parameters to the verification module; correspondingly, the verification module receives a parameter value corresponding to the glare parameter.

In step 404, the verification module obtains the preset parameters from the storage module.

The preset parameters comprise a screen luminous area and a constant Goss position index. The screen light emitting area may be a display screen area of the electronic device.

In the embodiment of the application, the screen light emitting area and the constant Goss position index of the electronic equipment are prestored in the storage module, and the verification module can acquire the screen light emitting area and the constant Goss position index from the storage module.

It should be noted that, in the embodiment of the present application, the execution process of the step 403 and the step 404 is not limited, and the step 403 may be executed first, then the step 404 may be executed first, then the step 403 may be executed, and then the step 403 and the step 404 may be executed simultaneously.

Step 405, the verification module determines the current glare value according to the parameter value corresponding to the glare parameter and the preset parameter.

In order to quantitatively evaluate the glare produced by the display screen of the electronic device in the embodiment of the present application, a unified glare value (unifled GLARE RATING, UGR) proposed by the international lighting standard may be used as an evaluation criterion, where possible. The unified glare value UGR is a psychological parameter that measures the subjective reaction of the human eye to emitted light in a visual environment of a display screen of an electronic device. The verification module determines the current glare value as a unified glare value according to the parameter value corresponding to the glare parameter and the preset parameter.

When the environment light brightness, the screen brightness and the screen angle of the electronic equipment are unchanged, the larger the distance between the electronic equipment and the user is, the smaller the unified glare value determined by the electronic equipment is, and the smaller the influence of the glare generated by the display screen on eyes of the user is.

When the distance between the electronic equipment and the user, the screen brightness and the screen angle of the electronic equipment are unchanged, the larger the ambient light brightness of the electronic equipment is, the smaller the unified glare value determined by the electronic equipment is, and the smaller the influence of the glare value generated by the display screen of the electronic equipment on the user is.

When the distance between the electronic equipment and the user, the ambient light brightness where the electronic equipment is positioned and the screen angle of the electronic equipment are unchanged, the larger the value corresponding to the screen brightness of the electronic equipment is, the smaller the unified glare value determined by the electronic equipment is, and the larger the influence of the glare value generated by the display screen of the electronic equipment on the user is.

When the distance between the electronic equipment and the user, the ambient light brightness where the electronic equipment is positioned and the screen brightness are all unchanged, the glare value generated by the display screen of the electronic equipment is related to the screen angle of the electronic equipment.

As one possible implementation manner, the verification module of the electronic device may determine, according to the distance between the electronic device and the user and the current screen angle, after determining the second solid angle, the verification module determines a first product value of the square value of the current screen brightness and the second solid angle, and then determines a second product value of the first product value and the first fixed value. And then, after the verification module determines a first ratio of the second product value to the ambient light brightness, determining that the product of the logarithm of the first ratio and the second fixed value is the current glare value.

When the verification module determines the second solid angle according to the distance between the electronic device and the user and the current screen angle, the verification module can determine a third product value of the cosine value of the current screen angle and the screen light emitting area, and then determine the ratio of the third product value to the square value of the distance between the electronic device and the user as the second solid angle.

For example, the unified glare value UGR may be calculated using the following formula (1).

Formula (1)

Wherein UGR is the unified glare value,R is the distance between the electronic device and the user,For the ambient light level in which the electronic device is located,For screen brightness andFor adjusting the angle (i.e. the angle difference between the screen angle and the fixed angle), for example, the fixed angle may be 90 °, a is the screen light emitting area of the electronic device, P is a constant gauss position index, and p=1, ω represents the solid angle formed by the light emitting portion of the display screen to the human eye, in degrees of sphere (steradian, sr).

In the embodiment of the application, after the verification module receives the parameter value corresponding to the glare parameter sent by the detection module and acquires the preset parameter from the storage module, the verification module can calculate the unified glare value according to the parameter value corresponding to the glare parameter and the preset parameter by combining the formula (1).

In step 406, the verification module determines whether the current glare value is greater than a glare threshold.

When UGR values generated by display screens of electronic devices are different, the degree of glare perceived by human eyes is also different. By way of example, examples of UGR values and the degree of glare that can be perceived by the human eye are shown in table 1 below.

TABLE 1

As can be seen from table 1, the larger the current UGR value estimated by the electronic device, the larger the influence of the glare generated by the display screen of the electronic device on the eyes of the user in the actual use process of the electronic device. Therefore, in the embodiment of the application, the electronic equipment is preset with a glare threshold value, and the glare threshold value is used for measuring the influence of the glare generated by the display screen on eyes of a user when the electronic equipment is in the current environment or state in combination with the current glare value. For example, the glare threshold may be 10 or 11, etc. When the electronic equipment evaluates that the current glare value is smaller than the glare threshold value, the electronic equipment does not generate glare influencing eyes of the user in the process of determining that the user uses the electronic equipment. When the electronic equipment evaluates that the current glare value is larger than the glare threshold value, the electronic equipment determines that the generated glare value affects eyes of a user in the process of using the electronic equipment by the user.

Therefore, in the embodiment of the application, after the verification module determines the current glare value according to the parameter value corresponding to the glare parameter and the preset parameter, the verification module judges whether the current glare value is greater than the glare threshold value so as to determine whether the glare generated by the display screen of the electronic equipment causes discomfort to the user.

In the embodiment of the application, after the verification module determines the current glare value according to the parameter value corresponding to the glare parameter and the preset parameter, the verification module can judge the sizes of the current glare value and the glare threshold.

If the verification module determines that the current glare value is greater than the glare threshold, step 407 is performed, otherwise step 408 is performed.

In step 407, the verification module determines the target screen angle according to the distance between the electronic device and the user, the ambient light level, the current screen brightness, and the glare threshold.

In the embodiment of the application, when the verification module determines that the current glare value is greater than the glare threshold, the verification module determines the target screen angle according to one or more of the distance between the electronic device and the user, the ambient light level and the current screen brightness, and the glare threshold.

As one possible implementation, the verification module may determine the first solid angle based on the glare threshold, the current screen brightness, and the ambient light level. And then, the verification module determines the adjustment angle according to the first solid angle and the distance between the electronic equipment and the user, and then determines the sum of the adjustment angle and the fixed angle as a target screen angle. Wherein the fixed angle may be 90 °.

For example, the verification module may obtain the adjustment angle based on the distance between the electronic device and the user, the ambient light level, the current screen brightness, and the glare threshold value in combination with the above formula (1). Then, the verification module determines the target screen angle as the sum of the adjustment angle and the fixed angle. The adjustment angle refers to an angle to be adjusted by the electronic equipment based on the current screen angle.

For example, in the scenario shown in (a) of fig. 5, assuming that the distance between the electronic device and the user, which is sent by the detection module, is 0.35m, the environment light brightness of the electronic device is 95nit, the screen brightness is 177nit, the screen angle is 90 °, and after the screen light emitting area of the electronic device is 0.0428 square meters and the constant gas position index p=1 are obtained from the storage module, the current glare value UGR is calculated to be 11.66 according to the above formula (1). Assuming that the glare threshold is 10, the verification module determines that the current glare value is greater than the glare threshold, and the verification module may calculate, according to the above formula (1), that the glare value UGR is 10, the distance between the electronic device and the user is 0.35m, the ambient light level of the electronic device is 95nit, the screen brightness is 177nit, and when the screen light emitting area of the electronic device is 0.0428 square meters and p=1, the angle is adjusted21.8 °. At this time, the verification module may determine that the target screen angle of the electronic device is 90 ° +21.8 ° =111.8°, as shown in (b) of fig. 5.

In some embodiments, to avoid excessive screen brightness or ambient brightness resulting in a calculated open screen angle that affects the comfort of a user using the electronic device, the screen angle is typically about 105 ° (e.g., the second angle) to 110 ° (e.g., the first angle) when the electronic device is in use. Therefore, in the embodiment of the application, the electronic device can set. For example, the verification module calculates the corresponding adjustment angle when the glare UGR is 1021.8 DEG, the verification module can adjust the angleThe value was 20 °. At this time, the verification module may determine that the target screen angle of the electronic device is 110 °.

It can be understood that, even if the display screen does not generate glare affecting eyes of a user, the excessive screen angle affects comfort of the user for watching the display screen, so that in the embodiment of the application, an angle range for limiting a target screen angle can be preset, so that the electronic device adjusts the screen angle to the angle range, and the user can use the electronic device comfortably. For example, the angle may be 105 ° to 110 °, 110 ° to 120 °, and so on, which is not limited herein. For example, when the adjustment angle determined by the verification module is larger, resulting in the target screen angle being greater than 110 °, the verification module may determine that the target screen angle of the electronic device is 110 °, so that the user keeps comfortable feeling when watching the display screen.

In step 408, the verification module determines the target screen angle to be the second preset angle or the current screen angle.

The second preset angle may be a common angle of the electronic device used by the user and an angle of the display screen of the electronic device that does not generate glare, or the second preset angle may also be an optimal angle of the electronic device used and an angle of the display screen of the electronic device that does not generate glare. For example, the second preset angle may be 105 °, 108 °, 110 °, or the like.

In one possible case of the embodiment of the application, the verification module determines that the current glare value is not greater than the glare threshold value, and the verification module determines that the display screen of the electronic device in the current scene does not generate glare. In this case, the verification module may determine that the target screen angle of the electronic device is the second preset angle.

Under a scene, when the second preset angle is set by the electronic equipment to be the angle of the user commonly used angle of the electronic equipment and the display screen of the electronic equipment does not generate glare, the verification module of the electronic equipment determines that the display screen of the electronic equipment in the current scene does not generate glare, and the screen angle of the electronic equipment is not the second preset angle, the electronic equipment can control the screen angle to be adjusted to the second preset angle, so that the screen angle of the electronic equipment after the angle adjustment is the angle of the user commonly used angle, and the experience of the user using the electronic equipment is improved.

Under another scene, when the electronic equipment sets the second preset angle as the optimal use angle of the electronic equipment and the display screen of the electronic equipment does not generate glare, the verification module of the electronic equipment determines that the display screen of the electronic equipment in the current scene does not generate glare, and the screen angle of the electronic equipment is not the second preset angle, the electronic equipment can control the screen angle to be adjusted to the second preset angle, so that the screen angle of the electronic equipment after the angle adjustment is the optimal use angle of the electronic equipment for a user, and the comfort of the user in using the electronic equipment is improved.

In another possible case of the embodiment of the present application, the verification module determines that the current glare value is not greater than the glare threshold, and the verification module determines that the display screen of the electronic device in the current scene does not generate glare. In this case, the verification module may determine the current screen angle as the target screen angle. At this time, the control module does not need to adjust the screen angle of the electronic device.

Step 409, the verification module sends the target screen angle to the control module; correspondingly, the control module receives the target screen angle sent by the verification module.

In step 410, the control module controls the rotating motor to drive the connecting shaft to rotate so as to adjust the screen angle to the target screen angle.

In the embodiment of the application, after the control module receives the target screen angle sent by the verification module, the control module can control the rotating motor to drive the connecting shaft to rotate so as to adjust the screen angle to the target screen angle. Then, the control module can fix the screen angle at the target screen angle through the friction force of the rubber pads among the rotating shafts. For example, the control module may control the rotating motor to drive the connecting shaft to rotate at a certain rotational speed (e.g., the rotational speed may be 1 °/100 ms) to adjust the screen angle to the target screen angle.

TABLE 2

As shown in table 2, when the screen angle of the electronic device is 90 °, and the distance r between the electronic device and the user is unchanged, the background brightness and the screen brightness of the electronic device are obtained by the detection module of the electronic device under different ambient light intensities, the screen light emitting area pre-stored in the electronic device is 0.0428, the constant gas position index P is 1, and the verification module of the electronic device can calculate the current glare values UGR corresponding to different glare parameters according to the above formula (1). For example, the ambient light intensity collected by the detection module is 0, the screen brightness is 2.3, the distance r between the electronic device and the user is 0.35, the screen angle is 90 °, the screen light emitting area is 0.0428, and the constant Goos position index P is 1, and the verification module can calculate the current glare value UGR to be 13.32 according to the above formula (1). Since the preset glare threshold value is 10, the verification module determines that the current glare value is greater than the glare threshold value, and determines the adjustment angle according to the ambient light level, the screen brightness, the distance between the electronic device and the user and the glare threshold value32.89. The verification module can send the adjustment angle to the control moduleSuch that the control module controls the rotary motor to drive the connecting shaft to rotate 32.89 deg..

It should be explained that when the difference between the ambient light brightness and the screen brightness where the electronic device is located is small, the display screen of the electronic device does not generate glare. As shown in table 2, when the ambient light level where the electronic device is located is 3000lux, the glare value calculated by the electronic device is 9.46; when the brightness of the environment where the electronic equipment is positioned is 20000lux, the glare value calculated by the electronic equipment is 5.78. In this case, the electronic apparatus may not need to adjust the screen angle.

In the embodiment of the application, in the process of using the electronic equipment by a user, the electronic equipment can acquire the glare parameters in real time or periodically (such as 30 seconds, 1 minute and 2 minutes), and then calculate the current glare value according to the pre-stored screen light emitting area, the constant Goss position index and the glare parameters. When the electronic device determines that the current glare value is larger than the glare threshold value, the electronic device controls the screen angle to be adjusted to the target screen angle after determining the target screen angle according to one or more of the distance between the electronic device and the user, the ambient light level and the current screen brightness and the glare threshold value. Therefore, when the environment where the electronic equipment is located is changed, the electronic equipment can timely adjust the screen angle according to the real-time glare value, so that the generation of the glare phenomenon is avoided, the problem that the glare generated by the display screen of the electronic equipment affects eyes of a user is avoided, and the comfort of the user using the electronic equipment is provided.
