The embodiment of the disclosure provides an electronic device, which comprises a display screen, a first temperature sensor, a second temperature sensor and a light sensor. The display screen is used for displaying operation information, image information and the like. The first temperature sensor is used for detecting the temperature of the display screen. The second temperature sensor is used for detecting the ambient temperature of the display screen. The light sensor is used to detect the intensity of ambient light.
In combination with the above electronic device, an embodiment of the present disclosure provides a method for controlling backlight of a display screen. As shown in fig. 1, the method includes:
S101, the electronic equipment acquires a first temperature difference between a first temperature of the display screen and a first environment temperature.
The first temperature is the detected current temperature of the display screen, the first ambient temperature is the temperature of the environment where the display screen corresponding to the current temperature of the display screen is located, and the first temperature difference is obtained by subtracting the first ambient temperature from the first temperature of the display screen.
S102, the electronic equipment determines a first temperature difference threshold according to the first environment temperature.
S103, the electronic equipment adjusts the screen brightness of the display screen according to the first temperature difference and the first temperature difference threshold value.
In the embodiment of the disclosure, the heat dissipation effect of the display screen is directly affected by the environmental temperature, and the heat dissipation of the display screen is slower as the environmental temperature is higher. In the same working state, the higher the ambient temperature is, the faster the temperature of the display screen rises, and the smaller the temperature difference threshold needs to be set. The temperature change condition of the display screen can be judged according to the temperature difference between the temperature of the display screen and the current ambient temperature, and different ambient temperatures set different temperature difference thresholds. Therefore, the inaccuracy of single working temperature threshold judgment is avoided by adjusting the screen brightness of the display screen through the first temperature difference and the first temperature difference threshold, and the display screen is not unstable in operation due to the fact that the temperature of the display screen is raised too high due to different environment temperatures. Thus, the continuous operation stability of the display screen is improved. Meanwhile, the temperature of the display screen is kept at a lower temperature, so that the heat dissipation of the electronic equipment system is facilitated, and the running performance of the system can be improved.
Optionally, the electronic device determines a first temperature difference threshold according to the first ambient temperature, including: and the electronic equipment determines a first temperature difference threshold corresponding to the first ambient temperature according to the mapping relation between the ambient temperature and the temperature difference threshold. Wherein the ambient temperature is inversely related to the temperature difference threshold. The mapping relationship between the ambient temperature and the temperature difference threshold is a one-to-one correspondence relationship between the ambient temperature and the temperature difference threshold stored in the electronic device. For example T Ring(s) The corresponding temperature difference threshold value is 20 ℃ and less than or equal to 10 ℃ and less than T is 10 DEG C Ring(s) The corresponding temperature difference threshold value is 17 ℃ and less than or equal to 20 ℃ and less than T at 20 DEG C Ring(s) The corresponding temperature difference threshold value is 15 ℃ and T is less than or equal to 30 DEG C Ring(s) A corresponding temperature difference threshold of > 30 ℃ of 13 ℃, wherein T Ring(s) Is ambient temperature. The specific corresponding relation between the ambient temperature and the temperature difference threshold value can be determined according to the relation between the ambient temperature and the temperature change condition, the running stability condition and the like of different display screens in the actual use process. For example, the temperature of the display screen can be increased continuously by setting the ambient temperature, operating and setting the electronic device at different ambient temperatures, and recording the operation and running conditions of the display screen. Under the condition that the operation and running conditions of the display screen are not smooth or abnormal, the temperature of the display screen is recorded, and a difference value between the temperature of the display screen and the ambient temperature is calculated, wherein the difference value can be used as a temperature difference threshold value under the ambient temperature. Of course, the difference can be reduced by a certain extent as the temperature difference threshold value at the ambient temperature, so that the temperature difference threshold value can be avoided The operation stability of the display screen is greatly affected in the process of adjusting the brightness of the display screen. According to the actual conditions, the corresponding relation can be determined for the environmental temperature dividing sections. Therefore, the optimal temperature difference threshold value of the display screen can be determined according to the environment temperature of the display screen, and the screen brightness of the display screen is further adjusted according to the first temperature difference and the first temperature difference threshold value. Therefore, the phenomenon that the display screen is unstable to operate due to the fact that the temperature of the display screen is too high in the operation process of the display screen is reduced, and the stability of continuous operation of the display screen is improved.
Optionally, the electronic device adjusts screen brightness of the display screen according to the first temperature difference and the first temperature difference threshold, including: and under the condition that the first temperature difference is larger than a first temperature difference threshold value, the electronic equipment adjusts the screen brightness of the display screen according to the ambient light intensity. And maintaining the current screen brightness under the condition that the first temperature difference is smaller than or equal to a first temperature difference threshold value. The ambient light intensity at which the electronic device is located can be detected by the light sensor. Thus, the screen brightness of the display screen is adjusted according to the ambient light intensity, so that the screen brightness of the display screen can be matched with the ambient light intensity. Therefore, the user can watch more comfortably, and the user experience is better.
Optionally, the electronic device adjusts screen brightness of the display screen according to the first temperature difference and the first temperature difference threshold, including: and under the condition that the first temperature difference is larger than a first temperature difference threshold value and the duration time is longer than or equal to the preset duration time, the electronic equipment adjusts the screen brightness of the display screen according to the ambient light intensity. And maintaining the current screen brightness under the condition that the first temperature difference is smaller than or equal to a first temperature difference threshold value. In this way, misjudgment caused by accidental detection errors can be avoided by judging the duration. Thus, the accuracy of judgment can be improved.
Optionally, the electronic device adjusts the screen brightness of the display screen according to the ambient light intensity, including: the electronic device obtains a current ambient light intensity. And the electronic equipment determines the first screen brightness corresponding to the current ambient light intensity according to the mapping relation between the ambient light intensity and the screen brightness. The electronic equipment adjusts the screen brightness of the display screen according to the first screen brightness. The mapping relation between the ambient light intensity and the screen brightness is one-to-one correspondence relation between the ambient light intensity and the screen brightness stored in the electronic equipment. At different ambient light intensities, different screen brightness is different for user viewing comfort. For example, different ranges of ambient light intensity may be set to correspond to different screen brightnesses. Thus, the screen brightness of the display screen can be matched with the ambient light intensity more by adjusting the corresponding different screen brightness according to different ambient light intensities. Therefore, the user can watch more comfortably, and the user experience is better.
As shown in conjunction with fig. 2, an embodiment of the present disclosure provides another method for display screen backlight control, including:
s201, the electronic device obtains a first temperature difference between a first temperature of the display screen and a first ambient temperature.
S202, the electronic device determines a first temperature difference threshold according to the first ambient temperature.
And S203, under the condition that the first temperature difference is larger than a first temperature difference threshold value, the electronic equipment acquires the current ambient light intensity.
S204, the electronic equipment determines the first screen brightness corresponding to the current ambient light intensity according to the mapping relation between the ambient light intensity and the screen brightness.
S205, the electronic equipment adjusts the screen brightness of the display screen according to the first screen brightness.
In the embodiment of the disclosure, different screen brightness is different for comfort of viewing by a user under different ambient light intensities. For example, different ranges of ambient light intensity may be set to correspond to different screen brightnesses. Thus, the screen brightness of the display screen can be matched with the ambient light intensity more by adjusting the corresponding different screen brightness according to different ambient light intensities. Therefore, the user can watch more comfortably, and the user experience is better.
Optionally, the electronic device adjusts the screen brightness of the display screen according to the first screen brightness, including: the electronic device obtains a first current screen brightness of the display screen. And under the condition that the first screen brightness is smaller than the first current screen brightness, the electronic equipment adjusts the screen brightness of the display screen to the first screen brightness. And under the condition that the first screen brightness is greater than or equal to the first current screen brightness, the electronic equipment reduces the screen brightness of the display screen by a preset brightness threshold value. Thus, since the screen brightness of the display screen has a large influence on the temperature of the display screen, the temperature of the display screen can be lowered by lowering the screen brightness. Therefore, the phenomenon that the display screen is unstable in operation due to the fact that the temperature of the display screen is too high in the operation process of the display screen is reduced, and the stability of continuous operation of the display screen is improved. For example, the display has a screen brightness ranging from 0 to 100, a current screen brightness of 80, an ambient light intensity of 100lx, and a screen brightness corresponding to 60 according to a mapping relationship between the ambient light intensity and the screen brightness, the 60 is determined as the first screen brightness, and the screen brightness of the display screen is adjusted to 60.
Alternatively, the preset brightness threshold may be determined according to a correspondence between a degree to which the first temperature difference is greater than the first temperature difference threshold and the preset brightness threshold, where the greater the degree to which the first temperature difference is greater than the first temperature difference threshold, the greater the preset brightness threshold. The preset brightness threshold value can also be determined according to the corresponding relation between the temperature rising rate of the display screen and the preset brightness threshold value, and the faster the temperature rising rate of the display screen is, the larger the preset brightness threshold value is. In this way, different preset brightness thresholds are determined according to the actual value of the temperature of the display screen, so that the screen brightness of the display screen can be kept at proper brightness. Therefore, the phenomenon that the use experience of a user is influenced due to the fact that the screen brightness of the display screen is too low is avoided.
Optionally, after the electronic device adjusts the screen brightness of the display screen, the method further includes: the electronic device obtains a plurality of second temperature differences between a second temperature of the display screen and a second ambient temperature. The electronic equipment respectively determines a second temperature difference threshold value corresponding to each second environment temperature. The electronic equipment obtains the difference change condition of the second temperature difference and the second temperature difference threshold value. And the electronic equipment determines the brightness of the second screen according to the change condition of the difference value. The electronic device adjusts the screen brightness of the display screen to be the second screen brightness. The second temperature is the current temperature of the display screen detected at intervals, the second ambient temperature is the temperature of the environment where the display screen corresponding to the current temperature of the display screen is located, and the difference value between the second temperature difference and the second temperature difference threshold value is the difference value of the second temperature difference minus the second temperature difference threshold value. After the screen brightness of the display screen is adjusted, a plurality of corresponding second temperature differences can be obtained by detecting the second temperature of the display screen and the second ambient temperature for a plurality of times, and the second temperature difference threshold corresponding to each ambient temperature can be determined by the mapping relation between the ambient temperature and the temperature difference threshold. Thus, the difference change condition of the second temperature difference and the second temperature difference threshold value can be obtained by calculating the difference value of each second temperature difference and the corresponding second temperature difference threshold value. Thus, the actual effect after the screen brightness adjustment can be determined according to the variation of the difference value. Furthermore, the screen brightness of the display screen can be further adjusted according to the actual effect, and the continuous rising of the temperature of the display screen is avoided.
As shown in conjunction with fig. 3, an embodiment of the present disclosure provides another method for display screen backlight control, including:
s301, the electronic device obtains a first temperature difference between a first temperature of the display screen and a first ambient temperature.
S302, the electronic equipment determines a first temperature difference threshold according to the first environment temperature.
S303, under the condition that the first temperature difference is larger than a first temperature difference threshold value, the electronic equipment acquires the current ambient light intensity.
S304, the electronic equipment determines the first screen brightness corresponding to the current ambient light intensity according to the mapping relation between the ambient light intensity and the screen brightness.
S305, the electronic equipment adjusts the screen brightness of the display screen according to the first screen brightness.
S306, the electronic device obtains a plurality of second temperature differences between the second temperature of the display screen and the second ambient temperature.
S307, the electronic device determines a second temperature difference threshold corresponding to each second ambient temperature.
S308, the electronic device obtains the difference value change condition of the second temperature difference and the second temperature difference threshold value.
S309, the electronic equipment determines the brightness of the second screen according to the change condition of the difference value.
S310, the electronic device adjusts the screen brightness of the display screen to be the second screen brightness.
In the embodiment of the disclosure, after the screen brightness of the display screen is adjusted, a plurality of corresponding second temperature differences can be obtained by detecting the temperature of the display screen and the ambient temperature for a plurality of times, and the second temperature difference threshold corresponding to each ambient temperature can be determined by the mapping relation between the ambient temperature and the temperature difference threshold. Thus, the difference change condition of the second temperature difference and the second temperature difference threshold value can be obtained by calculating the difference value of each second temperature difference and the corresponding second temperature difference threshold value. Thus, the actual effect after the screen brightness adjustment can be determined according to the variation of the difference value. Furthermore, the screen brightness of the display screen can be further adjusted according to the actual effect, and the continuous rising of the temperature of the display screen is avoided.
Optionally, the electronic device determines the second screen brightness according to the difference change condition, including: and under the condition that the difference is positive and the rising trend is generated, the electronic equipment determines the difference change rate of the second temperature difference and the second temperature difference threshold value, the current environment temperature and the second current screen brightness of the display screen. And the electronic equipment determines the second screen brightness according to the difference change rate, the current environment temperature and the second current screen brightness. The rate of change of the difference between the second temperature difference and the second temperature difference threshold may be calculated by dividing the value of the change in the difference by time. The electronic device determining a second screen brightness according to the difference change rate, the current ambient temperature and the second current screen brightness, including: and the electronic equipment determines the second screen brightness according to the mapping relation among the difference change rate, the ambient temperature and the screen brightness. Wherein the rate of change of the difference is inversely related to the screen brightness. And if the difference value is smaller than or equal to zero or the difference value is in a descending trend, maintaining the second current screen brightness. The mapping relationship of the difference change rate, the ambient temperature and the screen brightness is one-to-one correspondence of the difference change rate, the ambient temperature and the screen brightness stored in the electronic device. The rate of change of the difference may be calculated by the change of the difference over a preset period of time. Through a preset corresponding relation, under the condition that the ambient temperature and the change rate of the difference value are known, the screen brightness can be determined, so that the temperature of the display screen can not continuously rise. Due to the use of air conditioning and other equipment or the change of weather, the ambient temperature may change at any time, and thus the temperature difference and the temperature difference threshold corresponding to the ambient temperature may also change. And judging the difference value change condition of the second temperature difference and the second temperature difference threshold value by continuously detecting the temperature difference between the temperature of the display screen and the current environment temperature. If the difference is positive and the temperature is rising, the temperature of the display screen is too high, and the brightness of the screen still causes the continuous rising of the temperature of the display screen. Thus, a proper screen brightness can be determined according to the corresponding relation among the difference change rate, the ambient temperature and the screen brightness. Therefore, the continuous temperature rise of the display screen is avoided, and the running stability of the display screen is ensured.
Optionally, the method further comprises: and when the first temperature difference is larger than the first temperature difference threshold value and no user operation is needed, the electronic equipment reduces the standby waiting time of the display screen. And under the condition that the first temperature difference is larger than a first temperature difference threshold value and the user operation is performed, the electronic equipment carries out information prompt so as to adjust the screen brightness of the display screen according to a screen brightness instruction sent by the user based on the information prompt. The information prompt can enable the user to know that the temperature of the current display screen is too high, and prompt the user to adjust the ambient light intensity to be comfortable to watch according to the adjusted screen brightness. The information prompt comprises one or more of voice prompt, alarm prompt or related text prompt display. Therefore, when the first temperature difference is larger than the first temperature difference threshold value and no user operation is needed, the standby waiting time of the electronic equipment is reduced, the display screen of the electronic equipment can be put into standby as soon as possible, and the temperature of the display screen is reduced. When the first temperature difference is larger than the first temperature difference threshold value and the user operates, the electronic equipment prompts information for the user, and the user adjusts the ambient light intensity to be comfortable to watch according to the adjusted screen brightness, so that the operation and the watching comfort of the user are better under the condition that the stable operation of the display screen can be ensured. Therefore, the operation experience of the user is improved.
As shown in conjunction with fig. 4, an embodiment of the present disclosure provides another method for display screen backlight control, including:

And S405, under the condition that the first temperature difference is larger than a first temperature difference threshold value and the user operates, the electronic equipment carries out information prompt so as to adjust the screen brightness of the display screen according to a screen brightness instruction sent by the user based on the information prompt.
In the embodiment of the disclosure, when the first temperature difference is greater than the first temperature difference threshold and no user operation is needed, the standby waiting time of the electronic equipment is reduced, so that the display screen of the electronic equipment can enter standby as soon as possible, and the temperature of the display screen is reduced. When the first temperature difference is larger than the first temperature difference threshold value and the user operates, the electronic equipment prompts information for the user, and the user adjusts the ambient light intensity to be comfortable to watch according to the adjusted screen brightness, so that the operation and the watching comfort of the user are better under the condition that the stable operation of the display screen can be ensured. Therefore, the operation experience of the user is improved.
Optionally, the electronic device further comprises a heat dissipation fan. And when the difference value between the first temperature difference and the first temperature difference threshold is greater than or equal to the first difference threshold, the electronic equipment starts the cooling fan. The first difference threshold may be set according to the actual situation. Therefore, the display screen and the electronic equipment system can be better cooled. Therefore, the stable operation of the display screen and the electronic equipment system is ensured.
Optionally, the method further comprises: in the event that the first temperature difference is greater than the first temperature difference threshold, the electronic device shuts down unnecessary applications. Therefore, the CPU occupation rate can be reduced, and the influence of the heat of the system on the display screen is reduced. Thus, system power consumption is reduced and the temperature of the display screen is reduced. Furthermore, the stable operation of the display screen and the electronic equipment system can be ensured.
In the actual use process of the method, for example, in the case that the electronic device is an intelligent control panel, the operation mode of the intelligent control panel may set a normal operation mode and an energy-saving operation mode, and the brightness mode of the intelligent control panel may include a manual mode and an intelligent mode. In the manual mode, the brightness of the panel screen can be manually adjusted, and the brightness display percentage is adjusted within the range of 0-100. Wherein luminance 0 is the lowest luminance and luminance 100 is the highest luminance. Each brightness level corresponds to a different PWM duty cycle, and the system adjusts the brightness of the screen by adjusting the size of the PWM duty cycle. In the intelligent mode, the panel intelligently adjusts the screen brightness according to the collected ambient light intensity, so that the screen brightness is automatically adapted to the environment and adjusted to the most comfortable brightness of human eyes. In case of manual mode or intelligent mode operation, the above-described method for display screen backlight control is performed. When the user is detected to be at home, the system enters a normal operation mode, and meanwhile, the brightness mode operates according to the system state and the user setting value, and the method for controlling the backlight of the display screen is executed. When the user leaves home, the system enters an energy-saving operation mode, the panel sets the standby waiting time to be the shortest, and sets the screen brightness to be the lowest. Whether a person in the user's home can bind the user's home personnel through an application program or pass through an intelligent sensor in the home is judged, and the intelligent sensor comprises a human body sensor, an intelligent door lock and the like.
Another method for controlling backlight of a display screen during actual operation of an electronic device is shown in fig. 5, and includes:
s501, acquiring the temperature of a display screen and the current environment temperature.
S502, calculating a first temperature difference between the temperature of the display screen and the current environment temperature. For example, the temperature of the display screen is 50 ℃, the current ambient temperature is 22 ℃, and the first temperature difference is 28 ℃.
S503, determining a first temperature difference threshold corresponding to the current ambient temperature according to the mapping relation between the ambient temperature and the temperature difference threshold. For example, the current ambient temperature is 22 ℃, and the first temperature difference threshold corresponding to the ambient temperature is 20 ℃.
S504, acquiring the current ambient light intensity under the condition that the first temperature difference is larger than a first temperature difference threshold value. For example, if the temperature difference is 28 ℃, the temperature difference threshold corresponding to the current ambient temperature is 20 ℃, and the obtained current ambient light intensity is 100lx.
S505, determining the first screen brightness corresponding to the current ambient light intensity according to the mapping relation between the ambient light intensity and the screen brightness. For example, the current ambient light intensity is 100lx, and the corresponding screen brightness is 60.
S506, adjusting the screen brightness of the display screen to be the first screen brightness under the condition that the first screen brightness is smaller than the first current screen brightness. For example, if the first screen brightness is 60 and the first current screen brightness is 80, the screen brightness of the display screen is adjusted to 60.
S507, reducing the screen brightness of the display screen by a preset brightness threshold value under the condition that the first screen brightness is larger than or equal to the first current screen brightness. For example, if the first screen brightness is 60, the first current screen brightness is 50, and the preset brightness threshold is 10, the screen brightness of the display screen is adjusted to 40.
S508, a plurality of second temperature differences between the second temperature of the display screen and the second ambient temperature are obtained. For example, the temperature of the display screen and the ambient temperature are acquired every 30s and the second temperature difference is calculated.
S509, determining a second temperature difference threshold corresponding to each second ambient temperature. For example, the temperature and the ambient temperature of the display screen are obtained for 4 times within 2 minutes, and the second temperature difference threshold value of each time can be determined according to the mapping relation between the ambient temperature and the temperature difference threshold value.
S510, obtaining the difference value change condition of the second temperature difference and the second temperature difference threshold value. For example, the difference between the second temperature difference and the second temperature difference threshold value for 4 times is 2 ℃, 2.3 ℃, 2.5 ℃, 2.8 ℃ from front to back, respectively, and the change of the difference can be judged from the difference.
S511, determining the change rate of the difference value between the second temperature difference and the second temperature difference threshold, the current ambient temperature and the second current screen brightness of the display screen under the condition that the difference value is positive and has an ascending trend.
S512, determining the second screen brightness according to the mapping relation of the difference change rate, the ambient temperature and the screen brightness.
S513, adjusting the screen brightness of the display screen to the second screen brightness.
