Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first", "second", and the like in the present invention are used for distinguishing different objects, not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The electronic equipment provided by the embodiment of the invention can be a mobile phone, a tablet personal computer, intelligent wearable equipment and the like.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for reducing a temperature rise of an electronic device, the method including:
s11: and acquiring the temperature of the display module or the adjacent area thereof.
The display module may specifically include a display panel and a backlight, and may further include a touch panel.
Optionally, in an embodiment, the temperature of the display module of the electronic device may be detected in real time when the electronic device is turned on; in another embodiment, the temperature of the display module of the electronic device can be detected in real time in a lighting state of the display module.
Optionally, the area adjacent to the display module may be a housing, a battery, and a CPU, and it can be understood that when the electronic device is in operation, the internal heat is generally transferred to the outside through the housing, so the temperature of the housing of the electronic device is relatively high; furthermore, the battery is used for supplying power to each part of the electronic equipment, and when the power consumption is large, the temperature of the battery is often high; in addition, the CPU is used for data processing, and when multiple applications of the electronic equipment run simultaneously, the load of the CPU is large, and the temperature is high. Therefore, the temperature detection of the shell, the battery and the CPU of the electronic equipment has certain referential property.
In addition, the temperature of a plurality of positions of the electronic equipment can be detected, and an average value can be calculated. Taking the display module as an example, one or more temperature sensors may be disposed at the side of the display screen, the back of the backlight, or other positions to detect the temperature of the display module. Alternatively, the temperature sensor may be a thermistor.
S12: and when the temperature of the display module or the adjacent area is greater than the set temperature threshold value, acquiring the gray-scale value of the current display picture of the display module.
The set temperature threshold may be a default value in a factory setting of the electronic device, or may be determined according to a setting of a user, which is not limited herein. In addition, the set temperature threshold may include a plurality of temperature thresholds, for example, different temperature thresholds may be set for the display module or its neighboring area, and one temperature threshold may be set for the average temperature value of a plurality of components.
The gray scale is a change in luminance between the brightest and darkest, and is divided into a plurality of parts. So as to control the screen brightness corresponding to the signal input. Each digital image is composed of a plurality of dots, also called pixels (pixels), each of which can usually represent a plurality of different colors, and in most display modules, it is composed of three sub-pixels of red, green and blue (RGB). Each sub-pixel, the light source behind it, may exhibit a different brightness level. And the gray levels represent gradation levels of different brightness from the darkest to the brightest. The more the intermediate levels are, the more exquisite the picture effect can be presented. Taking 8bit panel as an example, the image can represent 2 to the power of 8, which is equal to 256 luminance levels, and we refer to it as 256 gray levels. Each pixel on the LCD screen is composed of red, green and blue with different brightness levels to form different color dots. That is, the color change of each dot on the screen is actually caused by the gray scale change of the three RGB sub-pixels constituting the dot.
In this embodiment, the current display frame of the display module is a frame currently displayed by the display module, and the pixel value of the current display frame may be an average value of gray-scale values of all the pixel points.
S13: and when the gray-scale value of the current display picture meets the set condition, reducing the brightness of the current display picture.
Specifically, in an embodiment, S13 may specifically be: and when the gray scale value of the current display picture is larger than the set gray scale threshold value, reducing the brightness of the current display picture.
Specifically, the dimming of the brightness of the current display frame may be dimming of the backlight of the display screen, so that the power consumption of the backlight is reduced, and further, the heat generation of the backlight is reduced.
It is understood that 256 gray scale values (0-255) are taken as an example, wherein 0 gray scale is completely black and 225 gray scale is completely white. Therefore, when the gray scale value is larger than the set gray scale threshold value, the current display picture is white, the display picture is bright at the moment and is the moment when the display module consumes the most power, and therefore the brightness of the display module is reduced at the moment, the heating of the display module is better reduced, and the temperature rise of the electronic equipment is restrained.
Further, when the gray scale value of the display frame is higher (i.e. the frame is whiter and brighter), it means that there are more blank areas in the display frame. For example, the display screen is a chat interface, a web browsing interface, a novel reading interface, and the like, and in the application scene, the brightness of the display screen is reduced, so that the power consumption is reduced, the temperature rise is reduced, and the protection of the eyes of the user is facilitated.
The method for reducing the temperature rise of the electronic equipment provided by the embodiment comprises the following steps: acquiring the temperature of the display module or the adjacent area thereof; when the temperature of the display module or the adjacent area is larger than a set temperature threshold value, acquiring a gray scale value of a current display picture of the display module; and when the gray-scale value of the current display picture meets the set condition, reducing the brightness of the current display picture. Through the mode, the power consumption of the display module can be reduced, and the temperature rise of the display module and the whole electronic equipment is further reduced.
Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of a method for reducing a temperature rise of an electronic device, the method including:
s21: and acquiring the temperature of the display module or the adjacent area thereof.
S22: the current display screen is divided into a plurality of display areas.
Optionally, in an embodiment, the display area may be divided into a plurality of rectangular areas on average. For example, in the vertical screen state, the display area is divided into an upper display area and a lower display area; or in the horizontal screen state, the display area is divided into four display areas, namely, upper left display area, upper right display area, lower left display area and lower right display area.
Optionally, in another embodiment, the display area may be divided according to the displayed content. For example, when taking a picture, the display screen can be divided into a picture preview area and other operation areas; when the chat interface is used, the chat interface can be divided into a chat content display area and an input method display area; in the video call, the video call can be divided into a video area and other operation areas.
S23: when the temperature of the display module or the adjacent area is larger than the set temperature threshold value, the gray-scale values of the plurality of display areas are respectively obtained.
Alternatively, the average of the gray-scale values of all the pixels of each display area may be calculated separately.
S24: and reducing the brightness of the display area with the gray-scale value meeting the set conditions.
Optionally, in S24, the brightness of the display area with the grayscale value greater than the set grayscale threshold may be turned down.
As can be appreciated, with the development of large-sized panels, the display screen of the existing electronic device is often larger, in the intelligent electronic device, one display interface can often display more contents, and different contents are often different in color tone.
Taking a microblog browsing interface as an example, when a microblog is browsed, more pictures are often seen, wherein the tone of the pictures is often different from that of a background interface. At this time, the system can automatically partition the display screen according to the displayed content, namely, the picture is divided into one area, and the background is divided into one area. Different adjustments are then made according to the gray scale values of the different regions.
Referring to fig. 3, fig. 3 is a schematic flow chart of another embodiment of a method for reducing a temperature rise of an electronic device, the method including:
s31: and acquiring the temperature of the display module or the adjacent area thereof.
S32: and when the temperature of the display module or the adjacent area is greater than the set temperature threshold value, acquiring the gray-scale value of the current display picture of the display module.
S33: and acquiring an effective display area in the current display picture.
S34: and when the gray-scale value of the current display picture meets the set condition, reducing the brightness of the display area except the effective display area in the current display picture.
The effective display area is a video playing area.
It can be understood that the content generally played in the video playing area is content with a higher requirement on display quality, such as a television show, a movie, and the like, and if the brightness of the video playing area is reduced, the experience of the user is affected, so in this embodiment, the brightness of the video playing interface is not adjusted.
In addition, alternatively, in the above embodiment, the order of steps of S32 and S33 may be reversed, and then in S32, the gray scale values of the display screens of the other regions of the display module except for the video playing region may be simply acquired.
It is understood that the set gray level threshold may be different in different embodiments. For example, in the third embodiment, since the importance of other display interfaces is low during video playing, and the user does not frequently use other areas when watching video, in this embodiment, the gray level threshold may be set to a small number, in other words, even if the brightness of these areas is dark, the brightness of these areas may be further reduced.
In addition, in the above embodiments, the degree of dimming the display module may be determined according to the temperature. For example, when the temperature is greater than the first preset value, the luminance is reduced by 10%, and when the temperature is greater than the second preset value (the second preset value is greater than the first preset value), the luminance is reduced by 20%.
The present invention also provides a computer-readable storage medium on which a schematic structural diagram of an embodiment of a computer program is stored, the computer-readable storage medium being used for storing the computer program, and the computer program being executed by a processor to implement the method provided in the above embodiment. It is understood that the method executed by the computer program stored in the readable storage medium in this embodiment is similar to the method provided in the foregoing embodiments, and the principle and steps thereof are the same, and are not described herein again.
