Detailed Description
Hereinafter, a display method and an electronic apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
According to an aspect of the embodiments of the present invention, there is provided a display method applied to an electronic device having a display screen, the method including: obtaining a first brightness value of the display screen; obtaining a second brightness value of the display screen, wherein the second brightness value is lower than the first brightness value and greater than zero; detecting whether the state of the electronic equipment meets a preset condition; and automatically adjusting the brightness value of the display screen so that the brightness value continuously changes between the first brightness value and the second brightness value when the state of the electronic device meets a predetermined condition.
Fig. 1 is a schematic flowchart illustrating a display method according to an embodiment of the present invention. As shown in fig. 1, a display method according to an embodiment of the present invention is applied to an electronic device having a display screen, and the method includes: s1, obtaining a first brightness value of the display screen; s2, obtaining a second brightness value of the display screen, wherein the second brightness value is lower than the first brightness value and is greater than zero; s3, detecting whether the state of the electronic equipment meets a preset condition; and S4, automatically adjusting the brightness value of the display screen under the condition that the state of the electronic equipment meets the preset condition, so that the brightness value continuously changes between the first brightness value and the second brightness value.
With the above display method, when the state of the electronic device satisfies a predetermined condition, the luminance value of the display screen of the electronic device may be continuously adjusted between a first luminance value and a second luminance value lower than the first luminance value, so that the luminance value of the display screen of the electronic device is not always maintained at the larger first luminance value but continuously varies within a certain range below the first luminance value. Thus, as the brightness value of the display screen of the electronic device is reduced, the power consumption generated by the backlight unit is correspondingly reduced, thereby realizing the reduction of the power consumption of the whole electronic device.
And because the second brightness value is greater than zero, when the brightness value of the display screen of the electronic device changes between the first brightness value and the second brightness value, the display screen of the electronic device is not in a black screen state, so that the display screen of the electronic device does not flicker/refresh.
In the embodiment of the invention, the brightness of the display screen can be automatically adjusted by detecting the state of the electronic equipment, so that on one hand, the complexity of manual operation of a user is saved, and on the other hand, the adjustment of the brightness of the display screen can be optimized according to the state of the electronic equipment, thereby further enhancing the user experience. Of course, those skilled in the art will understand that the above-mentioned detecting whether the state of the electronic device satisfies the predetermined condition and automatically and continuously adjusting the brightness value of the display screen of the electronic device if the state of the electronic device satisfies the predetermined condition does not mean a specific condition or conditions, and the display method according to the embodiment of the present invention may also be configured to automatically adjust the brightness value of the display screen in any case regardless of the state of the electronic device, and the embodiment of the present invention is not intended to be limited thereto.
In addition, in the display method according to the embodiment of the invention, the brightness value of the display screen of the electronic device may be continuously changed between the first brightness value and the second brightness value, rather than only being directly changed from the first brightness value to the second brightness value, so that the brightness value of the display screen is adjusted such that the brightness value of the display screen is not always maintained at the higher first brightness value, thereby reducing the energy consumption of the electronic device, and at the same time, the brightness value of the display screen of the electronic device is continuously changed, so as not to generate a feeling that the brightness change of the display screen is abrupt for a user due to the fact that the brightness value of the display screen is directly changed to the second brightness value and is maintained at the second brightness value thereafter.
In the display method according to the embodiment of the invention, the continuous variation of the brightness value of the display screen of the electronic device between the first brightness value and the second brightness value includes at least two times of variation, and in addition, the continuous variation may also include random variation or regular variation within the range of the first brightness value and the second brightness value. A specific example in which the luminance value of the display screen of the electronic device continuously changes between the first luminance value and the second luminance value will be described in detail below.
In the display method, the step of obtaining the second brightness value of the display screen specifically includes: obtaining a calculation strategy; obtaining a third brightness value according to the first brightness value and the calculation strategy; taking the third brightness value as the second brightness value.
As described above, in the display method according to the embodiment of the present invention, the second luminance value is smaller than the first luminance value and larger than zero, and therefore, the second luminance value can be arbitrarily set in the range from zero to the first luminance value. However, since the change in the luminance value of the display screen is easily perceived by the viewer, it is preferable to set the second luminance value to have a certain relationship with the first luminance value, so as to further optimize the adjustment of the luminance value of the display screen of the electronic device. For example, in the embodiment of the present invention, the calculation strategy may be that the second luminance value is a certain percentage of the first luminance value, so that the second luminance value has a certain proportional relationship with the first luminance value. For example, if the above calculation strategy is obtained to be 60% of the first luminance value, the second luminance value will be 60% of the first luminance value. Of course, one skilled in the art will appreciate that the computational policy may be any computational policy and embodiments of the present invention are not intended to be limiting in any way.
In the display method, the step of obtaining the first brightness value of the display screen specifically includes: obtaining a current brightness value of the display screen; and taking the current brightness value as the first brightness value.
In the display method according to the embodiment of the present invention, the first luminance value and the second luminance value may be arbitrarily set luminance values, and it is only necessary to satisfy a condition that the second luminance value is smaller than the first luminance value and larger than zero. However, as described above, since the luminance value of the display screen is easily perceived by the user, it is preferable to set the first luminance value to the current luminance value of the screen, that is, the luminance value present on the display screen currently being viewed by the user. Therefore, when the brightness value of the display screen of the electronic equipment continuously changes between the first brightness value and the second brightness value, the abrupt feeling of the change of the brightness value can be further reduced, and the user experience is enhanced.
In the display method, the step of automatically adjusting the brightness value of the display screen specifically includes: obtaining at least one transition luminance value between the first luminance value and the second luminance value in dependence on the first luminance value and the second luminance value; and adjusting the brightness value of the display screen in the order of the first brightness value, the transition brightness value and the second brightness value.
In the above, it has been mentioned that there may be various examples of the continuous change of the brightness value of the display screen of the electronic device between the first brightness value and the second brightness value, wherein the brightness value of the display screen of the electronic device may be set to gradually change between the first brightness value and the second brightness value, that is, at least one transition brightness value may be set between the first brightness value and the second brightness value, and the brightness value of the display screen of the electronic device may be changed from the first brightness value to the second brightness value by the at least one transition brightness value, so that the user may not easily perceive the change of the brightness value of the display screen of the electronic device, thereby enhancing the user experience.
Here, as can be understood by those skilled in the art, the larger the number of transition luminance values set between the first luminance value and the second luminance value, the more gradual the change of the luminance value between the first luminance value and the second luminance value will appear, and the better the user experience, but at the same time, too many transition luminance values may cause a burden of luminance value adjustment of a display screen of the electronic device, thereby reducing the overall performance of the electronic device.
In the above display method, after the step of adjusting the brightness value of the display screen in the order of the first brightness value, the transition brightness value, and the second brightness value, the method further includes: and adjusting the brightness value of the display screen according to the sequence of the second brightness value, the transition brightness value and the first brightness value.
It has been mentioned in the following that the display method according to the embodiment of the present invention may enhance the user experience while reducing the power consumption of the electronic device, compared to the adjustment of the display screen luminance value directly decreasing from the first luminance value to the second luminance value and then maintaining at the second luminance value all the time. In the embodiment of the present invention, it is further preferable that the luminance value of the display screen of the electronic device is caused to change in a "sine wave" manner between the first luminance value and the second luminance value, that is, after the luminance value of the display screen of the electronic device is gradually changed from the first luminance value to the second luminance value, the luminance value is gradually changed from the second luminance value to the first luminance value. In this way, since the continuous change of the brightness value of the display screen of the electronic device between the first brightness value and the second brightness value includes both the process from light to dark and the process from dark to light, and is not always maintained in a relatively dark condition, it is possible to avoid a situation that the brightness value of the display screen of the electronic device is too low due to the change of the brightness of the surrounding environment when the surrounding environment of the electronic device changes, for example, when the user reaches the outdoor environment full of sunlight from the indoor environment, thereby further enhancing the user experience.
In the above display method, the step of obtaining the at least one transition luminance value specifically includes: obtaining the at least one transition luminance value in the following manner: a difference between a maximum one of the transition luminance values and the first luminance value is equal to a difference between a minimum one of the transition luminance values and the second luminance value; and a difference between any two consecutive transition luminance values in the transition luminance values is equal and equal to a difference between a maximum transition luminance value in the transition luminance values and the first luminance value and a difference between a minimum transition luminance value in the transition luminance values and the second luminance value.
In the above display method, the step of adjusting the brightness value of the display screen according to the order of the first brightness value, the transition brightness value, and the second brightness value specifically includes: adjusting the brightness of the display screen in the following manner: an adjustment time from the first luminance value to a maximum one of the transition luminance values is equal to a luminance time from a minimum one of the transition luminance values to the second luminance value; and the adjustment time between any two consecutive transition luminance values of the transition luminance values is equal and equal to the adjustment time from the first luminance value to the largest transition luminance value of the transition luminance values and the luminance time from the smallest transition luminance value of the transition luminance values to the second luminance value.
In the above description, it has been mentioned that in the display method according to the embodiment of the present invention, the luminance value of the display screen of the electronic device may be set to change regularly between the first luminance value and the second luminance value, and in the embodiment of the present invention, such regular change includes two aspects, that is, when the luminance value of the display screen of the electronic device is adjusted stepwise by at least one transition luminance value, the luminance value of each step is adjusted to be at equal luminance value intervals, or to be at equal time intervals, or to include both. For example, assume that a first luminance value of an electronic device is its current luminance value and a second luminance value is 60% of the first luminance value, and at least one transition luminance value is set between the first luminance value and the second luminance value, which may be 90%, 80%, and 70% of the first luminance value. Therefore, when the brightness value of the display screen of the electronic device continuously changes between the first brightness value and the second brightness value, the change of the brightness value of each level is 10% of the first brightness value, so that the uniform change of the brightness value is realized, the user experience can be enhanced on one hand, the configuration of the system can be simplified on the other hand, and the large system burden is avoided.
Further, in the case where the adjustment of the luminance value of each stage is at equal time intervals, the change of the luminance value of each stage may be set to a fixed time, and here, in the embodiment of the present invention, the change time of the luminance value of each stage may be set according to the number of transition luminance values and the specific relationship of the first luminance value and the second luminance value. For example, when the difference between the first luminance value and the second luminance value is large and the number of transition luminance values is small, the change time of the luminance value of each level can be set to be long because the change of the luminance value of each level is relatively large, so that a user can have sufficient time to adapt to the change of the luminance value on the display screen of the electronic device, and uncomfortable feeling can not be caused. When the difference between the first brightness value and the second brightness value is small and the number of the transition brightness values is large, the change time of the brightness value of each level can be set to be short due to the fact that the change of the brightness value of each level is small, so that the brightness value of the display screen of the electronic device can be changed from a high brightness value to a low brightness value as soon as possible, and the energy consumption of the backlight unit of the electronic device can be remarkably reduced under the condition that a user uses the electronic device in a short time.
In a specific example, assuming that an electronic device has a maximum brightness value of 255 and the minimum unit of brightness value adjustment is 1, that is, the brightness value may only have an integer value, when the display method according to the embodiment of the present invention is adopted on the electronic device, the first brightness value may be set to the maximum brightness value of the electronic device, and the second brightness value is 60% of the maximum brightness value, that is, 153, and the change interval of the brightness value is set to 1 unit brightness value, that is, 1 per brightness value change. According to experimental results, the variation time of the luminance value per level is preferably 0.5 seconds to 1 second, wherein if the variation time of the luminance value per level is less than 0.5 seconds, a significant increase in a burden of a system is caused due to an excessively frequent variation of the luminance value, and if the variation time of the luminance value per level is more than 1 second, when a user uses the electronic apparatus for a short time, for example, when the user uses the electronic apparatus for only several minutes, a variation of the luminance value of the display screen of the electronic apparatus from a first luminance value to 60% thereof may not be achieved within the time, and only a variation of the luminance value of the display screen of the electronic apparatus from the first luminance value to 80% or 90% thereof may be caused, thereby weakening an effect of reduction of power consumption.
Here, it will be understood by those skilled in the art that various values of the luminance values and the time in the above examples may be modified according to the practical application, and the embodiment of the present invention is not intended to limit in any way.
In the display method, the step of detecting whether the state of the electronic device satisfies a predetermined condition specifically includes: detecting an application currently being displayed on the electronic device; and under the condition that the state of the electronic equipment meets the preset condition, the step of automatically adjusting the brightness value of the display screen specifically comprises the following steps of: determining whether the application currently being displayed is a predetermined application, and adjusting the brightness value of the display screen in case the application currently being displayed is the predetermined application.
As described above, since a change in the luminance value of the display screen of the electronic device is easily noticeable by the user, in the display method according to the embodiment of the present invention, it may be further set to determine whether to adjust the luminance value of the display screen based on the application currently being displayed on the electronic device. For example, when the application currently being displayed on the electronic device relates to a dynamic picture display, such as video playing, Flash animation, games, and the like, such adjustment of the brightness value is less noticeable by the user, whereas when the application currently being displayed on the electronic device relates to a static picture display, such as browsing of a static web page, browsing of text, and the like, the user easily perceives a change in the brightness value on the display screen of the electronic device. Thus, by setting a conditional continuous change of the luminance value of the display screen of the electronic device, the user experience may be further enhanced, such that the user is as unaware of the change of the luminance value as possible.
Here, if the electronic device is an electronic device that supports only a single task, an application currently running on the electronic device is an application currently being displayed, whereas if the electronic device is an electronic device that supports multiple tasks, it is necessary to detect which application is an application currently being displayed among multiple applications currently running on the electronic device. In addition, in the electronic device supporting multitasking, if a plurality of applications are running, the plurality of applications may be displayed in a window or in a full screen, and at this time, if a certain application is currently displayed in a full screen, the application is determined, and when a plurality of applications are simultaneously displayed in a window, the determination may be performed based on the plurality of applications. For example, the determination may be made simply in terms of the number of applications that are satisfied, i.e., if a majority of the applications currently displayed in the window, e.g., two of the three applications, satisfy a predetermined condition, an automatic adjustment of the brightness value of the display screen of the electronic device is made. In addition, it is also possible to further judge the proportion of the area of the screen occupied by the application display, that is, if the applications occupying most of the area of the display screen satisfy a predetermined condition, to perform automatic adjustment of the luminance value of the display screen of the electronic device. Here, it may be understood by those skilled in the art that the embodiments of the present invention are not limited thereto at all.
In the display method, the step of determining whether the application currently being displayed is a predetermined application specifically includes: detecting a frame rate of a display result of an application currently being displayed on the display screen; the step of determining whether the application currently being displayed is a predetermined application specifically includes: in the event that the frame rate is greater than a predetermined threshold, it is determined that the application currently being displayed is a predetermined application.
In the above, it has been mentioned that the automatic adjustment of the brightness value is preferably performed when the application currently being displayed on the electronic device relates to a dynamic picture display, whereas whether the application currently being displayed is a dynamic picture display may be detected by a frame rate, i.e. for a video-like application, the frame rate of its display result on the display screen may be larger than a certain threshold. Of course, in the display method according to the embodiment of the present invention, the predetermined threshold may be arbitrarily set, for example, the predetermined threshold may be set to a lower threshold, for example, a few frames per second, even a few frames per second or a few frames per several tens of seconds, so that, even for a relatively static screen display in which a user browses a web page, when the user browses the web page quickly, a change in the frame rate thereof may satisfy an automatic adjustment condition of the luminance value of the display screen of the electronic device, thereby automatically adjusting the luminance value of the display screen. Here, as can be understood by those skilled in the art, in the display method according to the embodiment of the present invention, the setting of the predetermined condition for performing automatic adjustment may be comprehensively considered according to the user experience and other parameters in the display method according to the embodiment of the present invention, so that the user can obtain a satisfactory display effect to the greatest extent while achieving the reduction of energy consumption.
According to another aspect of the embodiments of the present invention, there is provided an electronic device having a display screen, the electronic device further including: a controller configured to obtain a first luminance value of the display screen; obtaining a second brightness value of the display screen, wherein the second brightness value is lower than the first brightness value and greater than zero; detecting whether the state of the electronic equipment meets a preset condition; and automatically adjusting the brightness value of the display screen so that the brightness value continuously changes between the first brightness value and the second brightness value when the state of the electronic device meets a predetermined condition.
Fig. 2 is a schematic block diagram illustrating an electronic device according to an embodiment of the present invention. As shown in fig. 2, the electronic device 100 has a display screen 110, and the electronic device 100 further includes: a controller 120 connected to the display screen 110 and configured to obtain a first brightness value and a second brightness value of the display screen 110, wherein the second brightness value is lower than the first brightness value and greater than zero; detecting whether the state of the electronic device 100 meets a predetermined condition; and automatically adjusting the brightness value of the display screen 110 so that the brightness value continuously changes between the first brightness value and the second brightness value in case the state of the electronic device 100 satisfies a predetermined condition.
By the display method and the electronic equipment, the brightness value of the display screen of the electronic equipment can be continuously adjusted based on the state of the electronic equipment, so that the energy consumption of the electronic equipment is reduced.
The invention has been described in detail with reference to specific embodiments thereof. It will be apparent, however, to those skilled in the art that modifications and substitutions can be made to the embodiments without departing from the spirit of the invention.
