Implement one
Referring to Fig. 1, Fig. 1 is that the application adjusts the process flow diagram of the embodiment of the method 1 of screen backlight based on displaying contents.The technical scheme that the present embodiment provides comprises the following steps:
Step 101: whether monitor terminal equipment upgrades displaying contents to buffer zone; If so, execution step 102.
Terminal device can be the equipment that mobile phone, smart mobile phone, flat board, notebook, computing machine etc. have display screen.Screen is all LCD (Liquid Crystal Display now, LCDs), and LCD backlight be the greatest factor that affects power consumption of screen, account for 85% of screen overall power, reducing brightness is the Main Means that reduces backlight power consumption.The present embodiment adopts exactly and reduces brightness means reduction backlight power consumption.
During user's operation terminal device, terminal device can first be stored in buffer zone by content to be displayed, more successively content to be displayed in buffer zone is presented on the screen of terminal device.In terminal device, various types of application can be installed, the application of applying, play such as paying, office application, terminal device system carry application etc.In practical application scene, user operates certain application, when application has just entered or upgraded displaying contents, before data are also not ready for, often shows that blank content is as transition displaying contents.Such as before user's click browser enters browser interface, demonstration be that blank interface user accesses game application, before entering the main interface of game, terminal device can show blank content; User clicks while loading new interface for another example, and before new interface data is also not ready for, terminal device shows blank content.
Whether step 102, analyzing described displaying contents is blank content.If so, execution step 103.
Step 103, reduces screen intensity.
When terminal device has new content to show, first this displaying contents is flushed to buffer zone, after execution step 101 finds that terminal device upgrades displaying contents, judge whether this displaying contents is blank content.Consider, terminal device usually flushes to buffer zone by content to be displayed with picture form at present, and therefore, the content to be displayed in buffer zone is all images.Due to when application has just entered, or in refresh data process, in this type of scene, using blank image as content to be displayed, blank image refers to the not image of carry information.For user, blank image does not have any substantial role, some application suppliers can be arranged to this blank image the blank image of certain background colour, such as being set to black blank image, the blank image of the random colors such as light blue blank image, this blank image is a transfer image acquisition before data interface image shows.
Judge whether an image is blank image, can judge that whether image is blank by black and white ratio, can also judge by other means whether an image is blank image.
Based on this, this step can also realize according to following optimal way: whether analyze described displaying contents is a blank image.If analyze described displaying contents, be exactly a blank image, show that content that terminal device be about to show is for user's actual value not, now reduce screen intensity and can either reduce power consumption and do not affect again user and experience.If be applied in, just to enter time of stage or refresh data stage buffering long, within a period of time, content to be displayed is blank image always, can will perform step for the first time the screen intensity of the 103 o'clock screen intensity when follow-up all blank image show; Also can, for when showing each blank image, all reduce screen intensity one time.
In addition, this step can also realize according to following optimal way: whether the brightness of analyzing described displaying contents is greater than threshold value, if so, shows that described displaying contents is blank content.Brightness by displaying contents judges whether it is blank content, because the brightness of blank content is often greater than the brightness of non-blank-white content, therefore, can judge whether displaying contents is blank content by brightness size.This threshold value can, according to the empirical value setting of the blank content brightness of practical application scene, also can be changed according to the actual requirements.
In the process of execution analysis operation, can check screen intensity value, then perform step at 103 o'clock screen intensity value is set less than the screen intensity value of checking.Such as before execution step 103, check that screen intensity is 100%, step 103 is specially and screen intensity value is set is less than 100%.Consider if the unexpected reduction of screen intensity may affect user too much and experience, can preset a screen intensity and reduce scope, screen intensity reduction is set to be carried out in this preset range, such as this default screen intensity reduction scope 60% ￣ 90% that is former screen intensity, perform step 103 o'clock needs and follow this preset range, must not surpass this scope.Above-mentioned scope is only an exemplary range, can change according to concrete scene demand in actual applications.
By above-described embodiment, can find out: the present invention is based on the method that displaying contents is adjusted screen backlight, consider the impact of displaying contents on brightness, when the displaying contents of terminal device is blank content, reduce screen intensity, the scene that while using terminal device due to user, displaying contents is blank content occurs more frequent, therefore, this processing mode can either reduce power consumption can not affect again user's experience.
Consider that existing application developer is usually applied while just having entered or refresh data display interface is before set to white blank image, when user uses terminal device, when terminal device screen intensity is identical with surrounding environment brightness, the scheme that reduces power consumption in prior art just cannot reach the effect that reduces power consumption according to the brightness of the automatic brightness adjustment screen of environment.
Based on this, the invention provides preferred version, this preferred version is considered, when user uses terminal device screen intensity identical with surrounding environment brightness, when if the displaying contents of terminal device is white blank image, white is obviously dazzling than other colors,, when white blank image shows, screen display is brighter, the not only power consumption but also affect user and experience of this display mode.Under this application scenarios, if can reduce screen intensity, improve user's experience and reduce again equipment power dissipation.Below by bis-pairs of these preferred versions of embodiment, be further explained explanation.
