Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention,, the zooming of display content of whole screen is switched to the subregion screen, control the pairing backlight continuous firing of this subregion screen, close or dim the pairing backlight of other subregion screen according to the screen switching command.
Fig. 1 shows the realization flow of the method for controlling backlight thereof that the embodiment of the invention provides, and its detailed step is as described below:
In step S101, receive the screen switching command, wherein, this screen switching command comprises key command, phonetic control command and the automatic triggering command that the user imports.
In embodiments of the present invention, TV programme one collection or a few part of watching as the user finish, the advertisement that needs interval or intercut a period of time just continues to play, and the user loses interest in to current advertisement of intercutting or other guide, but the current TV programme of watching of fear missing again, so user's facility is imported a screen switching command with button, current display screen is switched to the subregion screen by whole screen, displaying contents by the whole screen of this subregion screen display, above-mentioned is that example describes with the TV programme, but not in order to restriction the present invention.
In embodiments of the present invention, above-mentioned screen switching command also can be phonetic control command or automatic steering order, and for example, the user can import this phonetic control command by microphone; Also can be by the mode of automatic triggering command, be that system exists a detection module, have a rest or during the time of commercial breaks, trigger sending this and instruct central processing unit automatically when detecting current mediating, control switches to the subregion screen with whole screen, but not in order to restriction the present invention.
In step S102, current display screen is switched to the subregion screen by whole screen, the displaying contents of the whole screen of subregion screen display.
In embodiments of the present invention, in advance whole screen is carried out the subregion screen divider, can be divided into N, each subregion screen is the 1/N of whole screen area, the corresponding backlight of subregion screen after being provided with simultaneously and dividing, backlight is controlled pairing subregion screen separately.
In embodiments of the present invention, displaying contents is switched to the subregion screen, this subregion screen can be positioned at central authorities or other positions of whole screen, but not in order to restriction the present invention.
In step S103, the pairing backlight continuous firing of control subregion screen, and the pairing backlight of the subregion screen outside the subregion screen is closed or is dimmed in control.
In embodiments of the present invention, after present displayed content was presented at the subregion screen, the backlight of this subregion screen worked independently, and the backlight of other subregion screen correspondences dims accordingly or closes, to save backlight power consumption.
In embodiments of the present invention, when TV programme of watching as the user or user's interest program begin to play, the screen that receives the user recovers switching command, this screen recovers switching command to be realized by the mode of above-mentioned key command, phonetic control command or automatic triggering command equally, current display screen is switched to whole screen by the subregion screen, and it is in running order to control the pairing backlight of all subregion screens.
In embodiments of the present invention, can adopt three R, G, B light emitting diode as backlight.
Fig. 2 shows the structured flowchart of the backlight control system that the embodiment of the invention provides, for convenience of explanation, only provided the part relevant with the embodiment of the invention among the figure, wherein, backlight control system can be software unit, hardware cell or the software and hardware combining unit that is built in electronic display unit.
In embodiments of the present invention, 14 pairs of whole screens of screen area division module carry out the subregion screen divider; Backlight is provided with the corresponding backlight of subregion screen after module 15 settings are divided with screen area division module 14, and backlight is controlled its pairing subregion screen separately.
