Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, is the schematic flow sheet of the method for delaying shutdown of the present invention.The method of delaying shutdown of the present invention comprises the following steps:
Step 10: press the switch for the treatment of of TV remote controller, video screen display delay shutdown menu;
In this step, when user finishes watching TV, press remote controller when switch, video screen can eject a menu: " please input the time that needs delaying shutdown! ".In embodiments of the present invention, this TV is LCD TV, and this video screen is liquid crystal display screen.
Step 20: set the delaying shutdown time according to delaying shutdown menu;
In this step, user can want the time postponing by pressing the input of numerical key above remote controller, such as " 5 minutes " etc.
Step 30: judge whether the delaying shutdown time is 0, if the delaying shutdown time is 0, execution step 40; If the delaying shutdown time is not 0, execution step 50;
Wherein, if user does not set the delaying shutdown time, the system default delaying shutdown time is 0.
Step 40: delaying shutdown menu retains certain hour, and performs step 80;
Wherein, the time that delaying shutdown menu retains can be set according to user's request, and in embodiments of the present invention, the time that delaying shutdown menu retains is 10 seconds.
Step 50: by a complete white and the brightest picture of master chip output of TV;
Please further consulting Fig. 2, is the fundamental diagram of the method adjustment display frame of delaying shutdown of the present invention.The operation principle that the method for delaying shutdown of the present invention is adjusted display frame is: the master chip of television terminal is by LVDS (low-voltage differential signal, Low-Voltage Differential Signaling) RGB (color mode) value of output signal is made as equal and is maximum, such as 8bit screen, rgb value is all 255; 10bit screen is 1023 etc., and this LVDS signal is directly exported to TCON (time schedule controller of screen, the Timing Controler) plate of LCD TV, thereby makes liquid crystal display screen can show complete white and the brightest picture.Certainly, the rgb value of this LVDS signal output signal can also be set to arbitrary value according to user preferences, thereby realizes different picture brightness.
Step 60: screen backlight is adjusted to high-high brightness;
Please further consulting Fig. 3, is the fundamental diagram of the method adjustment backlight illumination of delaying shutdown of the present invention.The operation principle that the method for delaying shutdown of the present invention is adjusted backlight illumination is: by regulating TV master chip PWM (pulse width modulation, Pulse Width Modulation) different duty of output, regulate the work period of INVERTER (inverter), thereby change the time span of liquid crystal display screen backlight open, to realize the adjustable object of lighting tube brightness that makes liquid crystal display screen; For example, when the duty ratio of TV master chip PWM output is maximum 100%, the lighting tube brightness of liquid crystal display screen is maximum.In fact PWM realizes by the high-level retention time of change single-chip microcomputer delivery outlet and the frequency of low level retention time and low and high level variation, and we only need export high level time 100%, and the output low level retention time is 0.According to the eye storage characteristic of human eye, as long as the frequency of fluorescent tube opening and closing is enough high, human eye is just discovered less than flicker, the ratio of time with the time of closing of unlatching is depended in the brightness that we feel, if the time of opening is long, we just feel brighter, otherwise dark.If we are made as 100% by duty ratio, only open and be not related to, can reach backlight the brightest.Certainly, also PWM frequency can be made as to arbitrary value, thereby realize different backlight illuminations, to play the effect of television lighting.
Step 70: the delaying shutdown time that timer is set according to user regularly;
In this step, the delaying shutdown time of setting according to user is carried out timing, and user just can utilize the television lighting in time of delay to go to bedroom, and after the time, TV can automatic shutdown to arrive delaying shutdown.
Step 80: TV automatic shutdown after the time that arrival is set.
Referring to Fig. 4, is the structural representation of the television terminal of delaying shutdown of the present invention.The television terminal of delaying shutdown of the present invention comprises timer, master chip, TCON (time schedule controller of screen) plate, inverter and display screen.Wherein, can pass through the set timer delaying shutdown time, by master chip, RGB (color mode) value of LVDS (low-voltage differential signal, Low-Voltage Differential Signaling) output signal is made as and be equated and for maximum, such as 8bit screen, rgb value is all 255; 10bit screen is 1023 etc., and this LVDS signal is directly exported to TCON plate, thereby makes display screen show complete white and the brightest picture.Wherein, the rgb value of this LVDS output signal can also be set to arbitrary value according to user preferences, thereby realizes different picture brightness.By regulating TV master chip PWM (pulse width modulation, Pulse WidthModulation) different duty of output, regulate the work period of inverter, thereby change the time span that display backlight is opened, to realize the adjustable object of lighting tube brightness that makes display screen; For example, when the duty ratio of TV master chip PWM output is maximum 100%, the lighting tube brightness of display screen is maximum.In fact PWM realizes by the high-level retention time of change single-chip microcomputer delivery outlet and the frequency of low level retention time and low and high level variation, and we only need export high level time 100%, and the output low level retention time is 0.According to the eye storage characteristic of human eye, as long as the frequency of fluorescent tube opening and closing is enough high, human eye is just discovered less than flicker, the ratio of time with the time of closing of unlatching is depended in the brightness that we feel, if the time of opening is long, we just feel brighter, otherwise dark.If we are made as 100% by duty ratio, only open and be not related to, can reach backlight the brightest.Certainly, also PWM frequency can be made as to arbitrary value, thereby realize different backlight illuminations, to play the effect of television lighting.
In embodiment of the present invention, television terminal is LCD TV terminal, and display screen is liquid crystal display screen.
The method of delaying shutdown of the present invention and television terminal utilize the timer of television set to increase time delay,, can to on-screen displays, backlight illumination etc., adjust according to user preferences meanwhile, thereby realize the effect of television lighting, greatly promote user's experience.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
