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.
Seeing also Fig. 1, is the schematic flow sheet of the present invention's method of postponing to shut down.The method that the present invention postpones to shut down may further comprise the steps:
Step 10: press the switch for the treatment of of TV remote controller, video screen display delay shutdown menu;
In this step, when the user finishes watching TV, press remote controller treat switch the time, video screen can eject a menu: " please import the time that needs to postpone shutdown! ".In embodiments of the present invention, this TV is a LCD TV, and this video screen is a liquid crystal display screen.
Step 20: set the delay unused time according to postponing the shutdown menu;
In this step, the user can be by the time of wanting by the numerical key above remote controller input to postpone, such as " 5 minutes " etc.
Step 30: judging to postpone whether the unused time is 0, is 0 if postpone the unused time, execution in step 40; If postponing the unused time is not 0, execution in step 50;
Wherein, postpone the unused time if the user sets, then the system default delay unused time is 0.
Step 40: postpone the shutdown menu and keep certain hour, and execution in step 80;
Wherein, the time that postpones the reservation of shutdown menu can be set according to user's request, and in embodiments of the present invention, the time that delay shutdown menu keeps is 10 seconds.
Step 50: by complete white and the brightest picture of master chip output of TV;
Please further consulting Fig. 2, is the fundamental diagram that the present invention's method of postponing to shut down is adjusted display frame.The operation principle that the method that the present invention postpones to shut down is adjusted display frame is: the master chip of television terminal is with 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 the 8bit screen, rgb value all is 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 that the present invention's method of postponing to shut down is adjusted backlight illumination.The operation principle that the method that the present invention postpones to shut down is adjusted backlight illumination is: by regulating TV master chip PWM (pulse width modulation, Pulse Width Modulation) Shu Chu different duty, regulate the work period of INVERTER (inverter), thereby change the time span of liquid crystal display screen backlight open, to realize making the adjustable purpose of lighting tube brightness of liquid crystal display screen; For example, when the duty ratio of TV master chip PWM output is maximum 100% the time, the lighting tube brightness maximum of liquid crystal display screen.The PWM in fact frequency that changes of the high-level retention time by changing the single-chip microcomputer delivery outlet and low level retention time and high-low level realizes that we only need output high level time 100%, and the output low level retention time is 0 to get final product.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, then we just feel brighter, otherwise then dark.If we are made as 100% with duty ratio, promptly only open and be not related to, then can reach backlight the brightest.Certainly, also the PWM frequency can be made as arbitrary value, thereby realize different backlight illuminations, to play the effect of television lighting.
Step 70: the delay unused time timing that timer is set according to the user;
In this step, carry out timing according to the delay unused time that the user sets, the user just can utilize the television lighting in time of delay to go to the bedroom, arrive postpone the unused time after TV can shut down automatically.
Step 80: TV shuts down automatically after arriving the time of setting.
Seeing also Fig. 4, is the structural representation of the present invention's television terminal of postponing to shut down.The television terminal that the present invention postpones to shut down comprises timer, master chip, TCON (time schedule controller of screen) plate, inverter and display screen.Wherein, can be provided with by timer and postpone the unused time, by master chip RGB (color mode) value of LVDS (low-voltage differential signal, Low-Voltage Differential Signaling) output signal is made as and equate and be maximum, such as the 8bit screen, rgb value all is 255; 10bit screen is 1023 etc., and this LVDS signal is directly exported to the 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) Shu Chu different duty, regulate the work period of inverter, thereby change the time span that display backlight is opened, to realize making the adjustable purpose of lighting tube brightness of display screen; For example, when the duty ratio of TV master chip PWM output is maximum 100% the time, the lighting tube brightness maximum of display screen.The PWM in fact frequency that changes of the high-level retention time by changing the single-chip microcomputer delivery outlet and low level retention time and high-low level realizes that we only need output high level time 100%, and the output low level retention time is 0 to get final product.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, then we just feel brighter, otherwise then dark.If we are made as 100% with duty ratio, promptly only open and be not related to, then can reach backlight the brightest.Certainly, also the PWM frequency can be made as arbitrary value, thereby realize different backlight illuminations, to play the effect of television lighting.
In embodiment of the present invention, television terminal is the LCD TV terminal, and display screen is a liquid crystal display screen.
Method that the present invention postpones to shut down and television terminal utilize the timer of television set to increase time-delay, simultaneously, can adjust on-screen displays, backlight illumination etc. according to user preferences, thereby realize the effect of television lighting, promote user's experience greatly.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
