Abstract
The invention discloses a method for solving shutdown image sticking of a tablet computer liquid crystal display screen, and relates to the technical field of a tablet computer shutdown control method, for solving the technical problem of image sticking existing after a liquid crystal display screen of a tablet computer is powered off. According to the method, when the tablet computer is shut down, after backlight is turned off, the following processing is successively executed: 1, a system outputs white image signals to the liquid crystal display screen; 2, the system outputs black image signals to the liquid crystal display screen; and 3, the system terminates outputting the signals to the liquid crystal display screen, and a power source is turned off. According to the invention, when the tablet computer is shut down, the system successively sends the white image signals and the black image signals to the liquid crystal display screen, the whole liquid crystal display screen is pure black before shutdown, the image sticking is prevented from being seen, and the display quality of the tablet computer is improved.
Description
Technical field
The present invention relates to panel computer shutdown control method technical field, be specifically related to flat panel Liquid Crystal display screen shutdown image residue processing method.
Background technology
Panel computer application is more and more extensive, and from consumption to commercial affairs, from game to education, all trades and professions have begun to popularization and application, and each manufacturer the most constantly promotes the quality of panel computer.Existing LCDs is after system stops providing signal and power supply to it, and due to the characteristic of TFT screen, the electric charge of liquid crystal capacitance will not be released, as shown in Figure 1 immediately.
After LCDs power-off, the electric charge of liquid crystal capacitance will not be released immediately, and this is that the characteristic of TFT screen cannot be improved, and causes the picture before shutdown can remain display on screen, leverages the using effect of panel computer.
Summary of the invention
It is an object of the invention to solve existing panel computer after LCDs power-off, there is the technical problem of picture residual, and propose a kind of method solving flat panel Liquid Crystal display screen shutdown image residue.
For solving technical problem proposed by the invention, the technical scheme of employing is: a kind of method solving flat panel Liquid Crystal display screen shutdown image residue, it is characterised in that described method is when panel computer shuts down, and after backlight is closed, performs successively to process as follows:
1), system exports white picture signal to LCDs；
2), system is to LCDs output black picture signal；
3), system closure is to LCDs output signal, power-off.
After system is to LCDs output white picture signal, the time system through 3 frames gives LCDs output black picture signal again.
After system is to LCDs output black picture signal, the time system through 3 frames terminates to LCDs output signal, power-off.
The invention have the benefit that the present invention passes through when panel computer shuts down, system in succession sends white picture signal and black picture signal to LCDs, making whole LCDs is ater before being powered off, it is to avoid see the residual of image, promotes the display quality of panel computer.
Accompanying drawing explanation
Fig. 1 is the voltage time figure of TFT screen after LCDs power-off；
Fig. 2 is the electric connecting relation figure between panel computer system plate and LCDs；
Fig. 3 is that the present invention shuts down sequential chart.
Detailed description of the invention
Below in conjunction with accompanying drawing and currently preferred specific embodiment, the present invention is further described.
With reference to shown in Fig. 2 and Fig. 3, it is when panel computer shuts down that the present invention solves the method for flat panel Liquid Crystal display screen shutdown image residue, after backlight is closed, performs successively to process as follows:
1), system exports white picture signal to LCDs；
2), after the time of 3 frames, system is to LCDs output black picture signal；
3), again after the time of 3 frames, system closure is to LCDs output signal, power-off.
The invention enables whole LCDs is ater before being powered off, after shutdown process terminates, screen does not have the residual of image, improves the display quality of panel computer.
Claims (3)
1. the method solving flat panel Liquid Crystal display screen shutdown image residue, it is characterised in that described method is when panel computer shuts down, after backlight is closed, performs to process as follows successively:
1), system exports white picture signal to LCDs；
2), system is to LCDs output black picture signal；
3), system closure is to LCDs output signal, power-off.
A kind of method solving flat panel Liquid Crystal display screen shutdown image residue the most according to claim 1, it is characterised in that: after system is to LCDs output white picture signal, the time system through 3 frames gives LCDs output black picture signal again.
A kind of method solving flat panel Liquid Crystal display screen shutdown image residue the most according to claim 1 and 2, it is characterized in that: after system is to LCDs output black picture signal, time system through 3 frames terminates to LCDs output signal, power-off.
