Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of method of liquid crystal display, and referring to Fig.1, in one embodiment, the method for the liquid crystal display includes:
Step S101 obtains display visibility window signal compatible with screen size frame by frame and is cached to frame buffer zone；
In the present embodiment, liquid crystal display needs further that this is original when getting original display signal
Signal is handled, and is allowed to be adapted with the screen-sized of liquid crystal display, then can just be shown on the screen
Show.
In the present embodiment, display visibility window signal (Display Evident Window, DEW) is obtained frame by frame, then
It is stored into frame buffer zone.
Every frame is shown that visibility window signal carries out calculation process according to mean pixel distance, is corresponded to by step S102
Display window signal and cache so that and the display window signal to should be greater than and corresponding display visibility window；Namely
It is to say, after the calculation process, corresponding display window described in display window signal is greater than display visibility window signal institute
Corresponding display visibility window.Wherein, display visibility window refers to the size that display window signal is shown by display screen, and
Display window refer to display window signal without being bound by the size of display screen, and the size that should be shown.
In the present embodiment, the mean pixel distance d of liquid crystal display is calculated first, display visibility window signal
Size is just adapted to the size of screen, that is to say it is equal, then according to mean pixel distance amplification display visibility window signal,
This is enlarged into the display area of amplification display visibility window signal, that is to say the area of display visibility window, obtains display window
Signal (Display Window, DW), for example, will display visibility window signal in left-right direction respectively stretch 16 mean pixels away from
From d, 8 mean pixel distance d are respectively stretched along the vertical direction, and the display length of the display window signal obtained in this way is that display can
The length of window signal is seen plus 32 mean pixel distance d, and display width is to show the length of visibility window signal plus 16
A mean pixel distance d.
In the present embodiment, when liquid crystal display shows a frame signal, while above-mentioned display visible window message is shown
Number and display window signal it can be cached with corresponding display visibility window signal after stretching obtains display window signal
Signal is shown for a frame.
Step S103 is opposite for unit with the mean pixel distance by every frame display window signal when being shown
It is moved on the screen in corresponding display visibility window signal, so that the track of display window signal movement constitutes and follows
Ring track.
In the present embodiment, before showing that a frame shows signal, every frame display window signal is carried out by mean pixel distance
It is mobile, i.e., it shows that visibility window signal is moved relative to a corresponding frame, such as moves horizontally 8 or 16 to the left or to the right
Mean pixel distance d, or 4 or 8 mean pixel distance d of vertical shift etc. upward or downward, then show display together
Visibility window signal and display window signal corresponding, after movement are a frame picture.Due to the movement of display window signal, because
This, can dynamically change the voltage that liquid crystal molecule of the liquid crystal display on the moving direction is born.
Further, since display window signal is that display visibility window signal carries out the amplified signal of display area,
The two is essentially identical, only shows that the display area of visibility window signal is less than the display area of display window signal, therefore,
Display window signal carries out small movement, and the voltage that liquid crystal molecule is born will not change a lot, only with aobvious
Show that the movement of window signal is changed into the voltage that neighbouring liquid crystal molecule is born, shown picture effect is not also substantially by shadow
It rings.
In addition, during display window signal is mobile, being shown visible since the display area of display window signal is big
Window signal is always located in the magnitude range of display window signal, therefore can prevent the generation of black surround.
In the present embodiment, the mobile track of display window signal constitutes circulation track, such as first frame display window signal
Level is moved to the left, and the second frame display window signal moves straight up, and third frame display window signal level moves right, the
Four frame display window signals are mobile etc. straight down, also, what is moved horizontally is equidistant, for example 8 or 16 mean pixels
The distance of distance d, vertical shift are also equal, and for example 4 or 8 mean pixel distance d, the display of first to fourth frame as a result,
The mobile track of window signal constitutes circulation track, which is rectangular path, in such manner, it is possible to make up and down direction and left and right
The liquid crystal molecule in direction is pressurized uniformly.In addition, the present embodiment is not limited to above-mentioned move mode, as long as can make liquid crystal point
Son is pressurized uniform mode in the protection scope of the present embodiment, such as display window signal can be moved with certain slope
Dynamic, circulation track is positive triangular trajectory or prismatic track also can achieve up and down direction and the liquid crystal molecule of left and right directions is equal
Be pressurized uniform purpose.
Compared with prior art, the present embodiment obtains display visibility window signal compatible with screen size first, so
Calculation process is carried out to display visibility window signal afterwards and obtains display window signal, it, will when liquid crystal display shows signal
Every frame display window signal carries out minute movement relative to corresponding display visibility window signal on the screen, passes through this side
Formula can dynamically change the electricity that liquid crystal molecule is born under the premise of guaranteeing that the picture effect of display is substantially unaffected
Pressure, and the generation of black surround can be prevented, the mobile track of display window signal constitutes circulation track, liquid crystal molecule can be made to be pressurized equal
It is even, improve the service life of liquid crystal display.
