Interval t is used as bound-time when switching to the second frame picture with the second GTG Y from the first GTG X the first frame picture.
It is appreciated that when the first GTG X is more than the second GTG Y, bound-time t is from the from brightness-time graph
What the lower liter edge that one frame picture switches to the second frame picture calculated or measured.
In step s 5, the bound-time t calculated is compared with default bound-time T.Such as people in the art
As member understands, bound-time is shorter, shows the upset of liquid crystal molecule or rotates faster, the speed of liquid crystal panel switch frame picture
Degree is faster, so that high-quality video or 3D rendering are preferably shown, and if bound-time is oversize, then it is possible that picture
Delay.Default bound-time T can equally enter according to Its Relevant Technology Standards, display demand, display effect or the experience of gauger
Row selection is set, for example, can be 16ms, 10ms, 8ms, 5ms, 4ms or 2ms, be limited herein.

Bound-time t, compare the bound-time t that calculates and default bound-time T, and according to comparative result to liquid crystal display panel
Display effect be adjusted.
In one example, when the bound-time t calculated is less than or equal to default bound-time T, show current aobvious
It is gratifying to show effect, then the control device 7 for being connected to drive device 3 and storage device 8 maintains default driving voltage table
In corresponding driving voltage it is constant.On the other hand, when the bound-time t calculated is more than default bound-time T, control device
In GTG switching in the default driving voltage table of 7 adjustment, the driving voltage applied when such as switching to the second GTG from the first GTG, and
Liquid crystal display panel is driven to show predetermined pattern again using the driving voltage after adjustment, until the bound-time calculated is less than

Control signal is sent to increase in default driving voltage table with driving electricity from the first GTG X to the second GTG Y switching is corresponding
Pressure, thereby speeds up liquid crystal molecule and is rotated or turned over the time, reduce bound-time t, this is shown in figure 3.As illustrated,
The driving voltage that first frame picture of the display with the first GTG X is used is Vx, and shows the second frame with the second GTG Y
The driving voltage that picture is used is Vy, first increases driving voltage from Vx when switching to the second frame picture from the first frame picture
To Vz, wherein Vz2 ＞ Vz1, but it is changed into Vy from Vz again, then from the first stable frame picture to the mistake of the second stable frame picture
Cross or bound-time shortens, Vz is bigger, and bound-time when frame picture switches is shorter.Control device 7 is constantly adjusted from first
Frame picture switches to the driving voltage used during the second frame picture, and drives liquid crystal again using the driving voltage after adjustment
Show Display panel predetermined pattern, until the bound-time calculated is less than default bound-time.Similarly, it is more than in the first GTG
During the second GTG, can reduce in default driving voltage table with from the first GTG to the switching of the second GTG it is corresponding driving electricity
Pressure, such as uses bigger negative voltage.
The driving voltage Vz used when the switching of frame picture or saltus step is generally no greater than desired value (that is, the driving electricity of next frame
Pressure) Vy (100+m) %, can be directed to and be separately provided m values per GTG two-by-two, it may be set between 10~20, m values and show
Show that the concrete property of panel is related.
The step of adjusting driving voltage can be included with driving liquid crystal display panel again until the bound-time t calculated
Driving voltage after the adjustment used during less than default bound-time T replaces corresponding driving electricity in default driving voltage table
Pressure.For example, the storage device 8 for storing default driving voltage table is erasable, such as EEPROM, control device 7 or other
Control unit is erasable to storage device progress according to the regulation result of display effect, replaces corresponding with the driving voltage after adjustment
Old driving voltage, to set up the driving voltage inquiry table that liquid crystal display panel can be driven to realize good display effect.Can
To understand, control device 7 can include the composition portion of the timing controller either timing controller of liquid crystal display panel
Point.
The method and system of the display effect of adjustable liquid crystal display display panel can also be measured according to an embodiment of the invention
