A kind of structural representation of drive circuit that Fig. 3 provides for the embodiment of the present invention two.
Specific embodiment
For making those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings the present invention is carried
For driving method and its drive circuit, display floater be described in detail.
Embodiment one
A kind of flow chart of the driving method of display floater that Fig. 1 provides for the embodiment of the present invention one.As shown in figure 1, frame
Picture includes odd field picture and even field picture, and described driving method includes：
Step 1001, the odd-numbered line grid line being pointed to odd field picture are scanned successively, adjacent odd-numbered line grid line
There is between scanning default very first time interval.
Step 1002, the even number line grid line being pointed to even field picture are scanned successively, adjacent even number line grid line
There is between scanning default second time interval.
The driving method that the present embodiment provides arranges very first time interval between the scanning of adjacent odd-numbered line grid line,
Between the adjacent scanning of even number line grid line, the second time interval is set, thus sweeping the odd-numbered line grid line among prior art
Retouching the time interval even partition and the scanning of even number line grid line between is to be spaced and between multiple very first time multiple very first times
Every.Time interval between scan period carries out being uniformly distributed and can avoid the occurrence of scintillation, thus improving display picture
Display quality.
Fig. 2 is the sequential chart of driving method shown in Fig. 1.As shown in Fig. 2 a frame image time includes odd field image time

Line is scanned, and the pulse width that antithesis several rows grid line is scanned is the 4th time interval T4.In the present embodiment, the described 3rd
Time interval T3 is identical with described 4th time interval T4, thus by the scanning of the odd-numbered line grid line among prior art and even number
Time interval even partition between the scanning of row grid line is that interval T1 of multiple very first times is spaced T2 with multiple very first times.Sweep
Retouch the time interval between the cycle and carry out being uniformly distributed and can avoid the occurrence of scintillation, thus improving the display product of display picture
Matter.
In the present embodiment, described 3rd time interval is 60%- with the second buffer level of described 4th time interval
100%.Optionally, described second buffer level is 90%-100%.Preferably, described second buffer level is 90%.
Within one frame picture, during the normal display of display image in addition to, during the horizontal blanking also including not showing image
(horizontal blanking time).Although being the blank time not showing image during blanking, drive circuit is in this section
Still continue output signal that is to say, that drive circuit still constantly consumes electric current within time, virtually improve driving
The power consumption of circuit.The first buffer level that the present embodiment provides is exactly to set for the power consumption reducing during horizontal blanking
Put.In order to reduce power consumption further, the second buffer level that the present embodiment provides can reduce normally showing of display image
Power consumption during showing, such that it is able to be prevented effectively from the current waist of drive circuit, reduces the power consumption of whole drive circuit,
Do not interfere with the image quality during normal display simultaneously.
In the present embodiment, described 3rd time interval is 60%- with the second buffer level of described 4th time interval
100%.Optionally, described second buffer level is 60%-80%.Preferably, described second buffer level is 60%.Cause
This, the second buffer level that the present embodiment provides can reduce the power consumption during the normal display of display image, such that it is able to
It is prevented effectively from the current waist of drive circuit, reduces the power consumption of whole drive circuit, do not interfere with normal display simultaneously
The image quality of period.
Among the driving method that the present embodiment provides, frame picture includes odd field picture and even field picture, described driving
