The process that time, liquid crystal molecule deflect is also required to the regular hour, namely shows that a frame is drawn in display drive control display panel
When face, being shown since being opened to picture display driving has certain response time, i.e., is all needed when being switched over per frame picture
Want the response time.The display that display driving carries out next frame picture when carrying out black picture display, is being opened in the embodiment
Deflection takes place in driving, the liquid crystal molecule controlled in pixel, and next frame picture has been carried out when carrying out black picture display
Driving is equivalent to the time for saving part response, improves screen switching speed, further improve user's visual experience.
Further, the present invention also provides a kind of display device, Figure 15 is that display device provided in an embodiment of the present invention is shown
It is intended to, as shown in figure 15, display device includes the display panel 100 that any embodiment of the present invention provides.The embodiment of the present invention carries
The display device of confession can be any electronic product with display function, including but not limited to following classification：Television set, notes
This computer, desktop displays, tablet computer, digital camera, mobile phone, Intelligent bracelet, intelligent glasses, Vehicular display device, medical treatment
Equipment, industrial control equipment, touch interactive terminal etc..
By above-described embodiment it is found that the display panel and its driving method and display device of the present invention, have reached as follows
Advantageous effect：
In the present invention in the pixel column adjacent with special-shaped boundary, in adjacent two pixel columns a pixel column relative to
One other pixel row inside contracts a pixel, and the present invention can be obviously reduced compared with the relevant technologies close to special-shaped boundary side
The size for the step that two adjacent pixel columns are formed mitigates edge sawtooth sense when display.In addition, pixel passes through in the present invention
The mode that sequence is shown realize colour mixture show namely the present invention in single pixel can realize the displays of different colours, and it is related
The display of different colours could be realized by needing the sub-pixel of at least three different colours to constitute a pixel in technology.Energy of the present invention
It is enough obviously improved the PPI of display panel, promotes display effect.
Although some specific embodiments of the present invention are described in detail by example, the technology of this field
Personnel it should be understood that the above example merely to illustrating, the range being not intended to be limiting of the invention.Those skilled in the art
Member is it should be understood that can without departing from the scope and spirit of the present invention modify to above example.The present invention's
