End ", " other end " and similar statement are for illustrative purposes only.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
The embodiment of the invention provides a kind of display panels, including substrate, scan line and scan line vertically disposed first
Class data line and with the vertically disposed secondary sources line of scan line, primary sources line and secondary sources line are spaced and parallel
Arrangement；Scan line, primary sources line and secondary sources line are staggered to form the pixel region of multiple array-like arrangements, in base
Multiple active arrays switch that each pixel region is provided with array-like arrangement is corresponded on plate；Along the extending direction of primary sources line
It is correspondingly arranged on multiple pixel units, a portion pixel unit includes at least one active array switch, and another part
Pixel unit is switched including at least two active arrays；On the direction that data line extends in two neighboring pixel unit wherein
Each active array switch of one pixel unit connects primary sources line, each active array switch in one other pixel unit
Connect secondary sources line；It is start-up time when the corresponding pixel unit of scan line is opened, in two neighboring start-up time each the
The data polarity of a kind of data line load is on the contrary, the data polarity phase loaded in each secondary sources line of two neighboring start-up time
Instead；And it is opposite in the data polarity that same start-up time, primary sources line and secondary sources line load.
Wherein, substrate refers to the substrate of outer layer growth, in the production and manufacturing process of substrate, plays and supports and fixes
Effect.Active array switch, which refers to, is set to each pixel region, the transistor for driving pixel electrode.For example, active battle array
Column switch can be thin film transistor (TFT) etc..Multiple battle arrays that scan line, primary sources line and secondary sources line are staggered to form
The pixel region of column-shaped arrangement can be as shown in Figure 1, what two adjacent data lines and two adjacent scan lines were surrounded
Region.Start-up time refers to a certain horizontal scanning line load gate driving signal, drives each active array connecting with the scan line
Switch primary sources line and secondary sources line refer in the same start-up time, primary sources line and secondary sources line
The data polarity of load is on the contrary, for example in the same start-up time, and the data polarity of primary sources line load is positive polarity, then
At this point, the data polarity of secondary sources line load is negative polarity, it should be noted that do not limit primary sources line here
The data polarity of (secondary sources line) is stationary state, in two adjacent start-up times, primary sources line (he second-class number
According to line) polarity invert.
Specifically, multi-strip scanning line intersects respectively with primary sources line and secondary sources line arranged crosswise and surrounds shape
At multiple pixel regions in active array switch.It is arranged successively along each active array switch of scan line extending direction, and edge
Primary sources line extending direction, each active array switch are also arranged successively, i.e., each active array switch is in array-like arrangement.Base
The active array switch being arranged on plate is grouped, and is divided into different pixel units, one part of pixel unit includes at least one
Active array switch, another part pixel unit are switched including at least two active arrays, wherein are extended along primary sources line
Each pixel unit of direction arrangement is alternately connected to adjacent primary sources line and secondary sources line.
At this point, if the data polarity of primary sources line load is positive in a start-up time, the load of secondary sources line
Data polarity be negative, then the polarity for each column pixel unit being arranged along the extending direction of primary sources line corresponding is in positive polarity
And negative polarity, under the polar data-driven of correspondence, the active array switch in each column pixel unit is loaded onto its corresponding liquid
The deflection voltage of brilliant molecule is at positive polarity or negative polarity.So that each active array that battle array is arranged along primary sources line extending direction

Dynamic array switch quantity is equal, and one of pixel unit in adjacent two pixel units on the direction that scan line extends
Each active array switch connection primary sources line, each active array switch connection he second-class number in one other pixel unit
According to line.
Two pixel units adjacent along the extending direction of scan line are separately connected primary sources line and secondary sources
Line so that along scanning line direction it is adjacent each pixel unit load data polarity on the contrary, and display polarity it is opposite.For example, such as
Pixel unit P1 and pixel unit P2 in Fig. 1, if primary sources line D1 ' load is connected thereto in a start-up time
The data polarity of pixel unit P1 be positive, secondary sources line D2 ' is loaded to the data pole of pixel unit P2 connected to it
Property be negative, then the active array switch in P1 and P2 shows polarity on the contrary, improving the display under big visual angle in this start-up time
Effect.And the polar data-signal of different data is loaded using adjacent two data line, it can be improved anti-in data load process
Interference improves display image quality and exhibit stabilization.

The active array switch of primary sources line connection in right adjacent data line, " 2 " indicate two radicals adjacent with its left and right
According to the active array switch of the secondary sources line connection in line.If in a start-up time, primary sources line D1 ', D3 ',
D5 ', D7 ', D9 ', D11 ' load data polarity be "+", and corresponding neighbour secondary sources line D2 ', D4 ', D6 ',
The data polarity that D8 ', D10 ', D12 ' are loaded is "-", then the display polar alignment of the corresponding pixel region of each data line is then as schemed
Shown in 6.Similarly, in next start-up time, after each data line carries out polarity reversion, each corresponding pixel region of data line is shown
Show that polar alignment becomes shown in Fig. 7.
The active array in the pixel unit on the extending direction of primary sources line is opened in one of the embodiments,
The quantity of pass is successively according to 1,4,4,1 circulation.Using this pixel unit set-up mode, can under column inversion driving method,
Realize that this opposite pixel of 1+4 as shown in Figure 6 and Figure 7 shows that polarity is carried mode and shown.
