60 grid is electrically connected, and optionally, the grid of 2 numbers switch 60 in number switching group 60A1 is electrically connected with the 3rd control signal wire 61
Connect.3rd control signal wire 61 is used for transmission the 3rd control signal, to control leading for 2 numbers switch 60 in number switching group 60A1
Logical or cut-off.
The grid of 2 numbers switch 60 in number switching group 60A2 is electrically connected, optionally, 2 numbers in number switching group 60A2
The grid of switch 60 is electrically connected with the 4th control signal wire 62.4th control signal wire 62 is used for transmission the 4th control signal, with
Control the on or off of 2 numbers switch 60 in number switching group 60A2.
In the present embodiment, without control signal is provided separately for every number switch 60, by the e in a number switching group 60A
The grid of number switch 60 is electrically connected, and is the e number switch 60 that can control in a number switching group 60A using a control signal
On or off, the quantity of control signal can be saved, simplify the design of display panel.
In some optional embodiments, incorporated by reference to reference to figure 8 and Fig. 9, pixel 21 includes pixel switch 31 and pixel electricity
Pole 30, pixel switch 31 are corresponded with pixel electrode 30 and set；The grid of pixel switch 31 is electrically connected with gate line 10, pixel
First pole of switch 31 is electrically connected with data cable 20, and the second pole of pixel switch 31 is electrically connected with pixel electrode 30.
In m*n sub- viewing areas 40, the sub- viewing area 40 beyond sub- viewing area 40A is updated to keep sub- viewing area 40B.Figure
In 9, illustrated so that region P2 is renewal image district as an example.In the display stage, signal processing unit by xth two field picture and xth+
1 two field picture is compared, and the (x+1)th two field picture region different with xth two field picture is renewal image district P2, and renewal image district P2 is
To need refreshing pixels 21, to show the region of new image.Sub- viewing area 40 where updating image district P2 is aobvious for renewal
Show area 40A.In first substrate shown in Fig. 9, the quantity for updating sub- viewing area 40A is one.
In addition to sub- viewing area 40A is updated, remaining sub- viewing area 40 is the sub- viewing area 40B of holding.In other words, keep son aobvious
Show that area 40B need not show new image, therefore keep the pixel 21 in sub- viewing area 40B without refreshing.In Fig. 9, son is kept
The quantity of viewing area 40B is three.
Keep sub- viewing area 40B to include first and keep sub- viewing area 40B1 and remaining second sub- viewing area 40B2 of holding.
Wherein, first keep sub- viewing area 40B1 and update sub- viewing area 40A common gates polar curve group 10A, be, first keeps son display
Pixel 21 in area 40B1 shares same grid line groups 10A with updating the pixel 21 in sub- viewing area 40A.Due to gate line 10
After receiving signal, a gate line 10 transmits signal, even if first keeps sub- viewing area 40B1 to refresh picture
Element 21, first keeps the gate line in the grid line groups 10A that the pixel 21 in sub- viewing area 40B1 is electrically connected also to receive grid
Pole signal.
In addition to first keeps sub- viewing area 40B1, remaining keeps sub- viewing area to keep sub- viewing area 40B2 for second.Fig. 9
In, the quantity of the second sub- viewing area 40B2 of holding is two, is respectively that the sub- viewing area 40B21 and second of the second holding keeps sub aobvious
Show area 40B22.Since the second sub- viewing area 40B2 of holding is without refreshing pixels 21 and the second sub- viewing area 40B2 of holding and renewal
Sub- viewing area 40A not common gate polar curve group 10A, the gate line 10 that the pixel 21 in sub- viewing area 40B2 is electrically connected is kept with second
Signal need not be received.
In the present embodiment, the first electricity is received with the second gate line 10 for keeping the pixel 21 in sub- viewing area 40B2 to be electrically connected
Signal is pressed, first voltage signal is used to control pixel switch 31 to end.Gate line 10 in grid line groups 10A2 is without receiving grid
Pole signal, is in order to further ensure the gate line 10 in grid line groups 10A2 can control the pixel switch 31 being connected electrically
Cut-off state, the gate line 10 into grid line groups 10A2 transmit first voltage signal, and first voltage signal can control and grid
The pixel switch 31 that gate line 10 in polar curve group 10A2 is electrically connected ends.
In the present embodiment, the pixel 21 updated in sub- viewing area 40A needs to refresh, the gate line 10 in grid line groups 10A1
Signal is received, and the data cable 20 in data line group 20A1 receives data-signal.Due to the data in data line group 20A1
Line 20 has also extended past one second and has kept sub- viewing area 40B21, second keeps the picture in sub- viewing area 40B21 in order to prevent
Element 21 receives data-signal, and the gate line 10 into grid line groups 10A2 transmits first voltage signal, with control and gate line
The pixel switch 31 that gate line 10 in group 10A2 is electrically connected ends, and further prevents in the sub- viewing area 40B21 of the second holding
Pixel 21 will not receive data-signal.
It should be noted that in order to clearly illustrate the technical solution of the present embodiment, Fig. 9 illustrates the first of Fig. 8 offers
The structure of the simplification of substrate, the structures such as gate line 10, data cable 20, pixel 21 are eliminated in Fig. 9, and Fig. 9 only illustrates Fig. 8 offers
First substrate in the structure such as viewing area AA, non-display area BB, gate line area 10B, data cable area 20B and sub- viewing area 40.
In Fig. 9, only illustrated so that pixel 31 is N-type TFT switch as an example, optionally, pixel switch 31 is N
Type thin film transistor switch.Alternatively, optional, pixel switch 31 switchs for P-type TFT.
