Embodiment
Fig. 2 is that one of display panel of the present invention maybe embodiment.As shown in the figure, display panel 200 has a viewing area (Active Area; AA) 250, one non-display area and at least one compensating module (as 261～272).The present invention does not limit the kind of display panel 200.In a possibility embodiment, display panel 200 is a liquid crystal display (LCD) panel.
In the present embodiment, signal wire A～D is made up of conductive material, like metal.In addition, the present invention does not limit the kind of signal wire.In a possibility embodiment, signal wire A～D is scan electrode (scan electrode), in order to transmit sweep signal (scan signal).In other possibility embodiment, signal wire A～D possibly be data electrode (data electrode) or common electrode (common electrode), in order to data signal (data signal) or common electric voltage (common voltage).
Zone in the viewing area beyond 250 all is called non-display area.In the present embodiment, non-display area comprises, near-end subarea 210 and anti-terminal region 231～233.Near-end subarea 210 has a plurality of signal wires, is convenient explanation, and Fig. 2 only shows four signal line A～D.
Signal wire A～D is 250 extensions toward the viewing area, in order to the drive signal that one drive circuit provided is sent to the pixel P in the viewing area 250
A1～P
D6In the present embodiment, have drive signal is called the near-end subarea (as 210) of this signal wire by the zone that driver imports the signal wire line segment of viewing area into, and the zone that does not have this type of signal wire line segment is called the anti-terminal region (as 231～233) of this signal wire.
Driving circuit 211 in the near-end subarea 210 is through the signal wire A～D in near-end subarea 210 and the viewing area 250, to pixel P
A1～P
D6Carry out one and discharge and recharge action.In the present embodiment, be with a chip glass joining technique (Chip On Glass; COG) integrate driving circuit 211, give signal wire A～D, in order to pixel P in order to drive signal to be provided
A1～P
A6Discharge and recharge action.In another possibility embodiment, a coil type capable of using engages (Tape Automatic Bonding automatically; TAB) and a chip mantle joining technique (Chip On Film; COF) integrate driving circuit 211, give signal wire A～D in order to drive signal to be provided.
The present invention does not limit the quantity and the kind of driving circuit.In a possibility embodiment, when signal wire A～D was scan electrode, then driving circuit 211 was one scan driver (scan driver), gives pixel P in order to a plurality of sweep signals to be provided
A1～P
D6, make it begin to carry out the charge or discharge action.In another possibility embodiment, when signal wire A～D was data electrode, then driving circuit 211 was a data driver (data driver), gives pixel P in order to a plurality of data-signals to be provided
A1～P
D6, make pixel P
A1～P
D6The interior corresponding electric charge of capacitor stores.
If when importing viewing area (as 250) in order to the signal with driving circuit, then this non-display area is called the near-end subarea of this signal wire to the signal wire line segment (being arranged in the line segment in zone 210 like signal wire A～D) in the non-display area (like zone 210).If non-display area (like zone 231～233) does not comprise the signal wire line segment that drive signal is imported into the viewing area, then be referred to as the anti-terminal region of this signal wire.
For example; Suppose that the one scan driver only provides when giving the viewing area from the right side (like zone 231) of viewing area with sweep signal; Then with scan electrode; The non-display area on right side, viewing area is the near-end subarea of scan electrode, no matter and whether scan electrode is extended into the non-display area (like zone 233) in left side by the viewing area, the non-display area in left side all is the anti-terminal region of scan electrode.Suppose to take with sweep signal the framework that gives the viewing area to be provided by the both sides, viewing area, then the non-display area of both sides is all the near-end subarea of scan electrode.
In like manner; Suppose that a data driver only imports data-signal into viewing area from the upside (like zone 232) of viewing area; And the one scan driver only imports sweep signal into viewing area from the right side (like zone 231) of viewing area; Then the non-display area of display upside is the near-end subarea of data electrode, and is the anti-terminal region of scan electrode.Likewise, the non-display area on display right side is the near-end subarea of scan electrode, and is the anti-terminal region of data electrode.
In the present embodiment, signal wire A～D arranges with the fan-out mode, sends pixel P in order to the signal that driving circuit 211 is provided
A1～P
D6, therefore, the length of signal wire A～D and (line segment length that particularly is positioned at near-end subarea 210 is inequality) inequality.Because the length of signal wire A～D will influence pixel P
A1～P
D6Charging and discharging speed; So speed that discharges and recharges for the pixel on each signal wire of homogenising; Compensating module 261～272 couples corresponding signal wire (like A～D), in order to the different length of compensating signal line A～D, to the influence that action causes that discharges and recharges of pixel.
In the present embodiment, signal wire D does not have compensating module, and compensating module 261～266, signal wire B have compensating module 267～269, signal wire C has compensating module 270～272 and signal wire A has.Because the length of signal wire A～D is different, so, different degree of compensation need be provided to different signal lines.For example, signal wire A is shorter in length than signal wire B, so total degree of compensation of compensating module 261～266 is greater than total degree of compensation of compensating module 267～269.
The present invention does not limit the quantity of the compensating module on each signal wire.In a possibility embodiment, the quantity of compensating module is to depend on the length of signal lines and the compensation ability of compensating module.For example, when the compensation ability homogeneous phase while of each compensating module, then shorter signal wire needs compensating module the more; Or in short signal wire; The bigger compensating module of compensation ability is set, and in long signal wire, the less compensating module of compensation ability is set.
The present invention does not limit the set-up mode of compensating module.In a possibility embodiment, each pixel on the same signal wire all disposes a compensating module.For example, the pixel P-on the signal wire A
A1～P
A6All dispose a compensating module (as 261～266).In another possibility embodiment, maybe be every at a distance from N pixel, just dispose a compensating module, shown in signal wire B and C.At signal wire B is example, whenever just disposes a compensating module at a distance from 1 pixel.In other embodiments, be every at a distance from a fixed range, a compensating module just is set.
In the present embodiment, though the quantity of the compensating module of signal wire B and C identical (all having 3 compensating modules), its compensation ability is also inequality.For example because the length that is shorter in length than signal wire C of signal wire B, so the compensation ability of compensating module 267～269 greater than the compensation ability of compensating module 270～272, can homogenising signal wire B and the influence that different length caused (discharging and recharging speed) of C.
In addition, the compensation ability of the compensating module on the same signal wire maybe be all inequality, all identical or part is identical.In a possibility embodiment, the compensation ability of the compensating module on the same signal wire possibly reduce gradually or increase gradually.In another possibility embodiment, more the compensation ability of the compensating module of approach signal line central authorities is higher.
In the present embodiment, the quantity of the compensating module of signal wire B and C is identical, but is different from the quantity of the compensating module that is couple to signal wire A.In other embodiments, the quantity of the compensating module of unlike signal line maybe all identical, equal difference or a part is identical, and other part is different.As long as suitably adjust the quantity of compensating module and the compensation ability of compensating module, just can compensate the influence that the signal wire A～D of different length is caused.
The present invention does not limit the structure of compensating module 261～272.In the present embodiment, compensating module 261～272 is respectively capacitor C
A1～C
C6In a possibility embodiment, capacitor C
A1～C

A～C
C, the one of which end couples signal wire A～C respectively, and the other end receives a voltage potential V
CMIn a possibility embodiment, voltage potential V
CMIdentical with the current potential of scan electrode in the viewing area 450, but be not in order to restriction the present invention.In other embodiments, voltage potential V
CMThe current potential that is different from scan electrode.
In addition, in the pixel electrode in making viewing area 450 (like the PE of 3D figure), can form a compensating electrode (like the CE of 3D figure
A).Therefore, the formation of compensating electrode can't increase the step of manufacturing.In the present embodiment, the overlapping region of compensating electrode and signal wire A～C has capacitor 461～463.Voltage potential by control compensation electrode and signal wire A～C just can make capacitor C
A～C
CEffect with compensation.
When the insufficient space of viewing area 250, also can compensating module 461～463 be arranged at least one of anti-terminal region 431～433.Moreover, because signal wire A～D does not extend to anti-terminal region 431～433 driving circuits,, can design the bigger capacitor of appearance value so the spendable space of display panel 400 is bigger.
The present invention does not limit the position that is provided with of compensating module.In a possibility embodiment, not only anti-terminal region 432 has compensating module 461～463, connects viewing area 450 and also has compensating module.In addition, if the two ends of a signal wire all extend into non-display area, and when being connected (non-display area that is the signal wire both sides all is the near-end subarea) with driving circuit, the compensating module that then couples this signal wire just only is arranged among the viewing area 450.In other possibility embodiment, except viewing area 450 and anti-terminal region 431～433, compensating module also can be arranged among the near-end subarea 410.
Since compensating module the suitable elasticity in position is set, so can reach higher compensation efficient, the influence that signal wire caused of homogenising different length (charging of pixel and discharge time).In addition, in other embodiments, when compensating module is enough to the problem that signal wire caused of homogenising different length; Then signal wire can adopt schistose texture; And need not adopt snakelike (z shape) structure, thus the shared substrate area of signal wire can be reduced, and the frame of can narrow near- end subarea 210 and 410.
Only if define in addition, all belong to the general understanding of those of ordinary skill in the technical field under the present invention at these all vocabulary (comprising technology and science vocabulary).In addition, only if clear expression, it is consistent that the definition of vocabulary in general dictionary should be interpreted as in the article with its correlative technology field meaning, and should not be construed as perfect condition or too formal voice.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
