Embodiment, belong to the scope of protection of the invention.
Below in conjunction with the accompanying drawings, the driving compensation method of display panel of the present invention is illustrated.
As shown in figure 1, it is the layout and connection of the partial pixel unit of display panel 10 in one embodiment of the invention
Schematic diagram.Wherein, for convenience of description, Fig. 1 only shows the layout and connection schematic diagram of partial pixel unit.
Specifically, X mutually insulateds spaced apart are set up in parallel a plurality of data lines Di~Dj along a first direction；It is more
Bar scans Gx~Gy being set up in parallel along second direction Y mutually insulateds spaced apart.Wherein, first direction X and second
Direction Y is mutually perpendicular to, 1≤i<J, 1≤x<Y, i, j, x and y are natural number.A plurality of data lines Di~Dj and multi-strip scanning line
Gx~Gy forms the region of matrix arrangement, and pixel cell Px is located in the region of foregoing matrix arrangement, and respectively with corresponding number
It is electrically connected with according to line and multi-strip scanning line.Wherein, the first direction X and second direction Y is mutually perpendicular to, and first direction X is same
When also illustrate that line direction, second direction Y represents column direction.
Data drive circuit 12 is arranged at one end of a plurality of data lines Di~Dj, wherein, data drive circuit 12 wraps
Multiple data output end Pi are included, each of which data output end Pi correspondingly connects a data line Di, for for corresponding number
According to line Di outputting data signals.
Accordingly, scan drive circuit (not shown) is arranged at described multi-strip scanning line Gx~Gy one end, wherein, scanning is driven
Dynamic circuit includes multiple scanning output ends, and each of which data output end correspondingly connects a scan line Gx, for for correspondingly
Data wire Gx, export scanning signal.
When foregoing display panel 10 carries out image display, scan drive circuit is followed successively by scan line along second direction Y
Gx, Gx+1......, Gy provide scanning signal, that is to say and are scanned successively according to row；Meanwhile when scan drive circuit is wherein one
When bar scan line Gx provides scanning signal, data drive circuit 12 provides pending image for Di, Di+1......, Dj simultaneously and shown
The data-signal shown.Thus, data wire cooperates picture signal loading and pixel electrode Px, pixel electrode Px with scan line
Common electric voltage is coordinated to produce the anglec of rotation corresponding to the generation of electric field driven liquid crystal molecule, and then the display of picture signal.
Referring to Fig. 2, it is the equivalent circuit that any one data line Di is connected with multiple pixel cell Px in a row
Figure.
Incorporated by reference to shown in Fig. 1-2, further investigate and find by inventor, because each number line Di connections are positioned at a row
Multiple pixel cell Px, that is to say data wire Di and meanwhile connection positioned at i-th row multiple pixel cell Px.Data wire Di and one
Multiple pixel cell Px connections in row can be equivalent to the resistance-capacitance (Resistor-Capacitor of multiple series connection
Circuit, abbreviation RC circuit), it is specific as shown in Figure 3.Fig. 3 be two as shown in Figure 1 apart from the data output circuit 12 not
The oscillogram of the same data-signal received with same data line Di pixel cell Px.Wherein, the dotted line in Fig. 3 is number
It is believed that the original waveform that number Sdi exports from the output end of data drive circuit 12, solid line is data-signal Sdi in data line transfer mistake
Distorted waveform in journey.
As shown in figure 3, with range data drive circuit 12 data output end 121 it is more remote, data-signal Sdi by
The influence of RC circuits is bigger.Data-signal Sdi by more rank RC circuits due to being influenceed and ideal waveform (data-driven electricity
The data-signal Sdi of the data output end Pi of road 12 outputs) gap is bigger, and it that is to say and prolong in data-signal Sdi transmitting procedures
Slow distortion and the output end of data drive circuit 12 are more remote more serious.Thus, inventor is found that display picture is uneven, shows and lose
Very, the reason for causing display effect poor.
