In the development of panel narrow frame.
Specifically, please referring to Fig. 3, Fig. 4 and Fig. 5, Fig. 3 is the amplification simplification figure in the region C of Fig. 1, and Fig. 4 is the prior art
Same a line sub-pixel use the corresponding timing diagram of driving method, Fig. 5 is the operation principle schematic diagram of Fig. 4, by Fig. 4 and Fig. 5
It is found that the first scan line G1 and second being electrically connected with same a line sub-pixel is swept in this frame time that the prior art uses
Retouch the overlapping driving method of the scanning signal of line G2, wherein the first scan line G11 and the first row sub-pixel of the first row sub-pixel
The second scan line G12 successively open the first sub- picture to be electrically connected in the same column repetitive unit 10 with same data line S
Element 1001 and the second sub-pixel 1002 charge, and the first sub-pixel 1001 scans letter in the first scan line G11 of the first row sub-pixel
Number failing edge complete charging after, the data of the first sub-pixel 1001 are refreshed, and (the first sub-pixel 1001 may be bright at this time
State is also likely to be dark state), and the first row sub-pixel at this time the first scan line G11 it is already off do not charge, then
Second sub-pixel 1002 is after the failing edge of the second scan line G12 scanning signal of the first row sub-pixel completes charging, the second son
The data of pixel 1002 are refreshed (it is also likely to be dark state that the first sub-pixel 1001, which may be bright state, at this time), but this
When the first sub-pixel 1001 by the first row sub-pixel second scan line G12 scanning signal failing edge (passing through capacitor Cpg1 ') coupling
Conjunction drags down its current potential, therefore in the whole process, and the first sub-pixel 1001 is altogether by the first of itself the first row sub-pixel
Under second scan line G12 scanning signal of scan line G11 scanning signal failing edge (by capacitor Cpg1) and the first row sub-pixel
Drop is along (passing through capacitor Cpg1 ') two secondary couplings, and the second sub-pixel 1002 is only by the second scanning of itself the first row sub-pixel
Line G12 scanning signal failing edge (by capacitor Cpg2) secondary coupling, due to the first sub-pixel 1001 have one by the first row son
The process that the first scan line G11 scanning signal failing edge (passing through capacitor Cpg1 ') coupling of pixel drags down its current potential, therefore
Under identical driving voltage, due to coupling amount difference, lead to the first sub-pixel 1001 and the final pixel of the second sub-pixel 1002
Voltage is different, and the display brightness so as to cause them is different and generates vertical line.
Therefore, the embodiment of the present invention improves above-mentioned vertical line phenomenon by changing the driving method of display panel, specifically,
Incorporated by reference to reference Fig. 2 and Fig. 4, in a frame time of the present embodiment, the first scan line G1 for being electrically connected with same a line sub-pixel and
The scanning signal of second scan line G2 does not overlap, i.e., be electrically connected in the same column repetitive unit 10 with same data line S
The driving time of one sub-pixel 1001 and the second sub-pixel 1002 is staggered completely, and the scanning signal of the second scan line G2 is later than
The scanning signal of scan line G1, so as to so that the first row sub-pixel the first scan line G11 and the first row sub-pixel the
The first sub-pixel that two scan line G12 successively open to be electrically connected in the same column repetitive unit 10 with same data line S
1001 and second sub-pixel 1002 charge, first scan line G11 scanning signal of first sub-pixel 1001 in the first row sub-pixel
Failing edge complete charging after, by the first row sub-pixel the first scan line G11 scanning signal failing edge (by capacitor Cpg1),
The second of second scan line G12 scanning signal rising edge (by capacitor Cpg1') of the first row sub-pixel and the first row sub-pixel
Scan line G12 scanning signal failing edge (by capacitor Cpg1') three secondary coupling, the second sub-pixel 1002 is in the first row sub-pixel
After the failing edge of second scan line G12 scanning signal completes charging, letter only is scanned by the second scan line G12 of the first row sub-pixel
Number failing edge (by a capacitor Cpg2) secondary coupling.Due to the second scan line G12 scanning signal rising edge of the first row sub-pixel
It cancels out each other with failing edge to the coupling of the first sub-pixel 1001, the coupling amount of the first sub-pixel 1001 is only by the first row sub-pixel
The first scan line G11 scanning signal failing edge (by capacitor Cpg1) determine, due to the Cpg1 under identical driving voltage
Equal to Cpg2, so the coupling amount of the first sub-pixel 1001 and the second sub-pixel 1002 can be equal, it is perpendicular so as to improve display
The phenomenon that line.
It should be noted that for the structure of clear signal the present embodiment, Fig. 1 only illustrates the part of display panel 000
The cabling etc. of structure, the other structures and non-display areas NA that do not describe to the present embodiment technical solution is not illustrated, art technology
Personnel carry out related understanding in combination with the basic structure of display panel in the prior art.Fig. 2 of the present embodiment is only schematically to draw
The corresponding timing diagram of the driving method of display panel 000 out need to only expire when it is implemented, can be configured according to the actual situation
In one frame time of foot, the scanning signal of the first scan line G1 and the second scan line G2 that are electrically connected with same a line sub-pixel are not handed over
It is folded, and the scanning signal of the second scan line G2 is later than the scanning signal of the first scan line G1.When a frame in the embodiment of the present invention
Between refer to scan line drive circuit complete once to all scan line G provide driving scanning signal needed for the time.

Display panel of the invention is the display panel of double-gate structure, by odd in first scanning line traffic control row sub-pixel
The unlatching of ordered series of numbers sub-pixel passes through the unlatching of even column sub-pixel in second scanning line traffic control row sub-pixel；One data line
For data voltage signal to be written to two column sub-pixels adjacent with the data line in column repetitive unit, each scan line passes through
Scan line drive circuit provides driving scanning signal for scan line, and pieces of data line provides data by driving chip for data line
Voltage signal, for the display panel compared to single grid structure, the quantity of the display panel of this kind of double-gate structure, data line is basic
On can reduce half, so that the cost for connecting the driving chip of data line is also accordingly reduced, therefore can be in save the cost
The frame that display panel can also be reduced simultaneously, is conducive to the development of panel narrow frame.The drive of present invention setting display panel
Dynamic method is in a frame time, and the scanning signal of the first scan line and the second scan line that are electrically connected with same a line sub-pixel is not handed over
It is folded, even if the driving time of the two sub-pixels in the adjacent column being electrically connected in the same column repetitive unit with same data line
It is staggered completely, and the scanning signal of the second scan line is later than the scanning signal of the first scan line, so as to so that in adjacent column
The phenomenon that coupling amount of two sub-pixels is equal, improves display vertical line, promotes display quality.
Although some specific embodiments of the invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to being illustrated, the range being not intended to be limiting of the invention.The skill of this field
Art personnel are it should be understood that can without departing from the scope and spirit of the present invention modify to above embodiments.This hair
