It (is not shown in Fig. 3) including pixel.In the first sub- viewing area 211, the second sub- viewing area 212, the sub- viewing area 213 and the 4th of third
When pixel in sub- viewing area 214 is shown, the first scan line 271 transmits scanning signal line by line, and the first data line 261 transmits by column
Data-signal is for driving pixel to show.There is no pixel at the display panel 20 of 24 position of through hole, therefore is penetrating through
At the corresponding display panel 20 in hole 24, the first scan line 271 transmits scanning signal, and the first data line 261 transmits data-signal
The task that the first data line 261 does not charge to pixel in time, corresponding period in this stage can be at the first time
Section.And the first data line 261 is electrically connected with discharge cell 25, therefore can in first time period by discharge cell 25 to the
One data line 261 discharges, to guarantee the narrow side on 24 periphery of through hole without additional addition device on 24 periphery of through hole
On the basis of frame, so that the available release of electrostatic on 24 periphery of through hole, improves the antistatic property on 24 periphery of through hole, prevent

It should be noted that first time period is divided into multiple sub- periods, different first scan lines 271 are corresponding at least
One the first data line 261 corresponding sub- period.First time period is illustrated illustratively with unilateral driving and Fig. 3 below
Discharge process of the interior discharge cell 25 to the first data line 261.
In Fig. 3, display panel successively includes first the first scan line 271 and the first scan line of Article 2 in X direction
271, it successively include first the first data line 261 and the first data line of Article 2 261 along Y-direction.First the first scan line
271 transmission scanning signals, first the first data line 261 and the first data line of Article 2 261 transmit data-signal corresponding first
A sub- period in period, the first scan line of Article 2 271 transmit scanning signal, first 261 He of the first data line
The first data line of Article 2 261 transmits data-signal and corresponds to another sub- period in first time period.
Fig. 4 is a kind of timing diagram for the display panel that Fig. 3 is provided.As shown in figure 4, scan1 is first first in X direction
The timing of scan line 271, Vdata21 are the timing along first the second data line 262 of Y-direction, and Vdata11 is along Y-direction the
The timing of one the first data line 261, Vdata12 are the timing along the first data line of Y-direction Article 2 261, and Vdata2n is edge
The timing of the second data line of Y-direction the last item 262.
In the first stage before T1, in X direction before first the second scan line, 272 to the first the first scan lines 271
The second scan line 272 transmit scanning signal, data line 26 (including the first data line 261 and second data line 262) successively passes
The pixel of transmission of data signal driving display panel is shown.
In the first stage when T1, scan1 is low level, and first the first scan line 271 transmits scanning signal, display panel
Interior first the second data line 262 to the second data line of the last item 262 along Y-direction successively transmits data-signal, to first
The corresponding row pixel of the first scan line of item 271 carries out driving display one by one.Scanning signal is transmitted in first the first scan line 271
During, the stage of the second data line 262 transmission data-signal (schematically illustrates the first of first stage T1 in Fig. 4
Sub-stage t11 and the 4th sub-stage t14) it is the mistake that the pixel in driving display panel in the corresponding viewing area of through hole 24 is shown
Journey.And the stage of the first data line 261 transmission data-signal (schematically illustrates the second sub- rank of first stage T1 in Fig. 4
Section t12 and third sub-stage t13) it does not need to charge to pixel, therefore the second sub-stage t12 and third of first stage T1
One sub- period of sub-stage t13 composition first time period.The the second sub-stage t12 and third sub-stage of T1 in the first stage
When t13, two the first data lines 261 are discharged by discharge cell 25, so that the charge on two the first data lines 261 discharges,
So that the available release of electrostatic on 24 periphery of through hole, improves the antistatic property on 24 periphery of through hole, prevents from penetrating through
Because electrostatic damages at hole 24.
When the first scan line of Article 2 271 transmits scanning signal, a corresponding second stage (being not shown in Fig. 4).?
Second stage, it is identical as first stage T1, along first article of second data line 262 of Y-direction to the last item the in display panel
Two data lines 262 successively transmit data-signal, and it is aobvious to carry out driving one by one to the corresponding row pixel of the first scan line of Article 2 271
Show.The stage of second data line 262 transmission data-signal is the picture driven in display panel in the corresponding viewing area of through hole 24
The process of element display.And the stage of the first data line 261 transmission data-signal does not need to charge to pixel, therefore can be with structure
At another sub- period of first time period.In the stage of the first data line 261 transmission data-signal, two the first data lines
261 are discharged by discharge cell 25, so that the available release of electrostatic on 24 periphery of through hole, improves 24 periphery of through hole
Antistatic property prevents at through hole 24 because electrostatic damages.
When being discharged by discharge cell 25 the first data line 261 in first time period, degree of discharge and first
The discharge line formed in the discharge time of period and 25 discharge process of discharge cell is related.Because the first data line 261 passes through
Discharge cell 25 discharges, therefore every first data line 261 can form a discharge line.That is degree of discharge and first
The time of period is related to the number of the first data line 261.Discharge time is longer, and the number of the first data line 261 is more, puts
Electric degree is bigger, and the antistatic property resulting improvement on 24 periphery of through hole is bigger.
The discharge time of first time period and driving frequency, the number and the first data line of the first scan line 271 of pixel
261 number is related.The driving frequency of pixel is bigger, and the driving time of every row pixel is shorter, and corresponding first scan line 271 passes
The time of defeated scanning signal driving one-row pixels is shorter, therefore the driving time of each pixel is shorter, i.e. first time period
Each of interior sub- period shortens, and discharge time is shorter, and degree of discharge is smaller.Illustratively, each of first stage T1 in Fig. 4
The time of sub-stage (such as the first sub-stage t11, the second sub-stage t12, third sub-stage t13 and the 4th sub-stage t14) becomes
It is short, the sub- time of the first time period that the second sub-stage t12 and third sub-stage t13 of corresponding first stage T1 is constituted
The time of section shortens, therefore discharge time shortens, and degree of discharge becomes smaller.Opposite, the driving frequency of pixel is smaller, discharge time
Longer, degree of discharge is bigger.And the number of the first scan line 271 determines the number of the sub- period in first time period.Cause
The number of this first scan line 271 is more, and the number of the sub- period in first time period is more, and the time of first time period gets over
Long, discharge time is longer, and degree of discharge is bigger.The number of first scan line 271 is fewer, the sub- period in first time period
Number is fewer, and the time of first time period is shorter, and discharge time is shorter, and degree of discharge is smaller.In addition, when the first data line 261
Number it is more, the sub-stage of the sub- period of composition first time period is more in first stage T1, corresponding first time period
The sub- period time it is longer, discharge time is longer, and degree of discharge is bigger.Opposite, the number of the first data line 261 is got over
Few, the sub-stage of the sub- period of composition first time period is fewer in first stage T1, and discharge time is shorter, and degree of discharge is got over
It is small.Illustratively, after the size of through hole 24 is fixed, the number of the first scan line 271 has 100, every first scan line
The 271 sub- periods for including were 8 μ s, then display panel passes through the time that the first data line 261 discharges for 800 μ s, such as in a frame
Fruit driving frequency is 60Hz, then display panel electric discharge per second 60 times, can effectively discharge the electrostatic on 24 periphery of through hole at this time, from
And the antistatic property on 24 periphery of through hole is improved, it prevents at through hole 24 because electrostatic damages.
In addition, the number of the first data line 261 determines the number of the discharge line formed in discharge process.First data
The number of line 261 is more, and discharge line is more, and the degree of discharge in the same time is bigger.Opposite, the first data line 261
Number is fewer, and discharge line is fewer, and the degree of discharge in the same time is smaller.
The route product of degree of discharge and discharge time and electric discharge is positively correlated, therefore, after the size of through hole 24 determines,
The number of first scan line 271 and the first data line 261 through reasonable settings, so that degree of discharge reaches maximum.It is exemplary
Ground, Fig. 5 are a kind of wire structures schematic diagram of first data line and the first scan line provided in an embodiment of the present invention.Such as Fig. 5 institute
Show and (the second non-display area 23 be not shown in Fig. 5), in X direction first the first scan line 271 and the last item scan line 271 with
And along the first area that first the first data line 261 of Y-direction and the first data line of the last item 261 form in through hole 24
215 be a square, and the square of the formation of first area 215 is the inscribed square of through hole 24.
