Electricity or when putting, detects in the display panel multiplex switch pipe in often row pixel with the presence or absence of abnormal in advance.Detect often capable picture
Each self-corresponding multiplex switch pipe of element whether there is situation about not completely closing.Specifically, can be just pre- when dispatching from the factory
First multiplex switch pipe all in the display panel is detected, and testing result can be further stored in driving chip
In, when plate carries out discharge and recharge over there, the service condition of the multiplex switch pipe of often row pixel in panel is directly read, if existing different
Reason condition, then only need in discharge and recharge, and change data drive circuit has the charging of abnormal pixel to its multiplex switch pipe
Mode.Wherein, the abnormal conditions of multiplex switch pipe are not limited solely to the situation that multiplex switch Guan Wei is completely closed, or
Multiplex switch pipe is damaged or can not closed, and the present invention is not specifically limited.
And detection structure specifically divides three kinds of situations：
A) detect whether the corresponding first multiplex switch pipe of all first pixels completely closes in the row；
B) detect whether the corresponding second multiplex switch pipe of all second pixels completely closes in the row；
C) detect whether the corresponding 3rd multiplex switch pipe of all 3rd pixels completely closes in the row.
S110, all pixels for be controlled by current horizontal scanning line to current horizontal scanning line output scanning drive signal
Scanning switch pipe is opened.
If reading in current line pixel, there is multiplex switch pipe to occur abnormal.Charge and discharge subsequently is being carried out to the display panel
In electric process, when scanning signal CK is high level, the scanning switch pipe for all pixels that the current horizontal scanning line of control is controlled
Open, i.e. the 3rd switching tube of the first switch pipe of the first pixel, the second switch pipe of the second pixel and the 3rd pixel respectively by
Open.
S120, exports demultiplex control signal to open multiplex switch pipe, Mei Gefu to the control end of multiplex switch pipe successively
Current data line charges to the pixel electrode in its corresponding pixel during being opened with switching tube.
When being charged to the first pixel, the first multiplexed signals (the is inputted by the control end of the first multiplex switch pipe
One multiplexed signals is high level), the first multiplex switch pipe is opened, during the first multiplex switch pipe is opened, current data line pair
First pixel electrode charges to the first charging voltage level X.
After the first pixel electrode charging complete, the first multiplex switch pipe is closed.Then to the second pixel of the second pixel
Electrode is charged, and inputting the second multiplexed signals by the control end of the second multiplex switch pipe, (the second multiplexed signals is high electricity
It is flat), the second multiplex switch pipe is opened, during the second multiplex switch pipe is opened, current data line charges to the second pixel electrode
Electricity is to the second charging voltage level Y.
After the second pixel electrode charging complete, the second multiplex switch pipe is closed.To the 3rd pixel electrode of the 3rd pixel
Charged, the 3rd multiplexed signals (the 3rd multiplexed signals is high level) is inputted by the control end of the 3rd multiplex switch pipe, beaten
The 3rd multiplex switch pipe is opened, during the 3rd multiplex switch pipe is opened, current data line charges to the 3rd to the 3rd pixel electrode
Charging voltage level Z.After the 3rd pixel electrode charging complete, the 3rd multiplex switch pipe is closed.
S130, stops output demultiplex control signal, and the voltage for adjusting current data line is corresponding to abnormal multiplex switch pipe
The charging voltage level of pixel.
Because the multiplex switch pipe of pixel has that exception is divided into three kinds：
A) the first multiplex switch pipe of the first pixel exists abnormal.
During being charged to the second pixel and the 3rd pixel, the first pixel electrode because the first multiplex switch pipe without
Method disconnects with data wire completely easily there is the phenomenon leaked electricity, and if the first pixel the first charging voltage X levels less than second,
Charging voltage level Y, Z of 3rd pixel, is also easy to cause the first pixel electrode of the first pixel to be charged by mistake, causes panel to show
Show that picture is abnormal.Therefore to the row all pixels charging complete after, stop export the row in all pixels demultiplex control signal
Afterwards, stop to current horizontal scanning line output scanning drive signal before, (i.e. scanning signal line blanking period (HB,
HBlank)), the first charging of the voltage Vdata of adjustment current data line to corresponding first pixel of the first multiplex switch pipe is electric
Level X is pressed, make it that the voltage of the first pixel electrode is maintained at the first charging voltage level X.

Easily there is the phenomenon leaked electricity, and if the second pixel the second charging voltage Y levels be less than the 3rd pixel charging voltage level Z,
It is also easy to cause the second pixel electrode of the second pixel to be charged by mistake, causes Display panel picture abnormal.Therefore to all pictures of the row
After plain charging complete, stop export the row in all pixels demultiplex control signal after, stop defeated to current horizontal scanning line
Go out before scanning drive signal, (i.e. the line blanking period (HB, HBlank) of scanning signal), adjust the voltage of current data line
Vdata to corresponding second pixel of the second multiplex switch pipe the second charging voltage level Y, to cause the electricity of the second pixel electrode
Pressure is maintained at the second charging voltage level Y.
C) the 3rd multiplex switch pipe of the 3rd pixel exists abnormal.
After the row all pixels charging complete, stop exporting the demultiplex control signal of all pixels in the row.Stopping
Export after demultiplex control signal, stop to before current horizontal scanning line output scanning drive signal, (the i.e. horizontal blanking of scanning signal
Period (HB, HBlank)), adjust the voltage Vdata to the of corresponding 3rd pixel of the 3rd multiplex switch pipe of current data line
Three charging voltage level Z, make it that the voltage of the 3rd pixel electrode is maintained at the 3rd charging voltage level Z.
Wherein, the first charging voltage level X, the second charging voltage level Y and the 3rd charging voltage level Z are respectively first
Charging potential when pixel, the second pixel and the 3rd pixel are normally shown.
If in addition, the multiplex switch pipe of pixel does not have occur being somebody's turn to do for abnormal conditions during advance detection in the display panel
Method is also suitable, i.e. the line blanking period in scanning signal, adjusts the voltage Vdata to first, second or the of current data line
The charging voltage level of corresponding first, second or third pixel of three multiplex switch pipes, can prevent or avoid the pixel in advance
Corresponding multiplex switch pipe occurs abnormal and causes wrong situation about charging.
S140, stops exporting scanning drive signal to current horizontal scanning line.
When scanning drive signal CK is low level, all pixels keep respective charging voltage level in current line, directly
It is again turned on to respective scanning switch pipe.
The discharge process of above-mentioned pixel is similar, and here is omitted.
In above-mentioned embodiment, by after output demultiplex control signal is stopped, stopping sweeping to the output of current horizontal scanning line
Retouch before drive signal, dynamic change data line can improve a certain multiplexing in current line to the charging/discharging voltage level of pixel
Switching tube can not completely close the problem of causing respective pixel mistake discharge and recharge, lift the display of image quality.
