Description
Technical field
The present invention relates to display technology field more particularly to a kind of display panel and its test method, application methods.
Background technology
Due to the ease for use of touch screen, the multifunctionality of operation and the price constantly declined and the yield steadily improved,
They are just becoming more and more universal.Touch screen according to position cocoa of its setting be divided into external hanging type with it is embedded, external hanging type can be with
Panel with touch function is located in front of display, touch-surface covers the visible area of display area, realizes touch-control.
It is embedded, touch function is integrated on panel, protective glass is sticked in outside, and user touches screen by finger, you can realize
Operation.
In order to further decrease the complexity of manufacture craft and the thickness of display panel, a kind of incite somebody to action is proposed in the prior art
Public electrode is multiplexed with the display panel of touch control electrode.Fig. 1 is the schematic diagram of touch control electrode in display panel in the prior art.
As shown in Figure 1, the self-tolerant touch control electrode (1 ' and 2 ') for including multiple matrix arrangements for display panel in the prior art.Each
Independent touch control electrode is formed by ITO common electrodes, is drawn out to outside array each by independent output busbar, is connected to respectively
Independent preamplifier 3 ', the touch-control stage of usual display panel and display stage time-sharing operation.In display, driving circuit
Apply common voltage in self-tolerant touch control electrode to be allowed to use as public electrode；In touch control detection, driving circuit is certainly
Apply touch control detection signal in appearance formula touch control electrode, to realize to touch control detection.
Fig. 2 be display panel in the prior art in touch control electrode test phase module connection figure.As shown in Fig. 2,
In the manufacturing process of display panel there is a VT to test (Visual Test, the visual testing) stage.In VT tests usually
Public electrode can be divided into the first common electrode group and the second common electrode group (or more multigroup), the first common electrode group includes
Multiple first self-tolerant touch control electrodes 1 ', the first self-tolerant of each of first common electrode group touch control electrode 1 ' pass through one respectively
Switching device 4 ' is connected to first input end 51 '.Second common electrode group includes multiple second self-tolerant touch control electrodes 2 ', and second
The second self-tolerant of each of common electrode group touch control electrode 2 ' is connected to the second input by a first switch device 4 ' respectively
End 52 '.When test, by inputting the signal of different voltages to first input end 51 ' and the second input terminal 52 ', to make display surface
Plate generate the horizontal stripe pattern at light and shade interval judge circuit break-make situation (can also light and shade interval chessboard grid pattern or
The nicking pattern at light and shade interval).The control terminal of all switching devices 4 ' is connected respectively to a switch master control end 53 '.Derailing switch
Part 4 ' may include an at least thin film transistor (TFT) (TFT), and but not limited to this.First input end 51 ', the second input terminal 52 ' with
And switch master control end 53 ' all in be integrated in a testing weld pad 5 '.
