First to fourth signal lines are electrically connected testing weld pad 117-125 (the 4th inspections for being located at non-display area
The testing weld pad for surveying signal wire electrical connection is not drawn into).
It should be noted that the first non-display area 127 or the 3rd non-display area 112 are provided with first and are fanned out to cabling and first
Drive pad.Assuming that the first non-display area 127, which is provided with first, is fanned out to cabling and the first driving pad, every first is fanned out to cabling
One end be electrically connected with scan line, the other end be electrically connected with the first driving pad, and the first driving pad is for binding for providing
The integrated circuit of scanning signal, such as scanning drive chip, after integrated circuit binding, the pin of integrated circuit and the first driving weldering
Disk corresponds electrical connection.Integrated circuit is bound to after display panel, when display panel works normally, to scan line 113
Scanning signal is provided.First detection signal line 115 can be fanned out to cabling by first and is electrically connected with corresponding scan line 113.Below
By taking the display panel shown in Figure 1A as an example, illustrate the test process for the display panel that the utility model embodiment provides.In this reality
It applies in example, is carrying out display test phase to display panel, it is non-with the first non-display area 127 and second in the case of proper testing
Viewing area 128 detect image quality and terminal end it is abnormal (for example, open circuit occurs for the first connection for being fanned out to cabling and the first driving pad,
Open circuit has occurred between scan line 113 and integrated circuit).Specifically, the test probe of test equipment can be crimped onto test
On pad 117-122, by testing shorting pin loaded control signal to testing weld pad 119 and testing weld pad 122 so that multiple first
Switch module 116 and multiple second switch modules 130 turn on.By testing shorting pin loaded scanning signal to 117 He of testing weld pad
Testing weld pad 118, loading data-signal to testing weld pad 120 and testing weld pad 121.Scanning signal and data-signal transmit respectively
Onto the scan line 113 and data cable 114 in viewing area 111.Pixel on driving display panel is shown, according to display
Picture determines whether display panel is abnormal, i.e., image quality is detected.And it can detect the first of the first non-display area 127
It is fanned out to whether cabling open circuit occurs, that is, detects terminal end exception.
First non-display area 127 set first be fanned out to cabling and first driving pad, then 127 cabling of the first non-display area and
Device is relatively more, and the size of the first switch module 116 of the first non-display area 127 will not be made big, pass through first switch mould
Block 116 and first detection signal line 115 to scan line 113 scanning signal is provided when, may will cause driving to scan line 113
Scarce capacity and occur picture exception.And the 3rd non-display area 112 has larger space, at this point, the 3rd non-display area 112
The size of 3rd switch module 132 can meet the needs of test, can pass through the 3rd switch module 132 and the 3rd signal lines
131 load scanning signal to scan line 113, realize the detection to display panel.It specifically, can be by the test probe of test equipment
It is crimped onto on testing weld pad 119-125, by testing shorting pin loaded test signal to testing weld pad 119, testing weld pad 122 and surveying
Test weld disk 123 so that multiple second switch modules 130 and multiple 3rd switch modules 132 turn on, and cause multiple first switches
Module 116 turns off.By testing shorting pin loaded scanning signal to testing weld pad 124 and testing weld pad 125, loading data-signal is extremely
Testing weld pad 120 and testing weld pad 121.Scanning signal and data-signal are respectively transmitted to 113 He of scan line in viewing area 111
On data cable 114.Pixel on driving display panel is shown, determines whether display panel is abnormal according to the image quality of display.
If first is fanned out to cabling and first pad is driven to be arranged at the 3rd non-display area 112, it can be by being opened to the 3rd
The testing weld pad loading scanning signal of 132 and the 3rd signal lines 131 of module electrical connection is closed, detection shows whether picture is different
Often, the abnormal conditions of terminal end can be detected and.When the driving force deficiency to scan line 113 occur picture exception, can
Scanning signal, detection display are loaded by the testing weld pad being electrically connected to first switch module 116 and first detection signal line 115
Image quality, determine whether picture abnormal.
Display panel shown in corresponding diagram 1B and 1C, can be by corresponding testing weld pad respectively to the second non-display area
128 the second test signal line 129 and the 4th test signal line 135 loading data-signal 114 of the 4th non-display area 126, come
Whether abnormal and image quality the detection in detection terminal end.The principle of detection and to the first non-display area 127 and the 3rd non-display area
112 detection is similar, repeats no more.
It should be noted that when the control conducting of first switch module 116, it is necessary to which the 3rd switch module 132 is controlled to turn off；
, it is necessary to which first switch module 116 is controlled to turn off when controlling the conducting of the 3rd switch module 132.When control second switch module 130 is led
, it is necessary to which the 4th switch module 136 is controlled to turn off when logical；When control the 4th switch module 136 conducting, it is necessary to control second switch
Module 130 turns off.
The display panel of the present embodiment, the first non-display area set first switch module and first detection signal line, the
Two non-display areas are provided with second switch module and the second signal lines；Other 3rd non-display area sets the 3rd switch module
With the 3rd signal lines and/or, the 4th non-display area sets the 4th switch module and the 4th signal lines.It can pass through
Integrated circuit (such as the turntable driving core of setting for being provided with scanning signal is set in the first non-display area and the 3rd non-display area
Piece) a detection image quality and terminal break exception, if causing picture different the driving force deficiency of scan line during detection image quality
Often, can not effectively detect image quality, can by be not provided with integrated circuit another effectively detection image quality.Second can be passed through
One be provided in the integrated circuit of data-signal detection image quality and terminal is set to break in non-display area and the 4th non-display area
It is abnormal, it, can be with if causing picture abnormal to the driving force deficiency of data cable during detection image quality, can not effectively detecting image quality
By another the effective detection image quality for being not provided with integrated circuit.Image quality can not only be detected by realizing, but also can be detected and be swept
Retouch the problem of terminal of line or data cable and integrated circuit disconnects.
Based on the above technical solutions, the number of 115 and the 3rd signal lines 131 of first detection signal line is preferred
It can be 3.As shown in Figure 1A：
