It is a kind of schematic flow diagram of the production method of display panel provided in an embodiment of the present invention referring to Fig. 1, as schemed institute
Show, this approach includes the following steps S11~S15:
Step S11: by first substrate and the combination of the second substrate opposite direction to form display base plate, the surface of the second substrate is equipped with
The active switch and pixel unit of array.
Specifically, shown in Figure 3, in display panel manufacture craft, in advance to relatively large first base of two pieces of areas
Plate 110 and the second substrate 120 are processed, then by after processing first substrate 110 and the combination of the second substrate 120 formed it is one piece big
The display base plate 100 of area, the surface of the second substrate 120 are equipped with the active switch and pixel unit of array.In the concrete realization,
The color membrane substrates that first substrate 110 is as opened greatly, the array substrate that the second substrate 120 is as opened greatly, active switch may be, for example,
TFT (thin film transistor (TFT)).Each independent display panel 150 is after carrying out processing cutting by the display base plate 100 of large area
It is manufactured.
Step S12: multiple independent display areas are marked off on display base plate.
Specifically, after forming a biggish display base plate, multiple independent display areas are divided on the display base plate,
Each display area corresponds in subsequent machining technology, the display panel obtained after cutting.
Step S13: at least one opening is cut on the first substrate at each display area edge.
Specifically, ginseng as shown in figure 3 and figure 4, plans the display area of good each display panel on display base plate 100
After 150, an opening 111 is cut in the edge in the display area of display panel 150, and special-shaped display surface one by one is made
Plate, opening 111 are located at the inside of the display area 150 divided.In the specific implementation, opening 111 can open up one, it can also root
Multiple openings 111 are set according to actual needs.The shape of opening 111 may be, for example, rectangle, or semicircle, can be according to reality
It is set.
Step S14: test point is arranged at the opening to detect to display area.
Specifically, display base plate 100 before being cut into independent display panel one by one will to it is all will cut it is aobvious
Show that region 150 is tested, to detect the performance of each display panel.The embodiment of the present invention will test the survey of display panel performance
Pilot 200 is arranged at above-mentioned opening 111, then the performance of display panel is detected by test point 200.The performance that need to be detected can
Whether cabling is intact for example, inside display panel, shows in the process with the presence or absence of point defect, spot defect etc..
Step S15: after detection, display base plate is carried out to be cut to multiple display panels.
Specifically, it will test whole after display base plate 100 to be cut according to scheduled display area 150,
To obtain independent display panel one by one.
Specifically, when detecting to display panel, position set by test point 200 is arranged in display area
150 side then must reserve extra region on display base plate 100 and dispose test point to arrange close to display area 150
200 position.If opening up opening 111 in display area 150, the position that test point 200 is disposed is arranged in the opening 111
It is interior, then the position on the display base plate 100 for being originally used for setting test point 200 can be saved, and then preferably plan

Vertical or horizontal display base plate region locating for test point 200, if the opening 111 using the embodiment of the present invention designs, display
Region 150 then can edge on the basis of original to display base plate 100 it is close, use and be currently used for setting test point
Vertical or horizontal 100 region of display base plate, improves the utilization rate of display base plate 100 well locating for 200, to save
Cost.In the concrete realization, 150 edge of each display area of display base plate 100 preferably reserves a part of region conduct
The buffer area of cutting facilitates cutting to process again to the profile of display panel after the completion, can also cut in display area 150
It is modified when edge damages.
Particularly, in the technique due to making display base plate now, i.e., multiple weld pads can be set in display base plate, so this
Invention in subsequent testing operation, i.e., using multiple weld pad as test point to be tested, without being additionally arranged
Test point.
Specifically, by form display base plate 100, showing first substrate 110 and the opposite combination of the second substrate 120
Multiple independent display areas 150 are marked off on substrate 100, and are cut on the first substrate 110 at each 150 edge of display area
At least one opening 111 is cut, test point 200 is set at opening 111 to detect to display area 150.To improve
The utilization rate of substrate, has saved cost.
Further, test point 200 is set at opening 111 to detect to display area, including will shown in advance
Show that the test cabling in region converges in opening, test point is corresponding with cabling to be connected to detect to display area.
Specifically, test point being arranged in opening, the test cabling of display area can converge to the periphery of the opening,
It allows the cabling between test point and display area to be laid out simpler, reduces wiring technique difficulty.
Shown in Figure 7, further, cabling includes the first cabling 131 for connecting red sub-pixel unit, connection green
Second cabling 132 of sub-pixel unit, the third cabling 133 for connecting blue subpixels unit, and connect the 4th of data line

Further, test point 200 is set to 120 surface of the second substrate.
Specifically, test point 200, will be in advance each scheduled generally when planning 120 surface of the second substrate
It is laid out in display area 150, after the second substrate 120 combines to form display base plate 100 with first substrate 110, cuts away
The predetermined position on 110 surface of first substrate is to expose the position of reserved test point 200, in above-described embodiment, in the first base
At least one opening 111 is cut on the first substrate at 150 edge of display area of plate 110, in order to allow test point 200 to expose
Come, allows subsequently through test point 200 and display panel is tested.
Further, each display area 150 is arranged in close to the side at 110 edge of first substrate in opening 111.
Specifically, each display area 150 is arranged in opening 111 can letter close to the side at 110 edge of first substrate
Change cutting technique, reduces the difficulty and cost of cutting technique.
Referring to fig. 2, be another display panel provided in an embodiment of the present invention production method schematic flow diagram, such as scheme
It is shown, this approach includes the following steps S21~S25:
