Fig. 3 to Fig. 6 is please referred to, the present invention provides a kind of application method of above-mentioned liquid crystal display panel 100, including：It provides
Liquid crystal display panel 100 as described above；The liquid crystal display panel 100 is cut along the first cutting line 51, it is described
First cutting line 51 through viewing area 10 third at 13 and the 4th 14, obtain two pieces of nonstandard customization liquid crystal displays 60, described two
The side of the nonstandard customization liquid crystal display 60 of block all has source signal line area 21, to make the source in two pieces of nonstandard customization liquid crystal displays 60
Pole can access driving.
Specifically, the quantity of first cutting line 51 is two, it is described after being cut to liquid crystal display panel 100
The part that two the first cutting lines, 51 outside is located on liquid crystal display panel 100 forms two pieces of nonstandard customization liquid crystal displays
60。
Fig. 3 and Fig. 4 is illustrated when the liquid crystal display panel 100 is COF type liquid crystal display panel, along the first cutting line
51 pairs of liquid crystal display panels 100 carry out the process of machine cuts.When the liquid crystal display panel 100 is COF type liquid crystal display panel,
The side of the nonstandard customization liquid crystal display 60 of two pieces obtained all has gate line area 22.Preferably, the of the viewing area 10
Spaced Liang Ge gate line area 22, when cutting to the liquid crystal display panel 100, institute are equipped on the outside of three sides 13
It states the first cutting line 51 to be located between Liang Ge gate line area 22, thus the two pieces of nonstandard customization liquid crystal displays 60 obtained after cutting
Side all have a gate line area 22.
Fig. 5 and Fig. 6 is illustrated when the liquid crystal display panel 100 is GOA type liquid crystal display panel, along the first cutting line
51 pairs of liquid crystal display panels 100 carry out the process of machine cuts.When the liquid crystal display panel 100 is GOA type liquid crystal display panel,
Due to needing input circuit enabling signal STV when gate driving circuit area 23 starts to work, liquid crystal display panel 100 is cut
After cutting, the input of circuit start signal STV has been interrupted, therefore has also needed to carry out one of light to the nonstandard customization liquid crystal display 60 of acquisition
Gate driving circuit area 23 on every piece of nonstandard customization liquid crystal display 60 is accessed circuit start signal STV again, made every by cover process
Total driving TFT in gate driving circuit in the nonstandard customization liquid crystal display 60 of block is opened, and guarantees that gate driving circuit can normal work
Make.The subsequent frame that can be used blocks the cut edge of nonstandard customization liquid crystal display 60, to avoid edge light leakage.
One liquid crystal display panel 100 is divided into two blocks of nonstandard customization liquid crystal by the application method of above-mentioned liquid crystal display panel
Screen 60, improves the utilization rate of liquid crystal display panel 100, reduces the production cost of nonstandard customization liquid crystal display 60.
Fig. 7 to Figure 11 is please referred to, the present invention also provides another application methods of above-mentioned liquid crystal display panel 100, including：
Liquid crystal display panel 100 as described above is provided, the method using laser cutting will be located at outside the first side 11 of viewing area 10
Source signal line 30 in the source signal line area 21 of side is cut off by root, is obtained one piece of whole face and is shown with liquid crystal display 200, described whole
Face, which is shown, can be used as TV panel with liquid crystal display 200.
The liquid crystal display panel 100 is as whole face screen in use, due to the source signal line positioned at 10 two sides of viewing area
Source signal line 30 in area 21 can simultaneously drive panel, to cause signal disorder, it is therefore desirable to will be located at display
Source signal line 30 in the source signal line area 21 of 10 side of area is cut off, and traditional cutting method is the side using machine cuts
Method directly cuts away in the source signal line area for being located at viewing area side along the edge of viewing area, but will cause liquid crystal display in this way
Panel damage, and exposed source signal line be corroded after be likely to cause signal disorder in face.The present invention is using sharp
The method of light cutting, source signal line 30 is cut off, avoid causing to damage to liquid crystal display panel 100 using the energy of laser beam
Wound signal will not impact in opposite when cut-off source signal line 30 occurs bad in back-end process.
Fig. 7 and Fig. 8 is illustrated when the liquid crystal display panel 100 is COF type liquid crystal display panel, to LCD display
The process that plate 100 is cut by laser；Fig. 9 and Figure 10 is illustrated when the liquid crystal display panel 100 is GOA type LCD display
When plate, process that liquid crystal display panel 100 is cut by laser.
Specifically, as shown in Fig. 7, Fig. 9, Figure 11, along the second cutting line 52 by the source signal in source signal line area 21
Line 30 is cut off by root, second cutting line 52 be less than with the first side 11 of viewing area 10 at a distance from second cutting line 52 and
The distance of 10 one side edge of separate viewing area in source signal line area 21, i.e., described second cutting line 52 is close to 10 side of viewing area
Setting is cut so as to the site on source signal line 30 close to viewing area 10.
The application method of above-mentioned liquid crystal display panel will be located at the source electrode of 10 side of viewing area using the method for laser cutting
Source signal line 30 in signal wire area 21 is cut off by root, is obtained one piece of whole face and is shown with liquid crystal display 200, cuts with traditional machinery
Segmentation method is compared, and the laser cutting method not will cause the damage of liquid crystal display panel 100, also can be avoided exposed source
Pole signal wire 30, which is corroded, causes signal disorder in face, while improving process rate.
In conclusion liquid crystal display panel of the invention can be realized a screen dual-purpose, use value with higher.This hair
One liquid crystal display panel is divided into two pieces of nonstandard customization liquid crystal displays by the application method of the first bright liquid crystal display panel, is mentioned
The high utilization rate of liquid crystal display panel, reduces the production cost of nonstandard customization liquid crystal display.Second of liquid crystal of the invention
Show that the application method of panel uses the method for laser cutting by the source signal in the source signal line area for being located at viewing area side
Line is cut off by root, is obtained one piece of whole face and is shown with liquid crystal display, compared with traditional mechanical cutting method, the laser cutting method
It not will cause liquid crystal display panel damage, can be avoided exposed source signal line yet and be corroded and cause signal in face disorderly
Disorderly.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding changes and modifications are made in design, and all these change and modification all should belong to the claims in the present invention
