[0031] Embodiment 1

[0032] like Figure 1 and Figure 2 As shown, the utility model provides a touch screen edge collapse detection structure, comprising: a glass panel 1, having a touch area 11 and a frame area 12, wherein the frame area 12 is provided with a first detection line 2, a second detection line 31 and a binding area 3 at the periphery thereof;

[0033] The first detection line 2 is routed along the outer edge of the frame area 12 corresponding to the touch area 11, and a first detection PIN pin 21 and a second detection PIN pin 22 are respectively provided at the left and right ends of the binding area 3;

[0034] The second detection trace 31 is routed along the outer edge of the border area 12 corresponding to the binding area 3, and a third detection PIN pin 311 is provided between the binding area 3 and the first detection PIN pin 21, and a fourth detection PIN pin 312 is provided between the binding area 3 and the second detection PIN pin 22.

[0035] The binding area 3 includes a metal PIN pin 32, and the glass panel 1 is a capacitive touch screen CTP glass panel.

[0036] Since CTP is a large-scale process, a single sensor is only tempered on two sides. The process of cutting into single particles may cause the risk of glass edge collapse or edge sensor wiring micro-breakage. Therefore, the present application designs a circle of first detection wiring 2 on the periphery of the glass panel 1 to detect glass edge collapse by testing the impedance of the first detection wiring 2 and the second detection wiring, thereby eliminating potential hidden dangers and timely screening out defective products, saving costs for the company and avoiding adverse customer complaints from the client. At the same time, the first detection wiring 2 around the glass panel can also improve the anti-static performance and physical strength of the glass panel.

[0037] The working mode of this embodiment is described below.

[0038] After the CTP panel is cut into single CTP particles, Figure 3As shown, the transmitting end of the test fixture 4 is short-circuited with the first detection PIN pin 21 and the third detection PIN pin 311 respectively, and the other receiving end is short-circuited with the second detection PIN pin 22 and the fourth detection PIN pin 312 respectively. By passing the detection current to the second detection PIN pin 22 and the fourth detection PIN pin 312 respectively, and then receiving the detection current from the first detection PIN pin 21 and the third detection PIN pin 311 respectively, the test channel impedance of the first detection line 2 and the second detection line 31 are detected respectively; since the first detection line 2 and the second detection line 31 are wired along the outer edge of the frame area 12, when the edge of the touch screen has an edge collapse, the first detection line 2 or the second detection line 31 will be defective, thereby causing the corresponding test channel impedance to increase. If the glass edge collapses or the first detection line 2 and the second detection line 31 are slightly broken, this will cause a change in the resistance value. When the first detection line 2 and the second detection line 31 are slightly broken due to the cracking or damage of the glass edge, the resistance value usually increases or becomes unstable. This is because a slight break in the wiring will cause the current to be blocked at the break, thereby increasing the resistance value, which in turn determines whether the CTP panel is qualified.

[0039] In another embodiment, the transmitting end of the test fixture 4 shorts the second detection PIN pin 22 and the fourth detection PIN pin 312 respectively, and the other receiving end shorts the first detection PIN pin 21 and the third detection PIN pin 311 respectively to test the channel impedance and determine whether the CTP panel is qualified.

[0040] The present embodiment can be used to detect edge collapse of the glass panel 1 of the product before FPC binding through the above-mentioned structural design, so as to eliminate potential hidden dangers in advance and timely screen out defective products, thereby saving costs.

The first FPC PIN pin 521 is electrically connected to the first detection PIN pin 21, the second FPC PIN pin 522 is electrically connected to the second detection PIN pin 22, the third FPC PIN pin 523 is electrically connected to the third detection PIN pin 311, and the fourth FPC PIN pin 524 is electrically connected to the fourth detection PIN pin 312.

[0043] Through the above structural design, the glass panel is tested for edge collapse after being bound to FPC5. The first FPCPIN pin 521 and the third FPCPIN pin 523 of FPC5 are short-circuited through the test fixture 4, and the channel impedance is tested at the second FPCPIN pin 522 and the fourth FPCPIN pin 524 at the other end, so as to determine whether the CTP panel is qualified, thereby eliminating potential hidden dangers and timely screening out defective products, saving costs for the company and avoiding adverse customer complaints from the client.

[0044] In another implementation manner of the present embodiment, when the first FPC PIN pin 521 and the third FPC PIN pin 523 of FPC5 are open, the test fixture 4 can detect edge collapse of the glass panel 1, binding misalignment of the FPC gold finger 52, electrical connectivity of the ACF, or whether the edge of the FPC is torn, resulting in an open circuit in the wiring, by testing the channel impedance between the first FPC PIN pin 521 and the second FPC PIN pin 522, thereby eliminating potential hidden dangers and timely screening out defective products, saving costs for the company and avoiding adverse customer complaints from the client.
