In the prior art, the traditional cable socket is generally used to connect the display screen. When testing, the flexible circuit board (FPC) of the display screen needs to be inserted into the cable socket first. The alignment is difficult, and it is difficult to quickly insert the FPC of the display screen into the cable socket. , In addition, the inspector needs to operate with both hands at the same time, the operation steps are many and cumbersome during the test, the operation is difficult, and the test efficiency is low
In addition, the cable socket needs to be fastened and unfastened repeatedly, which is very easy to damage, needs to be replaced frequently, and has a large material loss

The invention is applicable to the technical field of display screen detection, and discloses a display screen detection device and a display screen detection method. The display screen detection device includes a device main body, the device main body is connected with a main body positioning structure for positioning the display screen main body, and the device main body is also provided with a cable positioning structure for positioning the flexible circuit board on the display screen; the device main body is connected to There is a contact device, and the contact device is connected with a driving device for driving the sliding of the contact device; the contact device includes a pressing block and is connected to the pressing block and is used to contact the conductive contact piece on the flexible circuit board. The conductive part is connected to the display driving module through a cable. The detection method of the display screen adopts the above-mentioned display screen detection equipment. The display screen detection device and the detection method of the display screen provided by the present invention do not need to use a cable socket for repeated plugging and unplugging, and the detection operation is simple and easy, the operation difficulty is low, and the detection efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of display screen detection, and in particular relates to a display screen detection device and a display screen detection method. Background technique [0002] As the size of the display screen continues to increase, the difficulty in the manufacturing process of the display screen gradually increases, and the proportion of defective screens also increases. In order to reduce the flow of defective products to the client, display screen manufacturers generally conduct 100% full inspection. In order to improve the straight-through rate of production and ensure the quality of finished product shipments, the client will generally make corresponding selections before the display is assembled on the line. It can be seen that the detection of the display screen has become an essential thing in the production process. In the prior art, the traditional cable socket is generally used to connect the display screen. ...
