Description
技术领域technical field
本发明属于显示屏检测技术领域，尤其涉及一种显示屏检测设备及显示屏的检测方法。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.
背景技术Background technique
随着显示屏尺寸的不断增大，显示屏在制程中难度逐渐增加，不良比例也随之上升。显示屏的生产厂商为了减少不良品流入客户端，一般会进行100％全检。而客户端为了提高生产直通率，确保成品出货品质，在显示屏上线组装前一般也会进行相应挑选。可见，显示屏的检测已成为生产制程中一件必不可少的事情。现有技术中，普遍采用传统的电缆插座连接显示屏，测试时，需先将显示屏的柔性电路板(FPC)插入电缆插座，对位难度大，难以快速将显示屏的FPC插入电缆插座内，另外，需要检测人员双手同时操作，测试时操作步骤较多且繁琐，操作难度大，测试效率低。此外，电缆插座需要反复扣紧和解开，非常容易损坏，需经常更换，物料损耗较大。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. 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.
