Problems solved by technology

However, the above process is now carried out manually, and it is difficult to completely align the upper film layer and the lower film layer, which is prone to errors
In addition, the existing upper film layer and lower film layer will be cleaned and dried before use, but when placed on the conveyor belt or placed on the table, it is easy to be contaminated with dust, resulting in obvious stains on the display screen after assembly

Abstract

The invention discloses an LED screen manufacturing method capable of improving yield. The LED screen manufacturing method is simple in structure and convenient to use, an upper template and a lower template can be quickly aligned, the upper template and the lower template cannot contact other articles in the drying, the pollution is prevented, and the yield manufacturing successful rate of the LED screen is greatly improved.

Description

technical field [0001] The invention belongs to the field of LED screens, and in particular relates to a manufacturing method of LED screens for improving the yield of good products. Background technique [0002] The LED display screen includes the upper film layer, the lower film layer and the middle circuit board layer. During assembly, the upper film layer or the lower film layer is usually manually coated with glue, and then the circuit board layer is placed on the lower film layer. Then manually cover the upper film layer and press it tightly. After the glue solidifies, the production is completed. However, the above-mentioned process is now carried out manually, and it is difficult to completely align the upper film layer and the lower film layer, which is prone to errors. In addition, the existing upper and lower film layers will be cleaned and dried before use. However, when placed on a conveyor belt or placed on a table, they are easily contaminated with dust, resu...
