Spliced screen and preparation method thereof

Abstract

The embodiment of the invention discloses a spliced screen and a preparation method of the spliced screen. The spliced screen comprises at least two panels, a filling layer and a first protective film layer, each panel comprises a light-emitting substrate and a packaging layer, the packaging layers package and cover the light-emitting substrates, the adjacent panels are arranged in a spliced mode, the side wall faces of the two adjacent packaging layers define a containing space with an opening in an enclosed mode, and the opening is located in the sides, away from the light-emitting substrates, of the packaging layers; the filling layer penetrates through the opening and is arranged in the accommodating space, and the elastic modulus of the filling layer is lower than or equal to that of the packaging layer; the first protective film layer is arranged on the surfaces, away from the light-emitting substrate, of the packaging layers of the at least two panels and connected with the filling layer located in the containing space. The risk that the first protective film layer is separated from the panel after bending is reduced, so that the stability of the first protective film layer after setting is guaranteed, and then the service life of the spliced screen is prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a splicing screen and a method for preparing a splicing screen. Background technique [0002] Light Emitting Diodes (LED) is a semiconductor electronic component that can convert electrical energy into light energy. Because of its small size, long service life, colorful colors, and low energy consumption, it is widely used in lighting, Displays, signal lights, backlights, toys and other fields. Flexible electronic products have attracted worldwide attention and developed rapidly. [0003] During the research and practice of the prior art, the inventors of the present application found that, during the manufacturing process of at least some flexible devices in flexible electronic products, PI films (polyimide Thin film), make related electronic devices on the PI film, and separate the glass substrate from the PI film after the related electronic devices are made to fo...

AI Technical Summary

Problems solved by technology

However, to make a large-size screen, flexible mini-LED screens need to be spliced ​​together. The splicing of flexible screens is difficult, and the joints are subject to stress factors during bending, and are easily deformed, resulting in separation from the upper and lower protective films. , affecting product life
