Sliding and rolling mechanism, manufacturing method thereof and display device

Abstract

The invention discloses a sliding and rolling mechanism, a manufacturing method thereof and a display device, and belongs to the technical field of display. The sliding and rolling mechanism is used for supporting a flexible display screen and comprises a supporting substrate, the flexible display screen is arranged on the first face of the supporting substrate, and the supporting substrate can drive the flexible display screen to unfold or wind around a first axis; a plurality of protruding strips arranged at intervals in the unfolding direction of the flexible display screen are arranged on the face, away from the flexible display screen, of the supporting substrate, the length direction of the protruding strips is the same as the extending direction of the first axis, and a first groove is formed between every two adjacent protruding strips. In the embodiment of the invention, the raised lines are directly formed on the surface, deviating from the flexible display screen, of the supporting substrate instead of independent metal strips adopted in the prior art, so that adhesive connection is not needed; and the condition that the flexible display screen cannot normally slide and roll due to contact aggregation between the metal strips caused by easy debonding after long-time use or under high-temperature and high-humidity conditions is avoided.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a sliding scroll mechanism, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, with the continuous development of display technology, slideable display devices have gradually become a development trend of future mobile electronic products. The slide-and-roll display device can obtain a large display area in the unfolded state, which improves the viewing effect, and can obtain a small volume in the rolled state, which is convenient for users to carry. [0003] The realization of the sliding function of the sliding display device mainly depends on the metal support under the screen. For example, a single-layer or multi-layer thin metal sheet is attached to the back of the display screen with an adhesive to realize the sliding of the display screen, but its existence The problem of excessive rebound force, and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiment of this application is to provide a sliding roll mechanism and its manufacturing method, display device, which can solve the problem of the metal strips being connected by glue in the prior art. When used for a long time or under high temperature and high humidity conditions, it is easy to debond, which leads to the contact and aggregation between the metal strips, and then makes the flexible display unable to slide normally.
