Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, the invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the invention, so the present invention is not limited by the specific implementation disclosed below.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or i...

Abstract

The invention relates to a folding mechanism, comprising: an intermediate bracket; a left support structure including a first main support frame and a first auxiliary support frame; a right support structure including a second main support frame and a second auxiliary support frame ; The first main support frame and the second main support frame have a folded state and an unfolded state, and the first auxiliary support frame and the second auxiliary support frame also have a folded state and an unfolded state; the first main support frame and the second main support frame are in In the folded state, the first auxiliary support frame and the second auxiliary support frame are also in the folded state; when the first main support frame and the second main support frame are in the unfolded state, the first auxiliary support frame and the second auxiliary support frame are also in the folded state. is expanded. The first sub-support frame and the second sub-support frame are used to support the flexible display screen, and when the flexible screen is folded, they rotate to reserve space for the curved part of the flexible display screen; when unfolded, they can provide rigid support for the curved part on the back. A flexible display device having the above-mentioned folding mechanism is also proposed.

Description

technical field [0001] The present invention relates to the technical field of display terminals, in particular to a flexible display device and a folding mechanism thereof. Background technique [0002] For flexible folding device terminals, due to the limitation of the bending radius of the flexible screen during folding, a certain amount of reserved space needs to be reserved at the folding place, otherwise the screen will be bent abnormally during folding, which may cause permanent damage. In addition, if the connection part of the folding mechanism of the flexible folding device terminal is loose, it will also cause abnormal deformation of the screen, resulting in tension on the screen, and excessive deformation will cause damage to the screen. Therefore, the key issue of flexible folding is the protection of the screen when it is bent and the flatness when it is unfolded. The traditional folding scheme does not have a good protection scheme for the folded part. Conte...
