Embodiment Construction

[0023] Some vocabulary is used in the specification and claims to refer to specific components. Those skilled in the art will appreciate that hardware manufacturers may call with different nouns. This specification and claims do not use the difference between the name as a differential component, but is used as a distinction between the components in functional differences. As mentioned in the presentation and claims, "including" is an open term, so it is explained to "including but not limited to". "Substantially" means within an acceptable error range, those skilled in the art to solve the technical problem within a certain error range, to achieve the basic technical effect. In addition, the "couple" is intended to mean any direct and indirect electrical coupling means. Accordingly, described herein if a device is coupled to a second device, said first means represents may be directly electrically coupled to the second means, or by other means or indirectly electrically coupling...

Abstract

The invention discloses a display device, and relates to the technical field of display, and the display device comprises a flexible display panel which has a flattened state and a furled state; a furling assembly which comprises a rotating shaft, a gear rack transmission mechanism gear and a motion transmission assembly for connecting the rotating shaft with the gear rack transmission mechanism gear, wherein the rotating shaft is fixedly connected with the flexible display panel, the rotating shaft is used for rolling the flexible display panel, a gear of the gear rack transmission mechanism comprises a rack, the extension direction of the rack is parallel to the extension direction of the rotating shaft, and rotation of the rotating shaft is converted into linear transmission of the rack through a motion transmission assembly; and a frame, wherein the furling assembly is located in the frame, and a limiting block is arranged on the inner wall of the frame. When the flexible display panel is in a flattened state, the racks make contact with the limiting blocks. According to the invention,the gear rack transmission mechanism is adopted, limiting of the limiting blocks is matched, and the situation that the flexible display panel is excessively stretched can be effectively avoided.

Description

Technical field [0001] TECHNICAL FIELD The present application relates, in particular, relates to a display device. Background technique [0002] As the technology matures flexible display, a display apparatus having a folding function (e.g., a mobile phone is folded, the folding or folding tablet PC, etc.) is a major trend in the future; a display portion having a display device which is foldable folding function. With respect to the conventional display device, a display device having a folding function may be implemented to switch the physical dimensions of the display device, greatly improved user experience. [0003] Currently, a display apparatus having a folding function typically includes a flexible display panel, a flexible display panel may preferably be crimped or bent in a display device; however, the flexible display panel by the conventional crimped state to a flat state, easily lead the screen is drawing excessive damage, display panel affect the display. Inventiv...
