Abstract

In order to provide a hinge device that allows the flexible display panel to unfold flatly as a whole in the fully open state, and maintains the folded portion of the flexible display panel in a semicircular arc shape in the closed state, if the hinge device secures the first folded portion When the guide link element and the second fixed guide link element are folded back to the opposite fully closed state, the first cam drive part will operate, and the first and second fixed cam plates are respectively relative to the first and second fixed guide link elements. Rotate to face each other to angle α1. With the rotation of angle α1, the first movable guide link element and the second movable guide link element face each other with respect to the first and second fixed cam plates respectively. The direction is rotated to angle α2 so that the first main cam plate stands at right angles between the first and second fixed guide link elements.

Description

technical field [0001] The invention relates to a hinge technology of a turning part, which is configured to fold back a flexible soft display panel such as an organic electroluminescence (Electro Luminescence) panel or a liquid crystal panel in a display device. Background technique [0002] A display device has been proposed (Japanese Unexamined Patent Application Publication No. 2015-064570), in which a flexible display panel such as an organic EL panel or a liquid crystal panel is reversibly arranged, and the casing is connected and arranged by means of a hinge, so that one side The shell on one side and the shell on the other side can be opened and closed. In the display device disclosed in Japanese Patent Application Laid-Open No. 2015-064570, a flexible substrate is used to clamp both sides of a flexible display panel. If a pair of casings are stacked, the folded portion is formed into a bend with a predetermined radius in the elastic deformation region. shape. [0...
