no. 1 approach

[0035] Figure 1A is a perspective view schematically illustrating an unfolded state of the foldable display device according to the first embodiment of the present disclosure, Figure 1B is to zoom in Figure 1A A cross-sectional view of a portion of a foldable display device, and Figure 1C is a cross-sectional view schematically illustrating a folded state of the foldable display device according to the first embodiment of the present disclosure.

[0036] Such as Figure 1A As shown, the foldable display device 100 is divided into a first display area EA1 and a second display area EA2 for realizing images with respect to the folding axis FX. The first display area EA1 is defined by the first display panel 111 , and the second display area EA2 is defined by the second display panel 113 .

[0037] The first display area EA1 and the second display area EA2 may implement different images, or may simultaneously implement one image as shown in the figure.

no. 2 approach

[0103] Figure 6A is a perspective view schematically illustrating a hinge system according to a second embodiment of the present disclosure, Figure 6B is to zoom in Figure 6A An exploded view of region C of .

[0104] Such as Figure 6A As shown, the hinge system 130 according to the second embodiment of the present disclosure is divided into a first hinge part 130a and a second hinge part 130b.

[0105] The first hinge part 130a includes a first slat 131 , a second slat 133a and a third slat 133b. The first slat 131 has a bar shape and extends in the first direction (ie, the X direction in the drawing). The second slat 133a and the third slat 133b respectively have a bar shape and extend from both ends of the first slat 131 in a second direction (ie, Y direction in the drawing) perpendicular to the first direction. The first slat 131, the second slat 133a and the third slat 133b form a shape similar to a U shape.

[0106] The first hinge part 130a also includes a fou...

Abstract

A foldable display device includes a display panel including first and second display areas and a folding part between the first and second display areas; first and second system units disposed under the display panel and corresponding to the first and second display areas, respectively; an elastic plate between the display panel and the first and second system units; and a hinge system corresponding to the folding part and disposed on the rear surfaces of the first and second system units, and including a first hinge portion on the rear surface of the first system unit and a second hinge portion on the rear surface of the second system unit, wherein the first and second hinge portions are rotatably hinge-combined with each other.

Description

technical field [0001] The present disclosure relates to a foldable display device, and more particularly, to a foldable display device capable of light weight and thin profile with improved durability. Background technique [0002] Recently, as the mature information age has entered, interest in information displays that process and display large amounts of information has grown. In view of this, various flat panel display devices have been developed and have drawn attention. [0003] Specific examples of flat panel display devices include liquid crystal display (LCD) devices, plasma display panel (PDP) devices, field emission display (FED) devices, electroluminescence display (ELD) devices, organic light emitting diode display (OLED) devices. Flat panel display devices exhibit excellent properties of thinness, light weight, and low power consumption, and have rapidly replaced cathode ray tubes (CRTs). [0004] However, since the flat panel display device uses a glass sub...
