Abstract

According to one embodiment of the present invention, a display device may be variable between a first mode and a second mode. Specifically, in the first mode, the display device comprises a display module including a first part, a second part disposed below the first part, and a third part disposed between the first part and the second part and bent; a support part including a support plate disposed on the rear side of the first part and a plurality of support bars disposed on the rear side of the second part and the third part; a plate part including a magnet part disposed below the support part and movable in a first direction to move away from or closer to the first part; and a driving part disposed below the plate part. When the display device is converted from the first mode to the second mode, the third part is disposed parallel to the first part, and the magnet part moves in the first direction and overlaps the third part.

Description

Display Device The present invention relates to a display device, and more specifically, to a display device in which the deformation of the bending area of a display panel is improved. Generally, electronic devices that provide video to users, such as smartphones, digital cameras, laptop computers, navigation systems, and smart televisions, include a display device for displaying video. The display device generates video and provides it to the user through a display screen. With the recent advancement of display technology, various types of display devices are being developed. For example, flexible display devices that can be folded or rolled up are being developed. Flexible display devices, which can be transformed into various shapes, are easy to carry and can improve user convenience. A flexible display device can provide a user with a display screen of various sizes. For example, the flexible display device can operate in a basic mode and an extended mode. In the basic mode, a part of the flexible display module is exposed, and the remaining part can be placed inside the case in a folded state. The remaining folded part can be unfolded in the extended mode. However, in such a flexible display device, deformation may occur in the folded part. FIGS. 1 and FIGS. 2 are perspective views of a display device according to an embodiment of the present invention. FIG. 3 is a schematic diagram showing a cross-section of a display device according to an embodiment of the present invention. Figure 4 is a plan view of the display panel shown in Figure 3.

In this specification, where a component (or region, layer, part, etc.) is described as being "on," "connected," or "combined" with another component, it means that it may be directly placed/connected/combined with the other component, or that a third component may be placed between them. Identical reference numerals denote identical components. Additionally, in the drawings, the thicknesses, proportions, and dimensions of the components are exaggerated for the effective illustration of the technical content. "And/or" includes all one or more combinations that the associated configurations can define. Terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. A singular expression includes a plural expression unless the context clearly indicates otherwise. Additionally, terms such as "below," "lower side," "above," and "upper side" are used to describe the relationships between the components depicted in the drawings. These terms are relative concepts and are described based on the directions indicated in the drawings. Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Additionally, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and are explicitly defined herein unless interpreted in an ideal or overly formal sense. Terms such as "include" or "have" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
