DETAILED DESCRIPTION
Example embodiments will now be described more fully hereinafter with reference to the accompanying drawings; however, they may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like numbers refer to like elements throughout.
It will be understood that, although the terms first, second, third etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings.
Spatially relative terms, such as “beneath”, “below”, “lower”, “under”, “above”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary terms “below” and “under” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. In addition, it will also be understood that when a layer is referred to as being “between” two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that when an element or layer is referred to as being “on”, “between”, “connected to”, “coupled to”, or “adjacent to” another element or layer, it can be directly on, between, connected, coupled, or adjacent to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to”, “directly coupled to”, or “immediately adjacent to” another element or layer, there are no intervening elements or layers present.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or the present specification and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Below, a display apparatus according to still another exemplary embodiment of will be described with reference to FIGS. 6 to 8.
FIG. 6 is an explored perspective view of a display apparatus according to still another exemplary embodiment. FIG. 7 is a top view of a display apparatus in FIG. 6. FIG. 8 is a cross-sectional view taken along a line I-I′ in FIG. 6.
A display apparatus illustrated in FIGS. 6 to 8 may be configured the same as a display apparatus illustrated in FIGS. 1 to 3 except that a touch panel 800 and a touch flexible printed circuit board 900 are further included. Thus, in FIGS. 6 to 8, description of constituent elements which are substantially similar to those in FIGS. 1 to 3 may be omitted.
The touch panel 800 may be disposed on a surface of a display panel 100 to at least correspond to a display area AA of the display panel 100. For example, the touch panel 800 may be disposed on the flexible display panel 100. An exemplary embodiment will be described using the case that the touch panel 800 is disposed on an upper surface 108 of the display panel 100. The touch panel 800 may detect an external touch to generate a touch location detecting signal. The touch panel 800 may include one of various structures of touch panels, e.g., one of various structures that are known in the art. For example, a capacitive touch panel or a surface acoustic touch panel may be used.
The touch flexible printed circuit board 900 may connect the touch panel and a driver printed circuit board 210 electrically. One end of the touch flexible printed circuit board 900 may be electrically connected to the touch panel 800, and the other end thereof may be electrically connected to the driver printed circuit board 210. The touch location detecting signal generated from the touch panel 800 may be transferred to the driver printed circuit board 210 via the touch flexible printed circuit board 900.
A portion extended from the one end of the touch flexible printed circuit board 900 may be bent along the short edge 101, e.g., the other surface 107 in FIG. 7, of the display panel 100. At least a part of the extended portion may be disposed on a lower surface 109 of the display panel 100.

The touch flexible printed circuit board 900 may be disposed between the lower surface 109 of the display panel 100 and a second surface 523 (see. FIG. 3) of the second fixing unit 520. The touch flexible printed circuit board 900 may be in contact with the second fixing unit 520, e.g., the touch flexible printed circuit board 900 may be between the second fixing unit 520 and the display panel 100.
FIG. 9 is a partial magnifying view of a touch flexible printed circuit board 900 and the second fixing unit 520 in FIG. 6.
Referring to FIG. 9, a surface of a touch flexible printed circuit board 900 may contact with the second surface 523 of the second fixing unit 520 at a first area AR1. The first area AR1 may have the same area as the second surface 523 of the second fixing unit 520 on a plane.
Although the touch flexible printed circuit board 900 is disposed between a display panel 100 and the second fixing unit 520, a step between display panel 100 and the second fixing unit 520 may be prevented by a shape of the touch flexible printed circuit board 900. Thus, the display panel 100 and the second cover member 320 may be concretely fixed by the second fixing unit 520.
In example embodiments, flexibility of the flexible display panel may be maintained by a shape of the fixing unit according to exemplary embodiments. Further, a driver circuit unit connected to the flexible display panel may be protected from an external impact.
By way of summation and review, a flexible display panel has been developed. The flexible display panel may use a flexible material such as a plastic instead of a glass. The flexible display panel may retain a display performance even when it may be bent, e.g., similar to paper. However, when a conventional flexible display panel experiences variation over a predetermined level the integrity of the display panel may be reduced. For example, the integrity of the flexible display panel may be reduced when signal lines formed at a non-display area are cracked.
In contrast, exemplary embodiments relate to maintaining the flexibility of the flexible display panel via a fixing unit. Further, embodiments relate to protecting a driver circuit unit connected to the flexible display panel from an external impact.
Example embodiments have been disclosed herein, and although specific terms are employed, they are used and are to be interpreted in a generic and descriptive sense only and not for purpose of limitation. In some instances, as would be apparent to one of ordinary skill in the art as of the filing of the present application, features, characteristics, and/or elements described in connection with a particular embodiment may be used singly or in combination with features, characteristics, and/or elements described in connection with other embodiments unless otherwise specifically indicated. Accordingly, it will be understood by those of skill in the art that various changes in form and details may be made without departing from the spirit and scope of the present invention as set forth in the following claims.
