Display device

The present invention relates to a display device, and more particularly to a display device having a flexible flexible panel.

A conventional curved display device is configured to sandwich a flexible display panel between two outer frames having curved abutting surfaces to force the flexible display panel to deform along the curved pressing surfaces of the two outer frames. It has a curved surface shape.

In addition, since the outer flexible display panel is provided with a cable and an electronic component (such as a wafer) at the edge of the flexible display panel, when the two outer frames are sandwiched with the flexible display panel, the cable and the electronic component may be combined with one of the outer frames. The inner edge of the frame interferes. In this regard, a notch is formed correspondingly at the inner edge of the frame body having an arc-shaped pressing surface on one of the outer frames to avoid the occurrence of interference by evading the wire and the electronic components. However, since the notch is formed by recessing the inner edge of the frame toward the outer edge, the arc-shaped pressing surface of the frame is pressed to reduce the area of the flexible display panel, thereby causing the bending curvature of the flexible display panel to be different and affecting the scratch. The display effect of the display panel. Moreover, the provision of the notch will result in the contour of the inner edge of the frame being not flat and having the presence of an angled structure. When the frame is pressed against the flexible display panel, the holding force of the angled structure may cause stress concentration on the flexible display panel, causing excessive stress on the flexible display panel to cause cracks.

Therefore, it is necessary to improve the structure of the outer frame of the display device to avoid the outer frame. It has a negative impact on the flexible display panel.

The present invention is directed to a display device that avoids adversely affecting a flexible display panel by a frame outside the display device.

The display device disclosed in the present invention comprises a first frame body, a second frame body, a flexible panel and a row of wires. The first frame includes two opposing first straight segments and two opposing first curved segments connected between the two first straight segments. The second frame includes two opposing second straight segments and two opposing second curved segments connected between the two second straight segments. Each of the second curved segments has an opposite inner side surface and an outer side surface, and the two inner side surfaces of the second second curved portion face each other.
