Description

Display device

The present invention relates to a display device, and more particularly to a display device suitable for use in a narrow bezel.

The current trend of display devices is to develop toward a narrow bezel, which not only reduces the overall size of the display device, but also achieves a larger display area, and can increase the aesthetic and modern design. However, for the conventional display device having a narrow bezel, there are still problems to be solved.

For the edge-lit backlight module, the narrow-frame display device means that the display area of the panel is closer to the edge of the light guide plate than the conventional display, so the light of the backlight source leaks from the side of the panel. It is more likely to occur, resulting in uneven brightness around the display area. In addition, for some narrow-frame display devices, the panel is directly carried by the backlight module, and in such a structure, the panel is often placed directly on the optical film, which is liable to cause high-temperature curling of the optical film ( Waving).

In view of the above, an object of the present invention is to provide a display device in which a carrier is provided with at least one side wall, and a frame is disposed outside the carrier for carrying the panel, and the peripheral wall of the frame adopts a structurally formable small thickness. The problem that the light leakage of the light guide plate is too close to the display area of the panel to cause light leakage is visually observed, and the panel is carried by the frame, does not directly press on the optical film, and also avoids the problem that the optical film is curled or scratched. Since the carrier member is provided with at most one side wall, the optical film can be directly mounted on the light guide plate without bending, and the optical film is not damaged.

An embodiment of the display device provided by the present invention includes a backlight module, a frame, a support member, and a panel. The backlight module includes a carrier, a light emitting component, a light guide plate, and at least one optical film. The light guide plate is disposed on the plate body and adjacent to the first side, and the light guide plate is disposed on the plate body. The plate body has a first side and a second side. The first side is disposed opposite to the second side. And adjacent to the light emitting component, the optical film is disposed on the light guide plate. The frame has a peripheral wall and an extension portion. The peripheral wall surrounds the backlight module. The extension portion extends from the peripheral wall toward the center of the backlight module. The peripheral wall includes an opposite first portion and a second portion. The first portion corresponds to the first side and the second portion corresponds to the first side and the second portion. The support corresponds to the second side, a gap is formed between the first portion and the first side, the lower edge of the second portion abuts against the plate body and the abutment portion is adjacent to the second side, and the support member is disposed on the light. Between the assembly and the extension of the frame, the extension is supported by a support member, the panel is carried on the frame, and the extension of the frame is interposed between the optical film and the panel.

Another embodiment of the display device provided by the present invention includes a backlight module, a frame, a support member, and a panel. The backlight module includes a carrier member, a light emitting assembly, a light guide plate, and at least one optical film. The carrier is composed of a plate body, a side wall and a top wall.

The peripheral wall surrounds the backlight module. The extension portion extends from the peripheral wall toward the center of the backlight module. The peripheral wall includes opposite first portions and second portions. The first portion corresponds to the first side and the second portion. The portion corresponds to the second side, a gap is formed between the first portion and the first side, the lower edge of the second portion abuts against the plate body and the abutment portion is adjacent to the second side, and the support member is disposed on the frame Between the extension and the top wall of the carrier, the extension is supported by the support member, and the panel is carried on the frame, and the extension of the frame is interposed between the optical film and the panel.

The panel is provided with at most one side wall, and a frame is disposed outside the backlight module to carry the panel, and the peripheral wall of the frame adopts a structurally formable small thickness, so that the panel can be made even if applied to a narrow frame display device. The display area is kept at a sufficient distance from the edge of the light guide plate, even if there is light leakage, it is not easy to be visually observed. In addition, the panel is carried by the frame, does not directly press on the optical film, and also avoids high temperature curling or scratching of the optical film. The problem, and since the carrier is provided with at most one side wall, the optical film can be directly mounted on the light guide plate without causing the optical film to be damaged by interference with the housing during assembly.
