Description

   Display device   

The present invention relates to a display device; specifically, the present invention relates to a display device in which a circuit unit is bent to the back side of a display panel.

Flat and curved display devices have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, host computers for transportation, personal computers, digital cameras, handheld video games, and the like. However, with the continuous improvement of specifications such as resolution, narrow bezel, and thinness, the design of the mechanism in the display device has also been tested.

Taking the liquid crystal display device as an example, in recent years, it has been required to achieve the appearance effect of a narrow frame or even a frame, so it needs to be adjusted for the traditional mechanism design. For example, a conventional liquid crystal display panel has one side connected to another substrate carrying a circuit element via a flexible circuit board for signal transmission and processing. However, under the design requirements of narrow frame or no frame, the flexible circuit board and the connected substrate need to be folded back to the back of the backlight module of the liquid crystal display panel and hidden. However, this setting often increases the overall thickness of the module, and cannot meet the demand for thinning.

It is an object of the present invention to provide a display device that can meet the visual requirements of narrow or no bezel.

An object of the present invention is to provide a display device which can reduce the overall module thickness.

One of the objectives of the present invention is to provide a display device, which can provide good structural support to the circuit unit bent to the back side of the display panel.

The display device includes a display panel, a backlight module, and a circuit unit. The display panel has a back side; the back side has an end edge. The backlight module faces the back side. The backlight module includes a casing and a bracket. On a projection plane parallel to the back side, the casing is not overlapped with the end edge, and an accommodation space is formed between the casing and the end edge. The bracket extends at least partially from the shell toward the end edge and projects into the accommodation space.

The circuit unit has a first terminal and a second terminal. The first end is connected to the display panel; the second end faces the back side because the circuit unit is bent. The second end extends into the accommodation space and is connected to the bracket. The bracket is located between the back side of the display panel and the second end of the circuit unit. With this design, at least part of the circuit unit can be accommodated in the accommodating space to reduce the thickness of the overall module, and stable structural support can be obtained.

The present invention provides a display device, which can be, for example, a non-spontaneous display panel such as a liquid crystal display panel or an electrophoretic display panel; and can be applied to, for example, a computer monitor, a television, a monitor, or a vehicle host. In addition, the display device can also be applied to other electronic devices, for example, as a display screen of a mobile phone, a digital camera, a handheld game instrument, and the like. However, it is not limited to this, and can be adjusted according to needs.

FIG. 1 is a perspective view of components of a display device according to an embodiment of the present invention. In order to facilitate understanding, FIG. 1 deliberately enlarges the pitches of the display panel 100, the backlight module 300, and the circuit unit 500. FIG. 2 is a schematic cross-sectional view taken along the line AA of the embodiment shown in FIG. 1. As shown in FIGS. 1 and 2, the display device 10 includes a display panel 100, a backlight module 300, and a circuit unit 500. The display panel 100 is, for example, a liquid crystal display panel and has a back side surface 110; the back side surface 110 has an end edge 111.

The backlight module 300 is disposed to face the back side surface 110 of the display panel 100, and generates light to enter the display panel 100 through the back side surface 110. As shown in FIG. 2, the backlight module 300 includes a casing 310 and a bracket 330. In this embodiment, for example, the backlight module 300 has a direct-type design, and a plurality of light sources 350 facing the back side 110 are arranged on the casing 310. However, in different embodiments, the backlight module 300 may also be designed in an edge-light type or other possible types, without being limited to the edge-light design. In addition, in this embodiment, the casing 310 is made of, for example, metal, and a support frame 320 made of, for example, a plastic material may be further provided in the casing 310, but it is not limited thereto. In different embodiments, the casing 310 may also be made of plastic material or a combination of both materials.

As shown in FIGS. 1 and 2, the housing 310 is not overlapped with the end edge 111 on the projection plane 200 parallel to the back side 110, and an accommodation space 400 is formed between the housing 310 and the end edge 111.
