The present invention relates to a display device, and more particularly to a light and thin display device.
2. Description of the Prior ArtIn order to meet user requirements for the image quality and appearance of display devices, narrow rim has gradually become the development trend of display devices. In order to achieve the purpose of narrow rim, some prior arts use the front frame of the panel module as an appearance part, and join the back plate and plastic frame of the panel module together. In general, the side edges of the back plate needs to be bent to a certain thickness to enclose the plastic frame so that the back plate and the plastic frame can be tightly joined. However, this junction of the back plate and the plastic frame will increase the width of the rim, which is not conducive to the light and thin design of the display device.
SUMMARY OF THE INVENTIONAn objective of the invention is to provide a display device. A joining structure between a plate member and an outer frame of the display device can provide sufficient joining strength and is conducive to a light and thin design, which can solve the above problem.
According to an embodiment of the invention, a display device includes a plate member, an outer frame, and a display panel. The plate member has a fringe portion and a joining structure formed on the fringe portion. The fringe portion has an edge, a first surface, and a second surface opposite to the first surface. The joining structure includes an opening structure passing through the first surface and the second surface. The opening structure extends to the edge. The outer frame has a parallel frame portion and a non-parallel frame portion extending from the parallel frame portion. The parallel frame portion and the fringe portion are joined together so that the outer frame and the plate member form an accommodating space. The parallel frame portion is parallel the fringe portion and is embedded into the joining structure. The non-parallel frame portion is non-parallel to the fringe portion. The parallel frame portion is coplanar with the first surface or the second surface. The display panel is accommodated in the accommodating space.
According to another embodiment of the invention, a display device includes a plate member, an outer frame, and a display panel. The plate member has a fringe portion and a joining structure formed on the fringe portion. The fringe portion has an edge, a first surface, and a second surface opposite to the first surface. The joining structure includes an opening structure and a raised portion. The opening structure passes through the first surface and the second surface. An orthographic projection of the raised portion on the first surface is located within an orthographic projection of the joining structure on the first surface. The outer frame has a parallel frame portion and a non-parallel frame portion extending from the parallel frame portion. The parallel frame portion and the fringe portion are joined together so that the outer frame and the plate member form an accommodating space. The parallel frame portion is parallel the fringe portion and is embedded into the joining structure. The non-parallel frame portion is non-parallel to the fringe portion. The parallel frame portion is coplanar with the first surface or the second surface. The display panel is accommodated in the accommodating space.
Compared with the prior art, in the display devices according to the invention, the parallel frame portion of the outer frame can be effectively joined without encapsulating the fringe portion of the plate member, so the overall structure thickness of the junction can be reduced, which is conducive to the light and thin design and solves the problem in the prior art.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

The outer frame 144 has a parallel frame portion 1442 and a non-parallel frame portion 1444 extending from the parallel frame portion 1442. The parallel frame portion 1442 and the fringe portion 1422 are joined together so as to make the outer frame 144 and the plate member 142 form the accommodating space 14a. The parallel frame portion 1442 extends parallel to the fringe portion 1422 and is embedded into the joining structure 1424, which can be achieved by insertion molding in practice. For example, the plate member 142 is made of a metal plate (for example by stamping), and the outer frame 144 is formed by plastic injection. The non-parallel frame portion 1444 and the fringe portion 1422 are non-parallel. In the embodiment, the overall plate member 142 extends parallel a reference plane P1 (indicated by chain lines in
Furthermore, in the embodiment, the raised portion 14244 protrudes from the second surface 1422c. The parallel frame portion 1442 is coplanar with the first surface 1422b and is coplanar with the top surface 14244a of the raised portion 14244. The combined thickness of the parallel frame portion 1442 and the fringe portion 1422 is equal to the thickness of the parallel frame portion 1442 (in the Z-axis direction perpendicular to the reference plane P1; therein, the Z-axis direction is indicated by an arrow in the figures), and is also equal to the entire thickness of the fringe portion 1422 and the joining structure 1424. This structural feature can prevent the frame assembly 14 from being too thick at the junction of the parallel frame portion 1442 and the fringe portion 1422, which is not conducive to the light and thin design. In other words, the parallel frame portion 1442 is only attached to the second surface 1422c and embedded into the joining structure 1424, instead of encapsulating the fringe portion 1422 (i.e. attached to the first surface 1422b and the second surface 1422c at the same time) to achieve the junction of the outer frame 144 and the plate member 142. Furthermore, in the accommodating space 14a, the parallel frame portion 1442 is coplanar with the first surface 1422b, which can reduce structural interference with components accommodated in the accommodating space 14a, and increase the utilization of the accommodating space 14a.
In the embodiment, as shown by
Furthermore, in the embodiment, the overall outer frame 144 is an n-shaped structure. The outer frame 144 is joined with three sides of the plate member 142 (including the fringe portion 1422 and other two fringe portions 1422′ and 1422″). Therein, the junction of the outer frame 144 with the fringe portions 1422′ and 1422″ is the same as the junction of the outer frame 144 with the fringe portion 1422, and will not be described in addition. However, it is not limited thereto in practice. The plate member 142 forms an accommodating slot 1426 at the opening of the n-shaped structure. The backlight module 162 includes a light bar 1622 disposed in the accommodating slot 1426 for providing required light. In addition, in practice, the bottom of the display device 1 can be connected to other structures (such as a support base). In practice, according to an actual product design of display device 1, the outer frame 144 can also be designed as a rectangular structure and joined with the periphery of the plate member 142.
As described above, both the opening structure 14242 and the raised portion 14244 of the joining structure 1424 have the effect of restraining the fringe portion 1422, and can be implemented alternatively in practice. In addition, in the embodiment, the parallel frame portion 1442 is only attached to the second surface 1422c and embedded into the joining structure 1424, which can make the junction of the outer frame 144 and the plate member 142 have a certain joining strength. In practice, the parallel frame portion 1442 also can be joined with the fringe portion 1422 of the plate member 142 in other ways. For example, in an embodiment, the parallel frame portion 1442′ also covers the top surface 14244a of the raised portion 14244, as shown by
