The embodiments are described in detail below, and the embodiments are only intended to be illustrative and not intended to limit the scope of the invention.

Please refer to FIGS. 1A-1B and 2A-2B. FIG. 1A and FIG. 1B are respectively a front perspective view and a rear perspective view of the display 100 according to an embodiment of the invention. 2A and 2B are exploded and partially enlarged views of the display 100 in accordance with an embodiment of the present invention.

The display 100 includes a display panel 110, a metal frame structure 120, an intermediate layer 130, a plurality of fasteners 140, and a rear case 150. The display panel 110 has a back plate 115, a first side surface 111, a second side surface 112, a third side surface 113, and a fourth side surface 114. The first side surface 111 is opposite to the third side surface 113, and the second side surface 112 is opposite to the fourth side surface 114. The second side 112 and the fourth side 114 are respectively connected between the first side 111 and the third side 113 to form a rectangle. The display panel 110 can be a liquid crystal display panel, a plasma display panel, or an organic electroluminescent display panel. In addition, the display panel 110 can also be a touch display panel.

The metal frame structure 120 includes a first plate member 121, a second plate member 122, and a third plate member 123 that are combined into one body. The first plate member 121 covers the first side surface 111 and the first surface S1 of the back plate 115. The second plate member 122 covers the second side surface 112 and the second surface S2 of the back plate 115. The third plate member 123 covers the third surface. The side surface 113 and one of the third surfaces S3 of the backing plate 115.

The metal frame structure 120 is formed, for example, by a stamping process, and its size and appearance substantially coincide with the size of the display panel 110, so that the first plate member 121, the second plate member 122, and the third plate member 123 can be combined separately after seamlessly. The first side surface 111, the second side surface 112, and the third side surface 113 of the display panel 110 are covered, but the display surface D of the display panel 110 is not covered. Therefore, the display surface D of the display panel 110 can It is completely presented, so that the visible area of the display surface D is not reduced as the conventional outer frame covers the surrounding surface of the display surface D.

In addition, in FIGS. 1A and 1B, the front edge F1 of the first plate member 121, the second plate member 122, and the third plate member 123 is almost flush with the display surface D of the display panel 110, and the first plate member 121, The respective side edges E1 of the second plate member 122 and the third plate member 123 are almost aligned with the corresponding side edges E2 of the rear case 150, so that the requirement of the full planar appearance of the display 100 can be achieved. In addition, the bottom side of the rear case 150 is further provided with a flange 152 extending to the fourth side surface 114 of the display panel 110 and covering a portion of the fourth side surface 114 to support the display panel 110 and interfacing with the display panel 110 Engage. From a frontal perspective, the flange 152 is concealed under the display panel 110 due to retraction, and a frameless visual effect can be achieved.

The first plate member 121, the second plate member 122 and the third plate member 123 are made of metal stamping, for example, and have a structural strength greater than that of a conventional plastic frame, and the thickness thereof is much smaller than that of a conventional plastic frame to make the display 100 The frame thickness is thinned, and the frame thickness of the display 100 is approximately equal to the plate thickness W of the first plate member 121, the second plate member 122, and the third plate member 123, as shown in FIG. 1A. In an embodiment, the thickness W of the first plate member 121, the second plate member 122, and the third plate member 123 is about 0.8 mm, which is smaller than the thickness of the conventional plastic frame 2.6 mm, so that the display 100 is The thickness of the frame can be reduced by about 69%. Therefore, the metal frame structure 120 used in the present invention is difficult to recognize whether there is an outer frame around the display panel 110 in appearance, so that a visual effect without a frame can be realized.

Referring to FIG. 2A, the back plate 115 of the display panel 110 is provided with a plurality of screw holes H engaged with the fasteners 140, which are disposed at the joint position between the display panel 110 and the metal frame structure 120, so that The lock 140 can pass through the first At least one of a plate member 121, a second plate member 122, and a third plate member 123, and first fixing the first plate member 121, the second plate member 122, and the third plate member 123 to the first plate member 115, respectively The surface S1, the second surface S2 and the third surface S3. In one embodiment, the backplane 115 is, for example, a metal backplane or a heat sink of the backlight module in the display panel 110. The backlight module has a light guide plate, a light source, a diffusion plate, and the like for use as a planar light source of the display panel 110.

In addition, the intermediate layer plate 130 is disposed between the display panel 110 and the rear case 150, and is made of plastic or other insulating material. In one embodiment, the metal frame structure 120 and the intermediate layer plate 130 are each provided with a through hole for the fastener 140 to pass through the corresponding through hole, and the metal frame structure 120 and the intermediate layer plate 130 are combined by the fasteners. The 140 is fixed to the back plate 115 of the display panel 110. In addition, between the intermediate layer plate 130 and the rear case 150, for example, a plurality of snap-fit structures 151, such as hooks and card slots, are provided. Therefore, the rear case 150 can be fixed to the back plate 115 of the display panel 110 by the intermediate layer plate 130.

In another embodiment, the rear case 150 can also be fixed on the back plate 115 of the display panel 110 by the metal frame structure 120, that is, the metal frame structure 120 and the rear case 150 without the intermediate layer plate 130 being required. For example, a plurality of snap-fit structures are provided to fasten the rear case 150 on the back plate 115 of the display panel 110.

Referring to FIGS. 2A and 2B, the first plate member 121 has a first outer plate portion 121a and a first inner plate portion 121b which is bent in a U-shape. The first outer plate portion 121a covers the first portion. On the side surface 111, the first inner plate portion 121b covers the first surface S1 of the back plate 115. The second plate member 122 has a planar second outer plate portion 122a and a second inner plate portion 122b bent in a U-shape, and the second outer plate The portion 122a covers the second side surface 112, and the second inner plate portion 122b covers the second surface S2 of the backing plate 115. The third plate member 123 has a flat third outer plate portion 123a and a third inner plate portion 123b which is bent in a U-shape. The third outer plate portion 123a covers the third side surface 113, and the third inner plate The portion 123b covers the third surface S3 of the backing plate 115.

In addition, the opposite ends of the second plate member 122 further have a first positioning member 122c and a second positioning member 122d. The first positioning member 122c is inserted into the first inner plate portion 121b which is bent in a U-shape (refer to In the enlarged view of FIG. 2B, the second positioning member 122d is inserted into the third inner plate portion 123b which is bent in a U-shape (see a partial enlarged view of FIG. 2B). Therefore, the second plate member 122 can structurally interfere with the first plate member 121 and the third plate member 123 by the first positioning member 122c and the second positioning member 122d, respectively, to avoid sliding when assembling the alignment, and can increase the structure. strength.

Next, please refer to the drawings of FIGS. 3A and 3B , which respectively show the assembly diagram of the first plate member 121 and the second plate member 122 and the assembly diagram of the second plate member 122 and the third plate member 123 .
