[0002] The present invention relates to a display device, and more particularly to a display device capable of preventing light leakage at the corners of a display panel. Background Art

[0003] In recent years, display devices have been widely used in various different electronic products, such as notebook computers, desktop computers, televisions, etc. With the demand for the enlargement of display panels, the self-weight of the display panel will cause a tight fit between the edge of the display panel and the bottom edge frame of the display device. Therefore, when the display device operates for a period of time and the display panel is deformed due to heat, the edge of the display panel is restricted by the contact with the edge frame and cannot change the warpage degree, resulting in light leakage at the lower corners of the display panel. Summary of the Invention

[0004] The present invention provides a display device that can effectively improve the phenomenon of light leakage at the corners of the display panel to enhance the display quality of the display device.

[0005] The display device provided by the present invention includes a display panel, a support frame, and a low-friction object. The display panel includes a display surface, a back surface, and a side surface. The display surface and the back surface are opposite to each other, and the side surface is adjacent to the display surface and the back surface. The support frame includes a first limiting portion, a second limiting portion, and a support structure. The first limiting portion and the second limiting portion are connected. The first limiting portion corresponds to the side surface of the display panel, and the second limiting portion corresponds to the back surface of the display panel. The support structure is disposed on the first limiting portion and extends toward the side surface of the display panel. The support structure has a bearing surface, wherein the side surface has a corresponding area opposite to the bearing surface. The low-friction object is disposed on at least one of the bearing surface of the support structure and the corresponding area, so that the low-friction object is interposed between the bearing surface and the corresponding area.

[0006] In an embodiment of the present invention, the above-mentioned low-friction object has a coefficient of friction less than or equal to 0.1.

[0007] In an embodiment of the present invention, the material of the above-mentioned low-friction object is Teflon.

[0008] In an embodiment of the present invention, the above-mentioned corresponding area, low-friction object, and bearing surface are stacked together in a gravity direction.

[0009] In an embodiment of the present invention, when the above-mentioned display panel is deformed by heat, the corresponding area is offset in the bearing surface away from the second limiting portion via the low-friction object.

[0010] In an embodiment of the present invention, the number of the above-mentioned support structures is plural, and they are disposed at the corners of the support frame adjacent to the first limiting portion.

[0011] In an embodiment of the present invention, the above-mentioned low-friction object is disposed in the corresponding area, the partial display surface adjacent to the corresponding area, and the partial back surface adjacent to the corresponding area.

[0012] In an embodiment of the present invention, the above-mentioned display device further includes a front frame and a back plate. The front frame is adapted to be fixed to the back plate to form an accommodation space. The display panel and the support frame are disposed in the accommodation space, and the display panel is located between the front frame and the support frame.

[0013] In an embodiment of the present invention, the above-mentioned display device further includes a first buffer material disposed between the front frame and the display panel.

[0014] In an embodiment of the present invention, the above-mentioned display device further includes a second buffer material disposed between the back surface and the second limiting portion.

[0015] In an embodiment of the present invention, the above-mentioned low-friction object is further disposed between the back surface of the display panel and the second buffer material.

[0016] In the present invention, by disposing a low-friction object on the bearing surface of the support structure of the support frame and / or in the area corresponding to the support structure and the display panel (such as the corresponding area), the frictional force between the display panel and its support structure can be reduced, so that when the display panel is deformed by heat, it will not be stuck by the support structure due to being tightly fitted with the support structure and unable to shift, resulting in light leakage at the corners of the display panel, effectively improving the display quality of the display device.

[0021] Figure 1is a partial exploded view of a display device according to an embodiment of the present invention, as Figure 1 shown, the display device 10 includes a display panel 12, a support frame 14, and a low-friction member 16. The display panel 12 includes a display surface 121, a back surface 122, and a side surface 123. The display surface 121 and the back surface 122 are opposite to each other, and the side surface 123 is adjacent to the display surface 121 and the back surface 122. In one embodiment, the display panel 12 is, for example, a liquid crystal display panel. The side surface 123, for example, includes an upper side surface (not shown), a lower side surface 123a, a left side surface 123b, and a right side surface 123c.

[0022] The support frame 14 includes a first limiting portion 18, a second limiting portion 20, and a support structure 22. The first limiting portion 18 and the second limiting portion 20 are connected. The first limiting portion 18 corresponds to the side surface 123 of the display panel 12, and the second limiting portion 20 corresponds to the back surface 122 of the display panel 12. In one embodiment, the first limiting portion 18 and the second limiting portion 20 are connected together at a substantially perpendicular relationship. The first limiting portion 18 is adapted to be framed around the periphery of the side surface 123 of the display panel 12. Correspondingly, for the upper side surface, the lower side surface 123a, the left side surface 123b, and the right side surface 123c, the first limiting portion 18 has an upper limiting frame (not shown), a lower limiting frame 18a, a left limiting frame 18b, and a right limiting frame 18c corresponding to the upper side surface, the lower side surface 123a, the left side surface 123b, and the right side surface 123c respectively.

[0023] The support structure 22 is disposed on the first limiting portion 18 and extends toward the adjacent side surface 123 of the display panel 12. The number of the support structures 22 is, for example, two are provided on each of the upper limiting frame, the lower limiting frame 18a, the left limiting frame 18b, and the right limiting frame 18c. In one embodiment, the support structure 22 is disposed at a corner adjacent to the first limiting portion 18. In Figure 1 the embodiment shown, only two support structures 22 located on the lower limiting frame 18a, one support structure 22 located on the left limiting frame 18b, and one support structure 22 located on the right limiting frame 18c are shown. Each support structure 22 has a bearing surface 221, and the bearing surface 221 faces a part of the side surface 123. Among them, a corresponding area 124 defining the side surface 123 faces the bearing surface 221. The corresponding area 124 is, for example, at a side surface 123 near a corner of the display panel 12.

[0024] Continuing the above description, the low-friction member 16 is disposed on at least one of the bearing surface 221 of the support structure 22 and the corresponding area 124. Among them, the low-friction member 16 has a coefficient of friction less than or equal to 0.1. In one embodiment, the material of the low-friction member 16 is Teflon, and the low-friction member 16 is, for example, a Teflon tape.

[0025] Figure 2 is a partial cross-sectional structural view of a display device according to an embodiment of the present invention, asFigure 2 As shown, the display panel 12 is disposed on the support structure 22, and the second limiting portion 20 is located on the back surface 122 of the display panel 12, wherein the low-friction object 16 is interposed between the bearing surface 221 and the corresponding area 124 (labeled in Figure 1 ). In the partial cross-sectional structural schematic diagram as shown in Figure 2 , for example, taking the lower side surface 123a of the display panel 12 as an example, the low-friction object 16 is disposed on the bearing surface 221 and the corresponding area 124 of the lower side surface 123a, and is further disposed on a partial display surface 121 and a partial back surface 122 adjacent to the corresponding area 124. However, it is not limited thereto, and the low-friction object 16 may be disposed only on the bearing surface 221 or only on the corresponding area 124.

[0026] As shown in Figure 2 , the display device 10 further includes a front frame 24, a back plate 26, and an optical component 30. The front frame 24 is adapted to be fixed to the back plate 26 to form an accommodation space 28. The display panel 12 and the support frame 14 are disposed in the accommodation space 28, and the display panel 12 is interposed between the front frame 24 and the support frame 14. The optical component 30 is, for example, disposed between the support frame 14 and the back plate 26. The optical component 30 may, for example, include a light source, an optical film, and / or a light guide plate, etc.

[0027] Moreover, in an embodiment, the display device 10 further includes a first buffer material 32 and a second buffer material 34. The first buffer material 32 is disposed between the front frame 24 and the display panel 12, and the second buffer material 34 is disposed between the back surface 122 of the display panel 12 and the second limiting portion 20. In an embodiment, the first buffer material 32 and the second buffer material 34 are, for example, foams, so as to assist in clamping the display panel 12 between the front frame 24 and the second limiting portion 20. In an embodiment, the above-mentioned low-friction object 16 may further be disposed between the back surface 122 of the display panel 12 and the second buffer material 34.

[0028] Generally speaking, for the convenience of assembling the display panel 12 and the support frame 14, there is a gap between the display panel 12 and the support frame 14 instead of a tight fit; and when the display device 10 is erected, as shown in Figure 2 , under the action of gravity, the corresponding area 124 (labeled in Figure 1 ) of the side surface 123a of the display panel 12, the low-friction object 16, and the bearing surface 221 of the support structure 22 are stacked together in the direction of the gravity action G, and the display panel 12 is supported by the support structure 22. As the display device 10 operates for a period of time and the display panel 12 is thermally deformed, for example, when the warpage degree changes, the corresponding area 124 can be offset on the bearing surface 221 with the assistance of the low-friction object 16, and the offset direction D1 is, for example, perpendicular to the direction of the gravity action G. In an embodiment, Figure 3It is a schematic partial cross-sectional structure diagram of an application state of a display device according to an embodiment of the present invention. As Figure 3 shown, the corresponding area 124 (marked in Figure 1 ) and its adjacent corner portion of the display panel 12 will shift towards the front frame 24 in response to the change in the warping degree, causing the display panel 12 to be close to the first buffer material 32. At this time, the display panel 12 and the first buffer material 32 are in an adjacent state. In this way, the light leakage phenomenon at the corner of the display panel 12 can be avoided by the shift of the partial display panel 12.

[0029] According to the above, in the display device according to the embodiment of the present invention, setting a low-friction object on the bearing surface of the support structure of the support frame and / or setting a low-friction object in the area corresponding to the support structure and the display panel (such as the corresponding area) can be used to reduce the frictional force between the display panel and its support structure, so that when the display panel is deformed by heat, it will not be stuck by the support structure due to being tightly fitted with the support structure and unable to shift, resulting in the light leakage phenomenon at the corner, effectively improving the display quality of the display device.

Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention.
