Interpretation Not specifically defined here.

Fig. 1 is a view showing a display device according to an embodiment of the present invention, and Figs. 2A and 2B are views showing an exploded view of the display device shown in Fig. 1, and Fig. 3A is a cross-sectional view taken along line A-A in Fig. 1; Referring to FIG. 1 to FIG. 3A , the display device mainly includes a housing 100 , a frame module 200 , at least one fixing component 300 , a reflective component 400 , a light guide plate 500 , an optical film 600 , and a colloid . A display panel 800 and a light source module 900, wherein the light source module 900 includes a plurality of light emitting diodes facing the light guide plate 500, and the light provided by the light emitting diodes can be guided by the light guide plate 500. Lead to display panel 800.

The housing 100 includes a bottom plate 110 and four side walls 120. The side walls 120 are respectively connected to the four sides of the bottom plate 110, thereby surrounding the frame module 200, the fixing component 300, the reflective component 400, the light guide plate 500, the optical film 600, and the colloid 700. The display panel 800 and the light source module 900. In addition, at least one protrusion 111 is further formed on the bottom plate 110.

As shown in FIGS. 2B and 3A, the frame structure 200 has an L-shaped cross section and can be divided into a horizontal section 210 and an upright section 220. The horizontal section 210 is formed with at least one groove 211 and at least one hole 212, wherein the position of the groove 211 corresponds to the position of the protrusion 111 on the bottom plate 110, and the fixing element 300 can be in the manner shown in FIG. 3A. The hole 212 is inserted from above and fixed to the bottom plate 110. Alternatively, the frame structure 200 may be fixed to the bottom plate 110 by passing through the bottom plate 110 and entering the hole 212 in the horizontal section 210 as shown in FIG. 3B. The aforementioned fixing member 300 is, for example, a screw or a rivet.

In this embodiment, the horizontal section 210 is separated from the bottom plate 110. At a pitch, the upright section 220 extends downward from the horizontal section 210 to the bottom plate 110 and is in contact with the bottom plate 110. In addition, the upright section 220 is located between the light guide plate 500 and the side wall 120 of the housing 100. In this way, the light leaking from the side of the light guide plate 500 can be blocked by the upright section 220 of the frame structure 200 and the side wall 120 of the casing 100, so that the light leakage on the side of the display device can be effectively reduced.

Moreover, the upright section 220 of the frame structure 200 can be fixed to the side wall 120 of the casing 100 by adhesion or locking, so that the frame structure 200 is more firmly fixed to the casing 100.

As shown in Fig. 2A, in the present embodiment, the frame structure 200 has a C-shaped structure. The light source module 900 can be disposed on one side of the light guide plate 500, and the frame structure 200 can cover the remaining three sides of the light guide plate 500, so that each side of the display device has a good light shielding effect. In some embodiments, the frame structure 200 can also selectively shield one or both sides of the light guide plate 500. However, the frame structure 200 and the light source module 900 should be disposed on different sides of the light guide plate 500.

Continuing to refer to FIGS. 2B and 3A , the reflective element 400 is disposed on the bottom plate 110 of the housing 100 and located between the light guide plate 500 and the bottom plate 110 . It should be particularly noted that the horizontal section 210 of the frame structure 200 may extend toward the inner space of the housing 100 and contact the upper surface 510 of the light guide plate 500, that is, the horizontal section 210 may be in the display panel 800 and the light guide plate 500. The light guide plate 500 is in contact with each other, so that the light guide plate 500 can be pressed and fixed by the frame structure 200.

The optical film 600 is disposed between the light guide plate 500 and the display panel 800, and the light guide plate 500 is located between the optical film 600 and the reflective member 400. The optical film 600 has at least one ear 610 and a through hole 611 is formed in the ear 610. As shown in FIG. 4, when the optical film 600 is assembled, the ear portion 610 is accommodated. In the groove 211 of the horizontal section 210, and the stud 111 on the bottom plate 110 can pass through the through hole 611 to position the optical film 600. The aforementioned studs 111 may include a soft material to avoid scratching the aforementioned optical film 600.

In particular, the studs 111 should not protrude from the aforementioned through holes 611, whereby the display panel 800 can be flatly attached to a top surface 213 of the horizontal section 210 by the colloid 700.

Referring to FIG. 5, in the display device of another embodiment of the present invention, the colloid is omitted and the frame module 200 further includes a viscous member 230. The viscous element 230 is disposed on the horizontal section 210 of the frame module 200 to adhere the display panel 800 and the horizontal section 210.

In this embodiment, the top surface 231 of the viscous element 230 is aligned with the top surface 620 of the optical film 600. Thus, the top surface 620 of the optical film 600 can contact the display panel 800 to provide support, and the display panel 800 can be flattened It is disposed on the optical film 600 and the adhesive member 230.

As shown in the sixth and seventh embodiments, in some embodiments of the present invention, the frame structure 200 of the display device may also omit the aforementioned straight leg portion, so that one end of the horizontal segment portion 210 is directly fixed to the side wall 120 of the housing 100, for example, for example. It can be fixed by adhesion, welding or locking. Among them, the difference between the figures 6 and 7 is that the top surface 620 of the optical film 600 in the display device shown in Fig. 7 can contact the display panel 800 to provide support.

In summary, the present invention provides a display device by which the display panel can be stably and flatly disposed by providing the aforementioned frame structure. Furthermore, since the horizontal section in the frame structure can extend above the light guide plate to contact the light guide plate, parts for fixing the light guide plate and the reflective element can be omitted, and the display device can be reduced. The overall thickness. The upright section in the frame structure can effectively prevent light leakage on the side of the display device.
