Furthermore, this creation is used by the grading staff to assist in positioning the assembly of the optical sheet to the 7-back panel.梦照;1图' is a three-dimensional exploded view of the device according to an embodiment of the present invention.疋显器: 乂:: It is a desktop display device, such as a notebook computer, flat (such as raising, a 1 Nintendo _, etc.) = 2 This is limited. In other words, the display device of the present invention can be fabricated on any electronic product that is not visible, as long as it is fixed on the back panel of its display device and does not wish to cause foreign body intrusion or leakage. The above concepts can be solved by applying the concept of this creation. As shown in FIG. 1 , in the present embodiment, the display device of the present invention mainly comprises a back plate 10 , a retroreflective sheet 12 , a light guide plate 14 , an optical film 16 a , an optical film 16 b , an optical film 16 c , and a plastic frame 18 .

The light guide plate μ of the display device directs the light emitted from the light source 22 to the light reflecting sheet 12, and the light reflecting sheet 12 is uniformly reflected by the light guided by the light guiding plate 14. The optical film 16a, the optical film 16b, and the optical film 16c of the display device are sequentially disposed on the light guide plate. Therefore, the light reflected by the retroreflective sheeting 12 is then sequentially passed through the optical film 16a, the optical film 16b, and the optical film 16c after passing through the light guide plate 14, thereby providing a panel module of the display device (not shown). A uniform surface source. M421511 «• month refers to Figure 2A. Fig. 2A is a partial perspective view showing the backing plate ι of Fig. 1 in which the cushioning member 20 has not been engaged with the through hole l〇〇a. As shown in FIG. 1 and FIG. 2A , in the embodiment, the back plate 10 of the display device further includes a substrate 10 〇 and a sidewall of the connection substrate 1 于 in the manufacturing process, and the sidewall 1 背 of the back plate 1 〇 2 can be formed by bending (for example, by a stamping process) the edge of the backsheet 10. The side wall 102 of the back panel 1 has a locking hole 1〇2a. The locking holes 1〇2& on the side wall 〇2 are used to interlock with the front cover (not shown) of the display device. Since most of the current devices are thinner as the mainstream trend, if the locking holes 102a' are formed on the short and narrow side walls 1〇2, the strength of the side walls 1〇2 adjacent to the locking holes 1〇2a may be weakened. And the structural instability of the backboard 10 is increased. Therefore, the through hole 100a is punched out from the substrate 1 〇〇 2 adjacent to the side wall 1 〇 2 by a stamping process. The through hole a on the back plate 1() is located at the edge of the back plate 1〇. More specifically, the through hole 1 〇〇 a on the back plate 10 is located on the base 1 背 of the back plate 1 并 and adjacent to the side wall 102. The material that is detached from the substrate 1 is connected to the side wall 102 of the back plate 10 to form the extension portion 102b' under the locking hole 102a and the rim of the extension portion 102b is substantially the same as the through hole. The contours match. The stability of the backplane 1〇 structure can be enhanced by increasing the area of the side wall 1〇2 adjacent to the locking hole 102a by the above-described extension portion 1〇2b. In one embodiment, in order to provide sufficient structural strength of the backing plate 1 of the display device, the backing plate 10 may be made of sheet metal, but is not limited thereto. Please refer to FIG. 2B, FIG. 3 and FIG. Fig. 2B is a partial perspective view showing the backing plate 10 in Fig. 1, in which the cushioning member 2 is engaged with the through hole 100a.

As shown in FIG. 2B to FIG. 4, in the present embodiment, the buffer member 20 of the display device is adapted to engage the through hole l〇〇a on the substrate 100 of the back plate 10, whereby the light guide plate 14 is assembled to the back. The light guide plate 14 is positioned against the plate during the first step. Further, the buffer member 20 of the display device mainly includes the body 200 and the groove 200a. The groove 2〇〇a of the buffer member 2〇 is located on the body 2〇〇 and cooperates to receive the edge of the through hole l〇〇a. When the cushioning member 2 is assembled toward the through hole 1A, the body 200 of the cushioning member 20 is pressed by the edge of the through hole l〇〇a to be elastically deformed. Further, after the body 200 of the cushioning member 20 is continuously moved to accommodate the edge of the through hole 100a in the groove 2〇〇a, the body 200 of the cushioning member 2 can be elastically restored to engage the through hole 1〇〇a. As shown in Fig. 3, in the present embodiment, the cushioning member 2 of the display device may further include a guiding portion 200b. The guiding portion 200b of the cushioning member 20 is located on the body 200 and can be used to guide the edge of the through hole 100a when the cushioning member 2 is pressed toward the through hole 1A, so that the assembler can perform the assembly more smoothly. As shown in Figs. 3 and 4, in the present embodiment, the cushioning member 20 of the display device may further include a first abutting portion 2c. The first mitigating portion 200c of the cushioning member 2 is located on the body 200 and connected to the groove 2〇〇a. When the cushioning member 2 is engaged with the through hole l〇〇a, the first abutting portion 2〇〇c of the cushioning member 2〇 directly faces the light guiding unit 14, and is further guided during the assembly of the light guiding plate 14 to the backing plate 1〇.
