Description

A reflective sheet

The present invention relates to a reflective sheet; in particular, the present invention relates to a reflective sheet for use in a display module.

Generally, the flaps around the reflective sheet of the display device need to be fixed and incorporated into the backlight module. The flaps and the flaps of the conventional reflective sheet are fixed by double-sided tape or tape. However, in the process of applying the glue, the gap between the flaps may be excessive due to human factors. This will directly affect the light quality of the display panel. For example, it is easy to have a shadow at a position close to the corner of the display panel. In order to solve the problem of light distribution derived from the glue application process, the conventional method is to increase the number of LEDs at the corners to improve the brightness at the corners. But using this method will increase production costs.

In addition, the structural tightness of the double-sided tape or tape is insufficient. In order to solve this problem, the conventional method is to add double-sided tape or tape between the wings to further strengthen the attachment. However, this practice not only increases material costs, but also increases assembly time. As apparent from the above description, the structure of the conventional reflection sheet still needs to be improved.

An object of the present invention is to provide a reflection sheet which stabilizes the structure of the combined reflection sheet and reduces the error of the bonding process.

An object of the present invention is to provide a reflective sheet which can improve the backlight uniformity of the display.

The reflective sheet includes a first wing that connects the first side of the bottom plate and a second wing that connects the second side of the bottom plate. The first side and the second side intersect at a corner. The first wing and the second wing are respectively turned up with the first side and the second side as a fold line. The first wing has a first connecting edge extending from the corner, and the second wing has a second connecting edge extending from the corner. The connecting plate extends from the first connecting side and has a tongue formed thereon. The tongue has a free end facing the first connecting edge. A slot is formed in the second wing. When the first wing and the second wing are respectively turned up on the same side of the bottom plate, the connecting plate is overlapped with the second wing, the first connecting edge is aligned with the second connecting edge, and the tongue extends into the slot for positioning First wing and second wing.

Next, as shown in FIG. 2B, the connecting plate 15 is turned to the second flap 12 in the direction of the arrow. Viewed from another angle, as shown in the outer side view of FIG. 2C, the connecting plate 15 is turned to the second wing 12 in the direction of the arrow, and the connecting plate 15 is superposed on the outside of the second wing 12 (ie, laminated to the second The flap is opposite to one of the turned-up directions). At this time, the tongue piece 16 is rotated toward the second flap 12 with the connecting plate 15.

As shown in FIG. 2D, the connecting plate 15 is superposed on the outside of the second flap 12 (the position of the connecting plate is shown by a broken line). The tongue 16 extends into the slot 17 to position the first flap 11 and the second flap 12. When the tongue 16 projects into the slot 17, the slit 167 is parallel to the slot 17. In addition, as shown in FIG. 2C and FIG. 2D, when the connecting plate 15 is superposed on the second wing 12, the second cutting edge 152 and the second wing 12 are opposite to the top edge 125 of the second side 102. The combined reflection sheet 1 as a whole is shown in Fig. 2E, and the first flap 11 and the second flap 12 can be positioned by the tongue. The positioning can be separately performed in the same manner as the second flap 12 and the third flap 13, the third flap 13 and the fourth flap 14, and the fourth flap 14 and the first flap 11.

It should be added that in the embodiment shown in FIGS. 2A to 2C, the slot 17 is substantially Extending along the second connecting edge 12a, the free end 161 of the tongue 16 is parallel to the first connecting edge 11a. Thereby, after the first wing 11 and the second wing 12 are folded up to align the first connecting edge 101 and the second connecting edge 102, the tongue 16 can smoothly extend into the slot when the second wing 12 is folded. 17 in. However, not limited thereto, the distance between the tongue 16 and the first connecting side 11a and the angle between the extending direction of the free end and the first connecting side 11a (for example, the free end 161 is parallel to the first connecting side) may be visible to the slot 17. The distance from the second connecting side 12a and the angle between the slot extending direction and the second connecting side 12a (for example, the slot 17 is parallel to the second connecting side 12a) are adjusted. In general, the tongue and the slot are used to stabilize the structure of the combined reflective sheet, thereby reducing the error of the bonding process. At the same time, the reflective sheet of the present invention reduces the gap between the reflective sheet by the combination of the tongue and the slot to avoid the occurrence of dark bands in the four corners of the display panel.
