First by 6 upside down of glue frame when the module group assembling of the utility model, then put through the inversion of above-mentioned diaphragm overall structure
Enter into the installation position limiting structure at 6 back side of glue frame, finally engages the lower iron frame 1 for being mounted with side entering type light source 7 with glue frame 6.Card
Conjunction mode can specifically be arranged between lower iron frame 1 and glue frame 6 and match by fastening on the outside of the inside of lower iron frame 1 and glue frame 6
Buckle structure realize, fixed so that glue frame 6 and lower iron frame 1 can together press diaphragm structure.
Refering to fig. 1, the retroreflective sheeting 2 is fixed below guide-lighting film 3, can specifically be entered in retroreflective sheeting 2 except side
Side elevation, the lateral surface of the inner surface of each side elevation and guide-lighting film 3 is arranged in the other three side outside 7 place side of formula light source
Pass through two-sided glue sticking.
Refering to fig. 1, in order to improve the positive brightness of mould group, settable two diaphragms 5 that add lustre to, including 51 He of diaphragm of above adding lustre to
Under add lustre to diaphragm 52, it is described on the setting of diaphragm 51 that adds lustre to add lustre on diaphragm 52 under.Add lustre to diaphragm 51 and lower increasing on described
Light diaphragm 52 can select prismatic lens, and on add lustre to diaphragm 51 and under add lustre to diaphragm 52 prism direction it is perpendicular.
Refering to fig. 1, in order to preferably fix astigmatism diaphragm 4, on add lustre to diaphragm 51 and under add lustre to diaphragm 52, can be by astigmatism
Diaphragm 4, on add lustre to diaphragm 51 and under the diaphragm 52 that adds lustre to be pasted on guide-lighting film 3, be provided with first on the outside of the astigmatism diaphragm 4
Opening 41 is provided with the second opening 521, first opening 41 and the second 521 positions of opening on the outside of the diaphragm 52 that adds lustre under described
Corresponding, 41 to the second opening 521 of the first opening is big, thus under add lustre to diaphragm 52 can from the first opening 41 with leaded light film
3 contacts, equally, the diaphragm 51 that above adds lustre to can contact from the second opening 521 with guide-lighting film 3, thus the astigmatism diaphragm 4,
Under add lustre to diaphragm 52 and the diaphragm 51 that above adds lustre to can be pasted on guide-lighting film 3 by first double-sided adhesive 8, that is, save
Material, but it is convenient for assembly.
Refering to fig. 1, in order to facilitate the fixation for showing equipment when the use of mould group with the installation of other display units or entirely, institute
State lower 1 back side of iron frame and be provided with fixed bolt 11, can by fixed bolt 11 by by the utility model module group assembling at it is aobvious
Show that device is fixed on end product.
Refering to fig. 1, the inside in the glue frame 6 is provided with concave station 61, is pasted with the second double-sided adhesive on the concave station 61
611, to provide the erecting bed of liquid-crystalline glasses, and LCD mould group is fixed by the second double-sided adhesive 611.In the glue frame 6
It is covered with protective film 9, protective film 9 is covered on entire above the diaphragm 51 that adds lustre to, plays the role of temporary protective film piece, avoid ash
Dirt etc. pollutes diaphragm, and whens subsequent installation liquid-crystalline glasses tears protective film 9.
