Fig. 3 A and Fig. 3 B illustrates the schematic diagram in the corner of supporting part in one embodiment of the invention.Fig. 4 illustrates the upward view in the corner of the supporting part in one embodiment of the invention.For convenience of description, add blooming piece 120 at Fig. 3 A and Fig. 3 B to illustrate.Referring to Fig. 3 A, Fig. 3 B and Fig. 4, the first surface 200 in the corner 114 of framework 110 is right angle, second face 220 is arc angle, and arc angle is projected on the position of first surface 200 between right angle and the outer rim 210 of supporting part 113, that is, first surface 200 is right angle in corner 114, and the second face 220 is arc angle in corner 114, and the edge of arc angle in first surface 200 projected position not with the imbricate at right angle.
Further illustrate, corner 114 has the first side wall 240, second sidewall 250 and skirt section 270, and the first side wall 240, second sidewall 250 and skirt section 270 are between first surface 200 and the second face 220, the first side wall 240 connects with the second sidewall 250, the first side wall 240 has the first limit 241 and Second Edge 242, first limit 241 is connected with first surface 200 and Second Edge 242 is connected with the upper limb in skirt section 270, second sidewall 250 has the 3rd limit 251 and the 4th limit 252, 3rd limit 251 is connected with first surface 200 and the 4th limit 252 is connected with the upper limb in skirt section 270, and the lower edge in skirt section 270 is connected with the second face 220.In other words, first surface 200 is orthogonal the formed right-angle corner in the first limit 241 and the 3rd limit 251 in corner 114, and Second Edge 242 and the 4th limit 252 are also the upper limb in skirt section 270.
The Second Edge 242 of the first side wall 240 is curve, Second Edge 242 has the first section I1, the first horizontal segment 2421 and the first bending segment 2422, first section I1 is between the first horizontal segment 2421 and the first bending segment 2422, being the first bending segment 2422 from the first section I1 to the first side wall 240 and the second sidewall 250 joint, is the first horizontal segment 2421 from the first section I1 away from the first side wall 240 and the second sidewall 250 joint.First section I1 is the terminal of the first bending segment 2422, and is the starting point of the first horizontal segment 2421, and the first horizontal segment 2421 and the first bending segment 2422 are tangential on the first section I1.In addition, on the first horizontal segment 2421 of the Second Edge 242 of the first side wall 240, the beeline on any point to the first limit 241 is isometric.On first bending segment 2422, the beeline on any point to the first limit 241 is Length discrepancy, and more increases gradually close to the beeline of the first side wall 240 and the second sidewall 250 joint.Similarly, 4th limit 252 of the second sidewall 250 of supporting part 113 is curve, 4th limit 252 has the second section I2, the second horizontal segment 2521 and the second bending segment 2522, second section I2 is between the second horizontal segment 2521 and this second bending segment 2522, being the second bending segment 2522 from the second section I2 to the first side wall 240 and the second sidewall 250 joint, is the second horizontal segment 2521 from the second section I2 away from the first side wall 240 and the second sidewall 250 joint.Second section I2 is the terminal of the second bending segment 2522, and is the starting point of the second horizontal segment 2521, and the second horizontal segment 2521 and the second bending segment 2522 are tangential on the second section I2.In addition, on second horizontal segment 2521 on the 4th limit 252, any point is isometric to the beeline on the 3rd limit 251, on second bending segment 2522 on the 4th limit 252 of the second sidewall 250, any point is Length discrepancy to the beeline on the 3rd limit 251, and more increases gradually close to the beeline of the first side wall 240 and the second sidewall 250 joint.It should be noted that, first bending segment 2422 of the Second Edge 242 of the first side wall 240 bends to the direction of the first side wall 240 and the second sidewall 250 joint from the first section I1, and second bending segment 2522 on the 4th limit 252 of the second sidewall 250 bends to the direction of the first side wall 240 and the second sidewall 250 joint from the second section I2, the first bending segment 2422 and the second bending segment 2522 is made to intersect at one first end points P1.
The lower edge in skirt section 270 is connected with the second face 220 and corresponds to the first side wall 240 and the second sidewall 250 joint is a circular arc 273, and connect with the first skirt 271 and the second skirt 272 respectively in the both sides of circular arc 273, and the virtual extended line of the first skirt 271 and the second skirt 272 extends toward the first side wall 240 and the second sidewall 250 joint, as shown in Figure 4, can intersect at a second virtual end points P2, the position of the second end points P2 will between circular arc 273 and the outer rim 210 of supporting part 113 on the second face 220.It can thus be appreciated that if the second face 220 is right angle in corner 114, the position at its right angle is namely at virtual end points second end points P2 place.In stereochemical structure, circular arc 273 is essentially a part of sphere with the first side wall 240 and the second sidewall 250 joint, and this spherical calotte is projecting inward toward supporting part 113 in the first end points P1 place, as shown in Fig. 3 A and Fig. 4, blooming piece 120 cuts a rescinded angle, in order to get out of the way connector 151, blooming piece 120 and connector 151 is avoided to interfere.What the structure of this spherical calotte can hide the rescinded angle of blooming piece 120 cuts edge 122, prevents from causing bright line because cutting edge 122 optically focused.In other words, blooming piece 120 rescinded angle cut the projected position of edge 122 on the second face 220 between arc angle and the outer rim 210 of supporting part 113.
It should be noted that, mid point P4 on circular arc 273 is nearer to the distance of virtual end points second end points P2, cover the rescinded angle of blooming piece 120 cut edge 122 to produce bright line effect poorer, otherwise it is then better, but the route still can advanced according to light path adjustment adjusts with the type of display unit, to reach the effect that the best covers light leak, improve the display quality of display unit.
In addition, the design in the corner 114 of this framework 110 is not limited to the corner corresponding to the connector 151 arranging light source module 150, also can be arranged at other corner of framework 110.In other words, also can be the design that a more than corner is invented for this reason, singly see the demand of user and determine.Above execution mode also can be used in the execution mode of not shown directly-down light source module.
The present invention is described by above-mentioned related embodiment, but above-described embodiment is only enforcement example of the present invention.Must it is noted that the embodiment disclosed limit the scope of the invention.On the contrary, be contained in the spirit of claims and the amendment of scope and equalization to arrange and be all included within the scope of the present invention.
