Fig. 3 illustrates another schematic perspective view of the display unit of Fig. 1.This mandatory declaration be, for convenience of description for the purpose of, the display unit 200 not shown partial component (seeing for details following) of Fig. 3.Please refer to Fig. 2 and Fig. 3, these cooling devices 230 for example are axial flow fan (axial fan), are disposed in the housing 210 and are positioned on the non-display area 224.Each cooling device 230 has the air intake vent 232 corresponding to second opening 214 of housing 210.
Fig. 4 illustrates the perspective exploded view of the dust guard of Fig. 2.Please refer to Fig. 2, Fig. 3 and Fig. 4, dust guard 240 comprises body 242, lid 244 and dust guard 246 (the not shown dust guard 246 of Fig. 3).Dust guard 246 (for example being dustproof sheet) is disposed between body 242 and the lid 244.Body 242 is disposed in the housing 210 and is positioned on the non-display area 224.Body 242 has the first perforate 242a of a plurality of air intake vents 232 corresponding to these cooling devices 230.In the present embodiment, body 242 comprises first 242b of window frame portion and annulus 242c.These first perforates 242a is formed at first 242b of window frame portion, and first 242b of window frame portion connects annulus 242c, and these cooling devices 230 are positioned at body 242.
The lid 244 of dust guard 240 is disposed at body 242, and has a plurality of second perforate 244a.Second opening 214 of housing 210 exposes these second perforates 244a.In the present embodiment, lid 244 comprises second 244b of window frame portion and two side plate 244c respect to one another.These second perforates 244a is formed at second 244b of window frame portion, and second 244b of window frame portion connects these side plates 244c.Each side plate 244c is slidedly arranged on the annulus 242c of body 242.Particularly, each side plate 244c of lid 244 has slide rail (slide) S, and the annulus 242c of body 242 has two projectioies (protrusion) P.These protruding P pass these slide rails S respectively, and two fixtures 248 (for example screw) are individually fixed in these protruding P, make each side plate 244c be slidedly arranged on the annulus 242c of body 242.In addition, second 244b of window frame portion is fixed in first 242b of window frame portion by other a plurality of fixtures 249 (for example screw).
Fig. 5 illustrates the schematic side view of the display unit of Fig. 1.This mandatory declaration be, for convenience of description for the purpose of, the not shown dust guard 246 of the display unit of Fig. 5.Please refer to Fig. 3, Fig. 4 and Fig. 5, the part at least wherein of each second perforate 244a and these first perforates 242a is overlapping.Particularly, body 242 also has surperficial 242d.These first perforates 242a is formed on the surperficial 242d, and each first perforate 242a is a rectangle opening, and each second perforate 244a is a rectangle opening.Orthographic projection and these first perforate 242a common formation a plurality of staggered holes (interlaced hole) I of these second perforates 244a on surperficial 242d, and the beeline d of relative two edges I1, the I2 of each staggered hole I is less than 12 millimeters.Therefore, user's finger can't arbitrarily stretch into the inside of display unit 200 via these staggered hole I, and the finger of avoiding the user that makes the display unit 200 of present embodiment meet safety standard arbitrarily stretches into the safety requirements of the inside of display unit 200.
Below make an explanation for the operation of these cooling devices 230 of present embodiment.Fig. 6 illustrates the generalized section of the dust guard of Fig. 5 along line I-I '.Please refer to Fig. 3, Fig. 4 and Fig. 6, each cooling device 230 is suitable for producing air-flow 234.These first perforates 242a of body 242 of dust guard 246, dust guard 240 of these second perforates 244a, dust guard 240 of lid 244 that each air-flow 234 for example flows through second opening, 214 (see figure 2)s, the dust guard 240 of housing in order flows to corresponding cooling device 230 with air intake vent 232 (see figure 2)s of corresponding cooling device 230 inside is to dispel the heat for a plurality of electronic components of display unit 200 (visible Fig. 2, but indicate).
Because dust guard 246 is disposed between body 242 and the lid 244, and air-flow 234 enters the inside of corresponding cooling device 230 with corresponding air intake vent 232 through second opening 214, these second perforates 244a, dust guard 246, these first perforates 242a, so the display unit 200 of present embodiment can effectively prevent extraneous foreign matter and drive via air-flow 234 and enter the inside of display unit 200, make the display unit 200 of embodiments of the invention meet the dustproof requirement of safety standard.In addition, because the lid 244 of dust guard 240 is disposed at the body 242 of dust guard 240, the part at least wherein of these first perforates 242a of each second perforate 244a of lid 244 and body 242 is overlapping, and the dust guard 246 with thickness t is disposed between body 242 and the lid 244, so air-flow 234 can enter the inside of display unit 200 perpendicular to the path of the orientation of these second perforates 244a and the path that favours the orientation of these second perforates 244a.Therefore, the percent opening of the display unit 200 of present embodiment is higher, and then promotes the air quantity of going into of air-flow.
Below change dust guard 246 for the dust guard 240 of present embodiment process describe.The dust guard that Fig. 7 illustrates the display unit of present embodiment is changed the schematic perspective view of dust guard.Please refer to Fig. 4 and Fig. 7, in the present embodiment, when the user wanted to change dust guard 246, the user at first dismantled these fixtures 249 that second 244b of window frame portion are fixed in first 242b of window frame portion.Then, second 244b of window frame portion of the lid 244 of dust guard 240 carries out with respect to body 242 by these side plates 244c, makes lid 244 present the state of unlatching with respect to body 242.Then, the dust guard of having used 246 is taken out to change another dust guard (not shown).Therefore, the mode of the replacing dust guard 246 of the dust guard 240 of present embodiment is comparatively simple and easy.
In sum, the display unit of the above embodiment of the present invention has following one or part or all of advantage:
One, because dust guard has dust guard, drive via air-flow and enter the inside of display unit so the display unit of present embodiment can effectively prevent extraneous foreign matter, make the display unit of embodiments of the invention meet the dustproof requirement of safety standard.
Two, because the lid of dust guard is disposed at the body of dust guard, at least wherein the part of these first perforates of each of lid second perforate and body is overlapping, and dust guard is disposed between body and the lid, so the percent opening of the display unit of embodiments of the invention is higher, and then promote the air quantity of going into of air-flow.
Three, these second perforates of the lid of dust guard and these first perforates form these staggered holes jointly, and the beeline of the relative two edges in each staggered hole is less than 12 millimeters.Therefore, user's finger can't arbitrarily stretch into the inside of display unit via these staggered holes, and the finger of avoiding the user that makes the display unit of embodiments of the invention meet safety standard arbitrarily stretches into the safety requirements of the inside of display unit.
Four, since dust guard can be by disassembling fixture opening cover changing dust guard, so that the dust guard of embodiments of the invention is changed the mode of dust guard is comparatively simple and easy.
Though it is as above open that the present invention has carried out with embodiment; right its is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; can do a little change and modification, so protection scope of the present invention is when being as the criterion with the scope that claims were defined.Arbitrary embodiment of the present invention in addition or claim need not to realize whole purpose disclosed in this invention or advantage or characteristics.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not to be used for limiting interest field of the present invention.
