Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 and Fig. 2, display device 100 comprises housing 10, display panel 20, backlight module 30 and radiator structure 40.Display panel 20, backlight module 30 and radiator structure 40 all fix with housing 10.Radiator structure 40 is between housing 10 and backlight module 30.The heat produced when radiator structure 40 is for absorbing backlight module 30 luminescence is also distributed to housing 10 outside, because being heated, deformation occurs to prevent housing 10.In the present embodiment, display device 100 is liquid crystal display.
Housing 10 is made up of plastic material, it back cover 12 comprising front frame 11 and fix with front frame 11 separably.Front frame 11 is provided with opening 111, exposes to housing 10 to make display panel 20 by opening 111.
Please refer to Fig. 3, back cover 12 is provided with some first through holes 121 and some second through holes 122.The inside surface 123 that back cover 12 is relative with front frame 11 is provided with and organizes fastener 124 and many stiffening rib protruded 125 more.Fastener 124 comprises two intervals and symmetrically arranged snap fit 1241,1242.Fastener 124 is for fixing radiator structure 40.Many the interlaced settings of stiffening rib 125.
Refer to Fig. 4, backlight module 30 is for providing backlight for display panel 20.Backlight module 30 comprises reflecting plate 31 and some lamp bars 32.Reflecting plate 31 is provided with multiple third through-hole 311.Reflecting plate 31 and display panel 20 are oppositely arranged.Some lamp bars 32 are arranged at reflecting plate 31 side opposing with display panel 20.Arranged in parallel between some lamp bars 32, and interval between adjacent lamp bar 32 is equal.The substrate 321 that lamp bar 32 comprises strip and the multiple pointolites 322 be arranged on substrate 321.The plurality of pointolite 322 is positioned at side relative with reflecting plate 31 on substrate 321, and spacing between consecutive point light source 322 is equal.The plurality of pointolite 322 and multiple third through-holes 311 one_to_one corresponding on reflecting plate 31.Pointolite 322 can be luminous towards display panel 20 through corresponding third through-hole 311.The light that pointolite 322 sends becomes the backlight of display panel 20 after optical texture (such as diffuser plate, brightening piece etc., figure does not show) process.In the present embodiment, pointolite 322 is LED.
Radiator structure 40 is made up of transcalent metal or alloy material.Radiator structure 40 comprises some first radiating piece 41 corresponding with above-mentioned some lamp bars 32 and some second radiating pieces 42.First radiating piece 41 comprises body 411 and some radiating parts 412 be arranged on body 411.Body 411 comprises base plate 4111 side plate relative with two 4112.Two side plates 4112 are formed by the surperficial Vertical dimension extension that base plate 4111 is relative with lamp bar 32.Side plate 4112 for improving the intensity of the first radiating piece 41, to reduce the probability of the first radiating piece 41 deformation.Base plate 4111 and two side plates 4112 form accepting groove 4113 jointly.Accepting groove 4113 is for accommodating the substrate 321 of lamp bar 32.Base plate 4111 is provided with screw (not shown), in the mode by screw locking, substrate 321 is fixed in accepting groove 4113.Base plate 4111 and substrate 321 close contact, with the heat produced when more effectively absorption point light source 322 is luminous.Radiating part 412 is hollow cylinder, and it is formed by the surperficial Vertical dimension extension that base plate 4111 and lamp bar 32 are opposing.This some radiating part 412 and some first through hole 121 one_to_one corresponding on back cover 12.Radiating part 412 can expose to housing 10 through the first corresponding through hole 121.The structure of the second radiating piece 42 is roughly the same with the first radiating piece 41.Second radiating piece 42 comprises body 421.The side plate 4212 that body 421 has base plate 4211, two of being arranged on base plate 4211 are relative and the accepting groove 4213 jointly formed by the side plate 4212 that base plate 4211 is relative with two.
Refer to Fig. 5, during assembling display device 100, first, some lamp bars 32 are individually fixed in some accepting grooves 4113,4213 of radiator structure 40.Secondly, to be fixed with fastener 124 between two snap fits 1241,1242 radiator structure 40 being held on fastener 124, thus lamp bar 32 and radiator structure 40 are fixed with back cover 12.Now, the some radiating parts 412 on the second radiating piece 42 are each passed through the first corresponding through hole 121 and expose to housing 10, can be used as the suspension strut structure of display device 100.Base plate 4111,4211 is resisted against on multiple stiffening rib 125, and radiator structure 40 is kept at a certain distance away with the inside surface 123 of back cover 12.Then, reflecting plate 31 is fixed on back cover 12, and makes pointolite 322 through corresponding third through-hole 311.Finally, display panel 20 and front frame 11 are fixed, and front frame 11 is fixed on back cover 12.So, then the assembling of display device 100 is completed.
When display device 100 works, pointolite 322 luminescence thinks that display panel 20 provides backlight.Because the inside surface 123 of radiator structure 40 with back cover 12 keeps at a certain distance away, and radiator structure 40 can absorb the heat produced when also conducting spots light source 322 works, this heat that pointolite 322 is produced is not concentrated in areas adjacent corresponding with pointolite 322 on back cover 12, so, then avoid back cover 12 local overheating and produce deformation.It is outside that the partial heat that pointolite 322 produces is distributed to housing 10 via the radiating part 412 exposing to housing 10, and it is outside that partial heat is distributed to housing 10 by the second through hole 122.Make the temperature of housing 10 inside reduce like this, reduce housing 10 and be heated and the probability of deformation occurs.The hollow-core construction of radiating part 412 can make radiating part 412 increase with the contact area of air, improves radiating efficiency.In addition, because radiator structure 40 is fixed by fastener 124 and back cover 12, improve the intensity of back cover 12, further reduce back cover 12 and be heated and the probability of deformation occurs.Above-mentioned radiator structure 40 has the effect of the intensity of heat radiation and reinforcement back cover 12 simultaneously, reduce the probability that deformation occurs because being heated back cover 12, thus reduce the probability of lamp bar 32 along with back cover 12 together deformation, and then improve the light-emitting uniformity of backlight module 30.
Those skilled in the art will be appreciated that; above embodiment is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the suitable change do above embodiment and change all drop within the scope of protection of present invention.
