Description
Technical field
The utility model relates to TV domain, relates in particular to a kind of liquid crystal module and LCD TV thereof.
Background technology
In recent years, advantage such as the LED LCD TV is because of energy-conserving and environment-protective, and is in light weight, ultra-thin has occupied the share of market more than 80% gradually.From the beginning of this year, the LED LCD TV of narrow frame has also received the favor in market gradually.The width of LCD TV frame depends primarily on the width of inner liquid crystal module frame.Along with the development in LCD TV market, the frame of liquid crystal module also by initial 26mm up to narrowing down to present 9.9mm.From growth momentum, from now on more large scale will appear, the LED liquid crystal module of ultra narrow frame.
Referring to Fig. 1, LED liquid crystal module 50 is mainly assembled by metal front frame 10, Open-cell (liquid crystal panel) 20 and module backlight 30 three parts.Wherein, side entering type LED-backlit module 30 parts mainly comprise LED lamp bar 33, heat radiator 32, LGP 35, blooming piece 36, reflector plate 37, metal backing 34 and plastic cement center 31.For the narrow frame liquid crystal module 50 of LED, because the liquid crystal module 50 of same size because of its liquid crystal panel 20 viewing areas 70 size constancies, realizes frame narrowing so have only through dwindling liquid crystal module 50 profiles.The frame of liquid crystal module 50 is narrow more, and jaundice appears in incident side, and the risk of defectives such as light leak is big more.Simultaneously, in the module thinning, under the light-weighted trend, LGP 35 thickness of module internal are thinned to 4mm by original 6mm, till now 3mm, even 2.5mm again.LGP 35 thickness are thin more, and are just few more to the contribution of liquid crystal module 50 brightness.Therefore, the luminous power demand of 50 pairs of LED lamps of liquid crystal module is high more, and the heat of generation is also big more, and the distance between the LED lamp can not be too near.The LED lamp limited amount of arranging on the lamp bar substrate of same length.This just requires liquid crystal module 50 designs to improve the utilization factor of the light of LED lamp, and the light that the LED lamp is sent enters into the incidence surface of LGP 35 fully, and light is through LGP 35, and the reflection of blooming piece 36 and diffusion are evenly mixed.Light mixes even more, arrives 70 edges, liquid crystal panel 20 viewing areas and jaundice occurs, and the risk of defectives such as light leak is just more little.
Referring to Fig. 2, in the prior art, signal that can volume shipment than high-power LED lamp has WLED5630 and WLED6030.The width dimensions of corresponding light-emitting area is 3mm.With thick LGP 35 collocation of 3mm, need both complete contrapositions in center in theory, the LED lamp wiring could more get into LGP 35.In fact, the clearance D 1 that needs to reserve LGP 35 self expanded by heating is gone up in liquid crystal module 50 design, and size is big more, and clearance D 1 is big more.In addition, LED lamp self has lighting angle.So just exist a part of light can not get into LGP 35.Be refracted to viewing area 70 behind process blooming piece 36 end faces that this part light has, like light 2, the directly entering viewing area 70 from the gap between blooming piece 36 and the plastic cement center 31 that has is like light 1.Viewing area 70 bright dark inhomogeneous or light leak defectives have so just been caused.
In the prior art, in order to solve narrow frame liquid crystal module 50 incident side jaundice or light leak problem, the method that has now adopted has following two kinds:
Referring to Fig. 3, between the plastic cement center 31 incident side bottom surfaces and blooming piece 36 of liquid crystal module 50, attach black bumper rubber 38.Black bumper rubber 38 is used for absorbing the light that spills from the gap.Or the center that makes LED lamp bar 33 is lower than the numerical value D2 in LGP 35 incidence surface centers, if D2 is excessive, LED lamp part light can the loss down from LGP 35 bottom surfaces.Can make the loss amount that reduces light like this.
Generally, these two kinds of methods application that combines.But to a certain extent, between plastic cement center 31 and blooming piece 36, paste the method for black adhesive tape 38, can absorb light leak.But, can make the light inlet lateral deviation of liquid crystal module 50 dark like this, influence picture quality.In addition, blooming piece 36 expanded by heating receive the extruding of black adhesive tape 38.Can't unfold the local warpage that produces fully.Be prone to make liquid crystal module 50 pictures to produce high temperature WAVING defective like this.
Referring to Fig. 4, also there is certain limitation in the method that the center of LED lamp bar 33 is lower than LGP 35 incidence surface centers: the width dimensions of the LED lamp of LED lamp bar 33 can not be greater than the thickness of LGP 35.If adopt the more LGP 35 of minimal thickness, total some light of LED lamp light-emitting area can not get into LGP 35 like light 1 or light 2.The method is only applicable to undersized liquid crystal module 50.Liquid crystal module 50 sizes are big more, and the expansion space that LGP 35 needs self is just big more, and clearance D 1 is big more, and the LED lamp has lighting angle, and light losing increases relatively, and part light arrives viewing area 70 without LGP 35.The method is to metal backing 34, heat radiator 32, and the flatness of LED lamp bar 33 structural members, angularity is had relatively high expectations, and needs to guarantee to produce line operation assembling and want strict management and control.Size is big more, and the specification of structural member needs to amplify, and transportation; Be prone to local deformation in the assembling; There is the space part between LGP 35 and the reflector plate 37, causes the part light of partial LED lamp bars 33 in the liquid crystal module 50, passes and causes viewing area 70 to leak lamp light leak defectives like light 3, light 4 or from blooming piece 36 xsects; Or, pass under the site, LGP 35 bottom surface again and cause viewing area 70 jaundice defectives earlier through reflector plate 37 reflections.
Can know that to sum up existing liquid crystal module obviously exists inconvenience and defective, so be necessary to improve on reality is used.
