Description
Technical field
The present invention is about a kind of display unit and backlight module thereof, especially in regard to a kind of liquid crystal indicator and side light type back light module thereof.
Background technology
Owing to the development of Display Technique, traditional cathode-ray picture tube display unit is replaced by liquid crystal indicator gradually in recent years.Wherein, because liquid crystal can't self luminous characteristic, in liquid crystal indicator, must utilize backlight module as its backlight.
Please refer to shown in Figure 1ly, it is a kind of fragmentary cross-sectional view of existing liquid crystal indicator 1.Liquid crystal indicator 1 comprises display panels 11, side light type back light module 12 and housing 13.Side light type back light module 12 has framework 121, backboard 122, cathode fluorescent tube 123, LGP 124, lampshade 125 and optical diaphragm group 126.
Framework 121 is used for support bearing display panels 11, and can lightguide plate fixing 124 and the position of optical diaphragm group 126.In addition, framework 121 can make between display panels 11 and the side light type back light module 12 to have apart from G, so that the light that is penetrated by LGP 124 can have enough light mixing distance, and is incident to display panels 11 equably.
Cathode fluorescent tube 123 is arranged in the lampshade 125, and cathode fluorescent tube 123 and lampshade 125 then are arranged at a side of LGP 124, and 124 of LGPs are arranged on the backboard 122.The light reflection that reflecting surface by lampshade 125 can be sent cathode fluorescent tube 123 enters LGP 124, optical diaphragm group 126 then is arranged at the exiting surface of LGP 124 and fixes by framework 121, is used for making the bright dipping diffusion of side light type back light module 12 even.
In side light type back light module 12, lampshade more than 125 utilizes metal material to stick reflecting material, makes by the punch forming mode again.Yet owing to be subjected to the restriction of die size, side light type back light module 12 that only can corresponding single size is made, and as the side light type back light module 12 of corresponding different size, must utilize the mould of different size to make by stamping forming lampshade 125.And, stamping forming technology is complicated (for example technology such as blanking, bending) comparatively, and the defective products in the manufacturing process reclaims system again, technology also comparatively complicated technologies such as (for example metal fusion, casting) again systems, these all can cause the reduction of process efficiency of side light type back light module 12 and the raising of cost of manufacture.
In addition, the framework more than 121 in the side light type back light module 12 utilizes the plastic material ejection formation and makes, thus need purchase another mould again, and cause production cost to increase.In addition, housing 13 must utilize instrument (for example screwdriver) to carry out sealed fixing with backboard 122, so not only easily cause the packaging efficiency of liquid crystal indicator 1 poor, and in assembling process, also easily produce artificial error, and then cause the qualification rate of product to reduce.
Therefore, how to provide a kind of and can reduce cost and improve liquid crystal indicator and the side light type back light module thereof of making packaging efficiency, become one of important topic gradually.
Summary of the invention
Because above-mentioned problem, purpose of the present invention can reduce cost and improve liquid crystal indicator and the side light type back light module thereof of making packaging efficiency for providing a kind of.
For reaching above-mentioned purpose, a kind of side light type back light module according to the present invention comprises LGP, at least one luminescence component and at least one crowded type assembly.Luminescence component is arranged at a side of LGP, squeezes the type assembly and has holding part and supporting part, and luminescence component is arranged in the holding part, the distance between supporting part definition LGP and the display panels.
For reaching above-mentioned purpose, a kind of liquid crystal indicator according to the present invention comprises display panels and side light type back light module.Side light type back light module is connected with display panels, have LGP, at least one luminescence component and individual one squeeze the type assembly at least, luminescence component is arranged at a side of LGP, squeeze the type assembly and have holding part and supporting part, luminescence component is arranged in the holding part, the distance between supporting part definition LGP and the display panels.
In an embodiment of the present invention, the crowded type assembly that has of side light type back light module is formed in one.
From the above, have at least one crowded type assembly according to liquid crystal indicator of the present invention and side light type back light module thereof and have holding part and supporting part simultaneously, and luminescence component is arranged in the holding part, supporting part then defines the distance between LGP and the display panels, and can carry display panels.Wherein, squeezing the type assembly can be formed in one.Therefore, the side light type back light module of corresponding different size, can directly cut the crowded type assembly of different length, and the more stamping forming technology of the technology of extrusion forming is simpler and easy, and the recyclable system again of the crowded type assembly of defective products in the manufacturing process, therefore side light type back light module of the present invention can improve process efficiency effectively and reduce cost of manufacture.In addition, crowded type assembly of the present invention can be integrated the lampshade of existing side light type back light module and the function of framework, therefore, not only can carry out process integration with the raising make efficiency, and reduce assembled components quantity and also can improve packaging efficiency.And side light type back light module of the present invention also can be applicable in the liquid crystal indicator, with cost of manufacture that reduces liquid crystal indicator and the making packaging efficiency that improves liquid crystal indicator.
