Description
Technical field
The present invention relates to a kind of backlight liquid crystal display module that is used for, be used for the backlight module of pointolite relevant for a kind of especially as backlight.
Background technology
Backlight module (Back light module) is panel of LCD (Liquid crystal displaypanel, LCD panel) one of key part and component, because liquid crystal itself is not luminous, the function of backlight module promptly is well-off brightness and the light source that is evenly distributed, so that the panel of LCD back light to be provided.Panel of LCD now has been widely used in the electronic product of tool growth potentiality such as monitor, notebook computer, digital camera and projector, especially with large scales such as notebook computer and LCD monitor panel demand maximum, also therefore grow up also strong day by day for the backlight module demand.
Backlight module is divided into side-light type and two kinds of forms of straight-down negative, wherein, direct type backlight module its mainly assemble by assemblies such as light source (for example pointolite, cathode fluorescent tube, external electrode fluorescent lamp pipe, flat luminous fluorescent tube or other), reflector plate (Reflector), diffuser plate (Diffusion plate), diffusion sheet (Diffusion film), brightening piece (Brightness Enhancement Film) and frameworks.After the light that light source produced enters diffuser plate, can guide the light source of injecting it is scattered in uniform surface light source, the reflector plate that is arranged in diffuser plate one side can prevent that light source from leaking outside with light source towards the light reflected back diffuser plate that the reflector plate direction is produced, to increase the service efficiency of light.The light that is penetrated by diffuser plate, is incident to light in the liquid crystal panel after the brightness and uniformity coefficient of raising light source more again through the equal light action of diffusion sheet and the enhanced shine of brightening piece.
See also Fig. 1, Fig. 1 is the diagrammatic cross-section of the backlight module 10 of prior art.Backlight module 10 comprises a framework 12, a substrate 14, a reflector plate 16, plurality of points light source 18 and a blooming piece 20.Carry plurality of points light source 18 on the substrate 14.Reflector plate 16 is positioned on the substrate 14, is used for the light that reflection spot light source 18 produces.20 of blooming pieces are arranged on the reflector plate 16.Elements such as framework 12 bearing substrates 14, reflector plate 16 and plurality of points light source 18 are to avoid extraneous effect of dust.Substrate 14 sees through retaining element 26 lockings on framework 12.Traditionally, retaining element 26 can be a screw, but the nut of screw can't reflection ray, so reflector plate 16 covers screw usually.
See also Fig. 1 and Fig. 2, Fig. 2 is the partial top view of existing reflector plate 16.Reflector plate 16 is positioned on the substrate 14, so it must offer plurality of openings 22, make that the pointolite 18 that is arranged on the substrate 14 is worn and mistake, only illustrate four row of openings 22 at this, but be actually points of engagement light source 18, the quantity of opening 22 will be not limited to the quantity that Fig. 2 draws.Because more than up to a hundred, the elasticity when installing for increasing can be provided with bent regional 24 around the plurality of openings 22 of traditional reflector plate 14 to the number of pointolite 18 easily.When reflector plate 16 passes plurality of points light source 18 and is positioned on the substrate 14, bent regional 24 can perks, and plurality of points light source 18 is positioned in opening 22 places between bent regional 24.Quick assembling no doubt is convenient in the design of such reflector plate 16, yet the uneven problem of reflection takes place bent regional 24 meetings around pointolite 18, and then causes display quality flaw to occur.
