Detailed description of the invention

For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is The a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.

Should be appreciated that the term " first " in description and claims of this specification and above-mentioned accompanying drawing, " second ", " the 3rd " etc. are for distinguishing similar object, without being used for describing specific order or precedence.Should be appreciated that so Use data can exchange in the appropriate case, such as can be given in illustrating according to embodiments of the present invention or describing those with Outer order is implemented.Additionally, term " includes " and " having " and their any deformation, it is intended that cover but non-exclusive Comprise, such as, contain the product of a series of assembly or equipment is not necessarily limited to those assemblies of clearly listing, but can include That the most clearly list or for intrinsic other assembly of these products or equipment.

The light source assembly that the present embodiments relate to can use as arbitrary source, it is also possible to is suitable for display and provides the back of the body In arbitrary display terminal of light, such as, go for LCD TV, mobile phone, panel computer, PDA(Personal Digital Assistant, personal digital assistant), POS(Point of Sales, point-of-sale terminal), vehicle-mounted computer etc. have aobvious The equipment of display screen, the form of the embodiment of the present invention terminal unit to being applicable to does not limits.

As stated in the Background Art in correlation technique, three primary light source colour gamut coverage is by the centre wavelength institute of three bases luminescences Surrounding what triangle area determined at coordinate, therefore, light source is once prepare, and the covering gamut range of this light source determines, And in the related, in order to improve the gamut range of light source, basic resolving ideas is to change fluorescent material, such as employing amount Son point material etc. so that the color of primary lights is purer, it may be assumed that make its in FIG vertex of a triangle outwards include, such as in Fig. 1 in Between triangle 1 use fluorescent material stimulated luminescence to obtain gamut range, triangle 3 uses quanta point material stimulated luminescence to obtain color Territory scope.Therefore, once light source selects to determine that material and preparation complete, and the colour gamut coverage of this light source determines, in relevant skill Art cannot improve gamut range further.

It is different from correlation technique, in the application solves the thinking of gamut problem, in multiple primary colours luminous sources extremely The centre wavelength of a rare primary colours luminous source is variable, and wherein cardiac wave length is along with needs change, such that making is three primary light source In composition color mixing light source, constitute the face of the polygon (at least four limits) that the multiple summit of colour gamut coverage of this color mixing light source surrounds Long-pending, it is clear that territory, polygonal footprint area is greater than triangle area.

On the basis of the invention described above basic ideas, the provided light source assembly of the embodiment of the present invention and liquid crystal indicator, Aim to solve the problem that and the as above correlation technique of prior art exists technical problem, thus reach to improve further the colour gamut of display device The purpose of indication range.

With specifically embodiment, technical scheme is described in detail below.These concrete enforcements below Example can be combined with each other, and may repeat no more in some embodiment for same or analogous concept or process.

The structural representation of the light source assembly embodiment one that Fig. 2 provides for the embodiment of the present invention.As in figure 2 it is shown, this light source Assembly 100 includes: the adjustable graphene LED chip of emission wavelength 10, for launching LED primary colours of different wave length primary lights Light source 11 and the 2nd LED primary light source 12.
