Detailed description of the invention
Fig. 1 is the axonometric chart of the display device 100 according to one embodiment of the present invention. Fig. 2 is the display device 100 profile along line segment 2-2 of Fig. 1. Consulting Fig. 1 and Fig. 2, display device 100 comprises luminous body 110 and brightness enhancement film 120 simultaneously. Luminous body 110 has exiting surface 112, and brightness enhancement film 120 is positioned on the exiting surface 112 of luminous body 110. Brightness enhancement film 120 comprises multiple optics microparticle 124a, 124b, 124c that base material 122 and size are between 2 ��m to 4 ��m. Brightness enhancement film 120 can have the optics microparticle of one or more sizes. In the present embodiment, brightness enhancement film 120 has three kinds of various sizes of optics microparticle 124a, 124b, 124c, but is not intended to limit the present invention. Optics microparticle 124a, 124b, 124c are dispersed evenly in base material 122. Wherein, the size being sized larger than optics microparticle 124b of optics microparticle 124a, and the size being sized larger than optics microparticle 124c of optics microparticle 124b, as shown in Figure 2.
Optics microparticle 124a, 124b, 124c of brightness enhancement film 120 have the characteristic of total reflection. The material of optics microparticle 124a, 124b, 124c can be selected from the group that the oxide of periodic table of elements 4B race and 3A race forms. Wherein, periodic table of elements 4B race comprises titanium (Ti), zirconium (Zr), hafnium (Hf) and stove (Rf), and 3A race comprises aluminum (Al), gallium (Ga), indium (In) and thallium (Tl). For example, optics microparticle 124a can be aluminium oxide, and optics microparticle 124b can be zirconium oxide, and optics microparticle 124c can be titanium oxide. In other embodiments, iron sesquioxide and silicon dioxide also can as the materials of optics microparticle.
Intersperse among optics microparticle 124a, 124b, 124c in base material 122 can reflect and the light in refraction brightness enhancement film 120. For example, when the surface 126 of light L1 transmission to brightness enhancement film 120, due to base material 122 different from the refractive index of air (refractive index of air is about 1), refraction light L2 and reflection light L3 can therefore be produced. The light L3 of reflection can be formed light L4 by optics microparticle 124b reflection, and then light L4 may pass through the surface 126 of brightness enhancement film 120, forms refraction light L5 and goes out light. In the present embodiment, light in brightness enhancement film 120 is except being reflected and except refraction by optics microparticle 124b, also can by optics microparticle 124a, 124c reflection and refraction, optics microparticle 124a, 124b, 124c all can promote light extraction efficiency and the forward amount of light of luminous body 110. In this article, " forward " refers to that the light that luminous body 110 produces can be directed at that display device 100 is outer and direction in order to show image, for instance pass the direction on brightness enhancement film 120 surface 126.
Additionally, in the present embodiment, luminous body 110 can be Organic Light Emitting Diode (OrganicLightEmittingDiode; OLED) display floater, its refractive index substantially 1.5. In this article, the error manufactured can " substantially " be referred to, for instance the range of error of 10%. In the present embodiment, the material of base material 122 can comprise polydimethylsiloxane (Polydimethylsiloxane; PDMS) so that the refractive index of base material 122 also substantially 1.5. Consequently, it is possible to the refractive index of base material 122 just can be similar to the refractive index of luminous body 110. In other embodiments, the material of base material 122 also can be selected for polymethyl methacrylate (Polymethylmethacrylate; PMMA) make.
Owing to the refractive index of the base material 122 of brightness enhancement film 120 is roughly the same with the refractive index of luminous body 110, when luminous body 110 is lighted, light not easily produces total reflection in luminous body 110. For example, when light L1 goes out light from the exiting surface 112 of luminous body 110, completely into, in brightness enhancement film 120, being not likely to produce reflection light L6, light extraction efficiency and the forward amount of light of luminous body 110 can therefore can be promoted. In the present embodiment, the material of brightness enhancement film 120 itself has viscosity, can directly be superimposed on luminous body 110, but in other embodiments, brightness enhancement film 120 is attached on luminous body 110 also by optical cement, as shown in Figure 4.
Intersperse among the design in base material 122 by optics microparticle 124a, 124b, 124c, make the brightness enhancement film 120 of the present invention have the effect promoting luminous body 110 light extraction efficiency and forward amount of light. Consequently, it is possible to the brightness enhancement film 120 with base material 122 and optics microparticle 124a, 124b, 124c just can promote light briliancy and the brightness of display device 100, and then promote the product competitiveness of display device 100. The display device 100 of the present invention, compared with the luminous body 110 not attaching brightness enhancement film 120, can promote the brightness of about 62%. Additionally, in other embodiments, designer is also with the brightness enhancement film 120 of optics microparticle 124a, 124b, 124c of tool heterogeneity (such as size and material), changes the light emission color temperature of luminous body 110.
Additionally, brightness enhancement film 120 also relatively has elasticity for the design aspect of display device 100, for instance designer can be selected for the luminous body 110 that light briliancy and brightness are relatively low, and promote light briliancy and the brightness of luminous body 110 by brightness enhancement film 120, to save cost. Or, display device 100 is because having brightness enhancement film 120, and designer can reduce the output of luminous body 110, extends the service life of luminous body 110.
In the present embodiment, optics microparticle 124a, 124b, 124c account for the percentage by weight 1% to 5% of overall brightness enhancement film 120. Additionally, the transmittance of base material 122 can between 90% to 100%, and the thickness D of base material 122 can between 200 ��m to 450 ��m. Owing to the transmittance of base material 122 high and thick degree D is thin, therefore the microminiaturization design for the transmission of light with display device is all benefited to some extent.
In the following description, as luminous body and will test using Organic Light Emitting Diode, compare the light briliancy of the luminous body attaching brightness enhancement film and do not attach brightness enhancement film.

As it can be seen, lower section broken line represents the luminous body light briliancy 210 not attaching brightness enhancement film, and top broken line represents the luminous body light briliancy 220 attaching brightness enhancement film. Wherein, light briliancy is the light intensity density of the per surface of shiner, refers to the luminous intensity of shiner. The luminous body light briliancy 210 not attaching brightness enhancement film is known with the result of the luminous body light briliancy 220 attaching brightness enhancement film, attach the luminous body of brightness enhancement film, the light briliancy of its all measuring points is all higher than the luminous body not attaching brightness enhancement film, representing that the luminous intensity of the luminous body attaching brightness enhancement film is higher, amount of light is more. Therefore, the brightness enhancement film of the present invention can promote the light briliancy of display device really effectively.
