Description
Technical field
The present invention system refers to a kind of reflectance coating that is used for liquid crystal display backlight module especially about a kind of reflectance coating.
Background technology
LCD (Liquid Crystal Display, LCD) have superiority such as high image quality, low radiation, low consumpting power, preferable space utilization because of it, replace original cathode-ray tube (CRT) (Cathode-Ray Tube, CRT) display and become the market mainstream gradually.LCD this as non-self light-emitting display device, therefore need backlight module (Back light module) to provide the liquid crystal display displays image required light source, so that its normal show image.
The main composition assembly of backlight module comprises: incident light source, reflectance coating, light guide plate, diffuser plate, diffusion barrier, condensing film and prism screening glass etc. are broadly divided into two kinds of straight-down negative and side-light types according to its structure.Direct type backlight module is that light source is configured under the diffuser plate, is applied to larger-size display equipment usually, for example TV; Side light type back light module then is configured in light source the side of light guide plate, penetrates after making light source via light guide plate correcting direction, is applied to the small-size display device usually, for example mobile computer and monitor etc.
The major function of reflectance coating is that light with scattering reflexes to light guide plate or diffuser plate in the middle of the backlight module component, to improve the utilization ratio of light.Generally speaking, the reflectance coating of direct type backlight module is arranged on the lamp box lower surface or pastes thereon, will be through diffuser plate beam reflected reflected back diffuser plate and utilizing again once more; The reflectance coating of side light type back light module then is arranged on below the light guide plate, to light guide plate, to reduce light losing, increases the utilization ratio of light in order to the beam reflection of the transmission that will not have through light guide plate directly to make progress.
The common used material of reflectance coating is generally white plastic, as polycarbonate (polycarbonate, PC) or polyethylene terephthalate (polyethylene terephthalate, PET), by adding inorganic filler, as titania (TiO
2) or barium sulphate (BaSO
4) etc., to promote the reflection coefficient of reflectance coating.But, inorganic fillers such as titania can absorb the light of specific wavelength, cause the reflection coefficient of certain particular range of wavelengths to reduce, to this, US 5,672, and 409 disclose to use and a kind ofly to have the white polyester film of slight void as reflectance coating, to reduce above-mentioned light absorption, increase the reflection coefficient of reflectance coating.
For improving optical efficiency and take into account brightness of backlight module and homogeneity, the existing multinomial design that improves at the reflectance coating structure in this area, for example No. the 593926th, Taiwan patent announcement, I232335 number.In addition, US 6,906,761 B2 disclose a kind of reflectance coating, form the anti-scratch layer with certain surface roughness on white synthetic resin base material, and this anti-scratch layer comprises cement, be dispersed with the particle that constitutes with resilient material in the cement, utilize white synthetic resin base material to reach the purpose of reflection, and, further improve the brightness and the homogeneity of reflectance coating by the scratch between above-mentioned anti-scratch layer minimizing reflectance coating and other diaphragm (as light guide plate).
For promoting the service efficiency of light, US 6,943,855 B2 utilize coating one deck to contain the coating of Chinese white (comprising titania basically) in the back side of synthetic resin base material, form luminosity (luminosity) greater than 95 high shielding layer (highly concealing layer), improve the reflectivity properties of reflectance coating whereby and cover character, and reduce the light leak at the reflectance coating back side.US 6,943, the further teaching of 855B2, can in the another side of base material form include cement and granule proliferation diffusion layer with diffusion light, thereby the enhancing reflectance coating cover character.Yet US 6,943, and how 855 B2 do not announce the method with the effective homogenising of ejaculation light of reflectance coating.As US 6,943,855 B2's is shown in Figure 2, and the granule proliferation that it adopted is to be distributed in arbitrarily in the middle of the diffusion layer, overlapping situation may occur between the granule proliferation.Yet the overlapping phenomenon of granule proliferation may influence the irradiant uniformity coefficient of reflectance coating, and because opticpath increases, the energy loss in the light traveling process is inevitable also can be increased.In addition, US 6,943, and the particle size distribution range of the granule proliferation of 855 B2 is wider, easily make the scattering of light very at random, light effectively can't be utilized.
Therefore, how to improve the optical property of reflectance coating, reduce the light source waste, available light at utmost is utilized, become the problem that Related Research Domain is desired most ardently solution.Yet, when utilizing reflectance coating to reduce the light source waste and strengthening the brightness of backlight film group, effectively the optical field distribution of control light reflection to be taking into account the uniformity of light from reflectance coating to other diaphragm, and its front face brightness or briliancy are significantly gained, also the problem that should manage to overcome for Related Research Domain.
