Description

具窄粒径分布有机颗粒的光学薄膜技术领域本发明涉及光学薄膜领域,特别涉及一种具窄粒径分布有机颗粒的光学薄膜,尤其涉及一种用作液晶显示器背光模块中的扩散膜的光学薄膜。 BACKGROUND optical film with narrow particle size distribution of the organic particles of the present invention relates to optical films, and more particularly relates to an optical film comprising organic particles having a narrow particle size distribution, and particularly to an optical diffusion film used as a liquid crystal display backlight unit of the film. 背景技术液晶显示器因其具有高画质、低辐射、低消耗功率、较佳空间利用性等优越性,已取代阴极射线管而成为市场主流。 BACKGROUND Liquid crystal displays because of its high quality, low radiation, low power consumption, better utilization of space and other advantages, have replaced cathode ray tube become mainstream. 由于液晶显示器中的液晶面板本身并不会发光,故须借助背光模块提供液晶面板所需的面光源,使液晶面板达到显示的效果,同时获得足够的亮度与对比度。 Since the liquid crystal display, the liquid crystal panel itself does not emit light, and thus should be provided by the surface light source for a backlight module of the liquid crystal panel, the liquid crystal display panel to achieve the effect, while obtaining a sufficient brightness and contrast. 构成背光模块的主要组件包括入射光源、反射膜、导光板、扩散板、扩散膜、聚光膜、 以及棱镜保护片等。 The main components constituting the backlight module includes an incident light source, a reflection film, a light guide plate, a diffusion plate, a diffusion film, a light-condensing film, the protective sheet and a prism and the like. 扩散板和扩散膜的主要功能为提供液晶显示器均匀的面光源, 一般分为内部扩散型与表面扩散型。 The main function of the diffusion plate and the diffusion film is uniform surface light source to provide a liquid crystal display, it is generally divided into surface and internal diffusion type diffusion type. 内部扩散型由含有机或无机扩散颗粒的聚碳酸酯(Polycarbonate, PC)树脂、聚苯乙烯(polystyene)或聚甲基丙烯酸甲酉旨(Polymethyl methacrylate, PMMA)树脂所组成,利用扩散颗粒,使光线在两个折射率相异的介质中穿过,产生折射和散射现象,从而将光源射出的线光源扩散成均匀的面光源,即让下方光源的光线透过扩散板产生漫射,向上均匀分散后于正面射出。 By the internal diffusion type polycarbonate (Polycarbonate, PC) resin, polystyrene (polystyene) contains organic or inorganic particles or the diffusion of polymethyl methacrylate unitary purpose (Polymethyl methacrylate, PMMA) resin composition, the use of diffusing particles, so light in a medium the refractive index difference of two through, refraction and scattering phenomena, so that the light emitted from the line light diffusing into a uniform surface light source, i.e., so that the light diffusion is generated through Fangguang Yuan diffusion plate, a uniform upward positive dispersion after injection. 表面扩散型则使透明树脂板的表面粗糙化,从而反射及折射光线, 但此做法的制作过程较费时且复杂,所需成本也相对较高。 The surface of the diffusion surface of the transparent resin plate is roughened, so that reflection and refraction of light, but this approach is time-consuming and the production process is relatively complicated, the cost is relatively high. 现有技术中使用粒径大小不同的颗粒作为扩散颗粒,以增强扩散膜的光扩散效果。 The prior art use of different particle size particles as diffusing particles, to enhance light diffusion effect of the diffusing film. 公知的扩散膜在基材上形成包含多个粒径大小不同的扩散颗粒的树脂涂层,扩散颗粒的粒径一般在1至50微米范围之间。 Particle diffusion known film-forming resin coating layer comprises a plurality of diffusing particles of different particle sizes on the substrate, diffusing particles is generally between 1 and 50 microns. 现有技术所采用的扩散颗粒具有宽粒径分布,即当以数量为纵轴、 粒径大小为横轴作图时,树脂涂层中的扩散颗粒粒径分布呈宽单峰状分布。 Diffusing particles employed prior art has a wide particle size distribution, i.e. when the number of the vertical axis to, the axis of abscissa as particle size, diffusion particle size distribution of the resin coating was br-like distribution. 例如,当现有技术所采用的颗粒的平均粒径为15微米时,扩散颗粒的粒径分布常为1至30微米。 For example, when the average particle diameter of the particles used in the prior art is 15 microns, a particle size distribution of the diffusing particles is usually 1 to 30 microns. 另外,可采用两组以上具有不同平均粒径的扩散颗粒的混合物,即扩散颗粒粒径分布(以数量为纵轴, 粒径大小为横轴)呈双(多)峰状分布。 Further, a mixture of two or more may be employed diffusion particles different average particle sizes, i.e., diffusing particles size distribution (in volume as the vertical axis, the horizontal axis particle size) as a bis (poly) peak-like distribution. 然而,虽然使用宽单峰状分布或双(多)峰状分布的扩散颗粒可使光扩散效果充分发挥,但同时由于扩散颗粒的粒径不一,会使光的散射十分散乱, 而造成光源无法有效利用。 However, although the use of br-like distribution or bis (poly) peak-like distribution of the diffusing particles allow full light diffusion effect, but since the particle size of particles of varying diffusion, scattering of light will very scattered, causing the light source can not effectively use.

当涂层中的扩散颗粒彼此聚集或黏附时,不但会影响扩散光线的均匀度且容易使显示器表面上产生暗点。 When the aggregated particles diffusion coating or adhesion to one another, not only affect the uniformity of the diffused light and easy to make a dark spot on the display surface. 为解决上述问题,US7,218,450B2使用一种或多种单分布的有机或无机颗粒作为扩散颗粒,并以特定式要求黏附比率、已聚集颗粒的粒径及使用两种单分布颗粒时, 此两种单分布颗粒的平均粒径值。 To solve the above problems, US7,218,450B2 distributed using one or more single organic or inorganic particles as the diffusing particles, and a ratio of a specific formula in claim adhesion, and has an aggregate size of single particles of two particle distribution, this value of the average particle size distribution of two single particles. US 7,218,450 B2所使用的单分布颗粒中,95%颗粒的粒径落于其平均粒径的±15%的范围内。 US 7,218,450 B2 single distribution of the particles used, the particle size of 95% of the particles fall within the range of the average particle diameter thereof of ± 15%. US 7,218,450 B2已公开了使用粒径分布范围较窄的扩散颗粒,但未针对扩散颗粒的交联度进行讨论。 US 7,218,450 B2 discloses the use of particle size distribution is narrower diffusing particles, but not discussed for the diffusion degree of crosslinking of the particles. 事实上,扩散颗粒的交联度不足将导致一些无法避免的问题。 In fact, the diffusion of particles less than the degree of crosslinking will lead to some unavoidable problems. 例如,交联度低的颗粒易与接合剂中的溶剂作用产生膨润(swelling)现象,因此,相比于交联度高的颗粒,交联度低的颗粒的耐溶剂性较低;另外,交联度低的颗粒因吸收溶剂造成体积变化,将导致颗粒的光学性质不稳定,且颗粒的表面会产生增黏现象,易使颗粒与颗粒之间产生凝聚现象,进而影响扩散膜的涂布加工性以及其光扩散效果。 For example, particles of low degree of crosslinking is easy to produce and as a solvent bonding agent swelling (swelling) and, therefore, compared to the high cross-linked particles, the solvent resistance of the particles of low degree of crosslinking is low; Further , low degree of crosslinking of the particles due to volume changes caused by absorption of the solvent, the optical properties of the particles will lead to instability of the surface of the particles and tackifying phenomenon will produce, easy to produce agglomeration between the particles and the particles, thereby affecting the diffusion coating film cloth workability and light diffusion effect thereof. 此外,在各种光学膜片中,聚光膜价格相对较高,因此在新发展的背光模块结构中,为了降低成本,倾向其它光学膜片及其组合上作变化以取代聚光膜。 Further, in various optical films, a condensing film price is relatively high, so the structure of the backlight module in the new development in order to reduce costs, the other tends to be varied in the optical film, and combinations thereof instead of condensing film. 如对于液晶监视器,以二片或三片扩散膜的设计来取代先前聚光膜与其上下各一片扩散膜的设计,但此做法的辉度及其它产品效能却不能与原有设计相比,因此对于目前的现有技术,扩散膜的设计重点不仅在于如何达到符合光扩散效率的要求,更需进一步考虑如何提高扩散膜的辉度。 The liquid crystal monitor, to two or three diffusion films designed to replace the previous design a condensing film with its respective vertical diffusion membrane, but this approach of the luminance and other product performance as compared with the original design can not, So for the current prior art, the proliferation of film design focus not only on how to achieve compliance with the requirements of light diffusion efficiency, but also need to consider further how to improve the brightness diffusion membrane. 发明内容为了提高光学薄膜的光扩散效率及辉度,本发明提供了一种光学薄膜。 SUMMARY To improve the efficiency of light diffusion and luminance of the optical film, the present invention provides an optical film. 所述技术方案如下:一方面,提供了一种光学薄膜,包含一透明基材、位于该透明基材的一表面上具有凹凸结构的树脂涂层,所述树脂涂层包含多个有机颗粒和接合剂;所述多个有机颗粒为聚丙烯酸酯树脂,其包含至少一种单官能基的丙烯酸酯类单体及至少一种多官能基的丙烯酸酯类单体作为聚合单元,所有多官能基的丙烯酸酯类单体占总单体重量份的30%至70%;所述多个有机颗粒具有单一平均粒径且所述多个有机颗粒的粒径分布落于该平均粒径的±5%范围内;所述多个有机颗粒相对于接合剂固形份的量为每100重量份接合剂固形份为180重量份至320 重量份的有机颗粒。 The technical solutions are as follows: In one aspect, there is provided an optical film comprising a transparent substrate, a resin coating layer having a concavo-convex structures on the surface of the transparent substrate, the resin coating layer comprises a plurality of organic particles and cement;
