Description

一种广视角的PDLC组合物 A widely viewing angle PDLC compositions

技术领域 FIELD

[0001]本发明涉及液晶材料技术领域,特别是一种广视角的roLC组合物,尤其涉及一种应用于调光膜、调光玻璃、智能背投等调光技术领域中的、具有较广视角的roix调光材料。 [0001] The present invention relates to the technical field of liquid crystal material, particularly to a wide viewing angle roLC composition, particularly to a technical field modulation dimming film, light control glass, and the like intelligent projection, having a wide Perspective roix dimming material.

背景技术 Background technique

[0002] 聚合物分散液晶(Polymer Dispersed Liquid Crystal,简称]^LC)是通过聚合物形成网络,将液晶以微米量级的小微滴分散在其聚合物网络内,一般将其制成光学薄膜。 [0002] PDLC (Polymer Dispersed Liquid Crystal, referred] ^ LC) is formed by a polymer network, the liquid crystal on the order of micrometers small droplets dispersed within its polymer network, which is typically made of optical film .

[0003] 由于液晶微滴的光轴散乱,其非寻常光折射率与聚合物网络的折射率不匹配,且不同取向的光轴的液晶微滴之间折射率也不匹配,当光通过基体时在微滴/网络、微滴/微滴界面处发生强烈散射从而呈不透明的乳白状态或半透明状态。 [0003] Since the liquid crystal droplets scattered optical axis, refractive index of extraordinary light refractive index of the polymer network does not match the optical axis and different orientations of liquid crystal droplets is not a match between the refractive index, when the light passes through the base when the droplet / network droplet / droplet at the interface so that the strongly scattering state was milky white opaque or translucent state.

[0004] 施加电场可使液晶微滴的光轴转向,当液晶的非寻常光折射率与聚合物网络折射率相匹配时,呈现透明态,因此光垂直于膜面时,透过率最高。 Is applied [0004] The electric field can shift the optical axis of liquid crystal droplets, when the liquid crystal extraordinary refractive index and the refractive index of the polymer network matches, showing a transparent state, so that the light perpendicular to the film plane, the maximum transmittance. 当光与膜面呈一定夹角时,在这个角度上折射率匹配程度不如垂直方向,因此造成一定程度上的光散射,在这个角度观察膜面,膜的透过率降低,膜面散射光造成视角问题。 When light with the membrane-section a certain angle, this angle index matching in the vertical direction than the degree, thus causing a certain degree of light scattering, the film surface was observed at this angle, the transmittance of the film decreases, the film surface scattered light Perspective cause problems. 除去电场,液晶微滴又恢复最初的散光状态,从而实现两种状态的转换,因为关态散射率很高,关态散射率上的差异不显著。 Electric field is removed, the liquid crystal droplets astigmatism and restore the original state, thereby achieving the conversion of two states, off-state scattering because of the high rate, the difference in the off rate is not significantly scattered.

[0005] PDLC材料可以用于制备调光膜、智能调光玻璃、电子价签、显示器等产品,目前在商业空间装饰、酒店装潢、办公室隔断、投影展示、光学调制器、热敏及压敏器件、电控玻璃、 光阀、电子书领域现阶段已经有较广泛的应用。 [0005] PDLC materials can be used to prepare the light control film, smart glass, electronic price tags, displays, and other products currently in commercial space decoration, decoration hotel, office partitions, projection display, optical modulators, and a thermal-sensitive means, electrically controlled glass, light valve, an electronic book art stage has broader applications.

[0006] PDLC有很多重要参数,包括光电响应曲线、透过率、驱动电压、粘接力、寿命粘接力、视角等。 [0006] PDLC has many important parameters, including photoresponse curve, the transmittance, the driving voltage, adhesive strength, adhesion life, viewing angle. 其中对客户体验影响最大的是透过率与视角。 The most influential is the transmittance and perspective on the customer experience. 因此良好的视角对H)LC的市场有很大的影响。 Therefore, a good viewing angle has a great influence on H) LC market.
