At last , the feasibility of fabricating light guide plate by double beam laser direct writing system is confirmed 最后论证用双光束激光直写系统制作亚微米光栅型导光板的可行性。
Manufacturing of lc - use light guide plates , lc - related products , surface light emitting products , plastic nameplates , precision processed products 液晶专用导光板,液晶相关产品,面发光产品,塑料标牌,精密加工产品
It is a new multi - functional advertising medium , which cannot be broken , and it applies the backlight model setting that is formed by light guide plate and integrates various material of frame 超薄导光板灯箱是采用导光板所形成的背光模组,组合多种多样的外框材料而制成的一种多功能的新的打不破的广告载体。
At present , the design of light guide plate in and abroad is based on geometrical optics principle . in this dissertation , a novel light guide plate fabricated by gratings is proposed , including its designing and fabricating method 目前,国内外生产的导光板都是基于几何光学原理进行设计的,本文提出一种新型导光板? ?光栅型导光板的设计和制作方法。
Moreover , in order to pursue dimensional precision and shorten the time required for grinding , we make the surface roughness of the electro - discharge and nc direct carving processes as small as possible , and apply this technique to the light guide plates , etc . , for which mirror polishing is required 为追求尺寸精度和缩短打磨加工时间,我们尽可能降低放电加工和nc直雕面的粗糙度,并应用于要求具有镜面光洁度的导光板等加工中。
By analyzing the diffraction properties of sub - micron gratings , it is summarized that sub - micron gratings can realize the function of light - guiding by controlling the period of gratings and the angle of incident light . the properties are the theory base of the designing light guide plate 通过对亚微米光栅衍射特性的分析,总结出只要控制光栅周期及入射光的角度,亚微米光栅就具有实现光波导的功能,为利用亚微米光栅制作导光板提供理论基础。
The plastic light guide plates used for lc parts in pcs , etc . , and the thin , energy - saving , multi - purpose panels that are gathering widespread attention as new type storefront pop point of purchase displays are just two examples of matsushita shokai s latest surface light source products 电脑等液晶配件中使用的导光板,新店面的pop广告牌,这些引人注目的各式超薄招牌等使用的都是面发光产品。我们利用好的创意,使光的用途在各个相应领域扩大开来。
The light guiding unit on the surface is composed of sub - micron gratings whose transmission wavelengths are red , green and blue in order . the light source are red 、 green 、 blue led or semiconductor laser array . to enhance the light utilization , the surfaces of light guide plate except the incident and transmitted surfaces are coated with metallic film 本文设计的亚微米光栅型导光板为矩形状的,导光板上表面的导光单元是由三套出射光主波长分别是红光632 . 8nm ,绿光521nm ,蓝光441 . 6nm的亚微米光栅组成,光源采用的是红、绿、蓝三色发光二级管或者半导体激光器阵列,为了提高光能利用率,除入光面和出光面外,导光板其余面都镀上金属膜。
