Manufacturing of lc - use light guide plates , lc - related products , surface light emitting products , plastic nameplates , precision processed products 液晶專用導(dǎo)光板,液晶相關(guān)產(chǎn)品,面發(fā)光產(chǎn)品,塑料標牌,精密加工產(chǎn)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 超薄導(dǎo)光板燈箱是采用導(dǎo)光板所形成的背光模組,組合多種多樣的外框材料而制成的一種多功能的新的打不破的廣告載體。
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,國內(nèi)外生產(chǎn)的導(dǎo)光板都是基于幾何光學(xué)原理進行設(shè)計的,本文提出一種新型導(dǎo)光板? ?光柵型導(dǎo)光板的設(shè)計和制作方法。
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 為追求尺寸精度和縮短打磨加工時間,我們盡可能降低放電加工和nc直雕面的粗糙度,并應(yīng)用于要求具有鏡面光潔度的導(dǎo)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 通過對亞微米光柵衍射特性的分析,總結(jié)出只要控制光柵周期及入射光的角度,亞微米光柵就具有實現(xiàn)光波導(dǎo)的功能,為利用亞微米光柵制作導(dǎo)光板提供理論基礎(chǔ)。
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 電腦等液晶配件中使用的導(dǎo)光板,新店面的pop廣告牌,這些引人注目的各式超薄招牌等使用的都是面發(fā)光產(chǎn)品。我們利用好的創(chuàng)意,使光的用途在各個相應(yīng)領(lǐng)域擴大開來。
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 本文設(shè)計的亞微米光柵型導(dǎo)光板為矩形狀的,導(dǎo)光板上表面的導(dǎo)光單元是由三套出射光主波長分別是紅光632 . 8nm ,綠光521nm ,藍光441 . 6nm的亞微米光柵組成,光源采用的是紅、綠、藍三色發(fā)光二級管或者半導(dǎo)體激光器陣列,為了提高光能利用率,除入光面和出光面外,導(dǎo)光板其余面都鍍上金屬膜。
