摘要 目前，液晶顯示器因成為平板顯示的新寵兒，并且在未來的日子里必定會(huì)代替CRT顯示器的存在，成為主流的顯示器，但是LCD本身并不會(huì)發(fā)光，需要背光模組來實(shí)現(xiàn)發(fā)光顯示的功能，所以背光模組漸漸成為了液晶顯示的主流裝配。隨著背光模組向著輕薄化的發(fā)展，對(duì)于背光模組中的重要組件導(dǎo)光板的設(shè)計(jì)也成了當(dāng)前的熱門課題，背光模組的發(fā)展也就和導(dǎo)光板的高效設(shè)計(jì)和制造息息相關(guān)了。本文所研究的重點(diǎn)在于導(dǎo)光板在小尺寸的側(cè)光式背光模組中的設(shè)計(jì)方法。
本文第一部分首先介紹的是顯示技術(shù)的基礎(chǔ)，并且介紹了多種的顯示技術(shù)。然后介紹了液晶顯示和導(dǎo)光板的發(fā)展現(xiàn)狀以及將來的發(fā)展趨勢(shì)。最后介紹了本文主要研究的內(nèi)容。
第二部分介紹了非成像光學(xué)的發(fā)展情況，闡述了成像光學(xué)與非成像光學(xué)的不同，之后介紹了非成像光學(xué)基本概念，并對(duì)一些基本參數(shù)進(jìn)行介紹，詳細(xì)介紹了兩個(gè)重要的參量：能量收集率、光學(xué)擴(kuò)展量。
第三部分首先介紹了液晶顯示技術(shù)的基本原理和組成，并且對(duì)背光模組各組件進(jìn)行說明和分析，之后詳細(xì)介紹了側(cè)光式背光模組中重要部件導(dǎo)光板的工作原理和光學(xué)制作方法，闡明一些設(shè)計(jì)過程中需要的理論基礎(chǔ)。
第四部分先闡述了幾何光學(xué)中一些基本原理在導(dǎo)光板中的運(yùn)用，然后介紹了比較成熟的網(wǎng)點(diǎn)設(shè)計(jì)理論，介紹模擬使用的設(shè)計(jì)軟件LIGHTTOOLS所具備的功能，詳細(xì)說明了其中的優(yōu)化模塊。然后使用LIGHTTOOLS對(duì)不同網(wǎng)點(diǎn)結(jié)構(gòu)設(shè)計(jì)的導(dǎo)光板進(jìn)行光線追跡，之后再進(jìn)行分析它們對(duì)光線的引導(dǎo)效果，并在此基礎(chǔ)上，進(jìn)行優(yōu)化，設(shè)計(jì)出一款均勻度達(dá)到85%的背光模組結(jié)構(gòu)模型。
最后就是對(duì)所研究的內(nèi)容歸納分析，并給出以后所要研究的方向道路。

LIGHTTOOLS used in the light guide plate design


Abstract Currently, due to liquid crystal display becomes the new darling of the flat panel display, and in the coming days will certainly replace the presence of CRT monitors, but the LCD itself does not glow, is the need for light-emitting display backlight, LED backlight gradually become the mainstream of the liquid crystal display configuration, however, since the light guide plate having a light guide functions and becomes the most important components of the backlight modules. With the backlight modules toward the light of the development, the design of the light guide plate has become the current hot topic, how to use the light guide plate to transform point or line source into surface source with uniform light, and efficient conduct design and production are closely related to backlight modules’ development. In this paper, the study is the small size guide plate of the edge-type backlight modules’ design.
The first part introduces the basic display technology, and introduces a variety of display technologies. Then that introduces the development status and the future trend of development of LCD and the light guide plate. Finally, this paper describes the contents of the study.
The second part describes the development of non-imaging optics, describes various imaging optics and non-imaging optics, and then introduces the basic concepts of non-imaging optics, and some basic parameters are introduced, detailing two important parameters: Concentration Ratio and .
The third part introduces the basic principles of LCD technology and composition, and the various components of the backlight modules description and analysis, followed by a detailed description of works of the light guide plate which is important parts of the edge-type backlight modules, clarify some design process requires theoretical basis.
Fourth section describes some of the basic principles of geometric optics in the use of the light guide plate, then introduces several network design theory, the light guide plate analog design software LIGHTTOOLS software features, and then using this software to perform several different light guide structure ray tracing analyzed the effect of different light guide structure of the light guide plate, and the uniformity of the design optimization of the ideal structure of the light guide plate model.
Finally, the subject of this study are summarized, and pointed out what can be done in the future work.
The final step is to analyze the contents and gives the future direction of the road of studied.
