LCD背光源设计 摘 要 LCD和我们的日常生活的联系越来越紧密。众所周知，液晶自身是不能发光的，它需要借助背光源才能达到显示的功能。高精细LCD，必须有高性能的背光技术与之配合。因此设计一个高亮度、大视角并且稳定、均匀出光的背光源非常重要。 在产品开发初期，用实物搭建会造成不必要的浪费。目前的工程设计大多先采用模拟设计的方式建立模型。TracePro是一套能进行常规光学分析、设计照明系统、分析辐射度和亮度的软件。它是一个结合真实固体模型、强大光学分析功能、信息转换能力强及易上手的使用界面的仿真软件，它可以将真实立体模型及光学分析紧紧结合起来。 本论文主要介绍背光源组成结构，并基于TracePro软件模拟设计直下式背光源，并分析该设计的合理性。 关键词：LCD；背光源；CCFL；TracePro Design of LCD Backlighting Unit Abstract With LCD display and our daily life are more and more close. As is known to all, LCD itself is not shine, it needs some back light can achieve display function.High fine LCD, must have high technology and the coordination.Backlighting Therefore, a large design, high brightness, uniform and stable Angle from light back light is very important. Early in the product development, with real structures will cause unnecessary waste.At first the engineering design are designed by simulation model.TracePro is a set of conventional optical analysis, can design, lighting system and brightness of radiation.It is a combination of real solid model, strong optical analysis function, converting information ability and accessible using the simulation software interface, which can be real three-dimensional models and optical analysis combined tightly. This article mainly introduces structure, and the back light TracePro software simulation design based on straight down type illuminant, and analyzes the back the rationality of the design.
