Design of both white LED and R-, G- and B-LED tow kind of backlight module. Focus on the LED package structure and the value of field technology and LED light box uniformity analysis and calculation. It can quickly design and analysis the backlight module. The purpose of achieving high uniformity. General optical simulation software for the optical light path tracing is very complex and difficult. Simulate a light box with diffuser in which all of the optical path is very time-consuming. Simulation of a group of 32-inch backlight module require so many times. But the value of field with this method, only simplified simulation of single LED light type distribution. So that to complete the lightbox simulate only in half an hour. The simulated data and optical simulation software, the average error of only 5%. Application of this process design two backlight module. White LED backlight to achieve uniformity of 95.6% in brightness. Red, green and blue LED uniformity of can reach 92.84% in brightness. To achieve accurate and efficient design. en_US DC.subject 直下式背光模組 zh_TW DC.subject 光跡模擬 zh_TW DC.subject 液晶顯示器 zh_TW DC.subject 發光二極體 zh_TW DC.subject liquid crystal displays en_US DC.subject light emitting diodes en_US DC.subject light trace simulation en_US DC.subject backlight module en_US DC.title 運用光場程式化技巧快速設計LED直下式背光模組之研究 zh_TW dc.language.iso zh-TW zh-TW DC.title Application of field programmable techniques to design LED backlight module en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
