碩士 === 國立中央大學 === 光機電工程研究所 === 98 === Application of field value programmable simulation techniques to establish programs and processes. 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.
