碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 93 === The liquid crystal displays itself has a lot of advantages, such as thin thickness, slight weight and high brightness, etc. It is an important target for many engineers to develop the high brightness, uniformity, low power consumption and thin backlight module. Due to the temperature raising of the cold cathode fluorescence lamp (CCFL) in a backlight module of a LCD under long-term lighting state, the micro-optic-structure will deform and cause an uneven luminance phenomenon. In this research, was provided a method of creating a model with thermal deformation and how to draw this model by using PRO/EINGINEER. Then, one can transform the model into the optical software, ASAP, to make optical analysis. Finally, the thermal module can be studied.
