碩士 === 國立交通大學 === 顯示科技研究所 === 94 === On the basis of the application on the ultra-thin display of wedge-plate, color is one of the key factor, different from LCD、PDP or CRT shows and excites for the sub-pixel element position on the panel, wedge-plate utilizes the projector to be a light source, because the refraction index of the air and wedge-plate are different in each different wavelength, this will cause the chromatic dispersion phenomenon when the light leaving projector to wedge-plate. In this thesis, we use the ray tracing skill, the refraction index depend on the wavelength causing the angle relationship between wedge-plate and air, the relationships between incident angle and emitted position, we derive the formula mathematics model of the chromatic shift, and compare simulation with optics software, finally making one 14 inches of wedge-plate screen ,verify for the experiment. For the influence factor to forming an image, find out and deeply understanding, evaluate the error value between simulation and experiment, and research how to improve.
