Method for Improving the Performance of Wide Screen Projection Display Illumination System
Illumination system is an important component of projection display system, and decides the whole brightness and uniformity of the whole system. Fly-eye system is a commonly used illumination configuration in liquid crystal display (LCD) projectors. In traditional fly-eye illumination systems, the elemental lens of fly-eye always has the same aspect ratio as the LCD device. But when applied to wide screen projection systems, this will lead to a certain energy loss. This paper presents a new method for improving the performance of wide screen projection display illumination systems, which introduces cylinder lenses. Results of simulation show that a total increment of about 5% to 10% of the output lumens is available with this improved fly-eye system.
