Recent advances in microlens-based projection display screens

摘要

In the past few years the microdisplay-based projection television market has been quickly spreading over what used to be the domain of CRT technology. The demand for larger display sizes and improved image quality, together with more accessible pricing is aggressively driving the transition to microdisplays. The screen is the component of the projection system that directly conveys the visual information to the user, responsible for distributing the luminous energy from the light engine. However, the projection screen is far from a simple diffuser and today's performance requirements for display systems require sophisticated screens to meet the resolution, transmission efficiency, and contrast required by visual displays.
