发明名称 REAR PROJECTION FABRIC, REAR PROJECTION SCREEN, AND REAR PROJECTION SYSTEM
摘要 <p>Thin high-density fabrics are particularly suitable for super wide-angle rear projections that are accurate in every detail. Based on said recognition, the invention relates to a rear projection fabric (20, 30) that comprises a number of threads (21, 23, 31, 33) and has a density of more than seven threads per millimeter, the maximum diameter of a thread being less than 0.06 mm. The invention further relates to a rear projection screen (10) which comprises such a rear projection fabric (20, 30) and can create a wide-angle rear projection image (41) that is particularly accurate in every detail. More particularly, such a rear projection screen (10) makes it possible to create a relatively inexpensive rear projection system (40) which can be designed by means of the standard power of a projector (43), e.g. in the form of a beamer or laser.</p>
