Title: Screen
Inventor: OGUSHI YOICHI
IPC: G03B21/60
Filed: 1991-11-25
Abstract: PURPOSE:To improve the visibility of an image projected on a screen. CONSTITUTION:Screen gains Gi (i=1, 2...n) of the screen 2 vary with the quantity of incident light and when the quantity of incident light increases to the center part of the screen 2 and the quantity of incident light decreases to the peripheral part, the screen gains Gi of the screen 2 are so distributed that G1<G2<...<Gn. Consequently, the brightness distribution of the screen can be made uniform irrelevantly to the quantity of incident light, so when the screen 2 is applied to a projection type projector, the brightness difference between the center part and peripheral part of the screen 2 becomes small, so the display image becomes bright and the image (character, etc.) at the peripheral part is clearly seen.
