发明名称 OPTICAL TRANSMISSION PLATE
摘要 PURPOSE:To improve the quality of a transmitting picture and shorten a transmission time, and to reduce the size, weight, and cost of an applied equipment by irradiating a planar picture almost uniformly by a light emitting body layer. CONSTITUTION:The filmy light emitting body layer 22 is adhered to an optical transmission plate 21 while covered with an adhesive 7 except at lenses 2a on a plate surface facing to screen 17 of lenses 3a. Further, a light shielding layer 22a of carbon black is vapor-deposited at the part of the lens 3a where the light emitting body layer 22 is adhered so that no light is projected from the light emitting body layer 22 to the side of a picture plane 18. This constitution irradiates the screen 17 almost uniformly by the light emitting body layer 22, so an image on the screen 17 is transmitted onto an image plane 18 at a time by the optical transmission plate 21 which has a two-dimensional spread as a light image 15, which is formed. Thus, the quality of the transmit picture is improved and the transmission time is shortened; and the size, weight, and cost of the applied equipment are reduced.
