OPTICAL TRANSMISSION DISPLAY SYSTEM USING INTEGRATED LIGHT SOURCE

摘要

PURPOSE: An optical transmission display system using an integrated light source is provided to irradiate uniformly the light on a display side by installing a light diffusion body, a refraction plate, and a reflective plate in a light guide. CONSTITUTION: A light guide(10) includes a reflective plate, a triangular refraction plate, and a triangular space part. The reflective plate(12) is adhered on the remaining sides except for a display side(13) of a protection cap(11). The triangular refraction plate(14) is formed on all inner sides except for the reflective plate of an opposite side. The triangular space part(15) is formed between the reflective plate and the triangular refraction plate. A light diffusion body is formed in the inside of the light guide in order to irradiate uniformly the light on the display side.
