Abstract:
1. An image-partitioned display device for virtual image comprising: an image display unit generating at least one image; a refractive element refracting and partitioning said image into a plurality of sub-images; and a virtual image generation module receiving lights of said sub-images to generate a large area image or a plurality of enlarged images, and said virtual image generation module further comprises: a relay lens receiving and relaying said lights of said sub-images, and then focusing said lights on within a focus point of a concave mirror, and said concave mirror reflects said lights of said sub-images relayed from said relay lens to enlarge said sub-images; and a plurality of combiners respectively receiving enlarged said sub-images from said concave mirror, and then reflecting and combining them into said large area image or said enlarged images, and each said combiner is a semi-transmitted mirror with a high reflectivity optical thin film, and said thin film has a transmission rate of between 70% and 75% and a reflection rate of between 25% and 30%, and a number of said combiners is equal to that of said sub-images.
