Patent number: 9939715Abstract: A projection device is disposable into a display platform of a display rack having a plurality of display platforms, for directly projecting an image frame onto a projection screen of the display platform. The image frame projected to the projection screen is not reflected by any reflective mirror arranged between the projection device and the projection screen. A length of the image frame in a first direction is equal to at least ten times a length of the image frame in a second direction. Since no reflective mirror is arranged between the projection device and the projection screen, the projection device is more easily applicable to display racks.Type: GrantFiled: December 28, 2015Date of Patent: April 10, 2018Assignee: YOUNG OPTICS INC.Inventors: Ching-Lun Lin, Ming-Chi Chen, Ya-Ling Hsu, Wen-Hao Hsu, Chao-Shun Chen, Wei-Hung Tsai
