Abstract
A multi-view display device is provided, and the multi-view display device at least comprises a projector, a first lens set, and a second lens set. The projector contains a scan-lamp image, and the projector slants an incident ray corresponding to the scan-lamp image with a first angle. The first lens set receives the slanted incident ray and refracts that. The second lens set is slanted with the first angle, and the second lens set receives the slanted incident ray which is refracted by the first lens set and refracts that again, so as to expand a view area of the multi-view display device.
Claims9
A multi-view display device providing a spatial-multiplex number of M×N required to be added by a user, wherein M is a number of horizontal pixels, N is a number of vertical pixels, M and N are positive integers, the multi-view display device comprises:
- a projector containing a scan-lamp image, the projector slanting an incident ray corresponding to the scan-lamp image with a first angle;
- and
- a first lens set constituted by a lens array receiving the slanted incident ray and refracting the slanted incident ray;
- and
- a second lens set constituted by a lenticular lens array, the second lens set being slanted with the first angle and receiving the slanted incident ray refracted by the first lens set and refracting the slanted incident ray refracted by the first lens set to allow a view area of the multi-view display device to have the spatial-multiplex number of M×N, wherein the first angle is defined as tan−1 (1/N)°.
