LIGHT SOURCE UNIT AND IMAGE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18390954 titled 'LIGHT SOURCE UNIT AND IMAGE DISPLAY DEVICE
The abstract describes a light source unit that includes a display device and an imaging optical system. The display device has a pixel column with multiple pixels arranged along a first direction. The imaging optical system consists of a movable optical system and an output element. Light emitted from the display device is incident on the movable optical system, which is movable around an axis parallel to the first direction and emits light at an angle corresponding to its movement state. The light then passes through the output element, forming a first image. The imaging optical system is substantially telecentric at the first image side, and the light emitted from the display device has a Lambertian light distribution.
