Abstract
The present application provides a display device and glasses. The display device includes an optical waveguide, a first and second projectors, at least one optical sensing assembly, and a feedback tracking device. The first and second projectors respectively project a first light with a wavelength of visible light wavelength and a second light with a wavelength of second wavelength to a coupling-in device. The optical sensing assembly is arranged corresponding to a coupling-out device, and includes at least one imaging device. The feedback tracking device is electrically connected to the first projector and the light sensing assembly. The optical sensing assembly is used for receiving the second light reflected by human eye. The feedback tracking device adjusts the first projector according to the second light received by the optical sensing assembly such that the first light coupled out of the coupling-out device follows a line of sight of human eye.
