The invention disclosure provides a display and relates to the augmented real-world technical field. The display comprises an objective unit which is used for receiving the real image of an external scene, a micro-display which is used for generating a virtual image, a beam splitter which is used for receiving the real image and the virtual image and combining two images to produce a combined image, a first polarizer which is arranged between the objective unit and the beam splitter to control the light of the real image to be in a first polarization state before entering the beam splitter, a second polarizer which is arranged between the micro-display and the beam splitter to control the light of the virtual image to be in a second polarization state before entering the beam splitter, and a third polarizer which is arranged on the outgoing light path of the beam splitter, and comprises a first polarizing region and a second polarizing region. The third polarizer is used for controlling the light which comes out from the beam splitter and has different polarization states come out by corresponding to the first polarizing region and the second polarizing region. According to the invention, the real image is masked by the virtual image, and the image fusion effect is enhanced.
Description
technical field [0001] The present disclosure relates to the technical field of augmented reality, and in particular, to a display. Background technique [0002] AR (Augmented Reality, Augmented Reality) technology can apply virtual information to the real world, so that virtual objects and real environments can be superimposed on the same screen or in the same space in real time and exist at the same time. Currently, AR technology has been applied to fields such as medical and military training, engineering design and prototyping, teleoperation and telepresence, and personal entertainment systems. [0003] Taking the see-through head-mounted display based on AR technology as an example, it can combine the virtual image generated by the display with the real image of the real scene, and the desired effect of the fusion image is as follows. figure 1 As shown, that is, the virtual car 101 can block the real physical platform 102 behind it, thereby providing a real and coordin...
