Pancharatnam-Berry phase liquid crystal lens-based smart glasses

Abstract

The invention discloses a pair of Pancharatnam-Berry (PB) phase liquid crystal lens-based smart glasses, comprising a pair of glasses, PB phase liquid crystal lenses, a battery and a circuit driving device, wherein the PB phase liquid crystal lenses are embedded into lenses of the glasses or fit closely onto the lenses of the glasses; the circuit driving device and the battery are arranged in series on a handle of the glasses, and are connected in series with the PB phase liquid crystal lenses; and the display pixels of the smart glasses are formed by a single or more PB phase liquid crystal lenses, and an array of the pixels is driven directly by electricity or driven by a passive matrix or driven by an active matrix. According to the smart glasses disclosed by the invention, by virtue of manufacture and use of a liquid crystal PB phase lens array, on one hand, an artificial backlight source is not needed to realize a transparent display effect of switching between a blurred state and a clear state, the energy consumption is reduced, and a relatively strong endurance is achieved; and on the other hand, the operating voltage is relatively low, generally lower than 5V, so that the safety performance of head-mounted augmented reality is improved.

Description

technical field [0001] The invention relates to the field of augmented reality based on transparent display, in particular to smart glasses based on Pancharatnam-Berry phase liquid crystal lenses. Background technique [0002] Augmented reality technology is a new technology that "seamlessly" integrates real world information and virtual world information. After the simulation is superimposed, the virtual information is applied to the real world, which is perceived by human eyes, so as to achieve a visual experience beyond reality. Augmented reality technology not only shows the information of the real world, but also displays the virtual information at the same time. The real environment and virtual objects are superimposed on the same picture or space in real time, and the two kinds of information complement and superimpose each other. In visual augmented reality, users use a head-mounted display, such as Google Glass, to multiplex the real world with computer graphics, a...
