3D glasses and 3D display system

Abstract

A pair of 3D glasses and a 3D display system are disclosed in the field of display technology. The pair of 3D glasses includes a light polarizing component and a light filtering component. The light filtering component is arranged at the light emitting side of the light polarizing component. The light polarizing component includes a plurality of photonic crystals, each of which is configured to reflect preset-color light among different-color light incident into the photonic crystal to enable the preset-color light to be deflected so as to ensure an optical path difference among the different-color light incident into the light filtering component from the light polarizing component. The light filtering component includes two light filters, one of which is configured to filter out the preset-color light among the different-color light and the other of which is configured to filter out light other than the preset-color light among the different-color light. The present disclosure solves the problem of the relatively high cost of the 3D glasses and reduces the cost of the 3D glasses. The present disclosure is applied for 3D displaying.
