Abstract: Proposed is a laterally multilayered dielectric elastomer actuator and a method of manufacturing the same. The actuator includes a polymer frame, an electrode, and a dielectric elastic portion. The polymer frame includes a first pattern with a first comb shape of a predetermined thickness and a second pattern with a second comb shape of a predetermined thickness. The electrode includes a first electrode formed on a portion of the first pattern and a second electrode formed on a portion of the second pattern. The dielectric elastic portion is interposed between the first electrode and the second electrode and contains a dielectric elastomer. Since the actuators can be laterally stacked, a multilayered actuator in which a large number (several to several thousands) of dielectric elastomer actuators stacked can be manufactured in the form of a very thin film (

Abstract: An optical see-through display apparatus includes an image output module, a display panel, an optical shutter panel to adjust a transmittance of an external light for each of R, G, and B colors. The display apparatus includes an optical sensor to measure a color of the external light. The display apparatus includes a processor that generates R, G, and B shutter data through a first compensation algorithm. The first compensation algorithm is operated to: compare a color of a mixed virtual image with a color of a target mixed virtual image, and when a color difference therebetween is a threshold value or less, designate a transmittance of the optical shutter panel as a candidate transmittance, and select a candidate transmittance implementing the mixed virtual image most similar to the target mixed virtual image, and generate the R, G, and B shutter data corresponding to the selected candidate transmittance.
