Optical lens having a tunable focal length and display device including the same

Abstract

An optical lens having a tunable focal length and a display device including the same are provided. The optical lens includes a control electrode including a plurality of electrode elements, an electroactive material layer provided on the control electrode, and a common electrode spaced apart from the control electrode. The electroactive material layer is interposed between the common electrode and the control electrode. The optical lens includes a plurality of bus sets, each bus set of the plurality of bus sets including a plurality of buses, wherein the plurality of bus sets include a first bus set and a second bus set, the first bus set is configured to apply a first voltage to the plurality of electrode elements to generate a first phase profile of light, and the second bus set is configured to apply a second voltage to the plurality of electrode elements to generate a second phase profile of light.
