Abstract
Aspects of the disclosure provide a liquid crystal (LC) device, a head mounted display (HMD) system, and a method of tuning the HMD system. The LC device includes a first electrode structure disposed on a first substrate with an elliptical shape. The first electrode structure includes parallel first segments connected by second segments. The LC device includes a plurality of first control electrodes electrically coupled with the first electrode structure. The plurality of first control electrodes is configured to form LC lenses at different positions. Each of the LC lenses at the different positions is formed when electrical signals are applied to a subset of the plurality of first control electrodes that is associated with the respective LC lens. The LC device includes a second electrode structure disposed on a second substrate and at least one second control electrode electrically coupled with the second electrode structure.
