Abstract
An eye-mounted display includes a femtoprojector, which includes a backplane and a frontplane. The backplane receives data (e.g., data packets) that specify the image to be projected by the eye-mounted display. It converts this data to drive signals (e.g., current) to drive the frontplane. The frontplane contains an array of light emitters (e.g., LEDs) that produce light according to the drive signals, thus generating the desired image. In one approach, the image is deconstructed and transmitted to the backplane as needed as microframes which are displayed asynchronously and only for regions where the image has changed, rather than continuously scanning full picture frames at the full frame rate. In another aspect, the femtoprojector has variable pitch between adjacent light emitters.
