Abstract

An electronic device may include a stereoscopic display with a plurality of lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have different viewing zones that account for horizontal parallax as a viewer moves horizontally relative to the display. The display may be dimmed globally, blurred, and/or composited with a default image based on the detected vertical position of the viewer. The display may render content that compensates for the real-time vertical positions of multiple viewers.

Claims21

Dependent claims

An electronic device comprising:

a display that includes an array of pixels and a lens film formed over the array of pixels, wherein the lens film spreads light from the display in at least a horizontal direction;
at least one sensor configured to obtain sensor data;
and
control circuitry configured to:
determine first eye position information for a first viewer from the sensor data, wherein the first eye position information includes a first vertical eye position and a first horizontal eye position;
determine second eye position information for a second viewer from the sensor data, wherein the second eye position information includes a second vertical eye position and a second horizontal eye position;
and
render content for the display, wherein the rendered content includes first content for the first viewer that is based at least partially on the first vertical eye position and second content for the second viewer that is based at least partially on the second vertical eye position.
