Abstract
A display device employs a patterned quantum rod layer having pixel elements driven by pixel splitting to generate a privacy viewing mode. The display device includes a patterned quantum rod layer having first pixel elements including first quantum rods wherein the first quantum rods are aligned in a first alignment direction, and second pixel elements including second quantum rods wherein the second quantum rods are aligned in a second alignment direction different from the first alignment direction. An electronic controller is configured to perform pixel splitting whereby the electronic controller drives the first pixel elements and the second pixel elements such that the patterned quantum rod layer has an off-axis luminance different from an on-axis luminance to generate a privacy viewing mode. The first alignment direction may be oriented 90° relative to the second alignment direction.
