* '''Time-Multiplexed Displays:''' Different views or directional illumination patterns are presented rapidly in sequence. If cycled faster than human perception, this creates the illusion of a continuous light field. Can be combined with other techniques like directional backlighting.<ref name="Liu2014OSTHMD">Liu, S., Cheng, D., & Hua, H. (2014).
