Patent number: 11841586Abstract: A liquid crystal display has position-adjustable light sources. The light sources may be lamps, LEDs, or other emissive components. The light sources, however, are movable to adjust the locations or positions of their light outputs. The light sources ride upon electromagnet carriers. When currents are applied to the electromagnet carriers, each electromagnet carrier creates a corresponding magnetic field. The magnetic fields cause neighboring electromagnet carriers to attract or to repel, depending on the magnitude/polarity of the currents. The lateral and vertical positions of the electromagnet carriers may thus be adjusted by varying their respective currents and magnetic fields. Because the light sources ride on the electromagnet carriers, the light sources may be moved to refine an image generated by the liquid crystal display. The light sources, for example, may be moved to improve white/black contracts to reduce halo-effects.Type: GrantFiled: July 21, 2022Date of Patent: December 12, 2023Assignee: Dell Products L.P.Inventors: Ching-Feng Chen, Chao-Kai Huang, Yi-Fan Wang, Meng-Feng Hung, Wei-Ching Hsu

Patent number: 11619830Abstract: To enable a display to display different content to different viewers, a display may include a time-sequential directional backlight unit. The backlight unit may emit light in different directions in different configurations. In a first state, the backlight unit emits light at maximum brightness in a first direction. In a second state, the backlight unit emits light at maximum brightness in a second direction that is different than the first direction. The backlight unit may repeatedly and rapidly switch between the different states. The first direction may be towards a first viewer whereas the second direction may be towards a second, different viewer. Therefore, each viewer receives backlight in one of the configurations and does not receive backlight in the other configuration. In synchronization with the backlight unit, the liquid crystal display panel may repeatedly switch between displaying content for the first viewer and displaying content for the second viewer.Type: GrantFiled: March 25, 2022Date of Patent: April 4, 2023Assignee: Apple Inc.Inventors: Hao Chen, Juan He, Rong Liu, ByoungSuk Kim, Jun Qi, Yi Huang
