Abstract
A video display device comprises an arrangement of light sources for displaying video content. Further, the video display device comprises a controller that is configured to control the light sources to display the video content. Further, the controller is configured to control the light sources according to strobe control information to perform a strobe effect by periodically switching the light sources between a first state and a second state, e.g., between a state of low brightness and a state of high brightness.
Claims12
A video display device, comprising:
- an arrangement of light sources, wherein the light sources are individually-controllable;
- an interface configured to receive video content and strobe control information that indicates a first frequency at which the light sources should be switched between a first state and a second state, wherein the first frequency indicated in the strobe control information is independent of a frame rate of the video content;
- and
- a controller configured to control individual light sources within the arrangement of light sources to display the video content according to the strobe control information, wherein one or more light sources included in the arrangement of light sources are assigned to represent each individual pixel of the video content, wherein the controller is further configured to cause a strobe light effect to be displayed by periodically switching one or more of the individual light sources between the first state and the second state at the first frequency, wherein the strobe light effect produces flashes that are visually perceptible to a viewer, and wherein the first frequency is included in a range of frequencies such that switching the one or more of the individual light sources between the first state and the second state at the first frequency produces the flashes that are visually perceptible to the viewer,
- wherein, in the first state, light emissions by the individual light sources are controlled to display a frame corresponding to the video content, and in the second state, light emissions by the individual light sources are controlled based on a level that is defined independently of the video content.

A video controller, comprising:
- an interface for at least one video display device that includes an arrangement of light sources for displaying video content, wherein the light sources are individually-controllable,
- wherein the interface is configured to send the video content and strobe control information that indicates a first frequency at which the light sources should be switched between a first state and a second state to the at least one video display device, wherein the first frequency indicated in the strobe control information is independent of a frame rate of the video content, wherein the at least one video display device causes the video display device to control individual light sources within the arrangement of light sources to produce a strobe light effect to be displayed by periodically switching one or more of the individual light sources between the first state and the second state at the first frequency, wherein the strobe light effect produces flashes that are visually perceptible to a viewer, wherein one or more light sources included in the arrangement of light sources are assigned to represent each individual pixel of the video content, and wherein the first frequency is included in a range of frequencies such that switching the one or more of the individual light sources between the first state and the second state at the first frequency produces the flashes that are visually perceptible to the viewer,
- wherein, in the first state, light emissions by the individual light sources are controlled to display a frame corresponding to the video content, and in the second state, light emissions by the individual light sources are controlled based on a level that is defined independently of the video content.
A system, comprising:
- at least one video display device that includes an arrangement of light sources for displaying video content, wherein the light sources are individually-controllable, and an interface configured to receive the video content and strobe control information that indicates a first frequency at which the light sources should be switched between a first state and a second state, wherein the first frequency indicated in the strobe control information is independent of a frame rate of the video content, wherein the at least one video display device is configured to control individual light sources within the arrangement of light sources to display the video content according to the strobe control information, wherein one or more light sources included in the arrangement of light sources are assigned to represent each individual pixel of the video content, wherein the at least one video display device is further configured to produce a strobe light effect to be displayed by periodically switching one or more of the individual light sources between the first state and the second state at the first frequency, wherein the strobe light effect produces flashes that are visually perceptible to a viewer, and wherein the first frequency is included in a range of frequencies such that switching the one or more of the individual light sources between the first state and the second state at the first frequency produces the flashes that are visually perceptible to the viewer;
- and
- a video controller configured to send the strobe control information to the at least one video display device,
- wherein, in the first state, light emissions by the individual light sources are controlled to display a frame corresponding to the video content, and in the second state, light emissions by the individual light sources are controlled based on a level that is defined independently of the video content.
1 more element
A method for controlling a video display device, comprising:
- receiving video content and strobe control information that indicates a first frequency at which light sources should be switched between a first state and a second state, wherein the first frequency indicated in the strobe control information is independent of a frame rate of the video content;
- controlling an arrangement of light sources of the video display device to display the video content, wherein the light sources are individually-controllable, and wherein one or more light sources included in the arrangement of light sources are assigned to represent each individual pixel of the video content;
- and
- according to the strobe control information, controlling individual light sources within the arrangement of light sources to perform a strobe light effect to be displayed by periodically causing one or more of the individual light sources to switch between the first state and the second state at the first frequency, wherein the strobe light effect produces flashes that are visually perceptible to a viewer, wherein the first frequency is included in a range of frequencies such that switching the one or more of the individual light sources between the first state and the second state at the first frequency produces the flashes that are visually perceptible to the viewer,
- wherein, in the first state, light emissions by the individual light sources are controlled to display a frame corresponding to the video content, and in the second state, light emissions by the individual light sources are controlled based on a level that is defined independently of the video content.
