Abstract
Described are improved approaches to implement color sequential displays that can mitigate problems with conventional display technologies. Color-breakup is mitigated by modifying the original color channels and adding one or more additional color channels derived from the original ones.
Claims27
A system, comprising:
- a light source having a red light source, a green light source, and a blue light source;
- a display having at least one pixel corresponding to image data formed from light generated from a red channel for the red light source, a green channel for the green light source, and a blue channel for the blue light source;
- and
- a controller that controls operation of the light source and the display to display the at least one pixel, the controller modifying the red channel to create a reduced red channel, modifying the green channel to create a reduced green channel, and modifying the blue channel to create a reduced blue channel, wherein the controller forms a white channel from portions removed from the red channel, the green channel, and the blue channel, such that the at least one pixel is formed by sequential presentation in any order of the white channel, the reduced red channel, the reduced green channel, and the reduced blue channel.

A method, comprising:
- receiving instructions to display on a display device at least one pixel corresponding to image data formed from light generated from a red channel for a red light source, a green channel for a green light source, and a blue channel for a blue light source;
- modifying the red channel to create a reduced red channel;
- modifying the green channel to create a reduced green channel;
- modifying the blue channel to create a reduced blue channel;
- generating a white channel from portions removed from the red channel, the green channel, and the blue channel;
- and
- displaying the at least one pixel by sequential presentation in any order of the white channel, the reduced red channel, the reduced green channel, and the reduced blue channel.

A computer program product embodied on a computer readable medium, the computer readable medium having stored thereon a sequence of instructions which, when executed by a processor causes the processor to execute a method comprising:
- receiving instructions to display on a display device at least one pixel corresponding to image data formed from light generated from a red channel for a red light source, a green channel for a green light source, and a blue channel for a blue light source;
- modifying the red channel to create a reduced red channel;
- modifying the green channel to create a reduced green channel;
- modifying the blue channel to create a reduced blue channel;
- generating a white channel from portions removed from the red channel, the green channel, and the blue channel;
- and
- displaying the at least one pixel by sequential presentation in any order of the white channel, the reduced red channel, the reduced green channel, and the reduced blue channel.
