Embodiment Construction

[0024] This disclosure describes methods to achieve improved color sequential display. As noted above, existing color sequential display technologies suffer from the possibility of color separation, as different color primaries are rendered at different times. If the viewer's head or eyes move during presentation of the desired image, different fields will fall on different locations on the viewer's retina, causing image artifacts to appear to the viewer of the display.

[0025] To explain, consider Figure 1A and Figure 1B A color sequential display 100 is shown. For these types of displays, an image is represented by a set of color channels, such as red, green, and blue. The controller 130 is used to generate control signals for controlling the generation of different color channels in the color sequential display 100 . Each pixel produced by color sequential display 100 may correspond to a red channel 150a, a green channel 150b, and a blue channel 150c.

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.

Description

Background technique [0001] The basis of many modern display technologies is the premise of the fact that the range of human perceivable colors can be obtained by adding three or more suitably chosen color primaries, usually red, green and blue ("RGB"). to express. These primary colors can be added in various ways to reproduce a wide variety of different colors. [0002] Some display technologies provide colors sequentially, for example, producing a red image, then a green image, then a blue image. This display technique is commonly referred to as "color sequential", "field sequential" or "field sequential color" (hereinafter collectively referred to as "color sequential"). Color sequential displays work because of visual persistence. If the different color images (fields) are presented in sequence fast enough, the human eye merges them into a full-color image. Popular examples of color sequential displays include certain LCOS (liquid crystal on silicon) panels and DMDs (d...
