In a method of correcting a desired color of a pixel to be displayed in an optical see-through display, a binned-display profile of prescribed colors arranged to be rendered by the display include background colors added to it so that the desired color can be matched to a closest one of the resulting predicted color profile of colors which are predicted to be perceived by a user. The display is then instructed to display the prescribed color which corresponds with the closest matching predicted color such that an observer substantially perceives the desired color. Typically the desired color is only compared to a subset of the predicted colors for efficiency. Additional corrections may take place to improve contrast of graphical content compared to the background in some instance.

A reflective filter serving as a multi-bandpass filter for a light source configured to emit light in a plurality of color primary wavelengths to improve color purity. The addition of a reflective / recirculation assembly reinforces and recirculates light not passed by the multi-bandpass filter back into a desired spectrum, which is subsequently passed by the multi-bandpass filter, or converts light not passed by the multi-bandpass into electrical energy for use by the system. The reflective filter, solely or along with the recirculation assembly, can be placed adjacent a conventional light source. Alternatively the multi-bandpass filter and the recirculation assembly can be placed in a modified light source, or placed in an optical stack along the path of light emission. Collimating structures that enforce the light into desired incident angle of attack onto the reflective filter can be included to enhance the efficiency of the reflective elements in the assembly.
