- 15. An apparatus according to claim 13, further including
a timer for periodically flashing the display.
- 16. An apparatus according to claim 13, further including
a noise generator for generating a noise signal having two-color components and for delivering the noise signal to the video driver process for processing the noise signal with the three color components of the image.
- 17. An apparatus according to claim 16 including a dynamically changing filter for introducing variation into the translation of the relative brightness of the three color components to relative brightness for the two-color elements.
- 18. An apparatus according to claim 13, wherein the process includes
a process for summing the brightness for a first one of the three color components with half the brightness of a second one of the three color components to determine the relative brightness for a first color component of the display, and summing the brightness for a third color component with half the brightness of the second color component to determine the relative brightness for the second color component of the display.

a process for determining the long wavelength component of a two color display by multiplying the numbers representative of relative brightness of three colors in a three color display by values representative of the effect of a longwave pass filter, and summing the generated numbers to provide the relative brightness of that point in the long wave component of the two color display, and a process for determining the short wavelength component of a two color display by multiplying the number s representative of relative brightness of three colors in a three color display by values representative of the effect of a shortwave pass filter, and summing the generated numbers to provide the relative brightness of that point in the short wave component of the two color display.
- 20. An apparatus according to claim 13, further comprising a border having a color that is the combination of the first and the second colors or the two color display and being arranged substantially around the periphery of the display.
- 21. An apparatus to claim 20, wherein the border comprises part of the image displayed to the user.
- 22. An apparatus according to claim 20, wherein the border comprises colored border formed as an edge around the two-color display.
- 23. An apparatus according to claim 20, wherein the border comprises a yellow border of spectral yellow or yellow formed from red-green components.
- 24. An apparatus according to claim 13, wherein the two-color display include a display selected from the group consisting of an LED display, and LCD display, a light emitting polymer display and a CRT display.
