WHITE POINT TUNING FOR A DISPLAY
First Claim
1. A display device comprising:
- a first display element configured to output light,a second display element configured to output light,a third display element configured to output light, andelectronics configured to drive the first, second, and third display elements,wherein each of the first, second, and third display elements has an on-state wherein a reflective surface is positioned at a distance from a partially reflective surface such that the display element reflects incident light, each distance being dependent on a bias voltage,wherein at least one of the bias voltages for the first, second, and third display elements is non-zero in the on-state, and adjustable to control a white point of the display device, the electronics electrically connected to the display elements to provide the at least one non-zero bias voltage.

Abstract
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for tuning the white point of a display device. In one aspect, a display device includes a set of display elements configured to output light and electronics configured to drive the display elements. Each display element can have an on-state where a reflective surface can be positioned at a distance from a partially reflective surface such that the display element can reflect incident light. Each distance can be dependent on a bias voltage. At least one of the bias voltages for the display elements can be non-zero in the on-state, and one or more of the bias voltages may be adjustable to control a white point of the display device. The electronics can be electrically connected to the display elements to provide the at least one non-zero bias voltage.
