Abstract
A display has a first array of pixels connected to emit individually-controlled amounts of light onto a second array of pixels. The second array of pixels is connected to pass individually-controllable portions of the light. The display has a controller connected to control the pixels of the first and second arrays of pixels. The controller is configured to control the pixels of the first array of pixels to provide on the second array of pixels an approximation of an image specified by image data; determine a difference between the image and the approximation of the image at individual pixels of the second array of pixels; and control the pixels of the second array of pixels to modulate the approximation of the image according to the corresponding determined differences.
