Abstract
A pattern is formed on an optical device, where the optical device includes a plurality of pixel elements. Each pixel element has a stack of layers that includes a colour control layer and a brightness control layer superposed over each other. For each of one or more of the pixel elements: energy is deposited into the colour control layer to change an effect of the colour control layer on the colour of light, and energy is deposited into the brightness control layer to change an effect of the brightness control layer on the intensity of light.
