High contrast micro display with off-axis illumination

摘要

A liquid crystal display of improved contrast is provided. Image contrast is determined by the ratio of light from the display pixels that are in an on state to the light from the display pixels that are in an off state. The disclosed system improves on the image contrast by selecting the illumination direction and the panel orientation in such a way as to minimize the amount of light entering the viewing field that is due to scattered and/or diffracted light from the fine features of the display panel.
