Abstract
A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The first stage may be provided with straight black masking strips, whereas the second stage may be provided with angled zigzagging black masking strips. The angle of the zigzagging black masking strips and the ratio of the pixel pitch of the second stage to that of the first stage may be selected to maximize optical transmittance while minimizing Moire effects.
