High aperture AMLCD with nonparallel alignment of addressing lines to the pixel edges or with distributed analog processing at the pixel level

摘要

An approach for constructing active matrix liquid crystal light valves having very high aperture ratio is described. This is achieved by a burying the pixel addressing elements beneath a planarized array of nearly contiguous pixel electrodes and minimizing the footprint of opaque structures in the light valve. Undesirable field-induced disclinations and deformations of the liquid crystal are minimized by shielding the addressing structures with the pixel electrodes. Embodiments are provided which utilize the approach to improve transmittance, image quality, yield, design flexibility and functionality of the display.
