age Quality D-ILA™ - Projector Device Innovation D-ILA™ Structure The D-ILA™ device is a reflective type of LCD that delivers a higher aperture ratio (more than 93%) than a transmissive LCD panel, and is comprised of groups of pixels which correspond to each image dot. Also unlike conventional transmissive LCD panels (in which the driving transistor is mounted on the same surface as the pixels), the D-ILA™ʟs driving IC substrate is located behind the liquid crystal layer. As a result, the D-ILA™ device can achieve higher brightness and higher resolution at the same time. In addition, thanks to the vertical alignment ("homeotropic" structure) of the liquid crystal layer, projected images also have much higher contrast.
