direct-drive image light amplifier (projector) (D-ILA)
The principle of the D-ILA projector differs from the ILA projector in that the image signal is not transmitted electrostatically as a charged image, but by directly driving the liquid crystals. The D-ILA chips are driven directly via array-shaped control lines, hence the name Direct-Drive Image Light Amplifier (D-ILA).
The D-ILA chip consists of the liquid crystal layer, which is controlled via the drive electrode, and a reflective layer. The white light from the projection lamp is dispersed in a hologram color filter and transmitted to the liquid crystals.
Behind the liquid crystals are the color pixels, which reflect the light in the corresponding color. The color intensity is determined by the duration of the color reflection.
Projectors in D-ILA technology have a simpler structure than the ILA projectors. The characteristic features are the high light output and brightness, the high contrast and the enormous image resolution, which may well be Quadruple UXGA( QUXGA) with resolutions of over 3,000 pixels.
D-ILA projectors are available in single-chip and three-chip versions.
