D-ILA

Digital Direct Drive Image Light Amplifier. Technology developed by Hughes-JVC for video projection up to large screen size for home theaters. Digital images are displayed by a CMOS chip which has a reflective liquid-crystal surface where electronic signals are directly addressed to the image modulator. The image pixel information is addressed to a matrix of ‘transistor’ cells beneath the liquid crystal which directly responds to voltage level; the gray scale is determined by the voltage set on each pixel. The reflection of the projector lamp light focused on the chip produces an image. The technology has been used up to cinema-screen size and can display 4K resolution.
