The Grating Light Valve GLV™ technology has been used in an innovative system architecture to create a high resolution projected image by optically scanning a linear array of GLV pixels. We will discuss optical and electrical techniques used to optimize the performance of this unique architecture in terms of overall image quality, uniformity and repeatability.

Commercial digital image interchange standards (such as sRGB and BT.709/BT.1886) are universally based upon additive RGB. However, frame‐sequential color projectors (such as 1‐DLP) projectors have for many years used a white segment that affords higher luminance for white and high‐luminance/low‐chroma colours (sometimes called “white boost”), at the expense of introducing large color errors with respect to the interchange standard. In this work we show that luminance contours characterize loss of color accuracy, and we estimate available color gamut at the interface of created content and display.
