  • Abstract
    This paper presents a GxL device that exhibits an extremely high contrast ratio. We achieved a very high device contrast ratio of 34700 by optimizing the design of the posts that support the ribbons and flattening the sacrificial layer. By miniaturizing the chip and improving the packaging, we were able to shrink the GxL module by 75%. Dramatic image quality improvement of the GxL projector system was confirmed. No degradation of the GxL device was observed after a temperature cycling test.
