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. 
Sub-nm order fluctuation control of narrowed pitch 2K-GxL™ device for high contrast
We developed a novel 2K vertical resolution device, the 2K-GxL device, for a super real projector, which enabled ribbon pitch to be miniaturized and the contrast ratio to be high simultaneously.Expand
