The HEP DMD: a new DLP pixel optimized for performance

The High Efficiency Pixel (HEP) is the first new pixel node for Texas Instruments DLP® Products since 2013. It gives DLP Products a high efficiency Digital Micromirror Device (DMD) that has the area and tilt to support high brightness LED illumination with high contrast and a wide color gamut. HEP was designed to provide a cost-effective solution utilizing CMOS yield learning from prior pixel nodes and DMD superstructure designed specifically with high stiction margin operation. This results in a cost effective, high reliability DMD that supports high optical power densities. The pixel node supports a whole product family of the key resolutions: 1080p (or full HD), WUXGA, and 4k UHD. This paper presents the HEP requirements and design methodology and includes testing results and market acceptance.
