Continuing a tradition of display excellence, Texas Instruments has invented SmoothPicture Technology that enables high resolution digital display systems at an affordable price point. These new displays use DMDs with a new diamond pixel layout pattern. In order to achieve full orthogonal resolution, Texas Instruments has coupled the unique diamond DMD architecture with an optical actuator to implement SmoothPicture Technology.
The technology displaces the optical image by ½ pixel thus utilizing each DMD mirror to display two pixels on the display face. The SmoothPicture technology results in a smooth film-like image without visible pixelization while displaying all of the image data supplied by the video source.
