UniPixel (UNXL -17%) tanks again after SA contributor Seth Shaw posts pictures of UniBoss touch sensor film that he considers indicative of poor quality. Seth: "The product does not work. The lines are too visible. No consumer electronics company would approve this..." He also shows a picture of a UniBoss demo unit with broken lines, and says talks with engineers and ex-employees revealed doubts about UniPixel's ability to mass-produce UniBoss. An industry consultant and engineers at Synaptics, Texas Instruments, and private Touch International all reportedly made technical complaints; they often related to visible lines.
