The DMD Panel used in DLP Projectors consists of several hundred thousand micro mirrors. As with other visual display
elements, the DMD Panel may include a few bad pixels. Samsung and the DMD Panel manufacturer have a rigid, bad pixel
identification and limitation procedure in place and products will not exceed the maximum number of bad pixels set by our
standards. Rarely, non-displayable pixels may exist, however it does not affect the picture quality nor the lifespan of the
product.
