The light engine includes the DLP4500 0.45-inch DMD with 1039680 mirrors, each 7.6 µm, arranged in
912 columns by 1140 rows with the diamond pixel array geometry and configuration (see Figure 1-3 and
Figure 1-4). Due to the diamond pixel configuration, the array produces smooth diagonal lines, with jagged
vertical and horizontal lines, as shown in Figure 1-5. Two options exist to produce the vertical and
horizontal lines: use every row or column, or use every other row or column. When every row or column is
used, a more thick line is projected. When every other row or column is used, a more faint line is
projected.
