Block Diagram
Figure 1. The grayscale data are input onto the DM163 by the SIN pin and transferred
according to the synchronous clock DCK. Meanwhile, in order to separate the data
into two groups, SELBK is designed as a switch control pin. When a sequence of
data is already transferred onto the chip, the LAT_B=”H” is set to convey it into the
comparator unit.
determine the PWM control signal to display varied luminance at driver output. The
Rext resistors are able to set diverse output current levels. The detailed schematic
of each channel is shown as Figure 2.
