User's Manual

PointBlank Product Specification, Rev A
for any input computer source supported by the projector and independent of projector settings
such as keystone, scaling mode, etc.
The PointBlank patterns are not visible to the viewer, except for an increase in the black level and
a small decrease in the red, green and blue lumens. Depending on the DLP sequence approach,
there can be some color distortion of the black level as well. Since the PointBlank patterns affect
the projector contrast and lumens, a non PointBlank mode can also be supported and is
recommended to maintain projector specifications relative to brightness, contrast and color
points.
4 Detailed Description
4.1 PointBlank Hardware
The PointBlank hardware additions to the DDP2431 and DDP2230 reference designs are shown
in
Figure 2 and Figure 3, respectively. They include a PointBlank FPGA inserted between the
DDP ASIC and the DMD, a RF radio transceiver and some changes to the GPIOs. Due to the
additional software memory required for the PointBlank functionality either SRAM or SDRAM is
required for DDP2230 and SRAM is required for DDP2431.
