5.5 - Expanded Mode
If your pixels do not have a clock line, you may optionally activate expanded mode on
the controller, via the Management Interface. In expanded mode, the clock lines are
used as data lines instead. This means the controller effectively has twice as many
pixel outputs (8), but half as many pixels per output can be run.
Compared to pixels with a clock line, pixels that only use a data line have the
potential to lower the maximum achievable refresh rate in a pixel system. If a pixel
system is using data-only pixels, then the refresh rates will typically be improved by
using expanded mode. Enabling expanded mode allows for twice as many data
outputs, so the same number of pixels can be spread out over these outputs,
resulting in a large improvement to refresh rate. This becomes more important as the
number of pixels per output increases.
The pinout for expanded mode is shown in Figure 10 below.
Note: Mapping of these pixel outputs in the Management Interface will appear as
follows:
l
Management Interface Output 1:Pixel output 1 - Data 1,
l
Management Interface Output 2:Pixel output 1 - Data 2,
l
Management Interface Output 3:Pixel output 2 - Data 1,
l
Management Interface Output 4:Pixel output 2 - Data 2, etc.
