• Bypass LUT – when selected this option causes the lookup table to be bypassed.
Selecting to bypass the lookup table results in a power saving as the lookup table section
of the SED1374 is powered down when this option is selected.
This option is only applicable for monochrome displays. If a color panel is selected this
option is disabled.
When the lookup table is not enabled then display intensities are dependent on the
values in the lookup table. A smaller numerical value in display memory may be
displayed with a greater intensity than a larger value.
When the lookup table is bypassed the colors displayed on the panel are directly propor-
tional to their memory value. (i.e. at 4 bit per pixel; 00h will display as black and 0Fh
will display as full intensity)
