gm5115/25 Preliminary Data Sheet
4.13.2 Programmable Row Driver Interface
The gm5115/25 row driver interface supports 2 and 3 voltage row drivers.
The row driver interface consists of the following signals. The starting time and pulse-width of
each are fully programmable.
RSP2 – Row Starting Pulse for 2 voltage Row Driver
RSP3 – Row Starting Pulse for 3 voltage Row Driver
ROWCLK – Row/Vertical shift clock
ROE – Row Output Enable or Row Blank Time or Gate Driver Output Enable. This signal is
used to control RC discharge time. Note that some vendors support three ROE’s for this function
to avoid 2 lines being activated at the same time (ROE2 and ROE3 are optionally available on
pins GPIO9 and GPIO10). The polarities of ROE, ROE2 and ROE3 are programmable. These
signals can be blanked during horizontal and/or vertical blanking to reduce power. In addition,
ROE, ROE2 and ROE3 may be staggered.
ROWCLK, ROE, ROE2 and ROE3 have programmable polarities and can be blanked during
horizontal and/or vertical blanking period (programmable) to reduce power. Note that ROE2 and
ROE3 can be used to drive GV and GVOFF signals required by some row driver ICs.
See the gm5115/25 programming guide (C5115-DSR-01) for details regarding row driver
programming.
