Description
The STV8105 is a low-power, controller/driver
“combo” IC for OLED displays. The STV8105
supports 256 columns by 72 rows with 16 levels
of gray for monochrome and 2 x 128 columns by
72 rows with 16 levels of gray for “two” color
displays. It can control a display of 128 columns
by 72 rows or 256 columns by 36 rows with 64
levels of gray in monochrome mode.
The STV8105 provides all necessary functions in
a single chip, including on-chip supply control and
bias current generators, resulting in a minimum of
external components and in very low-power
consumption.
The STV8105 communicates with the system via
fully configurable interfaces (parallel or serial) to
ease interfacing with the host microcontroller. The
STV8105 has a set of command and control
registers that can be addressed by these
interfaces.
