Description
The STE2102 is a low power CMOS single-chip
TFT controller/driver featuring an extremely low
current consumption thanks to an innovative
charge pump architecture. Designed to drive a
240 rows by 320RGB columns 262k colors
graphic display, with amplitude modulation
method, the STE2102 provides all the necessary
functions in a single chip, including on-chip gate
drivers supply, source drivers supply and source
reference voltages generators, resulting in a
minimum of externals components.
STE2102 features an high-speed RGB interface
to transfer flicker-free video data, an 8-bit YCrCb
digital video interface and several bi-directional
serial interfaces to configure the display.
The IC is designed to operate with both traditional
Cap-on-CE and with Cap-On-Gate panels.
