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.
