The following derivatives are currently supported: SED1352 SED1354 SED1356 (With/Without BitBlt engine support) SED1374 SED1375 SED13806 Other Epson LCD controllers are very similar and could be covered by this driver as well, but have not been tested. ---------------------------------------------------------------------- Version-Date---Author-Explanation
