I came across your post while searching for sources for this 16x2 OLED display. I acquired some of these displays a year or so ago branded under Vishay (p/n OLED-016002B). They are Winstar WS-0012 controller based and not HD44780 compatible. Initialization is the most elusive task, and here's the command sequence that has worked for me:
0x0028\10
0x0013\10
0x0003\10
0x0029\10
0x0068\10
0x0000\10
0x0001\10
0x0016\10
0x0006\10
0x000C\10
0x0002\10
The "\10" designates truncating the 16 bit commands to 10 bits as I'm using the display in serial SPI mode (each command is sent separately with CS). I pause 1 msec between commands, except for the clear display 0x0001 where I pause 10 msec. In SPI mode, I "OR" 8-bit ASCII characters with 0x0200\10 to create 10-bit writes. 4-bit/8-bit parallel mode should work using this same initialization sequence.
