The display has approximately 141 columns and 44 rows of pixels (plus a few extra as part of a vertical dividing line). But, as can be seen in the pixel layout photo below, those pixels have a rather custom layout which will make it interesting to drive, and probably not worth the effort! Despite apparently being a graphic, rather than character display, the pixels are physically separated into blocks. In the upper half of the display we have 4 blocks 11 pixels wide, 18 blocks 5 pixels wide and one block 7 pixels wide. These are in 3 rows, 8 pixels high, with a gap between the rows. So you could treat the upper half as 3 rows of 27 characters, with a small aberration where the 7 pixel wide block is. The lower half is even stranger, with one blank row, one row as above, then a last row divided into 24 character blocks with borders grouping sets of 6 characters. Not exactly general purpose!
Similar to A270-1101-01, D2C400460, SEVG LCD Board, from IP 230G phones, but they have 39 pins - ShoreTel 230G telephone from 2011
