DP3246 - a new driver IC not working as expected

Has anybody come across new 64x64 1/16 LED matrix displays coming in from SZLightall that have the newer DP3246 driver IC on them? We got these in and they don’t seem compatible with the more common Chipone ICN2037 and Macroblock MBI5124. Would anybody have a datasheet for the DP3246 they can point me at, or even know who DP semiconductor are as I’m unable to find them anywhere? Thanks a lot.
