Unfortunately I'm not that familiar with display manufacturers and panel assemblies. Most of the what I presume to be panel names were gleaned from online screen replacement photos; those don't ever include the DDIC name. Those mostly come from the DTS though isn't mentioned exactly for every phone (only the first two in the DTS name). > They are clearly using the S0FEF01-M display controller. So you're implying or certain that these panel names here are always bundled with exactly the same controller (making the SOFEF01 part "redundant" in the compatible)? Also, divergence of the driver commands got significant with the last two panels / three phones, though that might be down to vendor configuration/calibration. - Marijn > Yours, > Linus Walleij
