Just feeling like want to drive some LCD today, so here we go. They are all typical controller-less monochrome STN LCDs, and I have used these code many times. The first one is the LM081HB1T, 8.1" 640x240 negative mode STN. Due to the limited RAM of STM32F1 (64KB), I could only do 320x240x4bit mode or 640x240x3bit mode. The following shows it in full resolution.
Then in 4bpp mode:
The next one is the Truly M320240-19, the size is 5.1", resolution 320x240, positive mode FSTN, comes with CCFL backlight.
The display quality is rather good, however the screen greyscale response is quite non-linear. I had to manually compensate that in the image, but resulting in fewer usable greyscale levels.
M320240-19
