Sorry for the translation errors. There is a 4004 screen, I cannot use the screen in one piece. It looks like 2 screens on Arduino, but it gets very confusing when you enter the codes.

@ahmet93 you can try my LCD Library. It supports 40x4 character displays in 4bit mode as one display with 4 lines. https://werner.rothschopf.net/microcontroller/202012_arduino_liquid_crystal_4004_en.htm
