Common displays are divided into active displays and passive displays. TFT LCD and AMOLED are active displays. The display is complex and can display rich colors at high resolution. Usually it is an interface such as MCU/RGB/DVI/MIPI/LVDS, which requires a relatively strong processor to drive.

 

Character LCD, Graphic LCD, Segment LCD and PMOLED are passive displays. Such displays are simple in structure and cannot achieve high resolution and large size. Usually, it can only display black and white. Generally, it is an MCU/RGB interface, which is difficult to drive. Simple and relatively cheap.

 

There is a special product is the serial port control display, although it is an active display, but because of the integrated control board, the display content can be controlled by simple instructions, so that the processor with low driving ability can also control the active display.
