I/Os stand for In/Outs. That is the connections between the LCD and the processor. Each type of interface has its own number of I/Os. Parallel can have 4 or 8 or more. RGB can have 16 or 24 or other even numbers. SPI normally has 3 or 4.



Sometimes you may have a limited number of I/O’s left on your processor and need a limited number to drive your LCD. SPI and I2C have the lowest number of I/O’s, but they are not as fast as other interfaces for video and other applications.
