illuminate the backlight even if it is not connected. If you need to
turn off the backlight, you need to connect BLK to low level or directly
to ground.
MISO is the output signal of the
screen. If you do not need to read the information of the screen, this
pin can be disconnected. A minimum of 4 IO ports are required to
operate.
