This time I'll talk about how the control flow from the MCU to the LCD is how our bitmap data is displayed on the LCD. Before we learned that the LCD display is implemented by dynamic scanning, each time a full line is displayed, each line in a frame is scanned once, so that there is a circuit to control the output voltage on the row and column, this circuit is the LCD driver, and the output of the driver a
