Serial modern intelligent indicator displays
Displays or displays with a serial interface are called "serial indicator displays". The serial interface can now be an RS-232, an SPI or an I²C bus. Controlled in series, a few pins are required on the controller and can therefore also bridge longer distances (RS-232 / RS-485). Functions such as deleting or positioning cursors, with graphics-capable displays, graphics and icons are also displayed via the serial interface.
Serial display modules are available as text and graphic displays. Here, the data is transmitted bit by bit, i.e. serially with a wide variety of baud rates or clock rates.
