Modern intelligent indicator display
Serial indicator displays with a serial interface are called "serial display". The 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 display, graphics and icons are also displayed via the serial interface.
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.
