Abstract

A human-machine interface drive module group comprises a circuit board and a shielding cover pressed onto the circuit board; a flat cable interface is arranged on the right side of the circuit board; all interface signals are packaged on a bottom-contact forty PIN flat cable interface; the flat cable interface is connected with an internal circuit of the circuit board; a sixteen PIN contact pin is arranged on the left side of the circuit board, and two PIN panel power supply contact pins are arranged on the upper side; and the flat cable interface includes a forty PIN port arranged in sequence. For assembly of the module group, a flat cable is connected with both a peripheral user interface of a liquid crystal display screen and a peripheral user interface of a touch screen; and the sixteen PIN contact pin, the two PIN panel power supply contact pins and the forty PIN flat cable interface are used for welding the drive module group onto a user PCB in a fixed manner in order to drive the liquid crystal display screen. The human-machine interface drive module group provided by the utility model has the advantages of small size, low power consumption, high stability and rapid processing of texts and images, and avoids the mistake in identifying the cable for connecting a traditional module group with the liquid crystal screen.
