Description

Display device

The present disclosure relates to a display device. More specifically, there is a display panel relating to a display device.

In order to drive the display module operation in the display device, the system circuit board is connected to the circuit board (display circuit board) of the display module via the wires behind the display module (the other side of the display screen side). Therefore, a connection port for the power supply line connection is provided correspondingly on the system board and the display circuit board.

The above connection method will cause some problems.
