Abstract: A control device for an electroluminescent touch-control display panel is described having a display driving circuit board, a touch-control driving circuit board, a lighting circuit board and a switching circuit board. The lighting circuit board provides a first reference signal to the touch-control driving circuit board. During the display period, the touch-control driving circuit board gates the first reference signal and transmits it to the display driving circuit board which then transmits the first reference signal to a cathode in the touch-control display panel to realize display. During the touch-control period, the touch-control driving circuit board gates an excitation signal and transmits it to the display driving circuit board which then transmits the excitation signal to the cathode and transmits a feedback signal to the touch-control driving circuit board, and the touch-control driving circuit board determines a position of touch control in accordance with the feedback signal.
