The invention discloses a packaging cover plate, comprising a substrate basal plate, wherein the substrate basal plate is divided into a display area and a packaging area, wherein one surface, departing from a light emission side, of the substrate basal plate is provided with at least one light transmitter and at least one light receiver, the light transmitter and the light receiver are both located in the packaging area, the light transmitter can transmit light rays towards to the surface, departing from the light emission side, of the substrate basal plate, the light receiver can receive reflection rays formed by reflecting the light rays transmitted by the light transmitter by the substrate basal plate, and compare the light intensity of the received reflection rays with preset light intensity so as to obtain a comparison result, and the light receiver also can send the comparison result to a control module. The invention further discloses a touch control display panel, a display device and a touch control driving method. The packaging cover plate provided by the invention can reduce power consumption of the display device.
