1. A display apparatus, comprising:

  • a control unit setting an image display period and a touch sense period of the display apparatus in a cycle time according to demand of the image display period and the touch sense period, and generating image display data, a first control signal and a second control signal;

    the first control signal is employed for controlling image display and the second control signal is employed for controlling touch sense;

    a sum of time of the image display period and time of the touch sense period is equal to the cycle time, and the image display period and the touch sense period are alternately changed;

    wherein duration of the image display period and the touch sense period within the cycle time are changeable by the control unit;

    a display panel, employed for displaying images according to the image display data and generating a touch sense signal according to the first and second control signals, and transmitting the touch sense signal to the control unit;

    the display panel comprising;

    a substrate;

    a thin film transistor array layer, at least comprising a first conductor layer and a second conductor layer;

    an anode layer;

    an organic light emitting diode layer;

    a cathode layer, wherein the cathode layer covers a display area of the display panel;

    a sequence of the said layers from bottom to top in the display panel is the substrate, the second conductor layer, the first conductor layer, the anode layer, the organic light emitting diode layer and the cathode layer;

    wherein the cathode layer is divided into a first cathode block and a second cathode block according to a predetermined pattern, the first cathode block and the second cathode block are electrically coupled together, and wherein direct touch of the first cathode block or the second cathode block by a user generates the touch sense signal in the touch sense period;

    the cathode layer, the organic light emitting diode layer, the anode layer and the thin film transistor array layer are cooperated and controlled by the first control signal to display the images, in the display area, in the image display period;

    wherein the first conductor layer comprises a first conductor block and a second conductor block, and the first cathode block and the second cathode block are electrically coupled via the second conductor block;

    wherein the anode layer comprises a main part, a first conducting part, and a second conducting part, the main part and the first conductor block are directly coupled, the first conducting part is directly connected between the first cathode block and the second conductor block, and the second conducting part is directly connected between the second cathode block and the second conductor block.
