Abstract: A touch device and a touch method of a flexible OLED display apparatus are provided. The touch method includes: acquiring a variation value of a cathode voltage when the display mode is switched; comparing the variation value of the cathode voltage with a preset threshold value, and when the variation value of the cathode voltage exceeds the preset threshold value, increasing the emitter electrode voltage of the touch electrode layer in the Flexible OLED display apparatus. When the cathode voltage changes due to the display mode switching, if the variation value thereof exceeds the preset threshold value, the voltage output amplitude of the emitter electrode is increased, so as to keep the amount of variation of the electric quantity of the receiver electrode constant, thereby keeping the electric quantity of the node capacitance between the emitter and receiver electrodes constant and enhancing the consistency of touch performance.
