Embodiment Construction
[0020] First, if figure 1 As shown, a key switch with current analog tactile feedback according to one embodiment of the present invention is illustrated. Such as figure 1 As shown, the key switch includes: a sensor part S1, in which at least one sensor is arranged; a discharge electrode part S2, with a plurality of discharge electrodes E 1 ,E 2 ,...E M ; and a control unit VP which communicates with the sensor in the sensor section S1 and each discharge electrode E in the discharge electrode section S2 1 ,E 2 ,...E M connect. Here, in order to simplify the description of the inventive concept of the present invention, the drawings only schematically show the most important parts for realizing the inventive concept, and the description of other parts is omitted. For example, taking the capacitive sensor adopted by the traditional keyboard as an example, the complete structure of the sensor part S1 should also include the corresponding mechanical structure for the auxili...

The invention relates to a key switch with current simulation touch feedback and a touch sensitive display. The key switch comprises at least one sensor, at least one discharge electrode and a control unit, wherein the sensor detects operation of an operator on the surface of the key switch and generates a first signal; the discharge electrode generates a potential difference point by point in at least one region of the surface of the key switch and outputs a controllable current; and the control unit is connected with the at least one sensor and the at least one discharge electrode and generates a second signal based on the first signal to control the discharge electrode. The touch sensitive display comprises at least one sensor, at least one discharge electrode, a display medium and a control unit, wherein the discharge electrode generates a potential difference point by point in at least one region of the surface of the touch sensitive display and outputs a controllable current; and the control unit generates a second signal based on the first signal to control the discharge electrode. The key switch with current simulation touch feedback and the touch sensitive display can realize current touch feedback and expand the operating feedback ability.
