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 present invention relates to a button switch and touch-sensitive display having current simulated touch feedback. The button switch comprises: at least one sensor, for detecting an operation of an operator on the surface of the button switch and generating a first signal; at least one discharge electrode, for generating a potential difference point by point in at least one region on the surface of the button switch and outputting a controllable current; and a control unit, connected to the at least one sensor and the at least one discharge electrode and for generating 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, for generating a potential difference point by point in at least one region on the surface of the touch-sensitive display and outputting a controllable current; a display medium, and a control unit, for generating a second signal based on a first signal to control the discharge electrode. The button switch and the touch-sensitive display in the present invention can realize current feedback of touch and extend the operation feedback capability.
