Abstract:
A keyboard apparatus including a key module and a detection circuit is provided. The key module includes a plurality of keys, a plurality of scan lines and a plurality of return lines. The scan lines and the return lines are crossed to each other and respectively coupled to the keys. The detection circuit detects a plurality of return voltages of the return lines and generates a plurality of detection signals accordingly so as to indicate that a switch of each of the keys is at an on state or at an off state. The detection circuit includes a plurality of P-type transistors. A first terminal of each P-type transistor is coupled to a ground terminal, a control terminal of each P-type transistor is directly coupled to a corresponding one of the return lines, and a second terminal of each P-type transistor generates and outputs one of the detection signals.

Claim (Index 4):
The keyboard apparatus as recited in  claim 1 , wherein:\n when the return voltage of the corresponding one of the plurality of return lines is greater than or equal to a reference voltage, the switch of the key coupled between the corresponding one of the plurality of return lines and an activated scan line of the plurality of scan lines is at an off state, wherein the reference voltage is associated with a threshold voltage of the P-type transistor.
