Abstract:
A keyboard device includes M driving circuits DC(1)˜DC(M), N transition circuits TC(1)˜TC(N), a control module, M column signal lines C(1)˜C(M), N row signal lines R(1)˜R(N) and M*N key units KU(1,1)˜KU(M,N). The control module performs a scanning process to sequentially scan the M column signal lines C(1)˜C(M) in M scan cycles scan(1)˜scan(M). If the key unit KU(k,x) connected with the k-th column signal line C(k) and the x-th row signal line R(x) is depressed, a scan voltage is transmitted from the k-th column signal line C(k) to the x-th row signal line R(x) through a switch sw(k,x) of the key unit KU(k,x). The transition circuit TC(x) connected with the x-th row signal line R(x) is turned on according to the scan voltage. Consequently, an output voltage Rout(x) from the transition circuit TC(x) has a first voltage level.

Claim (Index 7):
The keyboard device as claimed in  claim 5 , wherein the control module comprises:\n a controller comprising a controller output port and Q column select ports, wherein Q is a positive integer smaller than M; and a demultiplexer comprising a demultiplexer input port, Q column set ports and M driving output ports, wherein the demultiplexer input port is connected with the controller output port, the Q column set ports are electrically coupled to the Q column select ports, and the M driving output ports are electrically coupled to the M driving circuits.
