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 1):
A keyboard device, comprising:\n M column signal lines C(1)\u02dcC(M); N row signal lines R(1)\u02dcR(N), wherein M and N are positive integers, wherein M*N intersections are formed by the N row signal lines R(1)\u02dcR(N) extending across the M column signal lines C(1)\u02dcC(M); N transition circuits TC(1)\u02dcTC(N), electrically coupled to the N row signal lines R(1)\u02dcR(N) respectively; a control module comprising N input ports and M output ports, wherein the N input ports are electrically coupled to the N transition circuits TC(1)\u02dcTC(N) respectively, and the M output ports are electrically coupled to the M column signal lines C(1)\u02dcC(M) respectively; and M*N key units KU(1,1)\u02dcKU(M,N) disposed neighboring to the M*N intersections, respectively, wherein a key unit KU(i,j) of the M*N key units KU(1,1)\u02dcKU(M,N) comprises a switch sw(i,j), wherein a first end of the switch sw(i,j) is connected with a column signal line C(i), a second end of the switch sw(i,j) is connected with a row signal line R(j), i is a positive integer smaller than or equal to M and represents which column signal line the switch sw(i,j) is connected, and j is a positive integer smaller than or equal to N and represents which row signal line the switch sw(i,j) is connected, wherein when the key unit KU(i,j) is depressed, the column signal line C(i) and the row signal line R(j) are electrically coupled to each other through the switch sw(i,j); wherein the control module performs a scanning process to sequentially scan the M column signal lines C(1)\u02dcC(M) in M scan cycles scan(1)\u02dcscan(M), and the scanning process comprises steps of: (a) setting an initial value of k, wherein the initial value of k is a positive integer smaller than or equal to M; (b) entering a scan cycle scan(k); (b1) providing a scan voltage to the k-th column signal line C(k) and providing an un-scan voltage to the column signal lines C(1)\u02dcC(k\u22121) and C(k+1)\u02dcC(M) through the M output ports, wherein a voltage level of the un-scan voltage is lower than a voltage level of the scan voltage; (b2) determining whether N key units KU(k,1)\u02dcKU(k,N) connected with the k-th column signal line C(k) are conducted through the N transition circuits TC(1)\u02dcTC(N),\n wherein when a 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, the 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), and a transition circuit TC(x) being coupled to the x-th row signal line R(x) outputs a first voltage level, wherein x is a positive integer smaller than or equal to N, \n wherein when a key unit KU(m,x) connected with the m-th column signal line C(m) and the x-th row signal line R(x) is depressed, the un-scan voltage is transmitted from the m-th column signal line C(m) to the x-th row signal line R(x) through a switch sw(m,x) of the key unit KU(m,x) so that the transition circuit TC(x) being coupled to the x-th row signal line R(x) is incapable of outputting the first voltage level, wherein m is a positive integer smaller than or equal to M, and m is not equal to k; \n wherein if the transition circuit TC(x) outputs the first voltage level, the control module determines that the key unit KU(k,x) is depressed,\n wherein if the transition circuit TC(x) stops outputting the first voltage level, the control module determines that the key unit KU(k,x) is not depressed; and \n (c) repeatedly performing the step (b1) and the step (b2) according to an updated k corresponding to the un-scanned column signal lines until all of the column signal lines C(1)\u02dcC(M) have been scanned once.
