Abstract

A keyboard with wire aging self-adaption, a self-adaption method for keyboard, an electronic computing device readable medium with a stored program, and an electronic computing device program product are provided. In the keyboard, a processor feeds a scanning signal to each scanning line in turn during a scanning round. In response to the conduction state of one of switching elements, the processor detects a return signal on the corresponding return line and selects one or more scanning lines as a testing line. During a first duration in which the testing line maintains the scanning signal, according to the time difference between the starting points of the first duration and the return signal and the response time parameter corresponding to the testing line that is stored in the memory, the processor determines whether to update the response time parameter corresponding to the testing line that is stored in the memory.

Dependent claims

A keyboard with wire aging self-adaption, comprising:

a scanning circuit comprising a plurality of scanning lines, a plurality of return lines, and a plurality of switching elements, wherein the switching elements are respectively coupled to intersections of the scanning lines and the return lines;
a memory storing a plurality of response time parameters respectively corresponding to the scanning lines;
and
a processor coupled to the scanning circuit and the memory, wherein in a scanning round, the processor feeds a scanning signal to each of the scanning lines in turn, the processor selects at least one of the scanning lines as a testing line, and in response to a conduction state of one of the switching elements coupled to the testing line, the processor detects a return signal on the return line corresponding to said switching element;
in a first duration in which the testing line maintains the scanning signal, the processor detects a starting point of the first duration to a starting point of the return signal corresponding to the first duration to obtain a time difference, and according to the time difference and the response time parameter corresponding to the testing line that is stored in the memory, the processor determines whether or not to update the response time parameter corresponding to the testing line that is stored in the memory.
