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.
