Anti-ghosting keyboard

An anti-ghosting keyboard, comprising:

• a sensing unit including a plurality of sensing modules, each of said sensing modules including N number of switches and N number of sensing resistors, said N number of sensing resistors corresponding respectively to said N number of switches, where N is a positive integer greater than one,
• wherein for each of said sensing modules, resistance values respectively of said N number of sensing resistors form an ascending sequence, and any one of the resistance values in the ascending sequence, except for a first one of the resistance values, is greater than a sum of all of those of the resistance values before said any one of the resistance values in the ascending sequence, and
• wherein for each of said sensing modules, a conduction status of said N number of switches causes said sensing module to produce an equivalent resistance value, which is one of 2N number of possible equivalent resistance values that respectively correspond to 2N number of possible conduction statuses of said N number of switches;
• a detection unit including at least one divider resistor that is connected in series with at least one of said sensing modules, and at least one detection module that is electrically connected to at least one point of connection between said sensing unit and said at least one divider resistor, said at least one detection module being configured to obtain at least one divided voltage value across said at least one divider resistor and to generate, based on the at least one divided voltage value, at least one potential level value that corresponds to a proportion between the equivalent resistance value of said at least one of said sensing modules and a resistance value of said at least one divider resistor;
• and
• a processing unit electrically connected to said at least one detection module for receiving the at least one potential level value therefrom, and configured to generate at least one key-press signal that corresponds to said at least one of said sensing modules based on the at least one potential level value thus received.
