Membrane keyboards utilize a series of membranes to detect key presses, but they are often plagued by key rollover issues. When a key is pressed, it creates a depression in the membrane, which the keyboard controller recognizes as a key press. However, if another key is pressed while the first key is still depressed, both key presses should ideally be registered by the controller. This phenomenon is known as key rollover.
Key rollover presents a significant concern for membrane keyboards due to their tendency to have a limited capacity for simultaneous key presses. This limitation stems from the keyboard controller’s ability to detect only a set number of depressions in the membrane at once. If the number of key presses exceeds this limit, the controller may fail to detect the additional key presses. This can lead to functionality issues in games or applications reliant on keyboard input, potentially impeding proper operation if key presses go undetected.
