Abstract

This invention discloses a method for recognizing the status of a button with a display in a dark environment. The recognition method includes providing a first button and a second button. The first button has a first display character, which includes a pair of concave arrows and a button name located inside the pair of concave arrows. The first button is configured such that the first display character is illuminated in a pressed state and extinguished in a released state. The second button has a second display character, which includes a pair of convex arrows and a button name located inside the pair of convex arrows. The first display character and the second display character have the same button name. The second button is configured such that the second display character is illuminated in a released state and extinguished in a pressed state. The beneficial effect of this invention is that it solves the problem of difficulty in recognizing the pressed / released state of a button by its height in a dark environment, avoiding operator misjudgment and misoperation.
