Abstract
The invention discloses an electronic device power-on password input method and an electronic device. The electronic device comprises a lattice screen, a keyboard, a key driver and a controller. The controller is connected with the lattice screen and the key driver, and the keyboard is connected with the key driver. The keyboard comprises three input keys, namely, the leftward-shifting key, the rightward-shifting key and the enter key. The input method includes the steps that the controller receives a rightward-shifting signal, a leftward-shifting signal and an enter signal from the three input keys through the key driver, and controls a cursor of a virtual keyboard on the lattice screen to conduct rightward shifting, leftward shifting and entering to form characters which form a power-on password. By means of the input method and the electronic device, the number of entity keys on hardware is lowered, the keyboard space is effectively reduced, and the size of a designed electronic product is made to be smaller.
