An electronic apparatus, a method for controlling the electronic apparatus, and a storage medium. The electronic apparatus includes a display screen, an electrochromic component arranged on the display screen, a functional component covered by the electrochromic portion, and a control circuit electrically connected to the electrochromic component and configured to control the electrochromic component. When the functional component is in an active state, the control circuit controls to increase a light transmittance of the electrochromic component, such that the functional component of the electronic apparatus is able to acquire an optical signal transmitting through the electrochromic component; when the functional component is in an idle state, the control circuit controls to reduce the light transmittance of the electrochromic component, such that the functional component of the electronic apparatus is able to be hidden.

Disclosed herein are electrochromic devices. The electrochromic devices can comprise: an electrochromic electrode comprising an electrochromic layer and a first conducting layer; an electrolyte comprising an ion source; and a counter electrode comprising a second conducting layer; wherein the electrochromic electrode is in electrical contact with the counter electrode; and wherein the electrochromic electrode and the counter electrode are in electrochemical contact with the electrolyte. In some examples, the electrochromic devices can have s charge capacity of 10 mC/cm.sup.2 or more after being photocharged for 20 minutes or less at an applied electrical bias of 2 V or less.
