Abstract:
1. An electronic device, comprising a power supply, a display screen, and a housing, wherein the housing is configured to have multiple independent color-variable units, and each color-variable unit, which is connected to the power supply, is made of electrochromic materials with capacity of memory respectively; and the electronic device further comprises: a user operation interface, configured to receive an instruction inputted by a user for selecting a housing pattern; a master controller, which is connected to the user operation interface, configured to convert the selected housing pattern into a first control signaling, and then to output the first control signaling; and a control circuit, which is connected to the master controller, configured to receive the first control signaling, and to convert the first control signaling into different voltage signals to control the each color-variable unit of the housing to change the color; wherein the control circuit comprises: a circuit for interface and decoding, configured to analyze the first control signaling from the master controller and to obtain an address and corresponding color information of the each color-variable unit; a chip selection decoder, configured to output the color information of the each color-variable unit according to the address of the each color-variable unit; and a decoder, which is connected to the each color-variable unit correspondingly, configured to decode the color information from the chip selection decoder and to convert the color information into the voltage signals, then to control an input voltage of the connected corresponding color-variable unit according to the voltage signals in order that the connected corresponding color-variable unit displays a color corresponding to the color information.
