Abstract: A method for determining whether or not a display panel is a duplicate is provided. The method includes: generating, by a code generator in an electronic module, a code, the electronic module including a plurality of electronic components; transmitting, by the code generator, the code to each of a first sequence generator in the electronic module and a second sequence generator in a display panel, the display panel being configured to be mounted to the electronic module; generating, by the first sequence generator, a first response value, and transmitting the first response value to a certification component in the electronic module; generating, by the second sequence generator, a second response value, and transmitting the second response value to the certification component; and comparing, by the certification component, the received first response value and the received second response value.

Abstract: An electronic device, including a touch recognition unit; a display unit receiving a signal from the touch recognition unit; a fingerprint recognition unit receiving a signal from the display unit. A processor is configured to transmit and receive a signal to/from the touch recognition unit, the display unit, and the fingerprint recognition unit. The processor may remain in an inactive state while the touch recognition unit, display unit, and fingerprint recognition unit are activated. The processor is activated when a preset user's fingerprint input is provided. A method operates the electronic device.
