An anti-counterfeiting electronic device includes a function component assigned with an identification code ID and a processor. The processor generates a random code Kand transmits the random code Kto the function component; the function component encrypts the random code Kand the identification code ID to generate a key ID. The processor further obtains the key IDfrom the function component and decrypts the key IDto generate an identification code ID, and determines whether the identification code IDis the same as the ID and executes the system login command if the identification code IDis the same as the identification code ID. An anti-counterfeiting method is also provided.

Anti-counterfeiting electronic device and method thereof

An electronic reader system includes an electronic book and a stylus. The electronic book includes a battery and a cover. The stylus includes a pen body for writing on the electronic book to input data or commands into the electronic book, and an illumination member detachably attached to the pen body. The illumination member can be detached from the pen body and attached onto the electronic book, receiving electrical power from the book as it does so, to illuminate the electronic book.

Electronic reading system

An electronic device capable of controlling light-emitting diode (LED) bright is provided. The electronic device includes a signal producing unit for producing an operation signal; a Micro Control Unit (MCU) configured for outputting a normal brightness control signal according to the operation signal, and outputting a ultra brightness control signal according to the operation signal when an actual idle time of the electronic device reaches or exceeds a predetermined idle time; a pulse current control unit for controlling an output current according to the normal brightness control and the ultra brightness control signal; and a LED illuminator array for emitting light based on the output current. The MCU terminates the output of the ultra brightness control signal when an actual time of outputting the ultra brightness control signals reaches a predetermined time, and then the LED illuminator array resumes its normally bright. A control method is also provided.
