Abstract: A method of providing display signal, performed by a first processing device, and the method includes: triggered by a first detection signal to read first identification data of a display, obtaining second identification data according to a reading condition, outputting a second detection signal to a second processing device to obtain an identification data request signal from the second processing device, and outputting the second identification data to the second processing device according to the identification data request signal to instruct the second processing device to output a display signal to the display according to a resolution indicated by the second identification data. The present disclosure further provides a resolution setting device and a display system.

Abstract: An electronic device and a power supply method thereof are provided. The electronic device includes a control circuit, a detachable power supply device, and an auxiliary power supply device. The control circuit is coupled to a power supply terminal coupled to a system load. When the detachable power supply device is assembled to the electronic device, the detachable power supply device is coupled to the control circuit and supplies power to the system load. The auxiliary power supply device is coupled to the control circuit. When the electronic device is not turned on and the detachable power supply is removed from the electronic device, the electronic device is not turned on by the auxiliary power supply device. When the electronic device is turned on and the detachable power supply is removed from the electronic device, power is continuously supplied to the system load by the auxiliary power supply device.

Abstract: A method for automatic display of a spread in ebooks is revealed. The method includes several steps. First scan at least one paper book by a scanner to get at least one original page file with at least two original pages. Then execute a transcription suite in a computing device for transcribing the original page file into an e-book and write at least one spread event into at least one electronic page of the e-book by an input device. Next use a reader to read the e-book. The reader triggers the spread event while reading the electronic page written with the spread event. Thus the reader automatically retrieves and displays at least two electronic pages on a monitor of the reader simultaneously. Therefore the spread covering at least two electronic pages is automatically displayed on a monitor of the reader.
