A display device is provided, which includes an image buffer, a display module, and a display controller. The display controller is used for receiving an image signal from a host, and storing the image signal in the image buffer. In response to the display controller receiving a trigger signal, the display controller controls the display device to enter an image-rewinding mode. The display controller obtains a retrospective image that corresponds to a retrospective time point according to a user command, and plays the retrospective image on the display module.

Display device and method of image rewinding thereof

A power switch device includes a switch, a control unit, and a communication interface. The switch includes a power input terminal, which is configured to receive an external power; and a power output terminal, which is configured to output the external power. The switch normally remains open. The control unit is turned on when receiving the external power via the power input terminal, and transmits a start request via the communication interface. The control unit determines whether the communication interface receives a busy message within a delay time period. If the busy message is not received within the delay time period, the control unit controls the switch to be closed, and sets a start process time period. Within the start process time period, if the communication interface receives another start request, the control unit generates another busy message to respond to the another start request via the communication interface.

Power switch device

An electronic system and a method for recognizing status of a power-supply device are provided. The electronic system includes a power-supply device and an electronic device. The power-supply device generates a working power and stores an accumulated operation time length and a suggested operation time length of the power-supply device. The electronic device is coupled to the power-supply device and receives the working power to perform a booting operation. The electronic device reads the accumulated operation time length and the suggested operation time length from the power-supply device and compares the accumulated operation time length and the suggested operation time length. If the accumulated operation time length is greater than or equal to the suggested operation time length, the electronic device generates a warning message to indicate that the power-supply device has reached a life time.
