Abstract
An electronic device includes a transparent substrate, an antenna, a first chip, and a second chip. The antenna is disposed above the transparent substrate. The first chip includes a sensor. The sensor is configured to detect whether the antenna has received a wireless signal or not. The second chip is coupled to the first chip, and operates in a power-saving mode. When the antenna receives the wireless signal, the first chip wakes up the second chip such that the second chip switches from the power-saving mode to a work mode, and the first chip transmits the wireless signal to the second chip.
