Electronic device

The invention relates to an electronic device. An apparatus is configured to operate in a first mode of operation during which the apparatus is configured to receive a first supply voltage in a contactless manner. The apparatus includes a light emitting element and a first circuit. The first circuit is configured to receive a second supply voltage generated from the first supply voltage. A first current independent of the second voltage is generated from the first supply voltage, and the first current is applied to the selectively turned-on light emitting element. 本公开涉及电子设备。一种设备被配置为在第一操作模式下操作，在第一操作模式期间，所述设备被配置为按照非接触方式接收第一供给电压。所述设备包括发光元件和第一电路。第一电路被配置为接收从第一供给电压产生的第二供给电压。从第一供给电压产生独立于第二电压的第一电流，并且第一电流被施加于选择性地接通的发光元件。
