Abstract: An optoelectrical assembly includes a voltage conversion circuit, an optoelectrical semiconductor device, an optoelectrical detection circuit, and a controller. The voltage conversion circuit provides a bias voltage to the optoelectrical semiconductor device, and adjusts, by changing the bias voltage, an output optical power. A differential resistance value (Rdiff) of the optoelectrical semiconductor device within a range of a target optical power satisfies 0.1 ohm (Ω)≤Rdiff≤50Ω, and the differential resistance value is a ratio of a voltage variation to a current variation corresponding to the voltage variation. The optoelectrical detection circuit detects the output optical power, and outputs a detection signal to the controller. The controller determines a control signal based on the detection signal, and outputs the control signal to the voltage conversion circuit, where the control signal is used to adjust the bias voltage.

Abstract: A distributed display method provides different parts of an application interface that are collaboratively displayed on a plurality of terminals, so that manners for collaborative display between the plurality of terminals are more flexible and richer. A first terminal displays a first interface including a first part and a second part. When the first terminal detects that a preset condition is met, the first terminal displays a second interface, where the second interface includes the first part and does not include the second part; and the first terminal notifies a second terminal to display a third interface, where the third interface includes the second part and does not include the first part.
