摘要： A light source supplies optical signal to an optical switch and a detector detects light receiving level. A control unit changes a deflection control amount for changing an angle of a tilt mirror, and outputs the deflection control amount to a driving unit. When an input and an output ports are same, optical offset of the tilt mirror is calculated based on optimal angle at which the light detector detects an optimal point of the light receiving level. Whenever the input and the output port are different, a structure parameter of the tilt mirror is calculated based on the optical offset and the optimal angle. The optical offset and the structure parameter are stored in a memory as a test result.

摘要： The light emission panel display device according to the present invention has a scan drive circuit (30) driving a selected scan line to a selected voltage and unselected scan lines to a non-selected voltage higher than the selected voltage in each scanning period and (3) a data drive circuit (20) supplying light-emitting drive current to the data lines respectively in the periods of light emission corresponding to display gradation. The data drive circuit (20) starts supply of the light-emitting drive current to the data lines respectively at the emission-initiation timing corresponding to the emission period in the scanning period, and terminates supply of the light-emitting drive current to the multiple data lines at the same emission-termination timing. In addition, the scan drive circuit (30) maintains the selected scan line to an emission-termination voltage higher than the selected voltage and terminates light emission of the light-emitting element connected to the selected scan line at the emission-terminating timing. It is thus possible to prevent continuous light emission of the light-emitting element emitting light by electrical charging and discharging at the emission-termination timing during light emission.

摘要： In controlling an optical switch that includes an incoming light deflection section to deflect incoming light from a predetermined input port in an arbitrary direction, and an outgoing light deflection section to deflect outgoing light from the incoming light deflection section in an arbitrary direction and couple the outgoing light to a predetermined output port, a monitoring section monitors optical coupling efficiency of the outgoing light into the output port and controller controls deflection characteristics of the deflection sections so that the monitored optical coupling efficiency is maximized. Therefore, even when optimal controlled variables for the optical switch are displaced due to temperature drift and/or drift over time, the time taken to find the optimal controlled variables can be significantly reduced and rapid switching of optical paths can be achieved.
