In a power supply apparatus (100), a booster circuit (10) supplies a drive voltage (Vout) to a plurality of light emitting diodes (300R-300B).
A display driver (4) supplies a drive voltage (VD) between the first data electrode (DE1) and the second data electrode (DE2).
Furthermore, the drive voltage applying circuit increases the positive voltage in the electron emission period (Th) stepwise, and the electrons accumulated in the emitter part are emitted separately in a plurality of times.
Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device.
A light-emitting element having a low driving voltage is provided.
A driving voltage (VDD) is applied to the drain of the second FET (102).
Opposite driver voltage waveform is output from between the odd and even columns of the neighboring columns.
The organic electronic device according to the present invention shows excellent characteristics in efficiency, driving voltage, and life time.
Provided is an excellent organic light emitting element having high emission efficiency and a low drive volatage.
Provided is an organic light emitting device having high emission efficiency and a low driving voltage.
The first state (φ1) and the second state (φ2) are switched to each other at the same frequency as that of a driving voltage (VDRV).
Provided is a high-speed response and low voltage driven electromechanical element having a mechanism for adjusting a spring constant of a movable electrode.
