Gate drivers of the GOA circuit, the array substrate, and the display apparatus occupy small areas, and the driving method can implement single point polarity reversal.
If the time intervals do not correspond to the expected time intervals or if the predetermined events do not occur within the predetermined time windows or plausibility windows, this denotes a polarity reversal.
Switching transitions of the first (14) and second (16) synchronous rectifiers are initiated by a polarity reversal of the voltage of the secondary transformer winding.
Such information may be supplemented by the presence or absence of a line polarity reversal before the activation signal is sent and by modulated signals, such as FSK signalling.
The duplex fiber optic connector assemblies and fiber optic cable assemblies (110) allow rotation of individual fiber optic connectors (10A, 10B) within the housing assembly (30) for polarity reversal.
A polarity reversing DC power inserter circuit (204) for other signal control apparatus used in a cable or community antenna television (CATV) signal distribution system.
The light emitting device comprises one and the other light emitting diode devices (2, 3) connected in parallel to have reverse polarities, and a constant current power supply unit (4) capable of polarity inversion.
The present invention possesses the good capability of ultra low speed load, good capability of charging to battery , large output power and high power cross ratio.
In addition, the plasma is driven at this current level almost continuously (with reversing polarity), which does not allow the plasma time to cool down.
A portable hand-carrying auto-polarity battery booster apparatus includes a power storage device which is capable of providing power to an electrical system such as a battery.
A switching sequence is provided whereby all colour fields are addressed according to a sequence of the type red, green, blue, green, red, green, blue, etc., with polarity inversion.
This arrangement provides polarity inversion voltage waveforms when switching voltages are applied to the lens elements, and with maximised RMS voltage.
At the signal control apparatus, the polarity reversing DC is converted into DC by a power utilization circuit, and then utilized to power the signal control apparatus.
