Abstract: A circuit for preventing power imbalance of a resonance-type power converter is proposed. The circuit may include a rectifier converting input alternating current (AC) into direct current (DC) and frequency-controlled first and second resonant converter modules configured to receive an output voltage of the rectifier divided into two stages. The circuit may further include a controller outputting a first frequency command for controlling a frequency of a pulse width modulation (PWM) signal supplied to a switching element of a first switching unit of the first resonant converter module. The circuit may further include a frequency compensator compensating for the first frequency command and then outputting a second frequency command for controlling a frequency of a PWM signal supplied to a switching element of a second switching unit of the second resonant converter module, so as to eliminate power imbalance between the first and second resonant converter modules.

Abstract: A pixel includes: a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is applied, and a third node electrically connected to the light emitting element; a first emission control transistor having an on-off timing controlled by a first emission control signal; and a second emission control transistor having an on-off timing controlled by a second emission control signal. A time interval exists between a time at which the first emission control signal having a turn-on level is input such that a voltage of the second node is dropped from a bias voltage having a voltage level higher than a voltage level of the first power voltage and a time at which the second emission control signal having a turn-on level is input.
