摘要： A display device includes a display capacitor, a data switching device, and a reset switching device. The data switching device may transmit a data voltage to the display capacitor in response to an activating gate signal that is applied to the data switching device for a activating gate signal duration. The reset switching device may transmit a storage voltage to the display capacitor in response to an activating reset signal that is applied to the first reset switching device for an activating reset signal duration. The storage voltage is configured for resetting a pixel associated with the first display capacitor. The activating reset signal duration is longer than the activating gate signal duration.

摘要： Disclosed herein is a pulsation damper using a single-sided corrugated disk spring. In the pulsation damper using a single-sided corrugated disk spring, a section-expanded fuel rail inlet expanded to be equal to a section of a high-pressure fuel pipe is formed in an inlet-expanded fuel rail and a single-sided corrugated spring pulsation damper is attached to the inlet-expanded fuel rail, so that high-pressure fuel pump pulsating waves generated in the inlet-expanded fuel rail by a high-pressure fuel pump and injector pulsating waves generated in a fuel injector are mixed with each other and mixed pulsating waves generated in the inlet-expanded fuel rail are reduced.

摘要： A display device includes a first gate driver that applies a gate-on voltage to gate lines of a first gate line group in each period of n first scan periods for a first frame, n being a natural number. A second gate driver applies a gate-on voltage to gate lines of a second gate line group in each period of n second scan periods for a first frame. A data driver applies a data voltage to a plurality of data lines. A signal controller transmits a control signal to the first and second gate drivers and the data driver, wherein an interval between start points of the n first scan periods is gradually decreased according to time, and an interval between start points of the n second scan periods is gradually increased according to time.
