  • Patent number: 11118519
    Abstract: A method of controlling a hybrid electric vehicle is provided. The method includes determining whether a condition for turning off an engine is satisfied and determining engine clutch disengaging time and residual purge gas consuming time from engine driving status information when the condition is satisfied. Engine clutch-engaged charging control time is determined from the engine clutch disengaging time and the residual purge gas consuming time. The method includes closing a purge control solenoid valve and starting to perform engine clutch-engaged charging control. The engine clutch-engaged charging control is maintained for the determined engine clutch-engaged charging control time and then engine clutch disengaging control is performed for the determined engine clutch disengaging time. The engine is stopped after the engine clutch disengaging control is performed.

  • Patent number: 10401677
    Abstract: The present disclosure relates to a display device including a display panel on which an image is displayed, a polarizer disposed on the display panel, a lower fluorescent filter disposed on the polarizer, and an upper fluorescent filter disposed on the lower fluorescent filter. The present disclosure may improve visibility when an image is displayed on the display device and light of a laser pointer in a visible light region is emitted thereto by absorbing the light using the upper and lower fluorescent filters, converting the light into light in a long wavelength band, which is a higher wavelength band than that of the absorbed light, and emitting the light in the long wavelength band.

  • Patent number: 8960935
    Abstract: Disclosed is a printed circuit board, on which a holder for fixing a lamp is mounted, is disposed on an upper surface of a bottom cover, and an inverter supplying a driving voltage to the lamp is disposed on a lower surface of the bottom cover. The printed circuit board is electrically connected to the holder as a conductive pattern is embedded in the printed circuit board. The connector is directly mounted on the inverter, or it is connected to the inverter via a wire. In this case, the connector is also connected to the printed circuit board. Therefore, the connector of the inverter and the connector of the printed circuit board are electrically connected.

  • Patent number: 8416182
    Abstract: An apparatus and method for driving a liquid crystal display (LCD) device is disclosed. The apparatus for driving a liquid crystal display (LCD) device includes a liquid crystal display (LCD) panel for receiving a video signal and a clock signal, and displaying them, a backlight for emitting light on the LCD panel, a timing controller for controlling the LCD panel and the backlight, a signal generator which has the same frequency as that of a horizontal synchronous signal by modulating the clock signal, and generates a signal synchronized with the horizontal synchronous signal, and an inverter which receives a signal from the signal generator, allows a driving frequency of the light source to be the same as that of the horizontal synchronous signal, and allows the received signal to be synchronized with the horizontal synchronous signal.
