  • Patent number: 9554434
    Abstract: A light-emitting diode driver includes a power switch, a logic unit and a pulse adjustment signal generator. The power switch is used to control a charging level of a light-emitting diode voltage terminal, and controlled to be turned on or off by a pulse-width modulation signal. The logic unit is coupled to a control terminal of the power switch, and used to generate a frequency control signal. The pulse adjustment signal generator is coupled to the logic unit, and used to generate an operational wave according to the frequency control signal and update the pulse-width modulation signal according to the operational wave. When the duty cycle of the pulse-width modulation signal is smaller than a pulse-width modulation threshold, the operational wave has a first frequency. When the duty cycle of the pulse-width modulation signal is larger than the pulse-width modulation threshold, the operational wave has a second frequency higher than the first frequency.

  • Patent number: 9082364
    Abstract: A source driving system includes first and second source driving integrated circuits. The first driving integrated circuit includes a first source driver for receiving first display data and driving pixels in a first block of a display panel according to the first display data. The second source driving integrated circuit includes a second source driver electrically connected to the first source driver for receiving second display data and driving pixels in a second block of the display panel according to the second display data. The first and the second source drivers generate first and second display parameters according to the first and the second display data respectively. The second display parameter is transmitted from the second source driver to the first source driver. The first source driver generates a third display parameter according to the first and second parameters and transmits the third display parameter to the second source driver.

  • Publication number: 20140230770
    Abstract: A transient plasma electrode apparatus may include an elongated electrode having a first and a second end. The first end may connect to a source of high voltage pulses. An insulation jacket may surround a portion of the electrode. An electric-field enhancing protrusion may be at the second end of the elongated electrode. The protrusion may cause an electric field when a high voltage is applied between the elongated electrode and a metallic wall of a combustion chamber in which the electrode is placed. The electric field may be greater at the second end as compared to along the length of the electrode.
