  • Patent number: 8760383
    Abstract: A backlight module includes a light-emitting unit, and a controller to receive a first control signal and generate a second control signal to control the light-emitting unit. The controller controls a frequency of the second control signal according to a duty cycle of the first control signal.

  • Patent number: 8638049
    Abstract: A driving device, a light emitting diode (LED) driving device and a method thereof are provided. The driving device includes a driving unit and a plurality of selection units. The driving unit produces a driving signal to drive a light emitting diode. The selection units are coupled to the driving unit and respectively correspond to a current value. The driving unit selects one of the selection units according a first pulse width modulation (PWM) signal. The current value corresponding to the selected selection unit is taken as the current value of the driving signal. The driving unit generates a duty cycle of a second PWM signal according to the duty cycle of the first PWM signal to serve as a duty cycle of the driving signal. In this way, power consumption of the LED is reduced.

  • Patent number: 6897908
    Abstract: A liquid crystal display panel includes an upper substrate, a lower substrate, and a plurality of pixels located between the upper substrate and the lower substrate. Each of the pixels has at least a compensating capacitor for providing an approximately identical feed-through voltage for each of the pixels, thus reducing a flicker effect of the liquid crystal display device.

  • Patent number: 6809719
    Abstract: A thin film transistor liquid crystal display (TFT LCD) has row pairs of pixels. Each row pair of pixels includes first row pixels arrayed in a first row, and second row pixels arrayed in a second row, together forming columns of pixels. First and second data drivers are provided for each column of pixels. Scan line drivers are provided for each row pair of pixels so that every pixel in a row pair of pixels is connected to the same scan line driver. Every first row pixel in a column of pixels is connected to the same first data driver, and every second row pixel in a column of pixels is connected to the same second data driver.
