  • Patent number: 8330698
    Abstract: A signal generating circuit for a liquid crystal display (LCD) includes circuitry adapted to receive a gate clock signal and an output enable signal. The gate clock signal is a combination of a gate-on signal and a gate-off signal and the output enable signal is operable to adjust the width of the gate-on signal. The signal generating circuit adjusts the output enable signal such that a falling edge of the output enable signal overlaps a rising edge of the gate clock signal and thereby delays the gate clock signal for a selected amount of time.

  • Patent number: 8330916
    Abstract: A liquid crystal display (LCD) includes thin film transistors (TFTs) each having spaced apart source/drain electrodes and an oxide-type semiconductive film disposed over and between the source/drain electrodes to define an active layer. Each of the source/drain electrodes includes a portion of a subdivided transparent conductive layer where one subdivision of the transparent conductive layer continues from within its one of the source/drain electrodes to define an optically exposed pixel-electrode that is reliably connected integrally to the one source/drain electrode. Mass production costs can be reduced and production reliability increased because a fewer number of photolithographic masks can be used to form the TFTs.

  • Patent number: 8326036
    Abstract: A method of decomposing a set of scans of different views of overlapping objects into constituent objects is presented. The method involves an initialization process whereby keypoints in two views are determined and matched, disparity between keypoint pairs are computed, and the keypoints are grouped into clusters based on their disparities. Following the initialization process is an iterative optimization process whereby a cost function is calculated and minimized assuming a fixed composition matrix and re-solved assuming a fixed attenuation coefficient. Then, the composition matrix and the attenuation coefficient are updated simultaneously, and the solving, the re-solving, and the updating steps are repeated until there is no significant improvement in the result.

    Abstract: Disclosed is a gate printed circuit board, a connector-free liquid crystal display (LCD) panel assembly, a driving-signal timing module included in the liquid crystal display (LCD) panel assembly, and a method of driving the liquid crystal display (LCD) panel assembly. According to the present invention, since a separate connector and a gate printed circuit board of a conventional LCD panel is not required for applying a gate-driving signal generated from an external information processing device, a thickness and the number of parts of the LCD device is reduced. Further, when the gate-driving signal is transmitted through the TFT substrate, the voltage Voff for maintaining a thin-film transistor (TFT) in a turned-off state is modified so that users may not recognize the imbalance in brightness.
