  • Publication number: 20060284815
    Abstract: An apparatus and method for driving a liquid crystal display device are disclosed. The apparatus includes a liquid crystal panel with pixels defined by data and gate lines. A gate driver provides different gate pulses to the odd-column pixels than to the even-column pixels. The gate pulses have different voltages and/or widths. Data drivers provide data voltages having a positive or negative polarity to the data lines. A timing controller controls the gate and data drivers and supplies gate clock pulses that have different voltages and/or widths to the gate driver.

  • Publication number: 20060061535
    Abstract: Disclosed herein are a liquid crystal display device, in which a bi-directional internal gate drive circuit is used to cut the number of data lines in half, and a method of driving such liquid crystal display devices. The liquid crystal device includes a pixel array having a plurality of pixels on a lower substrate. The pixels are configured such that two pixels horizontally adjacent to each other are paired to share the same data line. First and second gate drive circuits are housed in the left and right sides of the lower substrate so as to be independently operated in the left and right side of the pixel array. The first gate drive circuit is formed of first to nth odd shift registers, and the second gate drive circuit is formed of first to nth even shift registers.

  • Publication number: 20060044247
    Abstract: A built-in gate driver having an improved reliability and a display device having the same are provided. A transistor controlled by an output signal of a next stage is further provided and thus a node (Q) is rapidly discharged. Accordingly, the multi-output signals due to the reduced discharge of the node (Q) caused by the degradation of the transistor controlled by a node QB can be prevented. By including only one transistor for controlling the charge of the start pulse signal on the node (Q), it is possible to prevent a malfunction from occurring when the transistor connected to the clock is degraded by the periodic clock of a high state. Also, an image quality and the reliability of the gate driver can be improved.

  • Publication number: 20050220262
    Abstract: An output buffer in each stage of a shift register applies a first clock signal to an output line under control of a first node and a second driving voltage to the output line under control of second and third nodes. A first node controller controls the first node using a start pulse and an output signal of the next stage. A second node controller selectively applies a voltage at a fourth node and the second driving voltage to the second node under control of the first and second clock signals. A third node controller applies the voltage at the fourth node and the second driving voltage to the third node opposite to the second node. A fourth node controller controls the fourth node such that the fourth node has a voltage opposite to the first node using a voltage at the first node and the first driving voltage.
