摘要： A display panel driving apparatus and a method of driving the same are provided, and, in particular, a gate driver and a method of driving the gate driver. The gate driver includes a decoder that decodes gate line selection data and that generates a gate line selection signal. A gate driving circuit generates a gate driving signal in a pre-charging phase and a driving phase in response to the gate line selection signal and a pre-charging control signal that controls an off-state of non-selected gate lines. In a time period of the driving phase in which a gate line is not selected, a node that has been in a floating state is held to a target voltage level in response to a hold control signal. The hold control signal is generated based upon a timing relationship between the gate line selection signal and the pre-charging control signal.

摘要： A gray scale voltage decoder includes a first decoding unit and a second decoding unit, in which the first decoding unit includes row blocks. Each of the row blocks receives one of a number of gray scale voltages and determines whether to output the received gray scale voltage in response to first bits of digital image data provided through data input lines formed along a column direction. Row blocks outputting the received gray scale voltage according to the same values of the first bits are arranged adjacently. The first decoding unit selects part of the gray scale voltages to output the selected gray scale voltages. The second decoding unit selects one of the gray scale voltages selected by the first decoding unit in response to second bits of the digital image data and outputs the selected gray scale voltage.
