  • Patent number: 8816950
    Abstract: In a timing controller and a display apparatus, the timing controller generates an internal enable signal based on an external enable signal and processes image data using the internal enable signal. The timing controller determines a width of each of the plurality of pulses of the external enable signal and subtracts a predetermined reference value from the count value to generate a control signal faster than an effective period of the external enable signal. The control signal is applied to a driver which drives a display panel on which an image is displayed. In an exemplary embodiment, the control signal serves as a vertical start signal which starts an operation of a gate driver applying a gate signal to the display panel, thus preventing or effectively eliminating a delay of the image data applied to the display panel.

  • Patent number: 8451262
    Abstract: Disclosed is a method of driving a display panel, which includes a plurality of data lines, a plurality of gate lines, a first pixel column electrically connected to an N-th gate line and a second pixel column electrically connected to an (N+1)-th gate line adjacent to the N-th gate line (wherein N is a natural number). In the method, compensation data of the first pixel for compensating for a kickback deviation between the first and second pixel columns is generated using first data and second data corresponding to the first and second pixel columns, respectively. The compensation data of the first pixel column and the second data of the second pixel column are converted to data voltages of an analog type to output the data voltages to the data lines.
