  • Circuit for compensating a ripple, method of driving display panel using the circuit and display apparatus having the circuit
    Patent number: 9601077
    Abstract: A circuit includes a reference signal generating part configured to generate a plurality of reference signals having levels different from each other, a comparing part configured to compare a ripple signal with the reference signals to determine a level of the ripple signal, a compensating signal generating part configured to generate a compensation ripple signal corresponding to the level of the ripple signal, where the compensation ripple signal has a phase opposite to the ripple signal, and a push-pull circuit configured to stabilize the compensation ripple signal.

  • Timing control apparatus and display device having the same
    Patent number: 8847871
    Abstract: A timing control apparatus includes a memory part, a multi-timing control part, and a power supply part. The memory part stores data. The multi-timing control part includes a plurality of timing controllers that sequentially read the stored data from the memory part in response to a reset signal, and outputs a power control signal that controls an output timing of a power. The power supply part outputs the power in response to the power control signal.
