  • Pixel and display device including the same
    Patent number: 12223901
    Abstract: A pixel of a display device may pre-charge a light emitting element in non-emission periods immediately before emission periods by varying a voltage level of an initialization voltage. As a result, a luminance non-uniformity phenomenon that may occur as the result of a deterioration deviation of the light emitting element may be removed or reduced.

  • Apparatus for compensating for phase difference attendant upon time division multiplexing and method thereof
    Patent number: 6959012
    Abstract: An apparatus and method is provided for compensating for the difference between the phase relation among signals at the point of generation and the phase relation among the signals after time division multiplexing when the signals are processed according to the time division multiplexing. In a system which transmits a plurality of signals according to the time division multiplexing, the apparatus includes a phase transition filter group having as many phase transition filters as the plurality of signals. Each of the phase transition filters performs filtering to generate a signal having a phase transited with respect to an input signal based on phase information. The apparatus also includes a multiplexing unit for providing phase information, which are assigned to each of the plurality of signals according to the time division multiplexing, to the phase transition filter group and time division multiplexing a plurality of signals transmitted from the phase transition filter group.
