  • Patent number: 11158287
    Abstract: Embodiments of the present disclosure provide a system for display. The system includes a display having a plurality of pixels, a processor, and a control logic. The processor includes a graphics pipeline configured to generate a plurality of pieces of pixel data for the plurality of pixels and a pre-processing module configured to generate a plurality of pieces of compensation data for the pixel data and compress the compensation data. The compensation data is compressed by determining a plurality of pieces of quantified down-sampled compensation data based on the compensation data, converting the quantified down-sampled compensation data into M units of index data, and converting the M units of index data into M code streams. The control logic is operatively coupled to the display and the processor and includes a post-processing module configured to decompress the compressed compensation data based on the M code streams to provide control signals.

  • Patent number: 10891897
    Abstract: The present disclosure provides methods and systems for estimating and compensating the aging of light emitting elements in a display panel. In one example, a method for compensating aging of light emitting elements in a display panel is disclosed. A luminance target is determined based on historical luminance losses of a plurality of light emitting elements in the display panel. An adjusted luminance loss of one of the plurality of light emitting elements is determined based on a current and a luminance loss of the light emitting element. A compensation factor of the light emitting element is determined based on the adjusted luminance loss of the light emitting element and the luminance target. A compensated current is provided to the light emitting element based on the current and the compensation factor of the light emitting element.
