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.

The present disclosure provides a method for determining an overdrive mapping correlation in a display panel. The method includes the following steps. First, a repeating subpixel arrangement is determined. The subpixel arrangement includes at least three sets of subpixels in the display panel. An ideal luminance value of a pattern of the subpixel arrangement is then determined. The pattern includes at least a first set of subpixels displaying a zero pixel value, a second set of subpixels displaying a first nonzero pixel value, and a third set of subpixels displaying a second nonzero pixel value, the first, second and third sets of subpixels respectively arranged one after another. The first nonzero pixel value may be different from the second nonzero gray scale value. An actual luminance value of the pattern of the subpixel arrangement is then determined. An overdrive pixel value is further determined.

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.

The present disclosure provides a method for determining a grayscale mapping correlation in a display panel. The method includes the following operations. First, a target first luminance value of the display panel is determined. A first set of start pixel values of a first attribute of a first grayscale value is determined based on the first grayscale value and the target first luminance value of the display panel. A first set of mapped pixel values of the first attribute mapped to the first grayscale value, and a first mapped luminance value are then determined based on the first set of start pixel values of the first attribute and a set of first target values of a second attribute. The set of first target values of the second attribute include a plurality of target chrominance values and the target first luminance value.
