  "title": "How to Fix Color Uniformity in Digital Screens Using Math",
  "original_title": "System and method for calibrating a display panel",
  "summary": "A method for smoothing out color and brightness inconsistencies across a display screen by mathematically adjusting pixels based on their distance from a reference point.",
  "what_it_does": "This patent describes a way to fix color unevenness in displays by using a mathematical model to adjust pixel values. The system defines a 'calibration vector' that includes a reference pixel, a calibration volume (the intensity of the fix), and a range (how far the fix spreads). The processor finds pixels that match the reference color, calculates how far they are from that reference, and applies a correction based on that distance. This allows the display to automatically smooth out color gradients or fix blotchy areas by applying different weights to pixels depending on their proximity to the target reference point.",
  "what_it_does_not_cover": [
    "Does not cover hardware-based physical display repair or panel replacement.",
    "Does not cover image processing techniques that adjust the entire screen globally without reference to specific pixel-to-pixel distance calculations.",
    "Does not cover non-digital display technologies like mechanical flip-dot displays."

  "abstract": "The present disclosure provides a system and method for calibrating a display panel. The system includes a display panel including a pixel array and a controller. The processor is configured to, upon executing instructions: define a calibration vector with a source pixel, a vector volume, and a calibration range; calculate a distance between a pixel to be calibrated and the source pixel; calculate a calibration amount based on the distance and the vector volume; and calibrate the pixel to be calibrated based on the calibration amount and the calibration vector.",
