1. A system for display, comprising:
a display panel comprising a pixel array; and
a processor configured to, upon executing instructions:
define a calibration vector with a source pixel, a vector volume, and a calibration range, wherein the calibration vector is configured to calibrate more than one pixel of the pixel array, wherein the source pixel is a parameter of grayscale values;
locate at least one center point from the pixel array for calibration based on the source pixel, wherein each center point of the at least one center point has a same grayscale value with the source pixel;
calculate a distance between each pixel and each center point;
calculate a calibration amount of a pixel to be calibrated based on the distance and the vector volume; and
calibrate the pixel to be calibrated based on the calibration amount and the calibration vector.
