  • Compensation method, system, device and medium of IR drop of display panel
    Patent number: 12266311
    Abstract: The disclosure provides a compensation method, system, device and medium of a IR Drop of a display panel. The compensation method includes: constructing a IR Drop model of the display panel based on a distribution of equivalent resistances between adjacent pixels in the display panel; constructing a vector matrix equation of the IR Drop according to the IR Drop model; performing an equivalent processing on the vector matrix equation of the IR Drop to form a plurality of equivalent sub-matrices; iteratively solving IR Drop data of each node in each equivalent sub-matrix; and performing a voltage compensation on each pixel in the display panel according to the IR Drop data. The disclosure may realize a point-to-point accurate compensation of all nodes in the display panel, and improves a problem of uneven brightness of a high-resolution display panel caused by the IR Drop.
