PIXEL POSITIONING METHOD, APPARATUS, AND DEVICE FOR CURVED SCREEN

WIPO Patent Application WO/2023/221290

A1

The present invention provides a pixel positioning method, apparatus, and device for a curved screen. The method comprises: obtaining a photographed standard spring molecular lattice image displayed by a curved screen as a photographed image; establishing spring molecular systems in the photographed image, and matching the photographed image with the standard spring molecular lattice image; adjusting the spring molecular systems to a steady state to obtain a calibration image; and constructing a mapping model between the calibration image and the standard spring molecular lattice image. Thus, errors of image distortion on a curved screen are compensated for.
