METHOD AND DEVICE FOR RESIDUAL IMAGE TEST AND ELIMINATION

摘要

A method and device for residual image test and elimination are provided. The method and the device can solve the problems that the existing assessment of the residual image is not accurate and the residual image can not be accurately corrected. The method for residual image test includes：a residual image test picture is played by a display panel(S101); a first fixed electrical level signal is loaded into a pixel electrode of the display panel (S102); electric potential information of the pixel electrode is obtained through a data line (S103).
