Abstract
A method is provided for adjusting a viewing angle for a dark state of a display panel, and the method includes steps of: obtaining a first brightness change of a to-be-tested panel at a first viewing angle under a condition of a first voltage difference; obtaining a second brightness change of the to-be-tested panel at a second viewing angle under the condition of the first voltage difference; obtaining a ratio of the second brightness change to the first brightness change; and comparing the ratio of the second brightness change to the first brightness change with a first threshold to determine whether the first voltage difference is a selection voltage of the display panel.
