Document Type and Number:
WIPO Patent Application WO/2022/000717
Kind Code:
A1
Abstract:
A method and apparatus for adjusting a dark-state view angle of a display panel, and an electronic device. The method comprises: acquiring a first brightness variation value, at a first voltage difference, for a panel to be tested (S10); acquiring a second brightness variation value, at the first voltage difference, for the panel to be tested (S20); acquiring a ratio of the second brightness variation value to the first brightness variation value (S30); and comparing the ratio of the second brightness variation value to the first brightness variation value with a first threshold, so as to determine whether the first voltage difference is a selected voltage for the display panel (S40).
