Title:
METHOD, APPARATUS AND SYSTEM FOR DETERMINING LIGHT LEAKAGE DEGREE OF DISPLAY PANEL, AND TEST FIXTURE
Document Type and Number:
WIPO Patent Application WO/2022/193102
Kind Code:
A1
Abstract:
A method, apparatus and system for determining the light leakage degree of a display panel, and a test fixture. The method comprises: when it is detected that there is a light leakage sub-region among multiple sub-regions comprised in a display panel, a light leakage testing device determining the light leakage degree of the display panel on the basis of an average value of luminance of the multiple sub-regions and luminance of the light leakage sub-region. By means of the method, compared with a method in which test personnel manually determine a light leakage degree, a light leakage testing device can automatically determine the light leakage degree of a display panel on the basis of the luminance of a sub-region, thus effectively improving the reliability and accuracy of determining the light leakage degree of the display panel.
