The present disclosure provides a method, an apparatus and a system for determining a light-leakage degree of a display panel, and a test fixture, and relates to the field of display technologies. When a light-leakage detection device detected that the plurality of sub-regions includes at least one light-leakage sub-region, the light-leakage detection device can determine a light-leakage degree of the display panel based on an average of brightness values of the plurality of sub-regions and a brightness value of the light-leakage sub-region. Compared with a way that an inspector manually determines a light-leakage degree, the light-leakage detection device can automatically determine the light-leakage degree of the display panel based on brightness values of the sub-regions by the method according to the embodiment of the present disclosure, thereby effectively improving the reliability and accuracy of the light-leakage degree of the display panel as determined.

The present disclosure provides an evaluation index calculation device, an evaluation index calculation method, and an evaluation index calculation program which are capable of diversifying an evaluation index representing an optical state of a light control sheet.

Methods, apparatus, and systems for mitigating pinhole defects in optical devices such as electrochromic windows. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible. In some cases, the pinhole defect may be the result of mitigating a short-related defect
