Abstract: 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.

Abstract: A plastic frame includes a first frame having a first frame surface and a first end portion and a second end portion opposite to each other, and a second frame having a second frame surface, an end portion of the second frame being connected to the first end portion of the first frame. The first frame surface and the second frame surface are located on the same side of the plastic frame. A first height difference between the first frame surface at a first end portion of the first frame and the second frame surface is smaller than a height difference between the first frame surface at a middle portion of the first frame and the second frame surface. The first height difference may be, for example, 0.1-0.3 mm.
