Abstract
Embodiments of the present invention provide a device and a method for testing transparency effect of a transparent display substrate. The device comprises a transparency identification module, an optical measurement unit and a reference object including two kinds of regions of different colors. The optical measurement unit is able to directly measure brightness of the two kinds of regions of different colors of the reference object to acquire a first brightness difference, and to measure brightness of the two kinds of regions of different colors of the reference object through the transparent display substrate to acquire a second brightness difference. Based on the first brightness difference and the second brightness difference, the transparency identification module calculates identification degree ID of the transparent display substrate according to the equation: where ΔLis the first brightness difference and ΔLis the second brightness difference. Embodiments of the present invention may eliminate the influence of ambient light on the test and increase the test accuracy of the transparent display substrate.
