Abstract: A method for detecting a clarity of a transparent display panel and a detecting apparatus thereof are provided. The detecting method includes: detecting directly a reference pattern sheet by a measuring device to obtain a without-panel measurement value of the reference pattern sheet; placing the transparent display panel between the measuring device and the reference pattern sheet; detecting the reference pattern sheet through the transparent display panel to obtain a with-panel measurement value of the reference pattern sheet; acquiring clarity of the transparent display panel according to the without-panel and with-panel measurement value; wherein, the reference pattern sheet includes a plurality of pattern groups sequentially arranged in a first direction, each of which includes a first region and a second region, and widths of the plurality of pattern groups in the first direction are different. The detecting method can better evaluate a transparent effect of the transparent display panel.

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: ID = Δ   L 2 Δ   L 1 × 100  % , where ΔL1 is the first brightness difference and ΔL2 is 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.
