1. A detecting method of a transparent display panel, comprising:
providing a reference pattern sheet having a plurality of first regions and a plurality of second regions alternately arranged in a first direction, wherein each of the first regions has a first color, each of the second regions has a second color different from the first color, each of the first regions and each of the second regions have a same predetermined width D in the first direction, and the reference pattern sheet has n pairs of the first regions and the second regions in the first direction; forming a uniform predetermined illuminance on the reference pattern sheet by irradiating the reference pattern sheet with a light source; detecting directly the reference pattern sheet by a measuring device separated from the reference pattern sheet by a predetermined distance so as to obtain a value measured without panel DPi of a sum of the predetermined widths of each pair of the first region and the second region of the reference pattern sheet, where i=1, . . . , n, and n is a positive integer; placing the transparent display panel between the measuring device and the reference pattern sheet; detecting the reference pattern sheet through the transparent display panel having no image displayed by the measuring device so as to obtain a first value measured with panel D1i of the predetermined width of each first region of the reference pattern sheet and a second value measured with panel D2i of the predetermined width of each second regions of the reference pattern sheet, where i=1, . . . , n; and determining a clarity C of the transparent display panel according to a ratio of a sum of each pair of the first value measured with panel D1i and the second value measured with panel D2i to the value measured without panel DPi of the sum of the predetermined widths of each pair of the first region and the second region, wherein the clarity C of the transparent display panel is linearly proportional to the ratio. |
