Claim Text:
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 D 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 D
