Abstract

The application relates to a transparent display optical property measuring device and a measuring method. The transparent display optical property measuring device comprises a first hollow sphere and a second hollow sphere, light sources are arranged in the first hollow sphere and the second hollow sphere, a diffuse reflection layer is arranged on the inner wall of the first hollow sphere and the second hollow sphere, and a brightness meter is arranged on at least one of the first hollow sphere and the second hollow sphere; a mounting space for mounting a transparent display is arranged between the first hollow sphere and the second hollow sphere; a first light transmission hole penetrating the ball wall of the first hollow sphere is arranged on the first hollow sphere, and a second light transmission hole penetrating the ball wall of the second hollow sphere is arranged on the second hollow sphere; the first light transmission hole, the mounting space and the second light transmission hole form a light transmission channel through which light can pass. The transparent display optical property measuring device can solve the problem that the measurement result obtained when the traditional display measuring device is applied to a transparent display is inaccurate.
