A device and method for testing a transparency effect of a transparent display substrate (25). The device comprises a transparency identification module (21), an optical measurement apparatus (22) and a reference (23) comprising two different colours of regions. The optical measurement apparatus (22) can directly measure the brightness of the two different colours of regions of the reference (23), so as to acquire a first brightness difference, and measure the brightness of the two different colours of regions of the reference (23) through a transparent display substrate (25), so as to acquire a second brightness difference. The transparency identification module (21) calculates the identification degree ID of the transparent display substrate (25) according to the first brightness difference and the second brightness difference, and the calculation formula is: ID = ΔL2 / ΔL1 X 100%, where ΔL1 is the first brightness difference, and ΔL2 is the second brightness difference. The device and method can eliminate the influence of ambient light on testing, and improve the testing accuracy of a transparent display substrate (25). |
