  • Publication number: 20230314223
    Abstract: A chromaticity measurement method and device for calibration of a tiled LED display screen (A) having the advantages of convenience in operation and accurate measurement. The chromaticity measurement method includes: imaging emergent light from the tiled LED display screen (A) with an objective lens (1); receiving a light beam from the objective lens (1) with a transflective lens (2) and performing beam splitting to obtain a first light beam and a second light beam; receiving the first light beam with an imaging sensor (3) to obtain an original image; receiving the second light beam in a two-dimensional lattice form with a movable optical fiber array coupling device (4), and converting the second light beam into one-dimensional lattice light; and obtaining chromaticity information and spectrum information of a plurality of regions on the tiled LED display screen (A) according to the one-dimensional lattice light with a spectrum acquisition device (5).
