Device and method for detecting light-emitting element

Abstract

The invention provides a detection device and method of a light-emitting element. The detection equipment is used for simultaneously detecting the light emitting characteristics of a plurality of light emitting elements, and comprises a plurality of optical filters, the transmittance curves of the plurality of optical filters are different, and when the plurality of light emitting elements emit light at the same time, the spectrums filtered by different optical filters are different; the light acquisition module is configured to respectively obtain gray level images of the plurality of light-emitting elements which are filtered by the plurality of light filters under the condition that the plurality of light-emitting elements emit light at the same time; the processing module is configured to determine characteristic values of light-emitting characteristics of the plurality of light-emitting elements according to the grayscale images of the plurality of light-emitting elements filtered by the plurality of light filters; wherein the light-emitting characteristics of the light-emitting element comprise at least one of dominant wavelength, peak wavelength and half-peak width. The detection equipment is high in detection efficiency.
