Research on the measurement of micro display luminance

In order to meet the requirements of the micro display for the measurement of sub-pixel luminance and chromaticity parameters, this paper introduces the micro-objective into the imaging luminance meter scheme. A set of microscopic imaging luminance meter is designed and developed by using high resolution camera, XYZ color filter, micro-objective lens, and the micro level target is tested. The mobile phone screen, micro display and standard reticle are tested. The experimental results show that the luminance and chromaticity of samples with size less than one micron can be measured, when 31-megapixel resolution monochrome camera and 50 times micro lens are used. The luminance test error after calibration is less than 1%.
