Mini-LED显示屏空间光色参数计量装置的建立OA

As a new high-resolution display technology,the accurate measurement of spatial light and color parameters of Mini-LED displays is one of the core requirements for ensuring product performance and driving industry standardization.To address the limitations of existing photometric equipment in production-line testing capabilities,this study develops a dedicated measurement system for spatial light color parameters of Mini-LED displays.Based on a multi-dimensional displacement stage and a spectroradiometer,this device achieves high-resolution sampling of the spatial luminance and chromaticity distribution of the display screen.Simultaneously,a software system integrating motion control and synchronous data acquisition was developed as a supporting component,which significantly improves the efficiency of testing and data processing,and can generate measurement results in accordance with different standards.The relative expanded uncertainty of the luminance measurement for this device is Urel=2.4%(k=2),and the expanded uncertainty of the chromaticity coordinates measurement is 0.0024(k=2).It can meet the metrology requirements for the spatial light and color parameters of Mini-LED displays,and will provide robust metrology testing support for quality control,standard formulation,and technological research and development in the Mini-LED industry.
