37‐4: Research on the Measurement Method of Halo Effect in HDR LCD Displays

Based on the instantaneous dynamic range of the human eye to light, this paper proposes a high‐precision and efficient measurement method for the halo effect through the ratio of the halo area. By studying the error factors of imaging luminance meter used for the halo effect measurement, an improvement method is put forward. The consistency of the measurement results between the new method and the traditional masking method is verified through measurement results comparison. And the technical characteristics and advantages of the new measurement method are discussed and summarized.
