    Area of Science:

    • Display technology
    • Optical metrology
    • Image quality assessment

    Background:

    • Accurate measurement of contrast modulation is crucial for evaluating pixelated display performance.
    • Existing methods may face challenges due to the discrete nature of display pixels.

    Purpose of the Study:

    • To investigate the constraints affecting contrast modulation and line-pair luminance modulation measurements in pixelated displays.
    • To identify key factors influencing measurement precision and accuracy.

    Main Methods:

    • Simulations were conducted to analyze the impact of spatial misalignment between display pixels and the light measuring device (LMD) detector array.
    • The study evaluated the effect of the pixel ratio on measurement accuracy.

    Main Results:

    • Measurement precision is significantly influenced by the offset between display pixels and the LMD detector array.
    • Inadequate spatial imaging performance of the LMD leads to underestimation of contrast modulation.
    • A higher pixel ratio (measurement device pixels per display pixel interval) is necessary for improved measurement accuracy.

    Conclusions:

    • The accuracy of contrast modulation measurements is constrained by pixel alignment and LMD spatial imaging capabilities.
    • Determining the optimal pixel ratio for accurate measurements is complex and depends on the specific display device architecture.
