Crosstalk Testing for Special-Shaped Screens

The patent applies local quality by differentiating the testing approach for different regions of the screen. It identifies that special-shaped screens have non-uniform pixel structures and driving modes in different areas, so the crosstalk testing must be adapted to local characteristics rather than using a uniform method across the entire screen. This involves setting different test point locations and calculating crosstalk parameters specific to each region's structural features.

The patent segments the crosstalk testing process into multiple independent measurement and calculation steps. It divides the screen into multiple test point locations, measures luminance at each point separately, and calculates crosstalk parameters for each segment independently. This segmentation allows the complex testing of special-shaped screens to be broken down into manageable, accurate local measurements that can be aggregated for comprehensive evaluation.

The patent applies dynamics by making the testing method adaptive rather than static. It dynamically adjusts the testing parameters, test point locations, and calculation methods based on the actual screen structure, driving mode, and pixel arrangement detected during testing. This dynamic adaptation allows the same testing system to accurately handle both integrated screens and special-shaped screens with varying configurations.

The patent changes key testing parameters based on the screen type being tested. It modifies test point coordinates, luminance measurement thresholds, and crosstalk calculation formulas according to the detected pixel structure and driving mode. This parameter adaptation enables the testing method to maintain high precision across different screen configurations while preserving a universal testing framework.
