Display Panel Aperture Sizing for Fingerprint Sensor Brightness Uniformity

The patent applies local quality by differentiating aperture region sizes based on their functional requirements. First aperture regions (with FID sensors) have smaller areas, while third aperture regions (without FID sensors) have larger areas. Second aperture regions serve as transition zones with intermediate sizes. This localized differentiation allows the display to maintain both fingerprint sensing capability and brightness uniformity by compensating for the light-blocking effect of FID sensors through strategic aperture size variation in adjacent regions.

The patent segments the aperture regions into three distinct types based on their functional requirements: first aperture regions (smaller, with FID sensors), second aperture regions (intermediate size, transition zones), and third aperture regions (larger, without FID sensors). This segmentation allows each region to be optimized for its specific function while maintaining overall visual consistency. The gradual size progression from first to third aperture regions creates a transition that prevents abrupt visual changes, thereby achieving visual perception consistency without requiring all apertures to be identical.

The patent implements parameter changes by systematically varying the aperture region size parameter across different zones of the display. Specifically, the aperture areas progress from smaller first aperture regions (with FID sensors) to intermediate second aperture regions, and finally to larger third aperture regions (without FID sensors). This gradual parameter change compensates for the light-blocking effect of FID sensors and creates a more uniform brightness distribution across the display. The structured approach to parameter variation, organized in distinct zones, manages complexity by providing clear design guidelines for implementation.
