OLED Display Panel Gradual Pixel Density Transition

The patent applies local quality by creating a gradual pixel density transition zone between the display region and pixel region. The pixel density is adjusted locally in the pixel region to decrease gradually toward the center, rather than maintaining uniform density throughout. This local variation in pixel density creates a smooth transition that eliminates the abrupt luminous efficiency difference while still reserving space for sensor elements in the cutting area.

The patent applies parameter changes by systematically varying the pixel density parameter across the pixel region. Instead of maintaining a constant pixel density, the patent creates a gradient where pixel density decreases gradually from the display region toward the center of the pixel region. This parameter variation allows the structure to provide space for sensor elements while maintaining appropriate luminous efficiency through the gradual transition.

The patent applies segmentation by dividing the pixel region into zones with different pixel density characteristics. The pixel region is segmented such that areas closer to the display region maintain higher pixel density for display quality, while areas toward the center have gradually reduced pixel density. This segmentation creates space for sensor elements in the cutting area while preserving display quality in the relevant display areas.
