Display Pixel Transfer by Optical Binning for Color Uniformity

The patent segments light-emitting elements into different groups based on their optical characteristics (wavelength, luminance). By measuring and categorizing each element's properties, the system divides the homogeneous batch into heterogeneous groups that can be strategically assigned to different pixel locations to achieve target color points while maintaining overall uniformity.

The patent applies local quality by assigning specific optical characteristic combinations to specific pixel locations based on the display panel's color requirements. Different regions of the display may use different combinations of light-emitting elements with varying wavelengths and luminances to achieve the desired color point at each location, thereby maintaining overall color uniformity while utilizing diverse elements.

The patent changes the approach from using elements with identical parameters to using elements with varied parameters (wavelength, luminance). By measuring actual optical characteristics and using these parameters to determine assignment strategies, the system transforms the problem from one of uniformity to one of controlled diversity, where parameter variations are leveraged to achieve target color points.

The patent implements feedback by measuring the optical characteristics of each light-emitting element and using this information to determine its optimal assignment. The measurement results feed into an assignment algorithm that considers target color points and pixel requirements, creating a closed-loop system that optimizes both utilization rate and color uniformity based on actual element properties.
