AI Technical Summary

Benefits of technology

This patented technology allows for efficient reduction of electrical power fluctuations when controlling multiple lights emitted from an array of pixels simultanously without causing any damage over time. It also improves image quality through reducing variations between different colors produced at specific points within the displayed images.

Problems solved by technology

Technological Problem addressed in this patented text relates to improving the performance (fidelity) and stability of LED displays used in displaying images without causing any instability over longer periods due to increased currents caused by multiple columns of lights emitted from individual pixel elements located next to one another. Current methods require complex wiring patterns between different parts within the panel, making it difficult to achieve desired results.
