Quantum Dot Pixel Definition Sides for Display Panel Light Efficiency

The patent converts the harmful light loss toward both sides of the display panel into a beneficial effect by placing quantum dot materials on the pixel definition portions. These quantum dot materials convert the otherwise wasted light into useful colored light that contributes to the display output, thereby improving luminous efficiency while maintaining the wide color gamut advantage.

The patent applies quantum dot materials specifically on the pixel definition portions rather than uniformly across the entire panel. This localized application targets the specific areas where light is lost, converting the wasted light into useful emission only where needed, thus improving overall luminous efficiency without compromising the color performance of the main light-emitting areas.

The patent merges the pixel definition portions with quantum dot functional layers by integrating the quantum dot materials directly onto the pixel definition portions during the manufacturing process. This combination eliminates the need for separate quantum dot layers and simplifies the overall structure while achieving the dual function of light emission and light management.

The pixel definition portions serve multiple functions: they define the pixel boundaries, manage light direction, and now also contain quantum dot materials for light conversion. This multi-functionality reduces the need for additional separate components, thereby improving luminous intensity without proportionally increasing device complexity.
