Light Adjusting Layer Layout for Uniform LED Emission

The patent applies local quality by introducing a light adjusting layer with spatially varying properties. The layer has different thicknesses in different regions: a first thickness in the damaged edge region and a second thickness in the non-damaged central region. This local variation in thickness allows the layer to compensate for the damaged regions specifically, adjusting the light emission locally to achieve uniform overall light distribution while maintaining the reduced size of the light emitting unit for high resolution.

The patent applies parameter changes by modifying the thickness parameter of the light adjusting layer to control light emission. The layer has a first thickness in the damaged region and a second thickness in the non-damaged region, with the first thickness being greater than the second thickness. This parameter variation in thickness allows the layer to reduce the excessive light from damaged regions while maintaining sufficient light output from healthy regions, thereby increasing overall light output while preserving high resolution.

The light adjusting layer serves multiple functions simultaneously: it acts as an optical compensation layer to correct damaged regions, functions as an encapsulation layer to protect the light emitting unit, and can also serve as part of the packaging structure. This multi-functionality allows the device to achieve uniform light emission without adding significant structural complexity, as the same layer performs multiple roles rather than requiring separate components for each function.
