1Illumination intensity
If direct-light type LED light-emitting component is used, then lightness is improved, but thickness increases
Solution Approach 1:
The patent merges the LED light source and light guide plate into a single integrated light-emitting component structure. The light-emitting component includes a substrate, LED array, and light guide layer that work together as one unified module, eliminating the need for separate components and reducing overall thickness while maintaining lightness.
Solution Approach 2:
The patent uses a thin light guide layer and flexible substrate to create a compact light-emitting component. The light guide layer is designed as a thin film structure that can efficiently distribute light while occupying minimal space, thereby reducing the thickness of the display device.
2Illumination intensity
If LED array and light guide plate are used, then light emission is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple functional elements (substrate, LED array, light guide layer, and encapsulation layer) into a single integrated light-emitting component. This merging reduces the number of separate parts and simplifies the overall device structure while maintaining effective light emission functionality.
Solution Approach 2:
The light-emitting component is designed as a multi-functional module that simultaneously provides light emission, light distribution, and structural support. The integrated structure serves multiple purposes, reducing the need for additional separate components and simplifying the overall device architecture.
