Reflective Light-Emitting Panel Layout for Light Leakage Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting panels suffer from low light utilization rates and high power consumption due to light leakage and the need for higher voltages or currents to achieve high luminance, which is not conducive to low power consumption.
Innovation Solution
The light-emitting panel incorporates a first reflective layer with hollow portions for light-emitting elements and a second reflective portion covering gaps between the elements and the first reflective layer to reflect leaked light, improving light utilization and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If higher voltage or current is provided to achieve high luminance, then display luminance is improved, but power consumption increases
Solution Approach 1:
The patent converts the harmful light leakage that occurs in gaps between light-emitting elements and the reflective layer into a beneficial resource by introducing a second reflective portion. This second reflective layer captures the leaked light and redirects it toward the display surface, transforming what was previously wasted light into useful illumination, thereby improving luminance without increasing power consumption
Solution Approach 2:
The patent recovers light that would otherwise be discarded through the gaps between light-emitting elements and the first reflective layer. The second reflective portion positioned at the bottom of hollow portions intercepts this leaked light and reflects it back upward, effectively recovering and reutilizing light energy that would have been lost, thus improving overall light utilization efficiency
2Loss of energy
If light-emitting elements are arranged closely to improve light utilization, then light leakage is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the reflective structure into two distinct parts: a first reflective layer positioned above the light-emitting elements and a second reflective portion positioned at the bottom of hollow portions below the light-emitting elements. This segmentation allows each reflective component to perform its specific function independently, effectively capturing light from different directions and reducing the need for extremely tight spacing between elements
Solution Approach 2:
The second reflective portion acts as an intermediary structure that mediates between the light-emitting elements and the base substrate. It specifically addresses the light leakage problem in the vertical direction by intercepting and redirecting leaked light, thereby solving the light utilization issue without imposing stringent requirements on horizontal positioning precision

Function Achieved in This Case
This design enhances light utilization, improves display luminance, and reduces power consumption by reusing otherwise lost light, allowing for high luminance without the need for increased display signals.
Implementation Method 1
