Light-Emitting Device Design for Improved Flexibility and Precision
Here’s PatSnap Eureka !
Summary
Problems
Existing flexible light-emitting devices face challenges in achieving a novel structure that allows for efficient light emission and distribution, particularly in aligning electrodes to prevent mask deformation during deposition and ensuring uniform light transmission and reflection.
Innovation solutions
A light-emitting device with a substrate featuring first and second electrodes extending in different directions, where specific regions on the substrate allow for non-intersecting electrodes, enabling favorable deposition and light transmission, and a light-emitting module incorporating reflecting members to enhance light emission patterns.

General conflict description:
Principle concept:
If masks with bending portions are used for electrode deposition on flexible substrates, then the substrate flexibility is maintained, but the mask deforms under gravity causing poor deposition accuracy and electrode pattern uniformity
Why choose this principle:
The substrate surface is divided into multiple regions (first region, second region, third region) with different electrode configurations. Second electrodes of a first group extend in a first direction in the first region, while second electrodes of a second group extend in a second direction intersecting the first direction in the second region. This segmentation allows different electrode patterns to be formed without requiring mask bending portions, thereby maintaining both substrate flexibility and deposition accuracy.
Principle concept:
If masks with bending portions are used for electrode deposition on flexible substrates, then the substrate flexibility is maintained, but the mask deforms under gravity causing poor deposition accuracy and electrode pattern uniformity
Why choose this principle:
The electrode configuration uses asymmetric arrangements where electrodes in different regions extend in different directions. The first group of second electrodes extends in a first direction while the second group extends in a second direction intersecting the first direction. This asymmetric design eliminates the need for symmetric mask bending portions that would deform under gravity, thus improving deposition accuracy while maintaining substrate flexibility.

Abstract
A plurality of light-emitting devices ( 10 ) include a plurality of light-emitting devices ( 10 a ), a plurality of light-emitting devices ( 10 b ), and a plurality of light-emitting devices ( 10 c ). The plurality of light-emitting devices ( 10 ) are aligned on a reflecting member ( 20 ). Six light-emitting devices ( 10 c ) are aligned in a straight line along one direction. Four light-emitting devices ( 10 b ) are aligned surrounding a region facing one ends of the six light-emitting devices ( 10 c ). Each of four light-emitting devices ( 10 a ) are aligned with each of the four light-emitting devices ( 10 b ) outside the four light-emitting devices ( 10 b ).
