Display Panel Light-Emitting Layout for Edge Brightness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with display functions often experience uneven brightness at the edges due to the physical characteristics of light-emitting elements, leading to a negative user experience.
Innovation Solution
The electronic device incorporates light-emitting assemblies with different light-emitting patterns, where the edge region has a higher density of light-emitting elements and specific tuning elements to concentrate light, while the central region has a lower density with scattered light emission, reducing brightness differences across the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light-emitting elements are uniformly distributed across the display panel, then the device structure is simple and easy to manufacture, but the brightness becomes uneven at the edges leading to poor user experience
Solution Approach 1:
The patent applies local quality by differentiating the density of light-emitting elements between the central region and edge regions of the display panel. Specifically, the edge regions have a higher density of light-emitting elements compared to the central region, creating non-uniform local characteristics that compensate for the natural light fall-off at the edges and achieve overall brightness uniformity across the display panel.
2Illumination intensity
If light-emitting elements are densely packed in the edge region, then the brightness uniformity is improved, but the device complexity increases due to different light-emitting patterns required
Solution Approach 1:
The patent applies parameter changes by modifying the density parameter of light-emitting elements in different regions of the display panel. The edge regions are configured with a higher density of light-emitting elements, while the central region has a lower density. This parameter variation allows the system to achieve brightness uniformity without requiring fundamentally different light-emitting structures, thereby managing complexity through controlled parameter adjustment rather than structural complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances display uniformity and user experience by reducing uneven brightness, particularly at viewing angles, by concentrating light in the edge regions and maintaining dispersion in the central region.
Implementation Method 1
The electronic device includes a plurality of light-emitting assemblies disposed on the substrate, and each of the light-emitting assemblies includes a tuning element and a light-emitting element

AI summary
An electronic device is provided. The electronic device includes a substrate and a plurality of light-emitting assemblies. The substrate includes a first edge, an edge region, and a central region. The edge region is adjacent to the first edge. The central region is adjacent to the edge region and away from the first edge. The light-emitting assemblies are disposed on the substrate, and each of the light-emitting assemblies has a tuning element and a light-emitting element. The light-emitting assemblies further include a first light-emitting assembly and a second light-emitting assembly. The first light-emitting assembly is disposed in the central region and has a first light-emitting pattern. The second light-emitting assembly is disposed in the edge region and has a second light-emitting pattern. At a viewing angle of 60°, the brightness of the first light-emitting pattern is higher than the brightness of the second light-emitting pattern.
