Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED light source modules in electronic devices suffer from light-blurring due to refraction and diffusion of light by coloring and internal materials, which current methods struggle to minimize effectively due to design and economic constraints.
Innovation Solution
An optical module with a light-emitting portion and a display surface featuring a first transmission region with a path-changing member, such as a convex lens, and a second surface that receives the transmitted light to prevent light-blurring by condensing and directing the light efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the thickness and structure of coloring coating materials or internal materials are adjusted to minimize light-blurring, then light transmission quality is improved, but design complexity and manufacturing cost increase
Solution Approach 1:
The display surface is segmented into distinct functional regions: a first transmission region for light transmission and a first blocking region for light blocking. This segmentation allows each region to be optimized independently for its specific function, improving light transmission quality without increasing overall design complexity.
Solution Approach 2:
A path changing member (convex lens) is introduced as an intermediary element between the light-emitting portion and the display surface. This intermediary condenses and directs light to the transmission region, improving light transmission quality while maintaining simple design and manufacturing processes.
2Illumination intensity
If the thickness and structure of materials are adjusted to prevent light-blurring, then visual effect is improved, but manufacturing cost increases
Solution Approach 1:
The display surface is divided into a first transmission region and a first blocking region, allowing simple manufacturing processes to create distinct functional zones without requiring complex material adjustments. The blocking region can be created through straightforward surface treatment.
Solution Approach 2:
The path changing member (convex lens) serves as a simple intermediary component that can be easily manufactured and integrated. It provides effective light condensation and direction without requiring complex or expensive material adjustments, thus maintaining ease of manufacture while improving visual effect.
3Illumination intensity
If light is transmitted through multiple materials, then light transmission is achieved, but light loss due to refraction and reflection increases
Solution Approach 1:
A path changing member (convex lens) is introduced as an intermediary to condense and direct light to the transmission region. This reduces the number of refraction and reflection interfaces by optimizing the light path, thereby minimizing light loss while maintaining effective light transmission.
Solution Approach 2:
The refractive index and shape parameters of the path changing member are optimized to control light propagation. By carefully selecting these parameters, the system achieves efficient light transmission with minimal refraction and reflection losses.

AI summary
An optical module includes a light-emitting portion for emitting light and a display including a first surface having a first transmission region through which at least a portion of the light emitted from the light-emitting portion is transmitted and a first blocking region which is surface-treated to block transmission of the light, and a second surface which the light transmitted through the first transmission region reaches to deliver an image to a user, wherein the first transmission region may include a path changing member for changing a propagation path of the transmitted light.
