Light Emitting Module Boundary Structure for Uniform Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light interference at the side surfaces of adjacent light emitting modules in display apparatuses leads to the formation of bright or dark lines at the boundaries between modules, affecting display quality.
Innovation Solution
The light emitting apparatus features at least two modules with spaced apart side surfaces forming a separation zone and inclined planes, along with a variable width zone, to prevent light emission at the boundaries, thereby eliminating the appearance of bright or dark lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If light emitting modules are disposed adjacent each other to form a display apparatus, then the display area is increased, but light interference occurs at the side surfaces causing bright or dark lines at boundaries
Solution Approach 1:
A light blocking structure is introduced as an intermediary element between adjacent light emitting modules. This structure includes a light blocking layer disposed at the side surfaces of the modules, which actively blocks light from escaping at the boundaries and prevents interference with adjacent modules, thereby eliminating bright or dark lines while maintaining the continuous display area
Solution Approach 2:
The harmful light emission at side surfaces is extracted and blocked by the light blocking structure. By specifically targeting and removing the problematic light paths at the boundaries through the light blocking layer, the solution prevents light interference without affecting the overall display functionality
2Object-affected harmful factors
If side surfaces of adjacent light emitting modules are spaced apart to form a separation zone, then light interference is reduced, but the overall device complexity increases
Solution Approach 1:
Instead of spacing apart the entire modules which would increase complexity, the light blocking structure is applied partially only at the critical side surface regions where light interference occurs. This partial application effectively reduces light interference while maintaining simple module arrangement and minimal increase in device complexity
3Object-affected harmful factors
If inclined planes are formed on side surfaces of light emitting modules, then light emission at boundaries is blocked, but manufacturing precision requirements increase
Solution Approach 1:
The mechanical approach of forming inclined planes on side surfaces is replaced with a light blocking layer that can be applied through standard coating or lamination processes. This substitution eliminates the need for precise mechanical machining of inclined planes while achieving the same goal of blocking boundary light emission, thereby reducing manufacturing precision requirements
