Solution Overview

Problem

Light interference at the side surfaces of adjacent light emitting modules in display apparatuses causes bright lines or dark lines at the boundaries between modules, affecting display quality.

Innovation Solution

The light emitting apparatus includes at least two light emitting modules with spaced apart side surfaces forming a separation zone and inclined planes, and a variable width zone to prevent light interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If light emitting modules are disposed adjacent each other to form a compact display apparatus, then the display area is increased and space utilization is improved, but light interference occurs at the side surfaces causing bright lines or dark lines at boundaries

Engineering Contradiction:

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

A light blocking structure is introduced as an intermediary element between adjacent light emitting modules. This structure selectively blocks light traveling along oblique paths from the side surfaces of first light emitting modules, preventing the light interference that causes bright and dark lines at module boundaries, while maintaining the compact adjacent arrangement for maximum display area utilization.

Principle #24Intermediary (Mediator)

2Manufacturing precision

If light blocking structures are added to prevent bright lines and dark lines, then display quality is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The light blocking structure is designed with local quality by positioning it specifically at critical regions where light interference occurs at module boundaries. The structure has varying light blocking properties at different locations - with higher blocking capability at side surfaces where oblique light paths cause interference, and reduced blocking at other areas. This localized approach achieves display quality improvement without uniformly increasing device complexity throughout the entire structure.
