Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light blocking member is placed at the interface between display substrate and light blocking portion, then external light reflection is reduced, but device complexity increases
Solution Approach 1:
A light blocking member comprising a base resin and black organic pigment or yellow pigment is introduced as an intermediary layer between the display substrate and the light blocking portion. This mediator absorbs or blocks external light before it reaches the interface, preventing reflection without requiring complex multi-layer structures or specialized coatings.
Solution Approach 2:
The optical properties of the light blocking member are optimized by adjusting the concentration and type of pigment (black organic pigment or yellow pigment) dispersed in the base resin. By changing these parameters, the member effectively absorbs external light across different wavelength ranges, reducing reflection without increasing structural complexity.
2Object-affected harmful factors
If pigment concentration in light blocking member is increased, then external light absorption is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes pigment concentration within specific ranges to achieve effective light absorption while maintaining manufacturability. By carefully controlling these parameters during manufacturing, the patent balances optical performance with production feasibility, avoiding excessive precision requirements.
