Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Micro LED display panels suffer from light crosstalk between adjacent pixels, leading to poor display effects due to interference from reflected light.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light-emitting devices are closely arranged in an array to achieve ultra-high resolution, then the resolution is improved, but light crosstalk between adjacent pixels occurs causing poor display effects
Solution Approach 1:
A light-absorbing layer is introduced as an intermediary component between adjacent light-emitting devices. This layer selectively absorbs stray light emitted by individual pixels, preventing the light from reaching adjacent pixels and causing crosstalk. The light-absorbing layer acts as a mediator that blocks harmful light interference while maintaining the closely-arranged pixel structure needed for ultra-high resolution
Solution Approach 2:
The patent converts the harmful effect of stray light emission from light-emitting devices into a beneficial outcome. By positioning light-absorbing layers strategically, the stray light that would normally cause crosstalk is instead absorbed and converted into heat, thereby eliminating the harmful effect and improving display quality without sacrificing resolution
2Object-affected harmful factors
If a light-absorbing layer is added to prevent light crosstalk, then light crosstalk is reduced, but the device structure becomes more complex
Solution Approach 1:
The light-absorbing layer is merged with existing structural elements in the display panel, such as integrating it into the substrate or combining it with other functional layers. This merging approach allows the light-absorbing function to be achieved without adding completely separate components, thereby reducing the increase in structural complexity while still effectively preventing light crosstalk
