Display Opening Ring Pattern with Variable Heights for Flare Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in display area in electronic devices leads to issues with camera and sensor modules being affected by light from the display, causing flare phenomena and reducing image quality, and the printed patterns on the display cause flatness and deformation issues.
Innovation Solution
A ring-shaped printed pattern is disposed on the top or bottom surface of specific layers in the display, with varying heights to prevent light interference and maintain flatness, improving image quality and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a printed pattern is disposed on the display to block light and prevent flare, then light blocking effectiveness is improved, but flatness of the display deteriorates due to steps and deformation
Solution Approach 1:
The printed pattern is designed with varying heights (first height and second height) to create different local properties. The first portion has a first height and the second portion has a second height different from the first height, allowing each portion to optimally address light blocking while minimizing overall impact on display flatness.
Solution Approach 2:
The printed pattern transitions from a two-dimensional flat structure to a three-dimensional structure with varying heights. By introducing height variation as an additional dimension, the pattern can block light more effectively while the lower portions maintain better contact with underlying layers, reducing deformation and preserving flatness.
2Ease of operation
If the display area is increased to improve visibility and operation convenience, then user convenience is improved, but camera and sensor modules are affected by display light causing flare phenomena
Solution Approach 1:
The printed pattern is positioned specifically around the opening area where the camera and sensor modules are located, rather than across the entire display. This localized approach blocks light only where needed to prevent flare, while allowing the rest of the display to maintain its light-emitting function for visibility and operation.
Solution Approach 2:
The printed pattern acts as an intermediary structure between the display and the camera/sensor modules. It selectively blocks light paths that would cause flare while allowing necessary light transmission for display visibility, mediating between these conflicting requirements.
3Object-affected harmful factors
If a printed pattern is disposed on the display to block light, then light blocking is improved, but image quality deteriorates due to local deformation and adhesive deformation
Solution Approach 1:
The printed pattern uses different heights in different portions to locally optimize performance. The first portion with the first height and the second portion with the second height create varying degrees of light blocking and structural support, preventing uniform deformation that would degrade image quality while maintaining effective light blocking where critical.
Solution Approach 2:
The varying heights of the printed pattern provide preemptive structural support to compensate for potential deformation. The higher portions provide additional support before deformation can occur, cushioning against the harmful effects of light blocking structures on image quality.
