Display Panel Support Columns for Light-Transmitting Camera Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels face issues with Newton's rings and reduced light transmittance due to the deformation of the encapsulation cover plate, which affects the display quality and screen-to-body ratio when integrating photosensitive assemblies like cameras.
Innovation Solution
The display panel incorporates grooves in the transition and light-transmitting regions to disrupt light interference, and uses annular support columns to enhance strength without compromising light transmittance, thereby preventing Newton's rings and improving the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the encapsulation cover plate is made thin to increase screen-to-body ratio, then the screen ratio is improved, but the plate deforms causing Newton's rings and reduced light transmittance
Solution Approach 1:
The patent applies local quality by providing support columns at specific locations (corners and edges) of the encapsulation cover plate rather than uniform support across the entire plate. This localized support structure prevents deformation and Newton's rings in critical areas while maintaining the overall thin profile and high screen-to-body ratio of the display panel.
Solution Approach 2:
The patent uses composite materials by combining the encapsulation cover plate with support columns made of different materials having complementary properties. The cover plate material (e.g., glass or plastic) provides optical clarity and thinness, while the support column material provides structural strength and rigidity, creating a composite structure that achieves both high screen ratio and sufficient strength.
2Strength
If support columns are added to enhance encapsulation cover plate strength, then the plate deformation is reduced, but the light transmittance is blocked
Solution Approach 1:
The patent applies segmentation by dividing the support function into multiple discrete support columns rather than using a continuous support structure. These segmented support columns are strategically positioned at corners and edges where structural support is most needed, minimizing their interference with the light transmission area while collectively providing sufficient support to prevent plate deformation and Newton's rings.
Solution Approach 2:
The patent extracts the support function from the main encapsulation cover plate body by using separate, independent support columns. This extraction allows the cover plate to maintain its optical properties and thinness for high light transmittance, while the extracted support columns provide the necessary structural strength without compromising the optical performance of the main plate.
3Object-affected harmful factors
If grooves are added to prevent Newton's rings, then the light interference is disrupted, but the structural strength is reduced
Solution Approach 1:
The patent applies local quality by providing grooves with specific depth characteristics in different regions of the encapsulation cover plate. The grooves are designed with controlled depth parameters that are sufficient to disrupt light interference and prevent Newton's rings, while maintaining adequate structural strength in critical load-bearing areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents Newton's rings and enhances light transmittance, allowing for full-screen integration of photosensitive assemblies while maintaining structural integrity and increasing the screen-to-body ratio.
Implementation Method 1
the groove provided in the encapsulation cover plate or the display base plate can destroy the mutual interference condition of lights at both ends of the bathtub curve, thereby fundamentally avoiding the Newton's ring phenomenon
