Display Light-Shielding Patterns for High-Resolution Color Purity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current display devices, increased resolution leads to light with a large angle passing through unexpected light filtering layers, causing color mixing issues.
Innovation Solution
The electronic device incorporates a first light shielding layer with specific light shielding patterns and openings, along with a light converting layer, to reduce color mixing by strategically arranging light shielding layers between substrates and display medium layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display device is increased, then the display quality is improved, but light with a large angle passes through unexpected light filtering layers causing color mixing
Solution Approach 1:
The light shielding layer is divided into multiple light shielding patterns (first light shielding pattern and second light shielding pattern) arranged in specific configurations. This segmentation creates multiple zones for light management, allowing the device to block oblique light effectively while maintaining high resolution display quality.
Solution Approach 2:
Different regions of the light shielding layer are designed with different properties - the light shielding patterns provide light blocking functionality while the openings between them allow light transmission. This local differentiation enables selective light management: blocking oblique light that causes color mixing while permitting necessary light for display.
2Object-affected harmful factors
If light shielding patterns are added to reduce color mixing, then color mixing is reduced, but the device structure becomes more complex
Solution Approach 1:
The light shielding layer is integrated with the existing display structure, combining light shielding functionality with the overall device architecture. The light shielding patterns are formed as part of the layered structure between substrates, merging multiple functions into a unified design rather than adding separate components.
Solution Approach 2:
The light shielding layer serves multiple functions simultaneously: it blocks oblique light to prevent color mixing, maintains structural integrity of the display device, and works in conjunction with the light converting layer to ensure proper light transmission for display purposes.

AI summary
An electronic device includes a first substrate, a second substrate, a display medium layer, a circuit layer, a first light shielding layer, and a light converting layer. In a cross-sectional view of the electronic device, the first light shielding layer includes a first light shielding pattern and a second light shielding pattern adjacent to the first light shielding pattern, the first light shielding pattern and the second light shielding pattern are arranged along a direction, and an opening is included between the first light shielding pattern and the second light shielding pattern along the direction. The light converting layer is overlapped with the opening. The first light shielding pattern has a first width along the direction, the opening has a second width along the direction, and a ratio of the first width to the second width ranges from 0.5 to 2.
