Display Pixel Patterning for Camera Clarity and Transmissive Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maximizing the transmissive area and maintaining image clarity and readability, particularly when used with camera systems, due to the arrangement of unit pixels and transmissive areas that can lead to reduced image recognition rates and haze phenomena.
Innovation Solution
The display device arranges unit pixels in a row and column direction with varying patterns, creating larger transmissive areas and distributing sub-pixels to minimize contact between same-colored pixels, enhancing image recognition and reducing haze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If unit pixels are arranged in a conventional uniform pattern, then manufacturing is simple, but the transmissive area is reduced and image clarity deteriorates
Solution Approach 1:
The display panel is divided into multiple unit pixels, each containing a plurality of sub-pixels (red, green, blue, white). This segmentation allows for optimized arrangement patterns within each unit pixel while maintaining overall simplicity. The unit pixels are further segmented into different pattern types (first, second, third, fourth patterns) that can be alternately disposed to maximize transmissive area.
Solution Approach 2:
Different unit pixels are designed with different arrangement patterns (first pattern, second pattern, third pattern, fourth pattern) rather than using a uniform pattern throughout. These asymmetric patterns are alternately disposed in the row and column directions, creating an optimized layout that increases transmissive area while maintaining manufacturing feasibility through systematic variation.
2Manufacturing precision
If sub-pixels of the same color are placed adjacent to each other, then manufacturing is easier, but image clarity and readability deteriorate due to pixel boundaries
Solution Approach 1:
Within each unit pixel, sub-pixels of different colors (red, green, blue, white) are strategically arranged so that same-colored sub-pixels do not contact each other between adjacent unit pixels. This local optimization of sub-pixel arrangement prevents color bleeding and maintains image clarity while remaining compatible with standard manufacturing processes.
3Measurement precision
If transmissive areas are increased for camera functionality, then camera image recognition improves, but display area is reduced
Solution Approach 1:
The patent optimizes the arrangement of unit pixels in both row and column directions using multiple patterns (first, second, third, fourth patterns) to create transmissive areas that form zigzag patterns. This multi-dimensional optimization allows transmissive areas to be strategically positioned for camera functionality while maximizing the remaining display area through efficient spatial arrangement.
