Solution Overview
Problem
Existing display panels face challenges in implementing a full-screen display due to the presence of camera modules, which restrict screen size and require increased transmittance to improve image quality, but are hindered by pixel circuits and lines.
Innovation Solution
A display panel design with distinct regions of varying pixel densities, including a second region with light transmitting parts arranged in a zigzag pattern to accommodate sensor modules, enhancing transmittance and reducing flare phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera module is disposed to overlap the screen to implement full-screen display, then screen size is increased, but transmittance of the display panel decreases due to pixel circuits and lines
Solution Approach 1:
The display panel is divided into two distinct regions: a first region with normal pixel density for display purposes, and a second region with reduced pixel density and increased light transmitting parts for camera sensing. This segmentation allows different areas to serve different functions, enabling full-screen display while maintaining high transmittance in the camera region.
Solution Approach 2:
Different regions of the display panel are given different optical properties. The second region specifically designed for camera overlap has a higher proportion of light transmitting parts and fewer pixel circuits, creating local optimization for light transmission without compromising the overall display quality in the first region.
2Measurement precision
If transmittance is increased to improve image quality, then image quality improves, but display quality deteriorates due to reduced pixel density
Solution Approach 1:
The panel is segmented into a first region for high-quality display and a second region for camera sensing. This allows the second region to have optimized light transmission properties without affecting the display quality in the first region, as they serve different functional purposes.
Solution Approach 2:
The second region is locally optimized with increased light transmitting parts and reduced pixel density specifically for camera function, while the first region maintains normal pixel density for display quality. This local differentiation resolves the contradiction between image quality and display quality.
3Ease of manufacture
If light transmitting parts are arranged in regular pattern, then manufacturing is simplified, but flare phenomena and lattice patterns increase
Solution Approach 1:
The light transmitting parts in the second region are arranged in an asymmetric zigzag pattern rather than a regular grid. This asymmetric arrangement disrupts the formation of lattice patterns and flare phenomena while still maintaining manufacturability through systematic placement.
Solution Approach 2:
The light transmitting parts are designed with circular or oval shapes instead of angular forms. This curved geometry helps minimize flare phenomena and lattice patterns by distributing light transmission more uniformly, while the zigzag arrangement of these circular/oval parts maintains ease of manufacture.
