Solution Overview
Problem
Conventional display panels face challenges in integrating additional functions within a limited display area while maintaining image display capabilities, particularly in achieving optimal light transmission and resolution across different display regions.
Innovation Solution
The display panel incorporates a structure with multiple light-emitting diodes of varying colors arranged in distinct display areas, including a transmissive area, where the second display area has a greater emission area width for light-emitting diodes of a specific color and fewer diodes per area, connected through conductive bus lines with transparent materials to enhance light transmission and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area is increased to add various functions, then the functionality is improved, but the area occupied by the display area increases
Solution Approach 1:
The display panel is designed to perform multiple functions within the same display area. The transmissive area allows the display panel to function both as a display device and as a window or sensor integration area, enabling additional functions without increasing the overall area occupied by the display panel.
Solution Approach 2:
The display area is divided into different regions with different properties: a first display area for normal display and a transmissive area for light transmission. This local differentiation allows different parts of the display panel to serve different functions, with the transmissive area enabling additional functionalities while the first display area maintains image display capabilities.
2Illumination intensity
If the emission area width of light-emitting diodes is increased to improve light transmission, then the light transmission is improved, but the resolution is degraded
Solution Approach 1:
Different regions of the display panel have different light-emitting diode configurations. In the transmissive area, light-emitting diodes have a greater emission area width to maximize light transmission. In the first display area, light-emitting diodes have a smaller emission area width to maintain high resolution for image display. This local optimization allows each region to achieve its primary function without compromising the other.
