Transparent Display Panel Layout for Less Visible Non-Display Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with self-emissive pixels often have noticeable non-display areas due to the presence of metal layers, transistors, and signal lines, which detract from the aesthetic appeal and transparency.
Innovation Solution
The design incorporates non-display transmissive areas with larger areas than adjacent components, eliminating metal layers, transistors, and signal lines, and includes anti-electrostatic elements to maintain functionality while enhancing transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal layers, transistors, and signal lines are present in non-display areas, then functional integrity is maintained, but visibility and aesthetic appeal deteriorate
Solution Approach 1:
The patent extracts and removes metal layers, transistors, and signal lines from the non-display area, retaining only the necessary functional elements (scan circuit, anti-electrostatic element) while eliminating the visible components that detract from aesthetic appeal and transparency.
Solution Approach 2:
The patent applies different structural qualities to different regions: the non-display area is designed with minimal components and larger transparent areas, while the display area maintains full functionality. This local differentiation allows the non-display area to be less noticeable while preserving overall device functionality.
2Object-affected harmful factors
If non-display transmissive area area is increased, then transparency and aesthetic appeal are improved, but device complexity increases
Solution Approach 1:
The non-display area is segmented into distinct functional zones: a non-display transmissive area with larger area for transparency, a scan line area with spaced-apart lines for signal transmission, and an anti-electrostatic element area for electrostatic protection. This segmentation allows each zone to optimize its specific function while maintaining overall simplicity.
3Object-affected harmful factors
If scan lines are spaced apart, then light transmission is improved, but signal transmission capability deteriorates
Solution Approach 1:
The spaced-apart lines in the non-display area serve multiple functions: they act as both signal transmission paths and light transmission channels. The anti-electrostatic element simultaneously provides electrostatic protection and maintains the spaced-apart line configuration for optimal light transmission.

AI summary
A display device includes a display area including first to third pixels respectively emitting lights having different colors. A display transmissive area is on a side of the pixels. A first non-display area is on a first side of the display area. The first non-display area includes a scan line area including a plurality of lines extending in a first direction and spaced apart from each other in a second direction. A scan circuit is between the scan line area and the display area, and receives a signal from the lines to provide a scan signal to the display area. An anti-electrostatic element is at an outermost portion of the first non-display area. A non-display transmissive area is between the scan line area and the anti-electrostatic element to transmit light. A planar area of the non-display transmissive area is greater than a planar area of the scan circuit.
