Innovation Solution
A display panel configuration featuring a first and second display area with light-emitting diodes, pixel circuits, a pixel-defining layer, and an antireflection layer, including a light-shielding layer and color filters, where hole regions between the diodes allow for component integration without compromising pixel circuit placement, enabling identical resolution and enhanced transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If circuit devices and wires are arranged in the second display area to enable diverse functionalities, then adaptability is improved, but light transmittance deteriorates due to blocking of light paths
Solution Approach 1:
The second display area is segmented into functional regions (where circuit devices are located) and hole regions (where light should pass through). By dividing the display area into these distinct zones, the patent enables circuit devices to be placed in specific regions without blocking light paths in the hole regions, thus maintaining both functional diversity and light transmittance.
Solution Approach 2:
Different regions of the second display area are assigned different properties: some regions contain circuit devices for functionality, while hole regions are designed with openings in the pixel-defining layer and light-shielding layer to maximize light transmittance. This local differentiation allows each region to optimize for its specific purpose.
2Manufacturing precision
If the pixel-defining layer and light-shielding layer are made continuous to improve manufacturing precision, then manufacturing precision is improved, but light transmittance in hole regions deteriorates
Solution Approach 1:
The pixel-defining layer and light-shielding layer are segmented with controlled openings in the hole regions. These openings are strategically placed to allow light transmission while maintaining the overall structural integrity and continuity of the layers in other regions, thus balancing manufacturing precision with light transmittance.
Solution Approach 2:
The pixel-defining layer and light-shielding layer exhibit local quality variations: they are continuous in regions requiring structural stability and manufacturing precision, but contain localized openings in hole regions to permit light transmission. This spatially varying structure resolves the contradiction between layer continuity and light transmittance.
3Weight of moving object
If the display panel is thinned to reduce weight and thickness, then weight and thickness are reduced, but structural strength deteriorates
Solution Approach 1:
The display panel employs a composite multi-layer structure including substrate, pixel-defining layer, light-shielding layer, and display elements. This composite construction allows the panel to achieve reduced thickness and weight while maintaining structural strength through the synergistic combination of multiple thin layers, each contributing to overall integrity.
Solution Approach 2:
The panel structure is segmented into multiple thin functional layers rather than a single thick layer. This segmentation enables weight reduction while each layer is optimized for its specific function, and the cumulative effect of multiple bonded layers maintains structural strength despite reduced individual layer thickness.
