Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current active-matrix organic light emitting diode display panels face challenges in improving the light transmittance rate of their transparent display zones, which affects the photographing effect of under-display cameras.
Innovation Solution
The display panel design includes a transparent display zone with pixel driving circuit islands positioned on its periphery, each containing multiple first pixel driving circuits that drive the display pixels, thereby avoiding any driving circuits on the transparent zone and enhancing light transmittance by increasing the dimension of the light transmissive zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If pixel driving circuits are disposed within the transparent display zone, then the display functionality is maintained, but the light transmittance rate of the transparent display zone deteriorates
Solution Approach 1:
The pixel driving circuits are segmented and concentrated into discrete island regions positioned at the periphery of the transparent display zone, rather than being distributed throughout the transparent area. This segmentation allows the transparent zone to remain clear while the driving functions are preserved in the peripheral islands.
Solution Approach 2:
The driving circuit layout transitions from a two-dimensional distribution within the transparent zone to a one-dimensional arrangement along the periphery edge. This dimensional change moves the driving circuits out of the light transmission path while maintaining their functional connectivity to the display pixels.
2Illumination intensity
If the transparent display zone area is increased, then the light transmittance rate is improved, but the space for disposing driving circuits deteriorates
Solution Approach 1:
The driving circuits are segmented into compact island groups positioned at the periphery, allowing the central transparent display zone to maximize its area for light transmission while the segmented islands efficiently utilize the peripheral space for driving functions.
Solution Approach 2:
The driving circuit space is relocated from the two-dimensional plane of the display zone to the one-dimensional periphery edge, effectively increasing the available area for the transparent display zone while maintaining sufficient space for driving circuits along the boundary.
3Ease of operation
If pixel driving circuits are disposed on the transparent display zone, then the display functionality is ensured, but the photographing effect of under-display camera deteriorates
Solution Approach 1:
The pixel driving circuits are extracted from the transparent display zone and relocated to peripheral island regions. This extraction removes the harmful factor (driving circuits) from the light transmission path, thereby improving the photographing effect of the under-display camera while maintaining display functionality through the peripheral driving arrangement.
Solution Approach 2:
The driving circuits are moved from the central display area to the periphery edge, effectively separating the driving function from the light transmission path. This dimensional relocation eliminates the interference with camera photography while preserving the display operational capability.
