Asymmetric Viewing Angles for Dual-View Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-view displays with symmetrical viewing angles can pose safety hazards in applications like motor cars, where driver and passenger viewing zones are identical, potentially leading to accidental crossover of viewing areas.
Innovation Solution
Introducing multiple sub-pixel pitches on a single display panel to create asymmetric viewing angles without affecting the outer viewing angles or boundaries, allowing for distinct angular extends for different viewing windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If symmetrical viewing angles are used in dual-view displays, then the display structure is simple and manufacturing is easier, but safety is compromised in applications like motor cars where driver and passenger viewing zones may accidentally crossover
Solution Approach 1:
The patent applies asymmetry by configuring the barrier at an angle relative to the display panel, creating asymmetric viewing angles for different viewing zones. This asymmetric barrier configuration ensures that the driver's viewing zone and passenger's viewing zone do not overlap, thereby improving safety while maintaining a relatively simple display structure without requiring multiple display panels or complex additional components
2Reliability
If asymmetric viewing angles are implemented using conventional barrier configurations, then safety is improved by separating viewing zones, but the outer viewing angles or boundaries of the viewing windows are affected
Solution Approach 1:
The patent applies local quality by making the barrier asymmetric only in the regions where viewing zone separation is needed, while maintaining symmetric outer boundaries of the viewing windows. The barrier is configured with different angular configurations for different local regions, ensuring that the driver and passenger viewing zones are separated while the overall viewing window boundaries remain symmetric and unaffected

AI summary
The present invention is related to an asymmetric aligned display having asymmetric viewing angles. The present invention provides a dual-view or 3D display capable of displaying two images of unrelated or related content along different directions with asymmetric viewing angles. The asymmetric viewing angles of the display device of the present invention can be realized by the introduction of multiple sub-pixel pitches into a single display. To be more specific, the present invention provides an asymmetric aligned display by realizing the asymmetry design in the sub-pixel itself. Consequently, the angular extends of the respective viewing windows or images displayed along different directions can be different or asymmetrical. The asymmetric aligned display of the present invention is, therefore, capable of displaying images along different directions with asymmetric viewing angles and windows without affecting the outer boundaries of the viewing windows.
