Floating Touch Display Interval Layer Optical Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floating touch display devices often result in out-of-focus floating images due to the lack of an interval layer between the optical unit and the imaging unit, which affects the object distance and clarity of the floating image.
Innovation Solution
Incorporating an interval layer between the optical lens structure and the display device, and optionally between the capacitive touch panel and the optical lens structure, to adjust and equalize the first and second optical distances, ensuring that the floating image is clearly projected at the same height and size as the display image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If no interval layer is disposed between the optical unit and the imaging unit, then the device structure is simpler, but the floating image becomes out of focus and clarity deteriorates
Solution Approach 1:
An interval layer is introduced as an intermediary component between the optical unit and the imaging unit. This interval layer serves as a mediator to adjust the optical path and ensure proper focusing of the floating image, resolving the contradiction by adding a simple structural element that significantly improves image clarity without substantially complicating the overall device structure.
2Manufacturing precision
If the object distance of the imaging unit is not adjusted properly, then the device structure is simpler, but the floating image quality deteriorates
Solution Approach 1:
The interval layer is used to adjust the object distance parameter of the imaging unit. By changing the spatial parameter (distance) through the introduction of the interval layer, the floating image quality is optimized. This approach allows for precise control of the optical path without requiring complex adjustment mechanisms, maintaining structural simplicity while improving image quality.
3Manufacturing precision
If the first optical distance is not equal to the second optical distance, then the device structure is simpler, but the floating performance and image clarity deteriorate
Solution Approach 1:
The interval layer acts as a mediator to balance and equalize the first optical distance and the second optical distance. By introducing this intermediate structural element, the optical path lengths are properly controlled to be equal, ensuring both floating performance and image clarity are optimized without requiring complex optical distance control mechanisms.
