Display Device Segmented Settings for Edge Blending Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-screen projection techniques, such as edge blending, often reduce the visibility of on-screen display (OSD) screens by overlapping them with edge blending areas, limiting configurability and image adjustment ranges, which affects usability and visibility.
Innovation Solution
A display device and method that allow for wider settings ranges on a second settings screen compared to a first settings screen, enabling more flexible image adjustments while displaying a warning if settings exceed the first screen's ranges, thereby maintaining visibility and configurability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If edge blending is applied to make image joints less distracting, then image quality is improved, but OSD screen visibility decreases in overlapping areas
Solution Approach 1:
The settings screens are segmented into two distinct types: a first settings screen displayed within the projected image that accepts settings within a first range, and a second settings screen displayed on the external device that accepts settings within a second range wider than the first range. This segmentation allows different settings to be configured in different locations, resolving the conflict between edge blending and OSD visibility.
Solution Approach 2:
The external device acts as an intermediary for configuring certain settings. By displaying the second settings screen on the external device rather than within the projected image, the system allows access to wider setting ranges without compromising the visibility of the projected OSD screen in edge blending areas.
2Object-affected harmful factors
If the display area of the OSD screen is moved to avoid overlap with edge blending area, then OSD visibility is improved, but configurability of the edge blending area decreases
Solution Approach 1:
The solution moves the settings interface from a two-dimensional constraint within the projected image to a third-dimensional solution by utilizing the external device's display. This allows the second settings screen to provide access to wider setting ranges without occupying the same visual space as the projected image, thereby maintaining both OSD visibility and configurability.
3Ease of operation
If image adjustment ranges are limited to maintain OSD visibility, then OSD usability is improved, but freedom in adjusting projected images decreases
Solution Approach 1:
The settings functionality is segmented between two screens with different capability levels. The first settings screen provides limited settings within a first range that maintains OSD usability, while the second settings screen on the external device provides extended settings within a second range that offers greater freedom in adjusting projected images without compromising the first screen's usability.
Data Source
AI summary
A display device receives, from an external device, information set on a settings screen that is displayed on the external device and that allows settings in ranges wider than ranges settable on a settings screen constituting a part of a projected image. The display device then changes settings in accordance with the received information. As a result, a degree of freedom in adjustment of the projected image can be increased.
