External Display Blank-Region Content Control for Aspect Ratio Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively utilize the blank regions on external displays due to aspect ratio mismatches between the image and the display, leading to potential misoperations by users.
Innovation Solution
A control device generates extended information to create extended content that is displayed in the blank regions of an external display, utilizing the first and second processing units to transmit and display this content alongside the main image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image is transmitted with the original aspect ratio to the external device, then the image quality is preserved, but a blank area is generated on the external display where the image is not displayed
Solution Approach 1:
The display area is segmented into multiple regions: a first region for displaying the transmitted image and a second region (blank area) for displaying extended content. This segmentation allows the image to maintain its original aspect ratio while utilizing the previously wasted blank space for additional functional content.
Solution Approach 2:
The blank area, which originally served no functional purpose, is transformed into a multi-functional region that can display extended content such as notifications, controls, or additional information, thereby giving it universal utility across different display scenarios.
2Manufacturing precision
If the blank space is left unused, then the image aspect ratio is maintained, but user operations on the blank space may cause misoperations between the external device and the control device
Solution Approach 1:
The blank area, which causes potential misoperations when left empty, is converted into a beneficial region by filling it with extended content that provides clear visual feedback and defined interaction areas, thereby eliminating the ambiguity that led to misoperations.
3Area of stationary object
If extended content is displayed in the blank region, then the blank region is effectively utilized, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The control device acts as an intermediary that generates extended information based on the transmitted image and sends it to the external device. This intermediary approach allows the external device to display extended content without requiring complex local processing, thereby distributing the computational burden.
Solution Approach 2:
The system changes the parameter of content delivery by transmitting not only image data but also associated extended information that describes what to display in the blank region. This parameter change enables the external device to simply render the provided content without performing complex analysis or generation tasks.

AI summary
A first processing unit in a control device generates extended information and transmits to the external device extended information that can generate image information and extended content related to an image displayed on an external display (for example, a display of an external device), or extended content and image information based on the extended information. A second processing unit in the external device displays the image and extended content on an external display. Extended content is displayed in a blank region on the external display (i.e., an area other than the area where images are displayed on the external display).
