Custom Label Display for External Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices, such as digital TVs, struggle to allow users to easily recognize information about connected external devices, as the on-screen display (OSD) often uses generic labels like AV1 or HDMI, which are not intuitive for general users.
Innovation Solution
An image display device that allows users to set and display custom labels for external devices using images and text, enabling easy recognition of the device type and information through a user-input unit, memory unit, and controller, which captures and outputs the label on the display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If generic labels like AV1 or HDMI are used in the OSD, then the device complexity is reduced and manufacturing is simplified, but the ease of operation deteriorates because users cannot easily recognize external device information
Solution Approach 1:
The system automatically captures an image of the external device during the connection setup phase before the user needs to identify it. This preliminary action stores visual information that will be displayed later as a label, eliminating the need for users to manually input device information and solving the recognition problem without adding complex ongoing operations
Solution Approach 2:
Instead of using generic text labels, the system creates and displays a visual copy (image) of the external device as its label. This copied visual representation is stored in memory and displayed on the screen, making device identification intuitive and immediate without requiring users to interpret technical connection names
2Ease of operation
If custom labels with images and text are implemented for external devices, then the ease of operation improves by enabling easy recognition, but the device complexity increases due to additional components for capturing and storing labels
Solution Approach 1:
The controller performs multiple functions: it manages the external device connection, captures the device image, stores the label in memory, and displays it on the screen. By making the controller multi-functional, the patent avoids adding separate dedicated components for each function, thus improving ease of operation while minimizing the increase in device complexity
Solution Approach 2:
The system merges the label management functionality into the existing display system. The same display unit that shows video content also displays the external device labels, and the same controller that manages video signals also manages label capture and storage. This merging approach allows custom labels to be implemented without adding separate dedicated hardware components
