Annularity OSD Menu Size Variation for Selection Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of image display devices face difficulties in accurately adjusting display parameters through OSD menus due to the lack of precise adjustment values and confusion regarding the currently selected item, as all options are displayed with the same size and without clear indication of selection.
Innovation Solution
An apparatus and method for displaying an annularity-type OSD menu that includes a key input unit, control unit, OSD menu generation unit, storage unit, image signal output unit, pre-amplifier, and image display device, which outputs command signals to control and display the OSD menu, allowing for variable size and mode changes of function control targets based on user input, enabling clear selection and adjustment of parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all optional items are displayed with the same size in the OSD menu, then the menu layout is simple and uniform, but the user cannot easily identify which item is currently selected
Solution Approach 1:
The patent applies local quality by making the currently selected optional item differ in size from the other items. Specifically, the selected item is displayed in a larger size while non-selected items remain in a smaller, uniform size. This size differentiation locally modifies the display property of the selected item to improve user identification without fundamentally changing the overall menu structure.
2Measurement precision
If the level meter shows only a colored portion without exact values, then the display is simple, but the user cannot know the precise adjustment values
Solution Approach 1:
The patent merges two display elements into a single integrated level meter: the colored portion indicating current level and the numerical value showing exact adjustment. Instead of separating these functions into different components, the invention combines them into one unified display element that simultaneously provides both visual (colored bar) and numerical (exact value) feedback, thereby improving measurement precision without significantly increasing device complexity.
3Ease of operation
If the OSD menu remains displayed indefinitely, then the user has time to make adjustments, but the screen is occupied and cannot display other content
Solution Approach 1:
The patent implements periodic action by setting the OSD menu to be automatically closed after a predetermined period of time if no adjustment operations are detected. The menu remains open during this period to allow user adjustments, but then periodically closes to free up the screen for other content. This creates a time-based cycle of menu display and closure that balances adjustment time needs with screen availability.

AI summary
An apparatus for displaying and controlling an annularity-type OSD menu in an image display device includes a key input unit (10), a control unit (11), an OSD menu generation unit (12), a storage unit (13), an image signal output unit (14), a pre-amplifier (15), an image output unit (16), and an image display device (17). The key input unit is for pressing or rotating to output command signals for displaying and controlling function control targets in the annularity-type OSD menu. The control unit is for outputting control signals and control data to display and control the annularity-type OSD menu according to the command signals. Each function control target includes related optional items, and can be expanded into its related optional items at an active area of the image display device. Further, each function control target can be displayed in a different size according to its display position.
