Symmetry OSD Menu Variable Item Sizing for Selection Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of image display devices, such as televisions, face difficulties in accurately adjusting display parameters through OSD menus due to the lack of precise adjustment value indication and confusion regarding the currently selected item, as all options are displayed with the same size and without clear selection indication.
Innovation Solution
An apparatus and method for displaying and controlling a symmetry-type OSD menu, featuring 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 display the OSD menu, determines item selection, adjusts configuration values, and stores changes, allowing for variable item sizes and modes to indicate selection and adjustments.
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 other items. Specifically, the selected item is displayed at a larger size than non-selected items, creating a visual distinction that helps users easily identify the active selection without complicating the overall menu structure.
2Measurement precision
If the level meter shows only a colored portion fluctuating, then the display is simple, but the user cannot know the precise adjustment value
Solution Approach 1:
The level meter is segmented into multiple distinct visual components: a colored portion indicating the current level, numerical values showing precise adjustment amounts, and directional arrows indicating adjustment direction. This segmentation allows the system to convey precise measurement information while maintaining a relatively simple display structure.
3Ease of operation
If the OSD menu is displayed continuously, then the user can always see the menu, but the user interface becomes cluttered and harder to navigate
Solution Approach 1:
The OSD menu implements dynamic behavior by automatically closing after a predetermined period of inactivity. The menu remains displayed only when the user is actively interacting with it, and automatically disappears when no commands are received within the threshold period. This dynamic approach improves ease of operation by keeping the interface clean while maintaining accessibility when needed.

AI summary
An apparatus for displaying and controlling a symmetry-type OSD (on-screen display) 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 to output command signals for displaying and controlling function control targets in the symmetry-type OSD menu. The control unit is for outputting control signals and control data to display and control the symmetry-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.
