Sound-Based OSD Control for Electronic Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses cannot interact with or control on-screen-display (OSD) functions executed by a host, limiting user adjustments and interaction with OSD options such as brightness, contrast, and color settings.
Innovation Solution
An electronic device comprising a display module, a display controller, and a host that collects and analyzes sound signals to generate OSD patterns, allowing the host to transmit sound information to the display controller, which overwrites specific positions on the display image with OSD patterns, enabling dynamic display of OSD options like orientation, distance, and strength of sound signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional display apparatus uses physical buttons for OSD control, then user can adjust picture quality settings, but user cannot interact with or control OSD functions when connected to host
Solution Approach 1:
The patent merges the host's application execution capability with the display apparatus's OSD control function. The host collects sound signals from applications and transmits sound information to the display controller, which generates and displays OSD patterns. This combination allows the host to control OSD functions without adding physical buttons to the display apparatus.
Solution Approach 2:
The display controller is designed to perform multiple functions: it controls the display module, receives image signals from the host, and processes sound information to generate OSD patterns. This multi-functionality allows the same hardware to serve both traditional display control and new interaction modes through sound-based OSD control.
2Adaptability or versatility
If display apparatus only receives image signals from host, then device structure remains simple, but host application cannot control or interact with OSD function
Solution Approach 1:
The display controller acts as an intermediary between the host and the display module. It receives image signals from the host through an image-transmission channel, collects sound information from the host, processes this information to generate OSD patterns, and outputs the final image to the display module. This intermediary role enables bidirectional interaction without complicating the overall system architecture.
3Ease of operation
If OSD options are displayed on screen, then user can see settings options, but user cannot interact with them without physical buttons
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a sound-based interaction system. Instead of requiring physical buttons to navigate and select OSD options, the system collects sound signals from the host, analyzes sound information, and translates it into OSD control commands. This substitution eliminates the need for additional mechanical input devices while improving accessibility.

AI summary
Displaying an on-screen-display (OSD) interface in an electronic device, wherein the electronic device comprises a display module, a display controller, and a host, the display method comprising: utilizing the host to execute an application to render a display image, and to transmit the display image to the display controller through an image-transmission channel between the host and the display controller; utilizing the host to collect a sound signal generated by the application running on the host, and to analyze the sound signal to obtain sound information corresponding to the sound signal; utilizing the host to transmit the sound information to the display controller; and utilizing the display controller to generate an on-screen-display pattern corresponding to the sound information, to overwrite a specific position of the display image with the OSD pattern to generate an output image, and to transmit the output image to the display module for displaying.
