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

VSEngineering 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

Engineering Contradiction:
ImproveOSD interaction capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveapplication control capabilityVSAvoidsignal processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
ImproveOSD accessibilityVSAvoidinput mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
