OSD Input Device Signal Routing for Display OS Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices lack a seamless method to interact with their OS system without requiring additional external devices like keyboards, mice, or mobile apps, leading to inefficiencies and increased costs.
Innovation Solution
A display device control method that utilizes an OSD input device to control both the OSD and OS systems, switching signals between the two systems based on user operations and timeouts, eliminating the need for external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile phone or remote control is used to control the OS system of the display device, then the OS system can be operated, but additional external devices and apps are required, increasing device complexity and operational difficulty
Solution Approach 1:
The OSD input device is designed to perform multiple functions: it can control both the OSD system and the OS system. By making the input device universal, the patent eliminates the need for separate external control devices like mobile phones or remote controls, thereby reducing device complexity while maintaining ease of operation
Solution Approach 2:
The display device uses its own built-in OSD input device to control its own OS system, rather than requiring external devices. This self-service approach eliminates dependency on external controllers and apps, simplifying the overall system while improving operational convenience
2Ease of operation
If a mobile phone with an app is used to control the OS system, then the OS system can be operated, but the operational process becomes complex requiring search and pairing operations
Solution Approach 1:
The display device utilizes its own built-in OSD input device for controlling the OS system, eliminating the need to search for, install, and pair external mobile apps. This self-service mechanism immediately provides control capability without time-consuming setup procedures
Solution Approach 2:
The OSD input device is pre-configured and built into the display device, with signal routing capabilities established in advance. This preliminary setup eliminates the need for runtime pairing and configuration operations that would otherwise consume user time
3Ease of operation
If a remote control is used to control the OS system, then the OS system can be operated, but the remote control cost increases and may be lost when separated from the display device
Solution Approach 1:
The OSD input device is designed to control both OSD and OS systems, eliminating the need for a separate remote control. This multi-functional design reduces hardware quantity and associated costs while maintaining operational capability
Solution Approach 2:
The control functions for both OSD and OS systems are merged into a single built-in input device, eliminating the need for separate external controllers. This consolidation reduces hardware costs and prevents loss by integrating the control function into the display device itself

AI summary
A display device control method includes when an operation on an on-screen display (OSD) input device is received, determining whether a signal generated by operating the OSD input device is currently sent to an OSD system or an operating system (OS); and when the signal generated by operating the OSD input device is currently sent to the OS, switching, according to a control signal generated by the OSD input device, the control signal from being sent to the OSD system to being sent to the OS. This application further provides a display device.
