Display Controller Self-Diagnosis for Error Risk Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses are unable to self-diagnose operation errors without user intervention, leading to downtime and inconvenience when errors occur, as they only notify users of predefined errors without providing means for immediate resolution.
Innovation Solution
A display apparatus equipped with a controller that can change setting values to detect operation errors, determine risk factors, and transmit diagnostic information to a service apparatus for error resolution, allowing for continuous operation and proactive error management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display apparatus notifies the user of error information and guides the user to take action, then the user is informed about the error, but the display apparatus cannot operate until the user analyzes and repairs the error
Solution Approach 1:
The display apparatus performs self-diagnosis by automatically analyzing error information using a processor that executes diagnostic algorithms. The system independently identifies error types, locates faulty components, and generates repair solutions without requiring user intervention for analysis, thereby eliminating downtime while keeping users informed of the error status
Solution Approach 2:
The display apparatus pre-stores multiple types of error information and corresponding diagnostic data in memory before actual errors occur. When an error happens, the processor immediately matches the error against stored patterns and executes pre-prepared diagnostic routines, enabling instant error identification and repair without waiting for user analysis
2Device complexity
If the display apparatus only notifies predefined errors by a designer, then the notification system is simple, but the apparatus cannot diagnose unknown or complex operation errors
Solution Approach 1:
The display apparatus implements a universal error notification system where the processor can handle both predefined errors stored in memory and unknown errors by analyzing error patterns against diagnostic algorithms. This multi-functional approach allows the same system to address simple predefined errors and complex unknown errors without requiring separate notification mechanisms
Solution Approach 2:
The processor continuously monitors system operation and provides feedback by comparing actual error information against stored error patterns and diagnostic criteria. This feedback mechanism enables the system to automatically adapt its diagnosis approach whether the error is predefined or unknown, expanding diagnostic capability while maintaining a unified notification interface

AI summary
A display apparatus includes a display; a content receiver configured to receive image content; a communication interface configured to communicate with a service apparatus; a storage configured to store a setting value of factor related to an operation of the content receiver, the communication interface, and the display; and a controller configured to change the setting value of factor related to the operation of at least one of the content receiver, the communication interface, and the display, and to determine whether a risk of an operation error of at least one is caused due to the changed setting value. When it is determined that there is the at least one risk of the operation error due to the changed setting value, the controller is configured to transmit information about the factor and the operation error to a service apparatus through the communication interface.
