Panel Driving Circuit Error Icon Overlay for Automotive Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a unified transmission protocol between automotive systems and display panels in vehicles hinders error detection and debugging during the manufacturing process, prolonging the time required to identify and address malfunctions in display panels.
Innovation Solution
A panel driving circuit is introduced that receives frames from the automotive system, determines if a panel error occurs, and replaces a portion of the frame with an error icon to generate a prompt frame, which is then transmitted to the display panel, allowing for error detection and communication of issues without a pre-established protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unified transmission protocol is implemented between automotive system and display panel, then error detection capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary layer (panel driving circuit with error detection module) between the automotive system and display panel. This intermediary actively monitors transmission data, detects errors, and generates error icons without requiring a complex unified protocol. The intermediary handles error detection autonomously, maintaining simplicity while improving reliability.
Solution Approach 2:
The panel driving circuit performs self-diagnosis by autonomously detecting transmission errors and generating error icons. The system serves itself by having the display panel independently monitor its own reception status and visually indicate errors through on-screen display, eliminating the need for external protocol complexity.
2Loss of time
If active error monitoring and icon replacement is implemented, then debugging time is reduced, but device complexity increases
Solution Approach 1:
The panel driving circuit pre-stores multiple error icons corresponding to different error types before actual errors occur. When an error is detected, the appropriate icon is immediately retrieved and displayed without requiring real-time analysis or external intervention, significantly reducing debugging time while keeping the added complexity manageable.
Solution Approach 2:
The error detection system uses visual color-coded icons to represent different error types. This allows rapid identification of error nature at a glance during debugging, reducing the time needed to diagnose issues. The color-based visual feedback system provides intuitive error communication without complex data exchange protocols.

AI summary
The display system includes an automotive system (130), a display panel (110), and a panel driving circuit (120). The panel driving circuit (120) receives a frame from the automotive system (130) and determines if a panel error with respect to the display panel (110) occurs. If the panel error occurs, the panel driving circuit (120) replaces a portion of the frame with an error icon to generate a prompt frame, and transmit the prompt frame to the display panel (110). If the panel error does not occur, the panel driving circuit (120) transmits the frame to the display panel (110).
