Solution Overview

Problem

Conventional display apparatuses for vehicles often fail to adaptively adjust display arrangements when a driver malfunctions, leading to abnormal display pictures that can distract drivers and pose safety risks due to serially connected source and gate drivers, where a single failure can result in entire display failure.

Innovation Solution

A display apparatus and computer system that includes a display panel coupled with multiple gate and source drivers, where functioning drivers transform and transmit display information to maintain a stable display, even if one driver fails, by setting up a master and slave unit configuration for two-way communication and adaptive scaling to prevent abnormal display occurrences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If serially connected source drivers and gate drivers are used in the display apparatus, then the device complexity is reduced and manufacturing is simplified, but the reliability deteriorates because a single driver failure causes entire display failure

Engineering Contradiction:
Improvedriver configuration complexityVSAvoiddisplay continuity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the display panel into multiple independent display zones, each controlled by its own driver unit. When a driver fails, only the corresponding display zone is affected while other zones continue to function normally. This segmentation isolates failures and prevents system-wide downtime, resolving the reliability issue while maintaining relatively simple driver architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic display information transformation that adapts based on driver operational status. When a driver is detected as abnormal, the system dynamically adjusts the display arrangement and transforms display information to accommodate the failed driver, ensuring continuous display functionality. This dynamic adaptation resolves the contradiction between simple fixed architecture and reliable adaptive operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If adaptive display transformation is implemented to handle driver failures, then the reliability improves by maintaining display functionality, but the device complexity increases due to additional processing requirements

Engineering Contradiction:
Improvedisplay functionalityVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent pre-establishes multiple display arrangement patterns and transformation rules before driver failure occurs. When a driver fails, the system simply switches to the pre-configured appropriate pattern rather than performing complex real-time calculations. This preliminary preparation maintains high reliability while minimizing the processing complexity during actual failure scenarios.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates transformed copies of display information that can be displayed through alternative driver paths when the original driver fails. Instead of complex reconstruction, the system generates simplified copy versions of the display content that can be rendered by remaining functional drivers, maintaining display continuity with minimal processing overhead.

Inventive Principle:
Principle #26Copying

3Reliability

If the display apparatus continuously monitors driver status to detect failures, then the reliability improves through early failure detection, but the use of energy increases due to continuous monitoring operations

Engineering Contradiction:
Improvefailure detection capabilityVSAvoidmonitoring energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic sampling of driver status rather than continuous monitoring. The system checks driver health at predetermined intervals or triggered by specific events, skipping continuous verification between samples. This approach maintains adequate failure detection capability while significantly reducing energy consumption compared to continuous monitoring, resolving the contradiction between reliability and energy use.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

A display apparatus for displaying a display information includes a display panel, and a plurality of gate drivers and a plurality of source drivers coupled to the display panel. When one abnormal driver exists among the plurality of gate drivers and the plurality of source drivers, the other functionally operating gate drivers and source drivers transform the display information into a transformed display information to transmit the transformed display information to the display panel for a display operation.
