Solution Overview

Problem

Current display technologies face challenges such as the inability to dynamically update and modify the physical active region of the display panel, leading to inefficiencies in power consumption and user experience.

Innovation Solution

The system allows for dynamic reconfiguration of the active display region by determining a subset active region of the original active region and generating a hint to configure additional displays for the subset active region, optimizing power usage and user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the full active region is used for displaying images, then the display can show complete content, but power consumption increases unnecessarily when the full region is not required

Engineering Contradiction:

Improvepower consumptionVSAvoiddisplay region flexibility

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic reconfiguration of the display active region by introducing a display reconfiguration layer that can modify the active region size and position in real-time based on content requirements. This allows the display to transition from a static fixed active region to a dynamic adjustable one, enabling power savings when full region is not needed while maintaining adaptability for different display scenarios.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters of the display active region (size, position, shape) by injecting modified display data through the display reconfiguration layer. This layer alters the display data stream to reflect the new active region parameters, allowing the display panel to render images only in the necessary portion while saving power, and can be adjusted based on content type and user preferences.

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If all data for the full active region is encrypted for DRM content, then security is maintained, but power consumption increases due to encrypting and decrypting unnecessary data

Engineering Contradiction:

Improvepower consumptionVSAvoidDRM security

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent extracts only the necessary portion of encrypted display data corresponding to the reduced active region. By applying the active region modification before or during the decryption process, the system decrypts only the required data subset rather than the entire full-resolution encrypted stream, reducing computational power consumption while maintaining DRM security for the displayed content.

Inventive Principle:

Principle #2Taking out (Extraction)

3Use of energy by moving object

If the active region is dynamically updated, then power savings and user preferences can be accommodated, but flicker occurs due to synchronization issues

Engineering Contradiction:

Improvepower consumptionVSAvoiddisplay stability

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent applies display reconfiguration at the earliest possible stage in the display pipeline, modifying the active region parameters before the display data is fully processed and sent to the panel. By establishing the new active region configuration in advance and maintaining it consistently across all subsequent processing stages, the system avoids mid-frame or mid-refresh reconfiguration that would cause visible flicker, thus maintaining display stability while enabling power savings.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If the active region size is fixed, then display hardware is simple, but the system cannot adapt to different display scenarios or user preferences

Engineering Contradiction:

Improvedisplay region flexibilityVSAvoiddisplay system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a display reconfiguration layer as an intermediary component between the display data source and the display panel. This layer acts as a mediator that handles the complexity of active region modification, allowing the rest of the display system to remain relatively simple while gaining adaptability. The reconfiguration layer translates high-level display requirements into modified display data streams with adjusted active region parameters.

Inventive Principle:

Principle #24Intermediary (Mediator)
