Solution Overview

Problem

High-definition display devices face inefficiencies in processing and arranging sub-images due to high computation requirements and time consumption in existing random ranking and judging schemes for signal input, particularly with increased video information demands.

Innovation Solution

A display signal input method that groups sub-images based on edge matching, progressively forming higher-level sub-image units, ensuring correct edge alignment before outputting them for display, thereby reducing computational load and improving signal transmission timeliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a random ranking and judging scheme is used to arrange sub-images, then the arrangement can be completed, but the computation amount is great and time consumption is long

Engineering Contradiction:
Improvetime consumptionVSAvoidcomputation amount
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent segments the sub-image arrangement task into hierarchical levels. Sub-images are first grouped into base-level sub-image groups, then these groups are arranged in higher-level groups, and so on. This segmentation reduces the computational complexity by breaking down the overall arrangement problem into smaller, more manageable sub-problems at each level.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by pre-grouping sub-images into base-level sub-image groups before the actual arrangement process. This preliminary organization reduces the search space for subsequent arrangement operations, thereby reducing computation time and complexity.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If sub-images are divided and input separately for high-definition display, then the resolution requirement is met, but the signal transmission timeliness is reduced

Engineering Contradiction:
Improveimage resolutionVSAvoidsignal transmission timeliness
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent segments the high-resolution image into multiple sub-images that can be processed and transmitted in parallel. This segmentation enables simultaneous processing of multiple sub-images through the pipeline, maintaining high resolution while improving overall transmission efficiency through concurrent operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent establishes a continuous pipeline for sub-image processing where multiple sub-images are processed, arranged, and output in a continuous flow. The hierarchical arrangement method ensures that processing can proceed continuously without waiting for complete random verification, maintaining signal transmission timeliness while achieving high resolution.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A display device and a display signal input system and a display signal input method thereof are provided. The display signal input method includes: receiving sub-images (S101); grouping the sub-images into a plurality of sub-image groups of a base level (S103); judging information of edge matching between sub-image units in each sub-image group of a current level (S104); if edge matching between the sub-image units in each sub-image group of the current level is correct, grouping respective sub-image groups of the current level as sub-image units to form sub-image groups of a new level, and performing judgment again till edge matching between any two adjacent sub-images in an image formed by splicing the sub-images is correct (S105); and outputting information of the respective sub-images arranged in sequence to the display device (S106).
