Solution Overview

Problem

Current display devices with curved screens face challenges in maintaining high image quality and reducing distortion, leading to an unnatural viewing experience due to potential image protrusions and luminance issues.

Innovation Solution

An image processing device that generates a peripheral image to extend the frame image and performs coordinate conversion using a look-up table to align the viewpoint position, ensuring the image is displayed without luminance gaps and maintaining high quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If coordinate conversion is performed on the original frame image for curved screen display, then distortion is reduced, but image quality deteriorates due to luminance gaps and unnatural viewing experience

Engineering Contradiction:

Improvedistortion correctionVSAvoidimage quality

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies preliminary action by generating a peripheral image before coordinate conversion. The image generation section creates additional image data in the peripheral region of the frame image, which is then used during coordinate conversion to fill gaps and maintain luminance continuity on the curved screen, preventing unnatural viewing experiences

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the display screen is curved to enhance feeling of presence, then immersion is improved, but image quality deteriorates due to distortion and luminance issues

Engineering Contradiction:

Improvefeeling of presenceVSAvoidimage quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by differentiating image processing between central and peripheral regions. The image generation section specifically processes the peripheral region to generate additional image data, while the central region maintains original quality. This localized approach ensures high image quality in the critical viewing area while enabling curved screen immersion

Inventive Principle:

Principle #3Local quality

3Reliability

If peripheral image is generated and coordinate conversion is performed, then image quality is improved, but device complexity increases

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the image generation section to perform multiple functions: generating peripheral image data, preparing for coordinate conversion, and ensuring luminance continuity. This multi-functional approach consolidates what could be separate complex processes into a unified processing pipeline, managing device complexity while improving image quality

Inventive Principle:

Principle #6Universality (Multi-functionality)
