Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional display systems for wireless devices often produce black bars when trying to fit non-square aspect ratio content onto square displays, leading to a need for improved techniques to match typical video content without cropping.

Innovation Solution

Implementing a panoramic display system with multiple display regions, where image compression and scaling are applied progressively based on proximity to the edges, allowing a square display to emulate a non-square aspect ratio by adjusting pixel density in lateral regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional best fit algorithms are used to fit content to non-square displays, then the content can be displayed on the square display screen, but black bars appear on the display

Engineering Contradiction:

Improvecontent display compatibilityVSAvoiddisplay area utilization

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The display screen is divided into multiple display regions including a central display region and multiple lateral display regions. Different compression factors are applied to different regions, with the central region using a first compression factor and lateral regions using a second compression factor, allowing full utilization of the square display area while maintaining content aspect ratio

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the display screen receive different levels of image compression. The central display region maintains higher quality with a first compression factor, while lateral display regions apply a second compression factor. This allows the entire screen to be utilized without black bars while preserving visual quality where most needed

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If image compression is applied uniformly across the entire display, then the content fits the square display, but image quality deteriorates in all regions

Engineering Contradiction:

Improvedisplay format compatibilityVSAvoidimage quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies different compression factors to different display regions. The central display region uses a first compression factor that preserves higher image quality, while lateral display regions use a second compression factor. This differential approach maintains overall display compatibility while preserving image quality in the most important viewing area

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of applying uniform compression across the entire display, the patent applies compression selectively and differentially to different regions. The central region receives less aggressive compression (first compression factor) while lateral regions receive more compression (second compression factor), optimizing the balance between fit and quality

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Various embodiments of a panoramic display for a wireless device are described. In one embodiment, a wireless device may include a display comprising a plurality of display regions. The display regions may include a central display region and multiple lateral display regions arranged to provide a panoramic display. Image compression and/or scaling may be applied to media content that is to be displayed in one or more of the lateral display regions based on the proximity of the lateral display region to the edge of the display.
