Wearable Display Region Segmentation for Power Optimization

Solution Overview

Problem

Wearable display devices face challenges in efficiently managing power consumption and user experience due to the need for larger, more flexible displays, which require balancing image quality and energy efficiency across different regions of the device.

Innovation Solution

A wearable display device with multiple regions, each capable of displaying images at varying qualities, driven by a processor that selects the appropriate region based on content type, user preference, biometric information, and battery life, allowing for dynamic adjustment of image quality and region usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the display size is increased to enhance user experience, then the display area is improved, but the power consumption increases

Engineering Contradiction:

Improvedisplay areaVSAvoidpower consumption

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The display is divided into multiple regions with different image quality characteristics. The processor selectively activates only the regions needed for displaying specific content, rather than rendering the entire large display at full quality. This segmentation allows the system to maintain a large display area while reducing overall power consumption by leaving portions of the display inactive or operating at lower quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display are assigned different image quality levels based on their location and the content being displayed. The processor determines which regions require high image quality and which can operate at reduced quality, allowing optimized power consumption across the display area while maintaining acceptable user experience in the active regions.

Inventive Principle:

Principle #3Local quality

2Manufacturing precision

If the image quality is improved across the entire display, then the user experience is enhanced, but the power consumption increases

AI summary

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for displaying information in various display regions within wearable display devices in a manner that enhances user experience and extends battery life. The wearable display devices may include a flexible display region and may be capable of operating in a wrinkled state. In some aspects, the wearable display devices may be capable of displaying images at different image qualities in the separate display regions. For example, in some implementations, wearable display devices include a first display region that has a higher pixel density than the second display region. In some aspects the wearable display devices may be configured to determine and/or select a display region in which specific image content is displayed. For example, text may be displayed region best suited to display text while video is displayed in region best suited to display video.
