Solution Overview
Problem
Wearable computing devices face challenges in integrating displays that accommodate three-dimensional covers while ensuring protection and functionality, particularly in providing independent control and touch-sensitive interfaces for different display areas.
Innovation Solution
A display design for wearable computing devices featuring a first and second display area with distinct pixel configurations, each coupled to a dedicated conductor and memory buffer, allowing independent control and touch-sensitive functionality, and integrated within a three-dimensional cover with flexible connecting areas to accommodate curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a display is integrated within a three-dimensional cover, then the display conforms to the cover shape and provides protection, but the display structure becomes more complex and requires multiple display areas with independent control
Solution Approach 1:
The display is divided into multiple display areas (first display area, second display area with first and second portions) that can be independently controlled. Each display area has its own pixel matrix and can be addressed separately through dedicated conductors and memory buffers, allowing the display to conform to the three-dimensional cover shape while maintaining manageable structural complexity through modular organization
Solution Approach 2:
The display transitions from a traditional two-dimensional flat structure to a three-dimensional configuration that follows the cover's curved surface. The second display area wraps around portions of the first display area's periphery, creating a multi-dimensional display surface that adapts to the housing's three-dimensional geometry
2Ease of operation
If multiple display areas are created with independent control, then touch-sensitive functionality is enhanced, but the number of conductors and memory buffers increases
Solution Approach 1:
The display is segmented into multiple independently controllable areas, each with its own pixel matrix, conductors, and memory buffer. This segmentation enables independent touch-sensitive functionality for each display area, allowing users to interact with different portions of the display separately while maintaining organized electrical connections through dedicated conductor paths
Solution Approach 2:
Multiple display areas share common functional capabilities including touch sensitivity, independent control, and visual display. Each display area can function as a complete interactive interface, providing universal touch-sensitive functionality across the entire display surface while distributing the control burden across multiple memory buffers and conductor sets
3Area of stationary object
If the second display area wraps around the periphery of the first display area, then the display utilizes the three-dimensional cover space more effectively, but gaps may be defined between display portions
Solution Approach 1:
The second display area is configured to wrap around portions of the first display area's periphery, following the curved geometry of the three-dimensional cover. This curvature-based layout maximizes the use of available display space on the housing surface while accommodating the natural gaps that arise from wrapping around a three-dimensional form

AI summary
A display for an electronic device is provided. The display includes a first display area having a first plurality of pixels. The display includes a connecting area extending from a periphery of the first display area. The display includes a second display area having a second plurality of pixels. The second display area includes a first portion and a second portion. The first portion extends from the connecting area and around a first portion of the periphery of the first display area. The second portion extends from the connecting area and around a second portion of the periphery of the first display area. The second portion of the periphery is different than the first portion of the periphery of the first display area.
