Abstract

High volume consumer electronic devices are typically specified and designed in such a manner that a single orientation is implemented for maximum appeal to the broadest population of intended users. Such design solutions are often perceived to be inconvenient in the eyes of individual users who value the product from their individual modes of use. It is obvious to one skilled in human factors sciences that there is a large variance in the way individuals use these challenges. Often, a device is used by either the patient or caregiver. In such scenarios, the ideal orientation of the alphanumeric characters and icons on the liquid crystal display depend on the highly variable manner of use. Devices of the invention overcome such limitations by enabling selectable or adaptable user display orientations.

Title:

Liquid Crystal Displays with User Selectable Inverted or Multidirectional Orientations

Abstract: High volume consumer electronic devices are typically specified and designed in such a manner that a single orientation is implemented for maximum appeal to the broadest population of intended users. Such design solutions are often perceived to be inconvenient in the eyes of individual users who value the product from their individual modes of use. It is obvious to one skilled in human factors sciences that there is a large variance in the way individuals use these challenges. Often, a device is used by either the patient or caregiver. In such scenarios, the ideal orientation of the alphanumeric characters and icons on the liquid crystal display depend on the highly variable manner of use. Devices of the invention overcome such limitations by enabling selectable or adaptable user display orientations.

Background:

Many consumer electronics provide a liquid crystal display as the most effective, convenient and inexpensive means of communicating universal information. While the display layout is usually a function of the type and amount of information, display size and orientation are often determined by subjective human factors decisions. Lightweight LCD computer monitors with supporting software are available that permit users to easily change the orientation of their monitor to best suit the application with a simple display rotation and button press to toggle from portrait to landscape. The same ease of use can be applied to portable consumer appliances to optimize the for right or left handed users, or instances where a device designed for an individual’s personal use is operated primarily by another party such as a companion or care provider. This applies to inexpensive seven segment plus icon liquid crystal displays as well as higher resolution matrixed LCD or polymer organic-LED based displays.

Summary:

In its simplest implementation, the invention consists of a selectable option or mechanical rotation to invert the desired user interface display orientation. One embodiment of the invention enables an individual user to ‘soft’ flip the entire face or display of a consumer device 180°. This could be accomplished using a special display layout that is symmetrical about its center axes. The preferred orientation for use det...
