Foldable electronic display

Abstract

A foldable electronic display (10), also known as a variable or changeable message sign, displays important or emergency messages for the control of roadway and highway traffic. The self-contained foldable electronic display (10) is lightweight and portable and can be handled and setup easily and quickly by one person, on a multiplicity of structures. The display (10) may be stowed in the luggage compartment of highway maintenance and emergency response vehicles in a folded orientation when not in use. During use, the display (10) displays a stored or newly created message. A software lockout feature prevents the message from being changed using on-board controls by unauthorized personnel, eliminating the need for mechanical security measures. An optional mounting bracket (22) apparatus assures that the foldable electronic display (10) is held in an open orientation. The mounting bracket (22) apparatus is installed in a manner that is tamperproof and does not allow unauthorized access to mounting hardware (40).

Description

technical field [0001] The present invention relates to electronic message boards and displays, and more particularly to a portable electronic display having luminable elements. One possible application is to provide information or emergency information to the public. Background technique [0002] Police and emergency personnel use a variety of means (eg, signs and displays, flares, flashing lights, flashlights) to warn of approaching traffic accidents or emergencies. Illuminable electronic change display boards are one of the most effective devices for alerting approaching vehicles and delivering appropriate instructions to vehicles. In order to improve safety, it is very important for police and emergency personnel to be able to dispatch and configure variable display signs as quickly as possible at the scene of an accident or emergency, because the possibility of civilian and emergency personnel casualties will increase with the dispatch and deployment of variable displa...

AI Technical Summary

Problems solved by technology

Therefore, the display board cannot be mounted directly to a vehicle or to a portable or fixed pole

In this restrictive installation concept, the position and orientation of the trailer are integral to the operation of the signage, limiting the ability to quickly deploy the signage in the optimal position during an emergency

[0007] Another disadvantage of display panels known in the art is that without securing the controls in a locked compartment, the display panels have no security features to prevent information from being altered inadvertently or by unauthorized users
