Abstract
A backlighted liquid crystal display assembly mounted on a circuit substrate. The circuit substrate has contact pads formed thereon for electrical connection with the assembly. The assembly includes a liquid crystal display (LCD) screen panel and an electroluminescent (EL) panel for providing backlighting of the LCD screen panel. Each panels is formed as a thin, flat panel and has contact pads for external electrical connection. The assembly also includes a pair of electrical-interconnection rubber members, each having a plurality of conductive areas formed of a conductive rubber material and a plurality of insulating area formed of an insulating rubber material and separating the conductive areas from each other. A retainer structure retains the LCD screen panel, the EL panel and the rubber members to the mounting surface of the circuit substrate while keeping them in a predefined positional relationship such that (i) one of the rubber members has a first portion disposed and compressed between the LCD screen panel and the mounting surface of the circuit substrate and a second portion disposed and compressed between the LCD screen panel and the EL panel and (ii) the conductive areas of the rubber members are in contact with and provide electrical interconnection among the contact pads of the circuit substrate, the contact pads of the LCD screen panel and the contact pads of the EL panel.
