Abstract
Abstract A structure for mounting a liquid crystal display (LCD) in a portable computer and a method for making the mounting structure are described. The mounting structure absorbs the shocks associated with day-to-day handling of the portable computer including occasional dropping or compressing and thereby protects the LCD from damage. The mounting structure consists of resilient shock absorbers mounted along the edges or at the corners of the LCD and glass assembly which are sealed with the LCD glass and circuitry behind a transparent overlay while under compression. The sealed mounting structure acts as a suspension system which allows the LCD glass to float along a single plane only. Any shocks due to dropping, compressing, bending or deflecting are absorbed by the shock absorbers and the LCD remains unaffected. The mounting structure may be evacuated and hermetically sealed, which provides protection to the LCD glass and circuitry from humidity, dust and other contaminates as well.
