Abstract

A touch screen mounting assembly for an LCD monitor is disclosed. The assembly includes a rear cabinet including a pair of fastener supports provided on top and bottom edge portions of the rear cabinet, an LCD module securely fastened within the rear cabinet, a touch screen adhesively attached to the rear cabinet; and a front cabinet including a pair of slip fit fasteners. The slip fit fasteners are able to have slip fit connections with the fastener supports, respectively, for preventing the front cabinet from becoming disengaged from the rear cabinet. Each fastener support includes an extension member extended forward from the rear cabinet, and a recessed channel, where each slip fit fastener includes an extension member extended backward from the front cabinet, and a detent which has slip connection with the recessed channel.

Claims
