Abstract

The plasma panel offers several advantages over the CRT as a display device. It has long life, a thin profile, a flat screen, and is flicker- and distortion-free. The function of plasma panel packaging is to physically support, protect, and interconnect the panel and associated electronics in such a way that its performance, appearance, and maintainability are enhanced. In addition, the package should insure that minimum degradation occurs in shipping, storage, and operating environments. Achieving these objectives at minimum cost presents difficulties because of the fragile and highly reflective characteristics of plate glass, the extensive electronic circuitry needed to drive it, and the large number of interconnections required between the rigid glass and the electronics.

Plasma Panel Packaging

The plasma panel offers several advantages over the CRT as a display device. It has long life, a thin profile, a flat screen, and is flicker- and distortion-free. The function of plasma panel packaging is to physically support, protect, and interconnect the panel and associated electronics in such a way that its performance, appearance, and maintainability are enhanced. In addition, the package should insure that minimum degradation occurs in shipping, storage, and operating environments. Achieving these objectives at minimum cost presents difficulties because of the fragile and highly reflective characteristics of plate glass, the extensive electronic circuitry needed to drive it, and the large number of interconnections required between the rigid glass and the electronics. This article presents a packaging design for a large-size high-resolution panel. The fragility of glass presents unique packaging problems. The amount and type of protection required are determined by safety, economics, and the display environment. These characteristics dictate the use of special glass or protective packaging to prevent breakage. The manufacturing processes and the transparency requirements limit the material to plate glass, placing the protection totally on the package design. Panel packaging is further complicated by the requirements that electrical connections be made along most of all four edges of the panel, and that the frame be electrically conductive to serve as a high frequency current return for the electronics. These requirements limit access to the edges of the panel for mounting and limit the choices for frame material. As shown in Fig. 1, a resilient mounting system was developed using a flexib...
