Abstract

Breakage of glass Liquid Crystal Displays (LCDs) in portable communications products, including pagers, is one of the limiting factors in a product's drop test performance. Thus, the design of the mounting system for the glass in the pager directly impacts a pager's drop test performance. Typically, the back of the LCD is supported by slots in the plastic housing on the ends of the glass, or by a rigid member along the length of the glass, sometimes with a rubber sheet in between the glass and the rigid member. These configurations have been designed to reduce the shock transmitted to the glass during drop. For example, the rubber durometer and thickness are selected to absorb shock energy. How- ever, there are limitations to drop performance with this technology.
