ABSTRACT:
An inventive spacing structure is a unitary structure of uniform height including a multitude of rail members framed by and interconnected with a multitude of frame members. The frame and rail members project between a flat panel display's face and base panels across a substantial area of their facing surfaces. As a result, the unitary spacing structure spaces a substantial portion of the face panel away from the base panel in a substantially parallel spaced apart relationship with the base panel. Because the inventive spacing structure is a unitary structure, it can be conveniently manufactured apart from the flat panel display and then easily aligned with the image generating apparatus of the display. Thus, the unitary spacing structure can help to make flat panel displays less difficult, time-consuming and costly to manufacture. Also, the rail members and frame members of the unitary spacing structure make the structure stronger than conventional columnar spacers because the rails distribute the force they support. As a result, the unitary spacing structure can easily exceed 100 .mu.m in height and can thereby help increase the brightness of flat panel displays which are field emission displays.
