A configurable panel display includes panel frames configurable to support respective panels, adjacent ones of the panel frames being pivotably connected along opposing edges, each panel frame having intersecting sides formed by tubular frame members, and a cap hinge assembly pivotably connecting two adjacent ones of the panel frames. Each cap hinge assembly includes two frame corner pieces, each frame corner piece interconnecting tubular frame members of two intersecting sides of a respective one of the adjacent ones of the panel frames. Each frame corner piece includes projections received within the interconnected tubular frame members, a central corner piece body from which each of the projections integrally extends, a hinge cap spanning the two frame corner pieces, and two fastening members, each fastening member connecting the hinge cap to a respective one of the frame corner pieces.
