Abstract: An angle setter secured to respective surfaces of two or more modular units of a modular display system helps to provide or enable a predetermined overall angle or a predetermined overall amount of curvature for the modular display system. The angle setter has a predetermined angle proportional to a separation angle between the two or more modular units, to a radius of curvature, or proportional to a center angle of a display arc. The angle setter includes one or more pins and one or more fasteners to secure the angle setter to the respective surfaces of the two or more modular units. The angle setter is a component of an interconnecting sub-system of the modular display system.

Abstract: A modular interlocking display system incorporates revolving latches, alignment guides, interlocking finger joints, and registration side-lock blocks to securely and rigidly link multiple modular units. The display system may include groups of modular display panels with bi-level locking to secure the display panels individually and as a group to a support frame of the display system to provide indoor and outdoor large-scale display. Tight tolerances are maintained during assembly in order to minimize gaps and deflections between display panels and to maximize resolution. The latches may include different types and configurations of revolving latches. The modular units may be positioned together to obtain almost any configuration while simultaneously being rigidly and securely interlocked.
