Transparent Display Spacer Suppressing Substrate Misalignment

The patent removes the filler layer entirely and replaces it with transparent spacers that are integrated directly into the substrate structure. The spacers are formed as protrusions on the first substrate that extend into the second substrate, eliminating the need for separate filler materials that would outgas and cause element degradation.

The patent uses transparent spacer materials that are integrated with the substrate materials (such as frit glass or transparent resins) to form a composite structure. This composite approach maintains cell gap stability while avoiding the outgassing issues associated with traditional filler layers, as the spacer material is chemically bonded to the substrates.

The transparent spacers act as intermediary elements between the first and second substrates. These spacers provide physical guidance and positioning features that ensure precise alignment during the bonding process, while still allowing for a relatively simple manufacturing procedure. The spacers are formed with specific geometries that guide substrate placement and prevent misalignment.

The transparent spacers are formed on the first substrate before the bonding process. This preliminary formation of alignment features allows the substrates to be precisely positioned during bonding, ensuring optimal alignment without requiring complex real-time adjustment mechanisms during the assembly process.

The patent applies different properties to different parts of the substrate system. The second substrate is made transparent in the display areas where optical performance is critical, while the transparent spacers provide localized structural support at specific positions. This local differentiation allows the substrate to maintain transparency where needed while receiving mechanical support where required.

The patent employs composite material structures where transparent spacer materials (such as frit glass or transparent resins) are integrated with the substrate materials. These composite structures provide both the optical transparency required for display functionality and the mechanical strength needed to prevent substrate sagging, combining the benefits of both transparent and structurally robust materials.
