Supporting Member for Uniform Adhesive Gap in Display Devices

A supporting member is introduced as an intermediary component between the display panel and functional panel. This supporting member includes a gap maintaining portion that physically sustains a uniform gap, and an adhesive introduction space that facilitates uniform adhesive distribution. The supporting member mediates the attachment process to ensure uniform adhesive coating without requiring complex external coating equipment.

The supporting member is prepared in advance with pre-formed gap maintaining portions and adhesive introduction spaces. These features are created during the supporting member manufacturing process before assembly, allowing the uniform gap and adhesive distribution to be achieved automatically during the attachment process without requiring real-time adjustment or complex coating operations.

The supporting member performs multiple functions simultaneously: it maintains a uniform gap between panels, provides adhesive introduction spaces for uniform coating, and distributes pressure during attachment. By consolidating these functions into a single component rather than using separate elements for each function, the overall device complexity is minimized while achieving the desired manufacturing precision.

The gap maintaining function and adhesive introduction function are merged into a single supporting member structure. The supporting member integrates the physical gap sustenance feature with the adhesive distribution channels, eliminating the need for separate gap maintainers and adhesive applicators, thus reducing component count while maintaining both functions effectively.

The supporting member features locally optimized adhesive introduction spaces positioned at specific locations where adhesive needs to be introduced. These spaces have dimensions and geometries tailored to facilitate adhesive flow from high viscosity states, allowing the adhesive to be drawn into the spaces and distributed uniformly despite its high viscosity. The local structure compensates for the material property limitation.

The supporting member's adhesive introduction spaces are designed with specific dimensional parameters (size, shape, position) that change the flow characteristics of the high viscosity adhesive. By optimizing these geometric parameters, the adhesive can be introduced and distributed uniformly even in its high viscosity state, enabling both strong bonding and uniform coating.
