Display Device FPC Substrate Fixing Structure

The fixing structure is segmented into multiple fixing members distributed at different positions on the chassis. Each fixing member independently secures a portion of the FPC substrate, distributing the stress and preventing peeling. This segmentation allows the substrate to be fixed reliably while maintaining assembly simplicity.

The spacer acts as a counterweight element that applies a counteracting force to balance the restoring force of the FPC substrate. By positioning the spacer between the substrate and the chassis, it creates a mechanical equilibrium that prevents the substrate from peeling off when external forces are applied.

The fixing members and spacer are installed beforehand to create a pre-established positioning structure. This preliminary action ensures that the LED maintains its correct positional relationship with the light guide plate end face before any external forces are applied, preventing brightness distribution issues while enabling thin device design.

The spacer serves as an intermediary element between the FPC substrate and the chassis, providing a mechanical reference that maintains the correct distance and position of the LED relative to the light guide plate. This intermediary structure ensures consistent brightness distribution while allowing the device to remain thin.

The fixing members combine multiple functions: mechanical attachment, position stabilization, and stress distribution. By merging these functions into a single fixing structure, the flexible FPC substrate can maintain its compact design while achieving stable positioning that prevents peeling under external forces.

The spacer acts as a mediator that provides a mechanical reference and physical barrier between the FPC substrate and the chassis. This intermediary element stabilizes the substrate position without restricting its flexibility, allowing the device to remain compact while preventing substrate peeling.
