Curved Screen Lamination Structure for Bubble-Free Pressure Transfer

The patent employs a deformation bearing member with a deformation portion that can dynamically change its shape during the lamination process. The deformation portion transitions from an initial state to a deformed state under pressing force, enabling the support surface to adapt its geometry to match the curved cover plate's profile. This dynamic adaptation ensures uniform pressure distribution across the flexible screen, preventing air bubble formation and improving lamination quality.

The patent changes the geometric parameters of the support surface by deforming the deformation portion. The inclination angle of the support surface is adjusted from an initial value to a deformed value that matches the curvature of the cover plate. This parameter change enables the silicone pad to conform to the curved surface, ensuring even pressure distribution and eliminating air bubbles during lamination.

The deformation bearing member provides a dynamic solution that maintains operational simplicity while achieving uniform pressure distribution. The deformation portion automatically adjusts its shape in response to applied pressure, conforming to the curved cover plate profile. This self-adjusting mechanism eliminates the need for complex pressure control systems, maintaining ease of operation while ensuring precise and uniform pressure distribution across the lamination surface.

The patent changes the geometric parameters of the bearing member during the lamination process. The deformation portion transitions from an initial geometry to a deformed geometry that matches the cover plate curvature. This parameter change occurs automatically under applied pressure, maintaining process simplicity while achieving uniform pressure distribution without requiring complex control mechanisms.
