Tiled Display Panel Roller-Rail Alignment Under Thermal Expansion

The patent implements a dynamic adjustment mechanism using rollers and rails that allow display panels to move and self-align during thermal expansion and contraction. The rollers can rotate along the rails, enabling the panels to dynamically adjust their positions and maintain proper alignment despite temperature changes, resolving the contradiction between large display area and manufacturing precision.

The patent changes the physical state and properties of the connection structure by introducing movable rollers instead of fixed connections. This parameter change allows the system to adapt to thermal expansion by changing the positional parameters of panels dynamically, maintaining alignment precision while preserving the large display area achieved through tiling.

The patent employs a flexible connection mechanism using rollers that can move along rails, creating a compliant joint between rigid display panels. This flexible connection allows the panels to accommodate thermal expansion and contraction without generating excessive stress, while still maintaining proper alignment through the guiding action of the rails.

By transitioning from a static rigid fixation to a dynamic roller-rail system, the patent allows the panels to move freely during thermal cycles. The rollers can rotate and slide along the rails, absorbing thermal stress while maintaining positional accuracy, thus resolving the contradiction between maintaining position and preventing thermal stress damage.
