Backlight Module Assembly to Suppress Reflective Sheet Bulging

The connecting structure transitions from a static rigid connection to a dynamic adaptive connection. The inclined guiding surface allows the post to move along a predetermined path during thermal expansion, enabling the structure to adapt to temperature changes while maintaining connection integrity and preventing bulging that would harm optical quality

The connecting structure exploits thermal expansion parameter changes by designing the inclined guiding surface that converts the reflective sheet's thermal expansion into controlled movement along the slope. This transforms the harmful expansion into a useful mechanism that maintains contact between components while accommodating size changes, preventing LED failures and preserving optical quality

The connecting structure is specifically designed to accommodate thermal expansion of the reflective sheet. The inclined guiding surface provides a pathway that allows the reflective sheet to expand in the horizontal direction while the post moves along the slope, converting thermal expansion into beneficial movement that maintains structural stability and prevents upward bulge

The connecting structure introduces a dimensional transformation by using an inclined surface. The thermal expansion that would normally cause vertical bulging is redirected into horizontal movement along the inclined guiding surface, effectively converting a harmful three-dimensional deformation into a controlled two-dimensional movement that maintains optical quality
