LCD Device Heat Dissipation via Staggered Frame Vents

The patent extracts the heat dissipation function from the traditional sequential conduction-convection path and creates a dedicated air convection channel through air vents. The air vents are thermally connected to the LED light source and extend to the external environment, allowing heat to be directly carried away by air flow without relying on sequential heat conduction through multiple components, thereby significantly improving heat dissipation efficiency and protecting display reliability.

The patent segments the through hole into two separate components: a middle frame through hole and a front frame through hole. These two holes are staggered rather than aligned, creating a stepped configuration that allows heat to dissipate through both openings while the misalignment prevents direct light paths from the light source to the external environment, thus solving both heat dissipation and light leakage requirements simultaneously.

The patent resolves the conflict between light leakage prevention and heat dissipation by transitioning from a one-dimensional alignment problem to a two-dimensional spatial arrangement. The middle frame through hole and front frame through hole are positioned at different locations and orientations, creating a three-dimensional staggered configuration. This dimensional change allows heat to escape through multiple pathways while blocking direct light transmission, as the staggered positions prevent collinear light paths while maintaining thermal connectivity.
