Light Guide Plate Fixing Hole Light Bouncing

The patent removes the external black tape component and extracts the light-blocking function directly into the light guide plate structure by forming black-colored pattern parts (first and second pattern parts) integrally with the light guide plate through injection molding, thereby eliminating the separate taping process while maintaining light uniformity

The patent merges the light-blocking function (previously performed by separate black tape) with the light guide plate structure itself by integrating the first pattern part and second pattern part into the light guide plate as integral components, combining multiple functions into a single molded piece

The patent eliminates the separate black tape material cost and the additional labor costs associated with the taping process by extracting the light-blocking function into the injection molding process itself, where the first and second pattern parts are formed integrally with the light guide plate in a single manufacturing step

The light guide plate structure provides its own light-blocking function through the integrated first and second pattern parts that are self-formed during injection molding, eliminating the need for external materials and separate manufacturing processes

The patent applies different pattern configurations locally around each fixing hole (first pattern part near the hole, second pattern part further away) with varying depths and densities to locally control light scattering and blocking, allowing multiple fixing holes to be present while maintaining overall brightness uniformity through localized optical management

The patent uses an excessive amount of light scattering and blocking action in the regions around fixing holes through the first and second pattern parts, which are designed to compensate for the light-blocking effect of the holes themselves, ensuring that even with multiple holes the overall brightness remains uniform
