Guide Panel Rib for Light Source Module Positioning

The guide panel acts as an intermediary component between the backlight unit and the light source module. It includes positioning structures such as ribs or grooves that physically guide and constrain the light source module during assembly, ensuring accurate positioning without requiring complex assembly procedures. This mediator structure resolves the contradiction by providing both ease of assembly through simple positioning features and reliability through stable light source module positioning.

The positioning function is merged into the guide panel structure itself, which is already present in the backlight unit. The guide panel integrates positioning ribs, grooves, or other constraining features as part of its existing structure, rather than adding separate fixing mechanisms. This merging approach provides reliable light source module positioning while avoiding increased device complexity from additional dedicated fixing structures.

The guide panel utilizes vertical or depth-dimensional positioning features (such as ribs extending upward, grooves cutting downward, or L-shaped positioning elements) rather than relying solely on horizontal space. This dimensional approach allows effective positioning and constraining of the light source module within the reduced horizontal space available due to narrow bezels, thereby maintaining manufacturing precision without sacrificing the aesthetic benefits of narrow bezel design.
