Light Emitting Module Optical Correction via Segmented Light Guide

The patent applies local quality by creating non-uniform optical characteristics in specific regions of the light guide. Sectioning grooves are formed at predetermined positions to divide the light guide into multiple regions, and light adjusting holes are created at specific locations to locally modify light extraction. This allows different regions of the light guide to have optimized optical properties, correcting luminance and chromaticity distribution nonuniformities while maintaining the reduced thickness configuration.

The patent applies segmentation by dividing the light guide into multiple sections using sectioning grooves. These grooves create distinct regions that can be independently optimized for optical performance. By segmenting the light guide, the patent can address local optical nonuniformities in different areas, ensuring overall optical characteristic correction across the entire display panel while maintaining thinness.

The patent merges multiple functions into the light guide structure itself. The light guide simultaneously serves as the light distribution medium and contains the optical characteristic correcting elements (sectioning grooves and light adjusting holes) integrated within it. This consolidation avoids adding separate correction components, thereby improving optical characteristics while minimizing increases in device complexity.

The light guide acts as an intermediary element that mediates between the light sources and the liquid crystal panel. By incorporating correction elements within the light guide, the patent uses this intermediary structure to optimize light distribution and correct optical nonuniformities, achieving improved optical characteristics without directly complicating the overall device architecture.
