LCD Glass Diffuser Guide Bar Adhesive Configuration

The patent applies local quality by providing a guide bar at specific locations (edges and corners) of the main frame where light reflection is critical. The guide bar has a specific reflective surface configuration that locally enhances light reflection toward the liquid crystal panel, ensuring uniform light distribution particularly at the edges and corners where dark portions would otherwise occur due to the narrow bezel design.

The guide bar acts as an intermediary element between the main frame and the glass diffuser assembly. It provides a controlled light reflection interface that mediates the optical interaction, ensuring that light is properly directed and distributed even when the glass diffuser is positioned close to the liquid crystal panel. This intermediary structure prevents direct harmful optical effects while maintaining the reduced thickness design.

The patent segments the adhesive member into two functional parts: a first adhesive member with a first width for attaching the glass diffuser to the main frame, and a second adhesive member with a second width greater than the first width for attaching the liquid crystal panel to the glass diffuser. This segmentation allows the wider adhesive structure to be positioned in the optical path where it provides stability without contributing to the visible bezel width, as it is located at the back edge of the liquid crystal panel.
