Display Device Light Shielding and Absorbing Layers

The light control system is segmented into three distinct functional layers: a light shielding layer (with front and rear films) positioned at the rear substrate, a light absorbing layer positioned at the front substrate, and a liquid crystal layer between them. Each layer performs a specific function in filtering and controlling light wavelengths, enabling precise color reproduction without requiring complete redesign of the entire backlight system.

The patent introduces intermediary light control layers between the backlight unit and the display panel. The light shielding layer acts as a mediator to block specific wavelengths from the backlight, while the light absorbing layer further refines the spectrum. These intermediary layers enable the conventional backlight to produce accurate colors without direct modification to the backlight unit itself.

The light shielding layer merges multiple functions into a single integrated component: the front film serves as both a structural support and a light filtering medium, while the liquid crystal layer between the front and rear films provides both optical modulation and thermal management. This merging approach allows color temperature control without adding separate independent components for each function.

The light shielding layer is designed as a multi-functional component that simultaneously controls light distribution, regulates color temperature, and maintains structural integrity. The liquid crystal layer within the shielding structure provides both optical filtering and electrical controllability, enabling multiple functions from a single added layer rather than requiring separate components for each function.
