Abstract
A filter layer for a display and a method of preparing the filter layer, and a display including the filter layer are provided. The filter layer for a display includes oxide particles and nano-sized metal particulates adhered to the surface of the oxide particles. A surface plasma resonance (SPR) phenomenon is triggered at the interface of the oxide/metal to selectively absorb light of at least one predetermined wavelength.
Claims33
A filter layer for a display, comprising:
- oxide particles;
- and
- nano-sized metal particulates adhered to a surface of the oxide particles with a surface plasma resonance phenomenon being triggered at corresponding interfaces of the nano-sized metal particulates and the oxide particles to selectively absorb light at least at one predetermined wavelength of light.
A filter layer prepared by a process, the process comprising:
- dispersing an oxide in water to form an oxide sol;
- adding a metal salt, a reducing agent, and a dispersing agent to an organic solvent to prepare a metal colloid solution;
- mixing the oxide sol with the metal colloid solution to prepare a coating solution with a metal colloid of the metal colloid solution being dispersed in the oxide sol;
- applying the coating solution on a face panel of a display to form a filter layer;
- and
- drying the filter layer at room temperature.
A display, comprising:
- at least one filter layer, the at least one filter layer comprising oxide particles and nano-sized metal particulates adhered to surface of the oxide particles with a surface plasma resonance phenomenon being triggered at corresponding interfaces of the nano-sized metal particulates and the oxide particles to selectively absorb light at least at one predetermined wavelength of light.
A method of preparing a filter layer, comprising:
- dispersing an oxide in water to form an oxide sol;
- adding a metal salt, a reducing agent, and a dispersing agent to an organic solvent to prepare a metal colloid solution;
- mixing the oxide sol with the metal colloid solution to prepare a coating solution with a metal colloid of the metal colloid solution being dispersed in the oxide sol;
- applying the coating solution on a face panel of a display to form a filter layer;
- and
