COLOR CONVERSION FILM WITH ALD SEALED EDGES

The present invention relates to edge-sealed color conversion films. The color conversion film, upon excitation with blue light, emits light in the visible range. The edge sealing contains inorganic material, having a thickness of 1 - 500 nm, a thickness standard deviation of less than 10%, is locat...

More Information
Summary:The present invention relates to edge-sealed color conversion films. The color conversion film, upon excitation with blue light, emits light in the visible range. The edge sealing contains inorganic material, having a thickness of 1 - 500 nm, a thickness standard deviation of less than 10%, is located on all edges of the native color conversion film, thereby providing a complete and defect-free covering of the edges. The invention further provides to the manufacturing of such edge-sealed color conversion films using ALD techniques.
