  • Publication number: 20230207746
    Abstract: A light color conversion layer structure includes a pixel separation layer over a substrate. The pixel separation layer includes several separating components. The receiving region over the substrate is defined by adjacent separating components. The light color conversion layer structure also includes a first isolation layer continuously formed over the substrate and on the sidewalls of the separating components surrounding the receiving region. The first isolation layer continuously covers the top surface of the substrate and the sidewalls of the separating components adjacent to the receiving region. The light color conversion layer structure also includes a light color conversion unit within the receiving region and on the first isolation layer. The light color conversion layer structure further includes a second isolation layer on the first isolation layer and the light color conversion unit. The second isolation layer covers the first isolation layer and the light color conversion unit.

  • Patent number: 8168689
    Abstract: A high optical contrast pigment and colorful photosensitive composition employing the same are disclosed. The composition comprises a solvent, an alkali-soluble resin, reactive monomer, and a modified pigment which has low crystallization. The low crystallization degree means that the grain size variation R is not more 80%, wherein the grain size variation R is represented by a formula R=G1/G0×100%, G0 is the original grain size, and G1 is the grain size after modification.
