PIXEL ISOLATION STRUCTURES AND METHODS OF MAKING THEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18244466 titled 'PIXEL ISOLATION STRUCTURES AND METHODS OF MAKING THEM

Simplified Explanation

The patent application describes methods for creating a patterned LED substrate with pixel isolation structures using a light absorption material containing photocurable compounds and ultraviolet light absorbing materials. The process involves exposing the material to patterned light to cure it into pixel isolation structures, followed by depositing an isotropic layer on top and side portions of the structures.

• LED structures are formed on a substrate layer to create a patterned LED substrate.
• A light absorption material is deposited on the patterned LED substrate, containing photocurable compounds and ultraviolet light absorbing materials.
• Exposing a portion of the light absorption material to patterned light cures it into pixel isolation structures.
• An isotropic layer is deposited on top and side portions of the pixel isolation structures.
• The LED structures are free of the as-deposited isotropic light reflecting layer.

Original Abstract Submitted

Processing methods are described that include forming a group of LED structures on a substrate layer to form a patterned LED substrate. The methods also include depositing a light absorption material on the pattered LED substrate, where the light absorption material includes at least one photocurable compound and at least one ultraviolet light absorbing material. The methods further include exposing a portion of the light absorption material to patterned light, wherein the patterned light cures the exposed portion of the light absorption material into pixel isolation structures. The methods additionally include depositing an isotropic layer on a top portion and a side portion of the pixel isolation structures, where the LED structures are substantially free of the as-deposited isotropic light reflecting layer.
