Description

Technical Field

[0001] The utility model relates to the technical field of OLED display, in particular to a novel OLED pixel arrangement structure. Background Art

[0002] The structure of an OLED display device primarily consists of a substrate and a matrix of pixel units. Each sub-pixel within a pixel unit is typically formed by depositing organic materials through a high-precision metal mask using vapor deposition technology, creating an organic electroluminescent structure at the corresponding sub-pixel position on the array substrate.

A key advantage of OLED displays is the ability to achieve true black and high contrast because each pixel emits light independently.
