[Display Glossary.zip] EP.48 : PDL (Pixel Define Layer)

The Pixel Define Layer (PDL) is an insulating layer that defines the light-emitting areas of OLED pixels and separates individual sub-pixels. OLED displays use organic materials that emit their own light. Before the organic light-emitting layer is formed, the PDL is patterned through photolithography, surrounding the areas where light is emitted.

A bezel is the border surrounding the active area, where the image is displayed. It contains the wiring and circuits that drive the pixels. Depending on the panel structure, it may also house a driver IC or connect to an FPCB.

[Display Glossary.zip] EP.46 : Aperture ratio

The aperture ratio refers to the proportion of a pixel's area through which light can pass or be emitted. This area is called the aperture. For displays of the same size, a higher aperture ratio results in a brighter display. It also improves energy efficiency, as less power is required to achieve the same brightness.
