Title: OLED DISPLAY AND MANUFACTURING METHOD THEREOF
Abstract:
Provided are an OLED display and a manufacturing method thereof. In the OLED display, corresponding outer edges of each organic buffer layer (321) in a thin film encapsulation layer (300) and an inorganic passivation layer connected to and positioned under the organic buffer layer (321) form a step region. Each step region is coated with diamond-like carbon (331). The diamond-like carbon is applied in lateral encapsulation. An outer side of each organic buffer layer in the thin film encapsulation layer is coated with the diamond-like carbon, thereby effectively protecting an OLED device (200) from damage caused by water and oxygen entering from a side surface thereof, and preventing loss of light emitted by a top-emitting device and passing through the diamond-like carbon.
