Flexible display and thin film packaging method thereof

Abstract

The invention discloses a flexible display and a thin film packaging method thereof. The thin film packaging method comprises steps: after surface processing is carried out on a middle region between a first carrier substrate and a second carrier substrate, a polymer solution is applied uniformly, and a corresponding first polymer thin film and a second polymer thin film are formed through heating, crosslinking and curing; on the first polymer thin film, a first blocking layer and an OLED device layer are sequentially formed; a second blocking layer is formed on the second polymer thin film, the second polymer thin film and the second blocking layer are separated from the second carrier substrate to serve as a polymer packaging film; curing processing is carried out around the polymer packaging film, and thus the second polymer thin film and the first polymer thin film are crosslinked and cured around to form polymer gel; and the polymer gel is cut, and the flexible display is separated from the first carrier substrate. The thin film packaging technology is simplified, the display device can be separated from the carrier substrate easily, and a bonding agent does not need to be used.

Description

technical field [0001] The invention relates to the field of flexible displays, in particular to a flexible display and a film packaging method thereof. Background technique [0002] In recent years, flexible displays have become a research hotspot in universities and research institutions at home and abroad, and are also the focus of major manufacturers competing for layout. Various manufacturing processes and technologies have been continuously improved, which has not only increased the screen size of flexible displays, but also continuously improved the display quality. Major manufacturers such as Samsung and LG have launched flexible AMOLED (active matrix organic light-emitting diode panel) display prototypes. Flexible displays use flexible substrate materials as device-carrying substrates, and require electrode layers, TFT matrix, display devices, and packaging layers to have a certain bending radius to achieve flexibility. [0003] Compared with ordinary displays, fle...
