Abstract

The invention provides an OLED display and a manufacturing process thereof. The OLED display includes a substrate layer, an OLED light emitting layer, an encapsulation layer, a touch screen, and a cover plate. The cover plate includes a first region, and a second region and a third region which are arranged on the two sides of the first region and separated from each other. The second region and the third region each include two first organic layers and one or more first water blocking layers arranged between the two first organic layers, and a third organic layer is arranged between every two adjacent first water blocking layers. The first region includes two first organic layers and a second organic layer arranged between the two first organic layers. A protective layer of which the hardness is greater than that of the first organic layers is arranged on the outer surface of the cover plate. The cover plate can be bent, and the water blocking performance of the display is improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to an OLED display and a manufacturing process thereof. 【Background technique】 [0002] Existing displays mainly include liquid crystal (Liquid Crystal Display, LCD) displays and OLED (Organic Light Emitting Diode, OLED) displays. Among them, OLED displays have many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-color display, etc. It is recognized by the industry as the display with the most development potential. [0003] Traditional display cover materials are mostly rigid glass or resin (such as PMMA), plus functional layers, such as hardened layers. Wherein, the hardened layer can be an inorganic material, such as SiO2 and the like. The glass display cover cannot be bent, which does not c...
