Abstract

The invention discloses an organic light-emitting display panel and a manufacturing method thereof. The organic light-emitting display panel includes a backing plate, an electroluminescent device andan adhesive film layer which are sequentially stacked and further includes a convex lens array which is disposed on a side of the adhesive film layer close to the electroluminescent device and is provided with convex lenses arranged in an array. According to the technical solution provided by the embodiment of the invention, by setting the convex lens array on the side of the adhesive film layer close to the electroluminescent device, the light-emitting angle can be changed to prevent the total reflection problem of light at an interface between the electrode layer and a cover plate and an interface between the cover plate and the air.

Description

technical field [0001] The present disclosure generally relates to the display field, and in particular, relates to an organic light emitting display panel and a manufacturing method. Background technique [0002] Organic light-emitting diode (English: Organic Light-Emitting Diode, abbreviation: OLED), also known as organic electroluminescence display (English: Organic Electroluminescence Display, abbreviation: OELD), is a different type of product from thin-film transistor liquid crystal display. The former has self-luminescence It is recognized as the next-generation The mainstream display technology has been favored by major display manufacturers. [0003] However, due to the huge difference between the external quantum efficiency and internal quantum efficiency of OLEDs, the development of OLEDs is greatly restricted. The light extraction efficiency of conventional OLED devices is about 20%, so how to improve the light extraction efficiency has become a research hotspo...
