Abstract

The application discloses an organic light emitting display panel and a manufacturing method thereof. The organic light-emitting display panel includes a backplane, an electroluminescent device, and an adhesive film layer stacked in sequence, and also includes: a convex lens array, which is arranged 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 present application, by arranging a convex lens array on the side of the adhesive film layer close to the electroluminescent device, the angle of light output can be changed to solve the problem of preventing light from entering the interface between the electrode layer and the cover plate and the interface between the cover plate and air. The total reflection problem occurs.

Description

technical field [0001] The present disclosure generally relates to the field of display, and more particularly, 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 a next-generation product with excellent characteristics such as high flexibility, wide viewing angle, high contrast, low power consumption, thin thickness, high response rate, flexible panels, wide operating temperature range, full color, simple structure and simple manufacturing. The mainstream technology of display has been favored by major display manufacturers. [0003] However, due to the huge difference between the externa...
