Abstract

The invention provides an organic light emitting display panel, a device and a manufacturing method. The organic light-emitting display panel includes: a base substrate; a plurality of light-emitting units located on the base substrate; the light-emitting units include a first electrode, a light-emitting functional layer and a second electrode sequentially located on the base substrate; the light-emitting functional layer includes at least one At least one of the light-emitting functional layer, the first electrode, at least one sub-luminescent functional layer of the light-emitting functional layer, and the light-emitting surface of the second electrode is a concave-convex surface. The present invention provides an organic light-emitting display panel, a device and a manufacturing method to solve the problem of total emission on the light-emitting side in the prior art and improve the display brightness of the organic light-emitting display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel, a device and a manufacturing method. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display. Compared with LCD (liquid crystal display, liquid crystal display), OLED display does not require a backlight source, so OLED display is thinner and lighter. In addition, OLED display is also It has the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, and is increasingly used in various high-performance display fields. [0003] The light-emitting mechanism of OLED is that under the action of an external electric field, electrons and holes are respectively injected into the organic light-emitting material from the positive and negative poles, thereby migrating, recombining and decayi...
