Problems solved by technology

[0007] like figure 2 As shown, when the light emitted by the organic light-emitting layer of the organic light-emitting diode OLED in the prior art passes through the anode or cathode materials above and below, part of the light will be reflected because it has a certain incident angle. Full emission will occur when the light is large, and this part of the light will be wasted to a large extent

Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] Aiming at the problems in the prior art that the light in the organic light-emitting unit of the organic light-emitting diode OLED is totally reflected during the transmission process of each structural layer, resulting in low light utilization rate and insufficient brightness, the present invention provides an organic light-emitting diode OLED, It can improve the light utilization rate and brightness of the organic light emitting diode (OLED).

[0030] Such as image 3 As shown, the organic light emitting diode OLED provided by the present invention includes a base substrate 100 and at least one organic light emitting unit 200 formed on the base substrate 100; the outer light emitting surface of the organic ...

Abstract

The invention provides an organic light emitting diode (OLED) and a display device. The OLED comprises a substrate and at least one organic light emitting unit formed on the substrate; the outer-layer emergent surface of the organic light emitting unit is a convex curved surface. By the scheme, the outer-layer emergent surface of the organic light emitting unit is designed into the convex curved surface, a phenomenon that light emitted by the light emitting unit is totally reflected due to low refractivity in the transmission process can be effectively reduced, the light is limited in each structural layer, and the light intercepting rate can be improved, so that the utilization rate and brightness of the light are improved, and the problem that an OLED is low in brightness is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode (OLED) and a display device. 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 decaying in the organic light-e...
