Embodiment Construction

[0027] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

[0028] In the present invention, the same or corresponding components are represented by the same reference numerals regardless of the figure number, and throug...

Abstract

The invention provides an organic electroluminescent device. The organic electroluminescent device comprises a transparent conductive layer, a light-emitting unit layer, a transparent insulator dielectric layer and an electrode layer which are sequentially stacked. The light-emitting unit layer comprises a first light-emitting unit and a second light-emitting unit which are arranged in parallel atintervals. The first light-emitting unit and the second light-emitting unit are arranged in parallel at intervals, so that the organic electroluminescent device can be directly connected into external alternating current, energy loss caused by conversion of the alternating current into direct current can be avoided, and the light-emitting efficiency of the device can be improved. The whole organic electroluminescent device can be light and thin.

Description

technical field [0001] The invention relates to the display field, in particular to an organic electroluminescent device driven by alternating current. Background technique [0002] Because organic light-emitting compounds have the characteristics of adjustable light color, high luminous efficiency and low cost, organic electroluminescent devices (Organic EL) have great potential. Among them, the organic light-emitting diode (OLED) is the most typical example, and has been widely used in full-color displays and flat lighting sources. However, the characteristic of diodes is that they must be driven under direct current, and converting the alternating current in daily household life into direct current will cause unavoidable energy loss in the first place. [0003] Therefore, it is necessary to provide an organic electroluminescent device driven by alternating current to overcome the problems in the prior art. Contents of the invention [0004] The object of the present i...
