Abstract

The invention provides a light emitting element, which comprises a transparent substrate, a first electrode layer, a second electrode layer, a light-emitting layer and a light wavelength adjusting film. The light-emitting layer comprises a first surface and a second surface opposite to each other. The first electrode layer is arranged on the first surface and the first electrode layer is a transparent electrode layer. The second electrode layer is arranged opposite to the first electrode layer. The light-emitting layer is arranged between the first electrode layer and the second electrode layer. The light wavelength adjusting film comprises a transparent layer and a plurality of fluorescent particles. The transparent layer comprises a light incident surface and a light exiting surface opposite to each other. The light incident surface is connected to the second surface. The light exiting surface is in contact with the outside air. The fluorescent particles are disposed in the transparent layer. The light-emitting element has better optical performance.

Description

technical field [0001] The present invention relates to a semiconductor electronic element, and in particular to a light emitting element. Background technique [0002] Organic light emitting diodes have the advantages of small size, long service life, and fast response time. In recent years, with the continuous improvement of organic light emitting diode (OLED) technology, organic light emitting diodes have been gradually applied in various Fields, such as flat light source or flat display, etc. [0003] In order to improve the color rendering index (CRI) of the organic light emitting diode and the performance of the index color R9, the known technology achieves the above purpose by adding a variety of dopant materials. [0004] However, if there are three or more types of doping materials, it will be difficult to adjust these doping materials so that the luminous spectrum and luminous efficiency of the organic light-emitting diode meet the requirements, and the organic li...
