Organic light emitting display panel and organic light emitting display device

Abstract

According to the embodiments of the invention, an organic light emitting display panel and organic light emitting display device are provided wherein the organic light emitting display panel comprises a first substrate; a first electrode layer arranged on the first substrate and comprising a plurality of first electrodes; a first hole transport layer arranged on one side surface of the substrate deviating from the first electrode layer and comprising a plurality of hole transport units arranged at positions corresponding to the plurality of the first electrodes respectively; a plurality of light emitting elements arranged at positions corresponding to the plurality of hole transport units, disposed on one side surface of the first electrode layer deviating from the first hole transport layer and comprising m colors so that the mobility of the hole transport units corresponding to the light emitting elements in any two colors varies from each other; and a second electrode layer arranged on one side surface of the first hole transport layer deviating from the plurality of the light emitting elements. According to the embodiments of the invention, the transverse current across the hole is reduced so as to achieve the effect of reducing the sub-pixels for dim lightings.

Description

technical field [0001] Embodiments of the present invention relate to organic light emitting diode technology, and in particular to an organic light emitting display panel and an organic light emitting display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel is a self-luminous display device with organic thin film as illuminant, which has the advantages of ultra-thin, high brightness, high luminous efficiency and good shock resistance. In an organic light emitting display panel, a pixel defining layer is usually used to define each sub-pixel area. In order to improve the encapsulation effect of each sub-pixel, a spacer can also be provided on the pixel defining layer between any two adjacent sub-pixels. [0003] However, the organic light-emitting display panel manufactured by the prior art has the phenomenon of stealing light from adjacent sub-pixels. Such as figure 1 Shown is a structure of an organic l...
