Organic luminescence display panel and device

Abstract

The embodiment of the invention discloses an organic luminescence display panel and a device; the organic luminescence display panel comprises a first electrode, a cavity injection layer, a luminescent layer and a second electrode stacked in order; the cavity injection layer comprises comprise an organic material and a conductive metal oxide, or the cavity injection layer is formed by stacking an organic material film with a conductive metal oxide film. The cavity injection layer comprises comprise the organic material and the conductive metal oxide, or the cavity injection layer is formed by stacking the organic material film with the conductive metal oxide film, thus solving the problems that the interfacial energy barrier between the cavity injection layer and the anode of an existing organic luminescence display panel is overly high, and so the organic luminescence display panel is low in performance; the organic luminescence display panel of the invention can reduce the interfacial energy barrier between the cavity injection layer and the anode of the organic luminescence display panel, thus improving the cavity injection ability, and improving the organic luminescence display panel performance.

Description

technical field [0001] Embodiments of the present invention relate to organic light emitting display technology, and in particular to an organic light emitting display panel and device. Background technique [0002] Organic light emitting display (Organic light emitting display), due to its technical advantages such as no need for backlight, high contrast, thin thickness, wide viewing angle, and fast response speed, has become one of the key directions for the development of the display industry. [0003] Existing organic light-emitting display panels include: a cathode, an electron transport layer, a light-emitting layer, a hole transport layer, an anode and a substrate. When working, a bias voltage is applied between the anode and the cathode of the organic light-emitting display panel, and the holes and electrons break through the interface energy barrier and migrate from the hole transport layer and the electron transport layer to the light-emitting layer respectively. O...

Problems solved by technology

However, in current organic light-emitting display panels, because the interface energy barrier between the hole injection layer and the anode is too high, the hole injection ability is low, which will make the performance of the organic light-emitting display panel poor.
