Abstract

The invention provides an organic light-emitting diode device and a display device. The display device comprises the organic light-emitting diode device; and the organic light-emitting diode device comprises an anode layer, a reflective layer, a light-emitting layer and a cathode layer which are sequentially stacked from bottom to top. According to the organic light-emitting diode device and the display device of the invention, the reflective layer made of a nanoscale reflective material is added and is used for reflecting light propagated towards one side of the anode layer of the light-emitting layer, so that the light of the light-emitting layer is completely emitted from one side of the cathode layer; and therefore, light-emitting efficiency is improved, display brightness is improved,and product thickness is reduced. The energy consumption of the organic light-emitting diode device is lower when that of the organic light-emitting diode device used in an outdoor strong light environment, and the service life of the organic light-emitting diode device is prolonged.

Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting diode device and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is also called organic electro-laser display and organic light-emitting semiconductor. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast, low power consumption, and extremely high response speed. However, due to the immature technology, the yield rate of the product is low and the cost is high. Therefore, in terms of price, it is temporarily unable to form an effective competition with the liquid crystal display panel. [0003] Such as figure 1 It is the basic structure of an existing organic light emitting diode device. The organic light emitting diode device 90 is made of a thin and transparent indium tin oxide (ITO) with semiconducting properties as the anode 91, which is connected to the positive...
