Abstract

The present application discloses an OLED light-emitting device and an OLED display screen. The OLED light-emitting device includes: an organic light-emitting layer, a first electrode layer, a variable refractive index layer, and a second electrode layer that are stacked, wherein the first electrode layer , the variable refractive index layer and the second electrode layer are arranged on the same side of the organic light-emitting layer; the refractive index of the variable refractive index layer can be between the first electrode layer and the second electrode layer changes under the action of a voltage difference. Since the refractive index of the variable refractive index layer can be changed under the action of the voltage difference between the first electrode layer and the second electrode layer, by adjusting the Voltage, to achieve the purpose of adjusting the wavelength of the outgoing light emitted by the OLED light-emitting device, which makes the color of the light emitted by the OLED light-emitting device controllable, which in turn can make the different display areas of the display screen display the same color consistently and uniformly, improving the color of the display screen display effect.

Description

technical field [0001] The embodiments of the present application relate to the technical field of display screen manufacturing, and in particular, to an OLED light-emitting device and an OLED display screen. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) light-emitting devices are widely used in the manufacture of display screens due to their advantages of self-illumination, high contrast and low power consumption. According to different light emitting positions, OLED light-emitting devices can be divided into two types: bottom emission type (BOLED) and top emission type (TOLED). [0003] For TOLED, since the light is emitted from the top of the light-emitting device, the color of the emitted light is not affected by the thickness of the light-emitting device itself, and it has a high aperture ratio and a good display effect. However, for BOLED, due to the influence of the thickness of the light-emitting device itself, there...
