OLED (Organic Light Emitting Diode) display panel and fabrication method

Abstract

The invention discloses an OLED (Organic Light Emitting Diode) display panel and a fabrication method. The OLED display panel comprises a substrate, an OLED luminous device, a package layer and a light scattering layer, wherein the OLED luminous device is arranged on the substrate, the package layer is packaged outside the OLED luminous device, the OLED luminous device at least comprises a red luminous device, a green luminous device and a blue luminous device, the blue luminous device adopts an optical microcavity structure, and the light scattering layer is arranged at a light giving-out side of the blue luminous device. A blue luminous device region of the OLED display panel adopts the optimal microcavity structure, thus, the color purity and the photoelectrical performance of a blue sub-pixel are improved; meanwhile, the light scattering layer is further arranged at the light giving-out side, the light giving-out efficiency of the blue sub-pixel is further improved, namely, the photoelectrical performance and the stability of the blue sub-pixel are further improved; and meanwhile, the light scattering layer can be used for effectively scattering light emitted from the blue luminous device, and thus, the problem of a visual angle caused by the adoption of the optical microcavity structure can be effectively solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a manufacturing method. Background technique [0002] With the development of display panels towards thinner, lower power consumption, and portability, the new generation of display technologies represented by organic light-emitting diodes (OLEDs) has attracted more and more attention. Compared with LCD display technology, OLED has the advantages of thinness, low power consumption, low driving voltage, better viewing angle and contrast, and faster response speed. [0003] At present, OLED display panels have been commercialized and widely used in display fields such as mobile phones, tablet computers, and televisions. However, there are still some problems, especially the chromatographic purity, performance and stability of blue light-emitting devices, which are key factors that limit the development of OLED display panels. At present, there are some ...
