Problems solved by technology

However, the increase of the transmittance of the top electrode means the reduction of the reflectivity, which weakens the effect of microcavity interference and reduces the color saturation of the OLED, and in the process of preparing the ITO top electrode (highly transparent electrode) by sputtering, The high-energy particles produced by sputtering can also damage the functional layers of the device

Abstract

The invention relates to an organic light-emitting diode device, a manufacturing method thereof and a display panel. The organic light-emitting diode device comprises a substrate, an anode layer, an organic light-emitting layer and a cathode layer which are sequentially stacked, and a silver nanowire scattering film is formed on the side, away from the organic light-emitting layer, of the cathode layer. The silver nanowire scattering film can scatter the light which is generated by the organic light-emitting layer and is emitted by the cathode layer to different directions, so that the angle dependence of the organic light-emitting diode is reduced, and the display quality of the organic light-emitting diode is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic light emitting diode device, a manufacturing method thereof, and a display panel. Background technique [0002] At present, the full width at half maximum of the emission spectrum of an organic light emitting diode (OLED) is generally 50 to 80 nm, and the spectrum is asymmetrical, and the color saturation of the device is low, which seriously reduces the display quality. To improve the color saturation of OLEDs, a top-emitting OLED device was fabricated using a reflective bottom electrode and a translucent top electrode. In this structure, the reflected light from the bottom electrode and the top electrode interfere with each other, and by adjusting the cavity length and the resonance of the emission wavelength, the device efficiency can be effectively enhanced and the emission spectrum can be narrowed. However, top-emitting OLED devices have severe angle d...
