Problems solved by technology

Although the microcavity effect strengthens the light of a specific wavelength and improves the luminous intensity of the display panel, the resonance wavelength of each angle in the microcavity effect is different, which aggravates the color shift phenomenon of the display panel. Therefore, top emission organic light emitting diodes The problem of color shift at different viewing angles of the display panel is more serious
[0005] For this reason, a new organic light emitting diode display panel and its forming method are needed to solve the color shift problem of the organic light emitting diode display panel

Abstract

The invention provides an organic light-emitting diode display panel and a forming method thereof. The organic light-emitting diode display panel comprises a substrate base plate and a packaging cover plate which are arranged opposite to each other, an organic light-emitting diode which is located between the substrate base plate and the packaging cover plate, and a light scattering film layer which is located at least one of the inner surface or the outer surface of the packaging cover plate and is capable of conducting scattering on rays emitted by the organic light-emitting diode. Due to the fact that the light scattering film layer can conduct scattering on the rays emitted by the organic light-emitting diode, after the rays are scattered, the scattered rays are emitted from different directions, a looker can see the scattered rays when looking the organic light-emitting diode display panel from different angles, the looker can not see color deviation, and the color-bias phenomenon is eliminated.

Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting diode display panel and a forming method thereof. Background technique [0002] The organic light emitting diode (OLED) display panel is a self-luminous display panel, which has the advantages of short response time and wide viewing angle range. [0003] The light-emitting layer of the OLED display panel is an organic emitting layer (organic emitting layer, EML), and the organic emitting layer is usually covered with other film layers, so the light generated by the organic light-emitting layer needs to pass through other film layers to enter the atmosphere outside the display. When the light enters the atmosphere through other film layers, it will be refracted. The longer the wavelength of the light, the smaller the refraction angle. Therefore, the refraction angle of red light is smaller than the blue light refraction angle, resulting in the color seen by the human ...
