White organic light-emitting diode display panel

Abstract

The invention relates to the field of organic light-emitting diode display, and discloses a white organic light-emitting diode display panel. The white organic light-emitting diode display panel comprises a substrate, a package substrate, a light-emitting functional layer, an emission negative electrode layer and a color filtering layer, wherein the substrate and the package substrate are arrangedopposite to each other, the light-emitting functional layer is arranged between the package substrate and the substrate, the emission negative electrode layer is arranged at one side, facing the package substrate, of the light-emitting functional layer, the color filtering layer is arranged at one side, deviating from the emission negative electrode layer, of the light-emitting layer, the color filtering layer comprises a first filtering layer, a second filtering layer and a third filtering layer, the first filtering layer is used for transmitting blue light and green light and reflecting redlight, the second filtering layer is used for transmitting the red light and the green light and reflecting the blue light, and the third filtering layer is used for transmitting the red light and the blue light and reflecting the green light. In the white organic light-emitting diode display panel disclosed by the invention, the first filtering layer, the second filtering layer and the third filtering layer are arranged, the whole light ray transmittance is improved, so that the light efficiency loss is reduced.

Description

technical field [0001] The present application relates to the field of organic light emitting diode displays, in particular to a white light organic light emitting diode display panel. Background technique [0002] In the prior art, part of the light from the light-emitting functional layer of the traditional bottom-emission white organic light-emitting diode display panel will be absorbed by the color film, resulting in loss of light efficiency. Taking the red sub-pixel area as an example, the light emitted by the light-emitting functional layer to the color film side Only the red light will pass through the red color film layer, while the blue light and green light will be absorbed by the red color film layer; and after the light emitted by the light-emitting functional layer to the reflective cathode layer is reflected, the blue light and green light will be reflected. Green light is also still absorbed by the red color film layer. Therefore, how to reduce the light effi...
