Problems solved by technology

This method has a low transmittance due to the addition of a color filter, and the color displayed after being filtered by the filter is not as pure as the RGB three primary colors to achieve full-color display, which affects the color gamut and reduces the display effect.

Abstract

The invention provides a display panel and a display device, relates to the field of display technology, and solves the existing problem of reducing display brightness by implementing color display through a color filter. A display panel, comprising a plurality of pixels, each of which at least includes a first sub-pixel, a second sub-pixel and a third sub-pixel, each of which includes a light-emitting element that emits green light; the first sub-pixel The pixel also includes a first up-conversion material layer on the first light-emitting side of its light-emitting element, and the first sub-pixel emits light of the first color on the first light-emitting side; The light output side also includes a first down conversion material layer, the second sub-pixel emits light of a second color on its first light output side; the third sub-pixel emits green light on its first light output side; wherein the green light , the first color light and the second color light are three primary color lights.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The existing color display is generally realized by white light color and color filter, such as figure 1 As shown, taking an OLEDOrganic Light-Emitting Diode (Organic Light-Emitting Diode) display panel as an example, the display panel includes a base substrate 10 and a plurality of cathodes 11 and anodes 13 formed on the base substrate 10, and between the cathodes 11 and the anodes 13. Between the luminescent material layer 12. in, figure 1 In the above, a pixel on a display panel includes three sub-pixels as an example, and the light-emitting material layer corresponding to each sub-pixel emits white light (W). The display panel also includes a color filter layer 14 on the light-emitting side. The white light emitted by the luminescent material layer is filtered by the color filter and then converte...
