Problems solved by technology

However, in the prior art, part of the short-wavelength light cannot be irradiated on the quantum dots, resulting in a low light conversion rate, and part of the long-wavelength light excited by the light conversion layer cannot be emitted to the outside of the display panel, resulting in a low light-extraction rate.

Abstract

The invention discloses a display panel, and belongs to the technical field of display. The display panel comprises a light emitting layer, a light conversion layer and a plurality of spacers, wherein the light-emitting layer can emit light with a first wavelength; the light conversion layer is located on the light emitting side of the light emitting layer and comprises a plurality of conversion units arranged at intervals, and at least part of the conversion units can excite second wavelength light under the action of the short wavelength light; wherein the wavelength of the first wavelength light is smaller than that of the second wavelength light; one spacer is arranged around the periphery of one conversion unit, and the side wall, facing the conversion unit, of the spacer is a reflecting surface. And when irradiating the reflecting surface, short-wavelength light rays emitted by the light-emitting layer are reflected into the corresponding conversion units, so that more long-wavelength light rays are excited, and the light conversion rate is improved. And when the emergent light of the conversion unit irradiates the reflecting surface, the emergent light is reflected to the outside of the display panel, so that the light extraction rate is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] With the development of display technology, OLED display will gradually replace other display technologies and become the next generation display technology, among which quantum dot OLED display is developing rapidly. Quantum dot OLED display panels need to use a light conversion layer containing quantum dots to convert short-wavelength light into long-wavelength light to obtain various colors of light required for display. However, in the prior art, part of the short-wavelength light cannot be irradiated on the quantum dots, resulting in a low light conversion rate, and part of the long-wavelength light excited by the light conversion layer cannot be emitted to the outside of the display panel, resulting in a low light-extraction rate. Contents of the invention [0003] The technical problem mainly solved by the presen...
