Document Type and Number:
WIPO Patent Application WO/2022/246690
Kind Code:
A1
Abstract:
Provided in the present disclosure is a display panel, comprising a light-emitting layer, a transparent spacer layer on the light-emitting layer, and a wavelength conversion layer on the transparent spacer layer. The problem of color crossing in a wavelength-conversion-type display panel is at least partially solved by controlling, according to the brightness change rates of wavelength conversion units of adjacent pixels and a light path characteristic of the transparent spacer layer, the intensity ratio of light reaching wavelength conversion units of adjacent sub-pixels to be within a certain limit.
