Abstract

The invention discloses a perovskite light-emitting film layer, a preparation method thereof, and a display panel. The perovskite light-emitting film layer comprises a substrate and a perovskite film layer. The preparation method of the perovskite light-emitting film layer includes providing a substrate and forming a patterned regular light-emitting structure on the upper surface of the substrate. The technical effect of the present invention is that, through the induction treatment of the block copolymer, the spontaneous patterning of the block copolymer film layer is realized, and on this basis, the patterning of the perovskite film layer is realized, and the perovskite film layer is realized. Precise patterning.

Description

technical field

[0001] The invention relates to the field of display, in particular to a perovskite light-emitting film layer, a preparation method thereof, and a display panel. Background technique

[0002] Benefiting from excellent properties such as high carrier mobility, tunable band gap, adaptable flexible process, especially simple processing technology and low cost, perovskite materials show great application prospects in the field of optoelectronic devices. In particular, perovskite materials exhibit high luminous efficiency, narrow emission, and can cover the full spectral range of visible light, making them promising for luminescence-based applications such as high-end displays, anti-counterfeiting labels, flexible electronic devices, etc.

[0003] Precise patterning of perovskite thin layers is a crucial step that cannot be skipped from the excellent properties of the material to the applicable devices. For example, for display applications, the perovskite film l...
