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 comprises the steps of providing the substrate and forming a patterned regular light-emitting structure on the upper surface ofthe substrate. The method has the technical effects that the spontaneous patterning of the block copolymer film layer is realized through the induction treatment of the block copolymer; and on the basis, the patterning of the perovskite film layer is realized, and the precise patterning of the perovskite film layer is realized.

Description

technical field

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

[0002] Benefiting from excellent properties such as high carrier mobility, adjustable 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 spectrum of visible light, making them promising for applications based on luminescence, such as high-end displays, anti-counterfeiting labels, and flexible electronic devices.

[0003] From the excellent performance of materials to applicable devices, the precise patterning of perovskite thin layers is a critical step that cannot be skipped. For example, for display applications, the perovskite film layer n...
