Abstract

The invention provides a membrane layer, luminous device, membrane layer treatment method, device and system.This membrane layer treatment method includes steps: S1, set the ink on the base to form a dry membrane layer. Among them, the ink includes the first solvent and soluble; S3, a decentralized second solvent on the above plane of the dry membrane layer isFor small drops, the small solution is formed by the second solvent by ultrasonic vibration. The solubility of the solubility of the second solvent is greater than the solubility of the solubility of the first solvent, and at least some small liquid droplets enter the dry membrane layer.This membrane layer treatment method slows the rate of drying the membrane to form the dry membrane layer, increases the volatile uniformity of the solvent, and effectively improves the uniformity of the membrane layer of the inkjet printing.The solvent volatilization rate in the membrane layer of the pixel is different or too fast, which causes uneven appearance of the film.

Description

technical field [0001] The present invention relates to the technical field of film layer preparation, in particular to a film layer, a light-emitting device, a film layer processing method, device and system. Background technique [0002] In the preparation of PLED (English: Polymer Light-Emitting Diode, polymer light-emitting diode), OLED (organic light-emitting diode) and QLED (quantum dot light-emitting diode) display or lighting devices, inkjet printing technology is usually used to form red and green , blue three primary color light-emitting pixels. The pre-patterned ITO (Indium Tin Oxide) substrate is adsorbed on the printing platform, and various materials (including functional layer materials, and red, green, and blue light-emitting materials) dissolved in the solvent ) solution is sprayed in the sub-pixel pits on the substrate to form red, green and blue three-primary-color light-emitting pixels. Then, excess solvent in the film layer is removed through a subsequ...
