Problems solved by technology

[0004] However, the thin film color of the organic layer in the thin film encapsulation structure in the prior art is yellowish, and the blue light transmittance is poor. Because the OLED device itself has the problem of low luminous efficiency of blue light, after the thin film encapsulation, after the organic layer thin film cut, the transmittance of blue light is greatly reduced

Abstract

The invention discloses an OLED panel, a preparation method of the OLED panel and a display device. The OLED panel includes a substrate; an array of light-emitting devices located on the substrate; a thin-film encapsulation layer that encapsulates the array of light-emitting devices, and the thin-film encapsulation layer includes at least one organic thin film layer and at least one inorganic thin film layer; at least one of the organic The film layer is an oxygen-fluorine organic film layer. The technical solution provided by the present invention uses an oxygen-fluorine-containing organic thin film layer to replace the organic thin film layer in the prior art, which can improve the light transmittance of the thin film encapsulation layer, especially the light transmittance of the blue light wavelength band, so that the thin film encapsulation layer reduces the Light transmission loss to light emitting devices.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of OLED packaging, and in particular to an OLED panel, a method for manufacturing the OLED panel, and a display device. Background technique [0002] The optical materials and electrodes in OLED devices are very sensitive to water vapor and oxygen, and the penetration of water and oxygen will greatly reduce the life of OLED devices. In order to meet the requirements of commercialization for the service life and stability of OLED devices, OLED devices require packaging very high. Therefore, encapsulation is very important in OLED panel fabrication. [0003] Traditional encapsulation usually adopts cover plate encapsulation technology, coating the encapsulation glass with a UV-curable sealant, or applying a sealant and filling it with a desiccant. After the sealant is cured, it can provide a relatively airtight environment for the OLED device, thereby isolating water. Oxygen enters....
