Encapsulation method for display panel, display panel and display device

Abstract

The invention discloses an encapsulation method for a display panel, a display panel and a display device. The encapsulation method comprises: a main display panel body is provided, wherein the main display panel body includes an external circuit arranged in a non-display area; a protection layer at least covering the part of the external circuit is formed; an encapsulation layer for encapsulatingthe main display panel body is formed and the encapsulation layer is patterned; and the protection layer is removed. According to the encapsulation method, the protection layer is formed before forming the encapsulation layer to protect the part of external circuit and then the protection layer is removed after forming the encapsulation layer, so that a metal mask plate for shielding the externalcircuit is saved; the protection layer does not affect the making of an inorganic layer, so that a phenomenon of non-uniform thickness of the inorganic layer is avoided; reservation of a region thatmay have the non-uniform thickness in frame design is avoided; and thus the frame design is reduced and the narrow-frame design is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a packaging method of a display panel, a display panel and a display device. Background technique [0002] Currently, a bendable display can be realized through a liquid crystal display panel (Liquid Crystal Display, LCD) and an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel. Affected by factors such as lightness, thinness, and ease of bending of flexible displays, there are many demands for new bendable terminal devices. The bending of the flexible display product may be the bending of the display element, or the bending of the control circuit area of ​​the display element. [0003] Benefiting from the characteristics of self-luminescence, OLED displays fabricated on flexible substrates are easier to achieve bendable displays with smaller bending radii. Therefore, the fabrication of OLED display panels including flexible substrates has attract...
