Abstract

The present invention provides a display panel. At the opening of the first groove, the first sealing inorganic layer seals the first groove to form a first cavity. When inkjet printing, when the organic material flows to the first corner of the first barrier wall, due to the action of the first cavity inside the first barrier wall, the excess organic material will be absorbed into the first cavity through the first through hole In the capillary channel of the body, the overflow of the organic material is effectively avoided, and at the same time, the organic material filled in the first cavity effectively relieves the stress at the first retaining wall and enhances the bending resistance of the panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is considered to be a new generation of display technology due to its characteristics of realizing flexible display, and has broad application prospects. However, OLED devices are particularly sensitive to water and oxygen. After water and oxygen infiltrate, metal electrodes and organic light-emitting materials are easily aged, which affects the service life of the device. In order to prevent the device from being damaged and achieve the effect of flexible display, the method of thin-film encapsulation (TFE) is generally used now, that is, the metal electrode and the organic light-emitting material are encapsulated in an alternating way of inorganic / organic multilayer thin films. To achieve the purpose of blocking water and oxygen and improve the service life of the ...
