Abstract

The invention discloses an array substrate, an organic light-emitting diode (OLED) display panel, a display device and an inkjet printing method. As a virtual electrode in one-to-one correspondence with each anode layer is arranged and a reference line in corresponding connection with each virtual electrode is also arranged, when an inkjet printing method is adopted to spray ink drops on the anodelayer, charges can be applied to the virtual electrode through the reference line, charges of the virtual electrode and the charges in the ink drops in a corresponding sprayer have opposite polarities, the principle of mutual attraction between charges of different polarities is used to enable the ink drops in the sprayer to be absorbed to a to-be-reached pixel anode layer, and the problem of display cross color caused by organic ink drop position offset existing in the prior art can be solved. Besides, voltage is provided for the virtual electrode through the reference line, the realizationprocess is simple; and as the virtual electrode and the anode layer are mutually insulated, setting of the virtual electrode and the reference line does not generate influences on display of a subsequently-formed OLED panel.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to an array substrate, an organic electroluminescence display panel, a display device and an inkjet printing method. Background technique

[0002] Organic light-emitting diodes (OLED) is a display device that is packaged and molded using organic materials. It has the advantages of low operating voltage, fast response speed, high luminous efficiency, wide viewing angle and wide operating temperature. It is beneficial to the thinning, low power consumption and curved surface design of the display device.

[0003] In the prior art, the organic film layers in OLED organic electroluminescent devices are generally prepared by inkjet printing. Use the nozzle to spray the organic ink droplet onto the anode layer of the corresponding pixel, but during the spraying process, the position of the organic ink droplet is easily shifted, causing the organic ink droplet to be sprayed onto the anod...
