Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application. Where possible, the same or similar parts will be given the same reference numerals in the drawings.

[0021] At present, the film-forming methods of the functional film layer in the display panel mainly include evaporation method and inkjet printing method. Film formation by evaporation is relatively mature in the preparation of small-size display panels, while film formation by inkjet printing is considered to be the most suitable method for large-size display panels due to its fast film formatio...

Abstract

The invention discloses a display panel and its preparation method, a display panel and an inkjet printing device. The display panel includes a substrate and a plurality of functional film layers arranged on the substrate, wherein the plurality of functional film layers include At least one positioning function film layer, the positioning function film layer includes a first area and a second area located around the first area, the positioning function film layer located in the first area and the positioning function film layer located in the second area The light reflectance and / or thickness and / or resistance of the positioning functional film layers are different, and the projections of the first region and the second region of each positioning functional film layer on the substrate overlap respectively. The structure of the display panel can help the nozzle to be positioned on the positioning functional film layer during the preparation of the display panel by the inkjet printing process, and has a better printing effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a preparation method thereof, and an inkjet printing device. Background technique [0002] At present, the film-forming methods of the functional film layer in the display panel mainly include evaporation method and inkjet printing method. Evaporation is relatively mature in the preparation of small-sized display panels, but it requires the use of FMM (high-precision metal mask), which is complicated in process and high in cost, while inkjet printing is simple in process and low in cost. However, there are problems that the printing position of the material to be printed by inkjet is deviated and the thickness of the functional film layer is not uniform. Contents of the invention [0003] Embodiments of the present invention are dedicated to providing a display panel, a manufacturing method thereof, and an inkjet printing device, so as to solve the problems o...
