Embodiment 1

[0039] Such as figure 1 , figure 2 As shown, an inkjet printing device 100 is provided in an embodiment of the present invention, which includes a loading platform 10 , a cooling mechanism, and a spray head 70 . The loading platform 10 has a working surface for loading substrates. The spray head 70 is disposed above the substrate for inkjet printing on the substrate.

[0040] The cooling mechanism is arranged above the loading platform 10 and includes a cooling plate 20 , an up and down telescopic mechanism 30 and a cooling medium. The thickness of the cooling plate 20 is 10mm-80mm, and its interior is hollow to form a cavity 21 structure. Such as Figure 5 as well as Image 6 As shown, the cavity may be square or oval. The cooling medium is filled in the cavity, which can be gas or liquid. The temperature of the cooling medium is 0°C-30°C. The cooling plate 20 realizes the cooling function through the cooling medium.

Abstract

The invention provides an ink-jet printing device and method. The ink-jet printing device comprises a loading platform, a cooling mechanism and nozzles; the loading platform comprises a working tabletop and is used for loading base plates; the cooling mechanism is arranged above the base plates; and the nozzles are arranged above the base plates and are used for performing ink-jet printing on thebase plates. The cooling mechanism is added to the ink-jet printing device, so that the volatilization speed of ink is reduced, and the problems that the yield of products is affected due to volatilization of the ink, the service life of the products is short and the like in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet printing device and an inkjet printing method. Background technique [0002] OLED, and Organic Light-Emitting Diode (Organic Light-Emitting Diode), have become Organic Electroluminescence Display (OELD), which has self-illumination, fast response speed, large viewing angle, low energy consumption, light weight, thin thickness, and structure Simple, flexible, wide operating temperature range, low cost and other advantages, so it has been optimistic about the industry, is considered to be the most promising new generation of display technology. [0003] At present, the development trend of organic light-emitting diode display devices is gradually carried out in the direction of inkjet printing. In the inkjet printing process, there are processes such as drying, baking, and printing. In an organic light emitting diode display device, there are at least three film ...
