Abstract
The present invention provides a mask plate, the mask plate includes a first surface and a second surface opposite to each other, the mask plate is provided with a plurality of through holes, and each of the through holes passes through the first The surface and the second surface, the first surface and the second surface are coated with a superhydrophobic material. The mask plate provided by the present invention is applied in a vacuum drying device, and during the process of vacuum drying the panel printed with ink by the vacuum drying device, it can stop the dripping of solvent droplets adhering to the top of the chamber of the vacuum drying device To the panel, the unevenness of the thin film formed on the panel is avoided, and the display effect of the display panel is improved. The invention also provides a manufacturing method of the mask, a composite mask with the mask and a vacuum drying device with the mask or the composite mask.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a mask and a manufacturing method thereof, a composite mask and a vacuum drying device. Background technique [0002] In the production process of the display panel, ink containing organic functional materials is usually printed on a predetermined position on the panel by means of ink jet printing (Ink Jet Print, IJP), and then a vacuum drying (Vacuum Dry, VCD) device is used to print the ink. The panel with ink is vacuum-dried to volatilize the solvent in the ink, and a thin film containing only solute (ie, organic functional material) is formed on the panel. [0003] In the process of vacuum drying, the gas generated when the solvent volatilizes is easily converted into droplets and adheres to the cavity wall of the vacuum drying device, and the droplets adhering to the cavity wall will drip onto the panel under certain conditions, causing the panel The film formed thereon is...
