Abstract
The invention provides a mask. The mask comprises a first surface and a second surface opposite to the first surface. A plurality of through holes are formed in the mask. Each through hole penetratesthrough the first surface and the second surface. The first surface and the second surface are coated with super-hydrophobic materials correspondingly. The mask provided by the invention is applied tothe vacuum drying device, solvent droplets adhering to the top of a cavity of the vacuum drying device can be prevented from dripping onto a panel when the vacuum drying device is used for performingvacuum drying on the panel with ink printed thereon, the situation that a film formed on the panel is not uniform is avoided, and the display effect of the display panel is improved. The invention further provides a manufacturing method of the mask, a composite mask provided with multiple masks, and the vacuum drying device provided with the masks or the composite mask.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a mask and its manufacturing method, a composite mask and a vacuum drying device. Background technique [0002] In the production process of the display panel, the ink containing the organic functional material is usually printed on the predetermined position on the panel by means of Ink Jet Printing (Ink Jet Print, IJP), and then the printing is carried out using a vacuum drying (Vacuum Dry, VCD) device. The panel with the ink is vacuum-dried to volatilize the solvent in the ink and form a thin film containing only solute (ie organic functional material) on the panel. [0003] During the vacuum drying process, the gas generated when the solvent volatilizes is easily converted into liquid droplets that adhere to the chamber wall of the vacuum drying device, and the liquid droplets adhered to the chamber wall will drip onto the panel under certain conditions, causing the panel T...
