Abstract: The disclosure provides an ink jet printing apparatus. The ink jet printing apparatus includes a support base configured to support the to-be-processed substrate; and a solvent adjusting mechanism, configured to supply a dummy region of the to-be-processed substrate on the support base with a first solvent that is same as a solvent in an ink and adjust a solvent atmosphere of the dummy region of the to-be-processed substrate on the support base, to make the solvent atmosphere of the dummy region of the to-be-processed substrate and that of a center region of the to-be-processed substrate reach a predetermined condition. The solvent adjusting mechanism is arranged on the support base.

Abstract: The present disclosure provides an inkjet printing device includes a first sprayer and a second sprayer; a first alignment unit configured to align the first sprayer to be above a display region of a display substrate; a second alignment unit configured to align the second sprayer to be above a peripheral region of the display substrate, the peripheral region surrounding the display region; a control unit configured to control the first sprayer to spray a solution toward the display region of the display substrate and control the second sprayer to spray a second solvent toward the peripheral region of the display substrate, the solution being obtained by dissolving a film-forming material in a first solvent; and an evaporation unit configured to evaporate the first solvent and the second solvent so as to form a film at the display region of the display substrate.

Abstract: The present invention provides a mask plate, a method for processing an organic layer and a method for fabricating an organic light-emitting diode display substrate. The mask plate comprises a light transmitting region and a light shading region. The light transmitting region corresponds to a region of an organic layer to be removed. The light transmitting region is provided with a photothermal conversion material for converting light energy into heat energy. The light shading region is provided with a light blocking layer for blocking transmission of light. The mask plate is suitable for processing an organic layer and particularly suitable for forming an auxiliary via hole in an organic light-emitting layer of an organic light-emitting diode display substrate.

Abstract: The present disclosure provides a magnetic device and a vapor deposition device. The magnetic device is configured to adsorb a metal mask in the vapor deposition device, including: a metal plate; an electromagnet array including a plurality of electromagnets; each of the electromagnets being inserted in the metal plate; a power supply module configured to supply a current; a control module configured to, when adsorbing the metal mask during a vapor deposition process, control the power supply module to supply a direct current to all or some of the plurality of electromagnets and control a direction and a size of the direct current by sending a first control signal to the power supply module.

Abstract: Embodiments of the present invention disclose a bended liquid crystal display and a manufacturing method and apparatus therefore. The method comprises: preparing an array substrate and a color filter substrate with flat glass sheets having different thermal expansion coefficients; applying adhesive sealant at edges of surfaces of the array substrate and/or the color filter substrate; heating the array substrate and the color filter substrate, and binding the expanded array substrate and color filter substrate together, to form an assembled substrate; and cooling the assembled substrate and forming a bended assembled substrate having a degree of curvature. The bended liquid crystal display has a better stability, and has no variation in its degree of curvature over service time.
