A deposition mask apparatus including a frame, a supporter including a plurality of supporting members fixed to the frame, and a deposition mask fixed to the frame is provided. The plurality of supporting members include at least a first supporting member that is closest to an intermediate position between a third portion and a fourth portion of the frame and a second supporting member that is located closer to the third portion of the frame than the first supporting member. The first supporting member in a state of warping downward from the frame with a first warping amount supports the deposition mask from below. The second supporting member in a state of warping downward from the frame with a second warping amount that is smaller than the first warping amount supports the deposition mask from below.

A shadow mask for patterned vapor deposition of an organic light-emitting diode (OLED) material includes a ceramic membrane under tensile stress with a plurality of through-apertures forming an aperture array through which a vaporized deposition material can pass. A multilayer peripheral support is attached to a rear surface with a hollow portion beneath the aperture array. A compressively-stressed interlayer balances the tensile stress of the ceramic membrane. A shadow mask module with multiple shadow masks is also provided and includes a rigid carrier having plural windows with a shadow mask positioned in each window. To make the module, shadow mask blanks are affixed to each carrier window followed by etching of apertures and support layers. In this way extremely flat masks with precise aperture patterns are formed.

The present disclosure provides a thin-film-deposition equipment with double-shaft shielding device, which includes a reaction chamber, a carrier and a double-shaft shielding device. The double-shaft shielding device includes a first-connecting arm, a second-connecting arm, a first-shield member, a second-shield member, a first driver and a second driver. The first driver is connected to the first-shield member via the first-connecting arm, and the second driver is connected to the second-shield member via the second-connecting arm, for respectively driving and swinging the two shield members to move in opposite directions via the two connecting arms. Thereby, during a cleaning process of the thin-film-deposition equipment, the two drivers swing the two shield members toward each other into a shielding state for covering the carrier, such that to effectively prevent removed pollutants from polluting the carrier during.

A mask assembly includes a mask frame in which a first opening is defined, the mask frame including a front surface through which the first opening extends, and a deposition mask which is attached to the front surface of the mask frame and through which a plurality of second openings is defined. The mask frame includes an in which the front surface extends along a direction of gravity, the deposition mask includes an initial mask which is attached to the front surface of the mask frame in the thereof and through which the plurality of second openings is defined, and the of the mask frame having the front surface which extends along the direction of gravity disposes the first opening of the mask frame corresponding to all of the plurality of second openings of the initial mask along the direction of gravity.

The present application discloses a decorating accessory 100 for protecting a surface beneath a hung door 200, the accessory 100 comprising an elongate tray 101 having a base 102 and a pair of longitudinal edges 103, 104 raised above the base 102, the tray 101 being tapered at a first end 105.

The mask includes: a mask body provided with a shielding part configured to shield an IC region between two adjacent panels sharing a base substrate; and the shielding part includes a reinforcing portion and a thinned portion, and the thinned portion has an accommodating recess with an opening facing the base substrate to be configured to accommodate a driving IC in the IC region.

A deposition mask includes: a first surface and a second surface, in which a plurality of through-holes are formed; a pair of long side surfaces connected to the first and second surfaces, and defining a profile of the deposition mask in a longitudinal direction of the deposition mask; and a pair of short side surfaces connected to the first and second surfaces, and defining a profile of the deposition mask in a width direction of the deposition mask. The long side surface includes a first portion that is recessed inside and includes a first end portion positioned along the first surface, and a second end portion positioned along the second surface and positioned inside the first end portion. The through-hole includes a first recess formed on the first surface, and a second recess formed on the second surface and connected to the first recess through a hole connection portion.
