  • Patent number: 8402916
    Abstract: A deposition mask that includes a mask sheet and a frame to support the perimeter of the mask sheet. The frame includes a contact surface that is attached to the mask sheet, and a non-contact surface that faces and is spaced apart from the mask sheet, the non-contact portion extends from the contact portion, to an opening formed in the center of the frame. The non-contact portion may form an acute angle, with respect to the plane of the mask sheet.

  • Patent number: 8350468
    Abstract: Embodiments of the present disclosure provide an organic electroluminescence display device. The display device may include a set of multi-directional spacers that are interposed between the pixels of the display. In one embodiment, the spacers are positioned in both lengthwise and crosswise directions. In another embodiment, the spacers include a first portion that is extends lengthwise between pixels and one or more portions that extend laterally from the first portion between pixels. In yet another embodiment, the spacers include portions that extend in multiple directions between pixels. The spacers may substantially surround each of the pixels and may serve as a boundary, for example, that prevents organic material for one pixel from being incorrectly deposited in another pixel. The spacers can be configured as a support structure, such as, for a metal mask during fabrication of the display device.
