  • Patent number: 10403819
    Abstract: A pixel define layer and manufacturing method thereof and the related light emitting display are disclosed. The pixel define layer is arranged on a conductive layer of a substrate and comprises a base film layer. The base film layer has a plurality of openings each of which corresponds to a light-emitting region of a sub-pixel unit. A spacing base body is formed between the adjacent openings. An upper surface of each spacing base body is coated with a hydrophobic quantum dot material and a side wall of each opening is coated with a hydrophilic quantum dot material. With the pixel define layer and manufacturing method thereof and the related light emitting display according to embodiments of the disclosure, the ink within the sub-pixel would not ooze to the outside of the sub-pixel to result in color mixture between the adjacent sub-pixels, and the light emitting region within the pixel would not be decreased. By selecting suitable quantum dot materials, the photochromic efficiency can be improved.

  • Patent number: 10395929
    Abstract: Small size chip handling and electronic component integration are accomplished using handle fixturing to transfer die or other electronic components from a full area array to a targeted array. Area array dicing of a thinned device wafer on a handle wafer/panel may be followed by selective or non-selective de-bonding of targeted die or electronic components from the handle wafer and optional attachment to a carrier such as a transfer head or tape. Alignment fiducials may facilitate precision alignment of the transfer head or tape to the device wafer and subsequently to the targeted array. Alternatively, the dies or other electronic elements are transferred selectively from either a carrier or the device wafer to the targeted array.
