A selective quenching quantum dot layer is obtained after coating a quantum dot adhesive uniformly on a color filter layer, and the light mask is used to irradiate the quantum dot adhesive on the blue sub-pixel region. Free radicals are generated by cleaving photoinitiator and are quenching the quantum dot material directly; the method is capable of meeting requirement of high gamut, simple preparation process and low cost.

  • Patent number: 10007368
    Abstract: Different lamination methods may be used to create a touch sensor with a darkened side of metalized film facing the user. One lamination method includes laminating a metalized film to an optically clear adhesive (OCA) layer such that an edge of the metalized film including the termination pads remain un-adhered to the OCA layer. Flex-tails may be bonded to the termination pads at a later time by bending up the un-adhered edge. Anisotropic Conductive Film (ACF) may be placed on the termination pads prior to laminating the metalized films. Flex-tails may be placed onto an OCA layer in a location where the termination pads on the metalized film will be located when laminated to the OCA layer. A strip of ACF may be placed on the flex-tail pads. The flex-tails may be bonded to the termination pads of the metalized film prior to the metalized film being laminated.

  • Patent number: 9957411
    Abstract: An underfill material achieving a wide margin for mounting and a method for manufacturing a semiconductor device using the same are provided. The underfill material contains an epoxy resin, an acid anhydride, an acrylic resin, and an organic peroxide, wherein a minimum melt viscosity attainment temperature and a minimum melt viscosity obtained when melt viscosity of the underfill material is measured under a temperature increase rate condition in a range of 5 to 50° C./min are in a range of 100° C. to 150° C. and in a range of 100 to 5000 Pa·s, respectively. Since variation in the minimum melt viscosity attainment temperature measured under different temperature increase conditions is small, voidless mounting and good solder bonding properties can be achieved without strict control on the temperature profile during thermocompression bonding, and a wide margin for mounting can be achieved.

  • Patent number: 9947842
    Abstract: The present disclosure provides a method for manufacturing quantum dot color film substrate and quantum dot color film substrate. The method is to form a quantum dot adhesive by mixing a red quantum dot material, a green quantum dot material and a photoinitiator in a thermosetting adhesive. The photoinitiator itself does not destroy fluorescence properties of quantum dot, but the photoinitiator is cleaved and can quenching the fluorescence of quantum dot after UV irradiation. A selective quenching quantum dot layer is obtained after coating a quantum dot adhesive uniformly on a color filter layer, and the light mask is used to irradiate the quantum dot adhesive on the blue sub-pixel region. Free radicals are generated by cleaving photoinitiator and are quenching the quantum dot material directly; the method is capable of meeting requirement of high gamut, simple preparation process and low cost.
