  • Patent number: 9946335
    Abstract: A display apparatus includes a transparent electronic display such as a non-backlit LCD screen, a display area disposed behind the transparent electronic display, and a light source for illuminating the display area. When the light source is activated, the pixels of the LCD screen, and objects behind the screen, become visible. Various examples of the display apparatus include additional enhancements to the visual image and/or functionality. These enhancements include additional monitors for coordinated displays, user-controlled turntables with coordinated informational displays, parallax compensation, RFID sensors for identifying objects to be displayed, and switchable liquid crystal films and/or polarized mirror coatings to further control revealing and concealing of objects behind the screen. Some examples of the display apparatus may include an animal habitat. The animal habitat may be selectively revealed or concealed.

  • 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.

  • Patent number: 9589513
    Abstract: A method of driving an electrowetting display device that includes a display element having a cavity; a first fluid and a second fluid within the cavity, the first fluid being immiscible with the second fluid; a surface facing the cavity; and a first electrode. The display device includes a control system for applying a voltage to the first electrode to provide a display state in response to a signal level of the voltage, wherein the control system is arranged to configure the signal level throughout a display period such that the second fluid adjoins at least a minimum area of the surface, the minimum area being greater than a zero area. The method includes applying at least one display signal level during the display period, the at least one display signal level configured such that the first fluid and the second fluid adjoin the surface throughout the display period.

  • Patent number: 9568650
    Abstract: A privacy securing film comprises a louver film consisting of transparent layers and opaque layers arranged alternately, wherein the opaque layer is made of light-absorbing beads having a mean diameter of 0.2 to 20 micrometers and binder bonding said beads each other and adjacent transparent layers, and being characterized in a micro-roughness formed at the interface between the transparent layer and the opaque layer due to the presence of said beads. The privacy securing film of the present invention has a simplified structure, excellent appearance with a simple manufacturing process as well as reduces the creation of a ghost image significantly, as compared with conventional ones.
