  • Patent number: 9772707
    Abstract: A touch screen and fabrication method is provided. The touch screen includes a transparent substrate having a display region and a non-display region; a first polarizing film formed on the transparent substrate; and a second polarizing film formed on the first polarizing film. The first polarizing film includes a first region having a first polarization axis direction, and the first region is located in the non-display region along a vertical direction of the transparent substrate. The second polarizing film includes a second region having a second polarization axis direction, and the second region is located in the non-display region along the vertical direction of the transparent substrate. Further, the first polarization axis direction of the first region is perpendicular to second polarization axis direction of the second region.

  • Publication number: 20140175388
    Abstract: An organic light emitting diode is disclosed. The organic light emitting diode includes an anode, a hole transport layer, a light emitting layer, an electron transport layer, and a cathode. The light emitting layer includes a first phosphorescent light emitting layer, a first isolation layer, a blue fluorescent light emitting layer, a second isolation layer, and a second phosphorescent light emitting layer, which are stacked along a direction from the anode to the cathode. The first isolation layer is configured to conduct holes and to block electrons, and the second isolation layer is configured to conduct electrons and to block holes. The exciton recombination zone is constrained in the blue fluorescent light emitting layer, thus improving the light emitting efficiency and light stability of the organic light emitting diode.

    Abstract: An OLED is disclosed which includes an anode, a hole transport layer, a light emitting layer, an electron transport layer, and a cathode. The light emitting layer includes a first phosphorescent light emitting layer, a blue fluorescent light emitting layer, and a second phosphorescent light emitting layer, which are stacked along a direction from the anode to the cathode. The first phosphorescent light emitting layer includes a material capable of conducting holes and blocking electrons. The second phosphorescent light emitting layer includes a material capable of conducting electrons and blocking holes. The blue fluorescent light emitting layer includes a material capable of conducting both holes and electrons. With the phosphorescent light emitting layers having a function of restricting charges, the exciton recombination zone is constrained in the blue fluorescent light emitting layer.
