  • Patent number: 9500902
    Abstract: Disclosed herein is a display device switchable between a mirror mode and a display mode. The display device includes a display panel, a polarizing element and a reflective polarizer. The display panel has a light-emitting surface for emitting a polarized light. The polarizing element has an absorption axis, and is disposed on a side adjacent to the light-emitting surface. The polarizing element is switchable between a polarizing mode and a non-polarizing mode. When the polarizing element is operated in the polarizing mode, the polarizing element absorbs a polarized light in the polarization direction parallel with the absorption axis. When the polarizing element is operated in the non-polarizing mode, the polarizing element allows the polarized light emitted from the display panel to pass there through. The reflective polarizer is disposed between the display panel and the polarizing element.

  • Patent number: 9035286
    Abstract: A color light-emitting diode using a blue light component to produce red light and green light is disclosed. A blue-light emitting material is provided between a cathode layer and an anode layer for emitting the blue light component. A light re-emitting layer has a first material in a first diode section arranged to produce a red light component in response to the blue light component, and a second material in a second diode section arranged to produce a green light component in response to the blue light component. A transparent material in a third diode section allows part of the blue light component to transmit through. The anode layer is partitioned into three electrode portions separately located in the three diode sections, so that the red, green and blue light components in the diode sections can be separately controlled.
