  • Patent number: 11353644
    Abstract: A blended display device is provided. The display device includes a display panel having a first substrate located at a back side and a second substrate located at a display side, and a directional nanowire grid polarizer (NWGP) layer disposed on the second substrate. The display panel is switchable between first and second operational modes. The directional NWGP layer has a NWGP direction. The directional NWGP layer includes at least one colored coating disposed on at least one pattern region. In the first operational mode, the directional NWGP layer functions as a polarizer for the display panel, and the display panel is used to display an image. In the second operational mode, the display panel does not display an image, and an ambient light incident toward the display panel is at least partially reflected by the pattern region of the directional NWGP layer to show a predesigned color pattern.

    Abstract: A light emitting diode (LED) display panel includes a LED array, a color change layer, and a shutter layer disposed therebetween. The LED array is formed by multiple LEDs, defining multiple pixels. Each pixel has a corresponding LED and multiple sub-pixels. The color change layer includes multiple color change structures corresponding to the sub-pixels. The shutter layer defines multiple shutter structures correspondingly aligned to the sub-pixels and the color change structures. Each shutter structure is independently controlled to be switchable between a first state, where light emitted by the corresponding LED is prevented from reaching the corresponding color change structure, and a second state, where light emitted by the corresponding LED is allowed to reach the corresponding color change structure. For each pixel, only the shutter structure corresponding to one sub-pixel is in the second state, and the shutter structures corresponding to the other sub-pixels are in the first state.
