    摘要： A scan display system includes a picture receiving unit, a scan needle, a picture display screen having first and second opposing surfaces, and a driving unit. The scan needle includes a substrate, a first color light emitting pixel array comprising a plurality of first color light emitting pixels, a second color light emitting pixel array comprising a plurality of second color light emitting pixels, and a third color light emitting pixel array comprising a plurality of third color light emitting pixels. The first color light emitting pixel array is parallel to the second color light emitting pixel array, and the second color light emitting pixel array is parallel to the third color light emitting pixel array. The first color light emitting pixel array, the second color light emitting pixel array, and the third color light emitting pixel array extend in the horizontal direction.

    摘要： A micro multi-color LED device includes two or more LED structures for emitting a range of colors. The two or more LED structures are vertically stacked to combine light from the two more LED structures vertically, and/or horizontally and reflected upward via some reflective structures. In some embodiments, each LED structure is connected to a pixel driver and/or a common electrode. The LED structures are bonded together through bonding layers. In some embodiments, planarization layers enclose each of the LED structures or the micro multi-color LED device. In some embodiments, one or more of reflective layers, refractive layers, micro-lenses, spacers, and reflective cup structures are implemented in the device to improve the LED emission efficiency. A display panel comprising an array of the micro tri-color LED devices has a high resolution and a high illumination brightness.

    摘要： A scan display system includes a picture receiving unit, a scan needle, a picture display screen having first and second opposing surfaces, a projecting unit, and a driving unit. The picture receiving unit is configured to receive picture data and transmit the picture data to the scan needle. The scan needle is configured to emit light representative of the picture data. The projecting unit is configured to project the light emitted from the scan needle to the first surface of the picture display screen. The driving unit is configured to perform a picture scanning process to form a plurality of image lines. The picture display screen is configured to receive the projected light on the first surface and display an image comprising the image lines on the second surface.
