    • Substrates, assemblies, and techniques for enabling a nanowire LED pixel are disclosed herein. For example, some embodiments include growing a buffer layer on a support substrate, growing an N-type GaN layer on the buffer layer, growing a core of N-type GaN rods from the N-type GaN layer, growing an active emitting region (AER) around a portion of the N-type GaN core nanorods to create a blue AER LED, growing a AER around a portion of the N-type GaN core nanorods to create a green AER LED, and growing a AER around a portion of the N-type GaN core nanorods to create a red AER LED. This allows for the fabrication of RGB pixels on wafers monolithically (i.e., on a single wafer). The RGB pixels may then be transferred all at once, from source wafers to TFT backplanes.
    • 本文公开了用于启用纳米线LED像素的基板,组件和技术。 例如,一些实施例包括在支撑衬底上生长缓冲层,在缓冲层上生长N型GaN层,从N型GaN层生长N型GaN棒的核心,生长有源发射区域( AER)围绕N型GaN核心纳米棒的一部分形成蓝色AER LED,在N型GaN核心纳米棒的一部分周围生长AER以形成绿色AER LED,并且围绕一部分N型GaN核心纳米棒生长AER N型GaN核心纳米棒创建一个红色的AER LED。 这允许单片地(即,在单个晶片上)在晶片上制造RGB像素。 RGB像素可以一次全部传输,从源晶圆到TFT背板。
