摘要： A pixelated light emitting diode (LED) and a method for pixelating an LED are described. The pixelated LED includes two or more monolithically integrated electroluminescent elements disposed adjacent each other on a substrate, wherein at least a portion of each electroluminescent element immediately adjacent the substrate includes an inverted truncated pyramidal shape. The method for pixelating an LED includes selectively removing material from the major surface of an LED to a depth below the emissive region, thereby forming an array of inverted truncated pyramid shapes. The efficiency of the pixelated LEDs can be improved by incorporating the truncated pyramidal shape. Additionally, the crosstalk between adjacent LED pixels can be reduced by incorporating the truncated pyramidal shape.
摘要翻译：描述像素化发光二极管（LED）和用于像素化LED的方法。像素化LED包括在衬底上彼此相邻布置的两个或更多个单片集成电致发光元件，其中紧邻衬底的每个电致发光元件的至少一部分包括倒置的截锥形形状。用于像素化LED的方法包括从LED的主表面选择性地去除材料到发光区域下方的深度，由此形成倒立的棱锥形状的阵列。像素化的LED的效率可以通过并入截锥形的形状来改善。此外，可以通过并入截头锥体形状来减少相邻LED像素之间的串扰。
