摘要:
A direct view multicolor light emitting device includes blue, green and red light emitting diodes (LEDs) in each pixel. The different light emitting diodes can be formed by depositing different types of active region layers in a stack such that deposition area of each subsequent active region is less than the deposition area of any preceding active region, and by patterning the active region layers into different types of stacks. The active region layers may be formed as planar layers, or may be formed on semiconductor nanowires. The active region layers can emit light at the respective target wavelength range. Alternatively, at least one of green and red phosphor materials, dye materials, or quantum dots may be used instead of or in addition to the active regions that emit light at a wavelength different from a target wavelength of a respective LED.
摘要(中):
直视多色发光装置包括每个像素中的蓝色,绿色和红色发光二极管(LED)。 可以通过在堆叠中沉积不同类型的有源区域层来形成不同的发光二极管,使得每个后续有源区域的沉积面积小于任何前面的有源区域的沉积面积,并且通过将有源区域层图案化成不同类型 的堆栈。 有源区层可以形成为平面层,或者可以形成在半导体纳米线上。 有源区域层可以在相应的目标波长范围发射光。 或者,可以使用绿色和红色磷光体材料,染料材料或量子点中的至少一种来代替或者除了以与相应LED的目标波长不同的波长发光的有源区域之外。
