Abstract
A growth substrate including micro-light emitting diode (LED) chips and a method of manufacturing a light emitting diode display using the growth substrate are disclosed. The growth substrate includes LED chips. The LED chips are divided into n groups each including p LED chips, where each of the n and p is an integer equal to or greater than 2. At least two of the n groups are adjacent to each other. Each of the n includes a first LED chip having a directionality toward a first direction and a second LED chip having a directionality toward a second direction different from the first direction.
Claims19
A growth substrate, comprising:
- light emitting diode (LED) chips,
- wherein the LED chips are divided into n groups each including p LED chips, where each of the n and p is an integer equal to or greater than 2,
- wherein at least two of the n groups are adjacent to each other,
- wherein each of the n groups comprises a first LED chip having a directionality toward a first direction and a second LED chip having a directionality toward a second direction different from the first direction.
A method of manufacturing a light emitting diode display, comprising:
- providing a growth substrate on which light emitting diode (LED) chips are grown, the LED chips being at least divided into first to fourth groups;
- and
- providing a transfer substrate on which pixels having a preset pitch are arranged,
- wherein the first to fourth groups are arranged in a matrix,
- wherein each of the first to fourth groups comprises a first LED chip having a directionality toward a first direction and a second LED chip having a directionality toward a second direction different from the first direction.
