Abstract
An LED chip for use in an LED chip array forming a continuous array of LEDs. The LED chip comprises an array of LEDs on a substrate. LEDs in a row of the array are longitudinally offset from corresponding LEDs in another row. Adjacent LEDs in each row of the array are separated by a longitudinal pitch. At least part of an end face of the substrate is angled with respect to a transverse axis of the LED chip such that the LED chip is positionable adjacent another LED chip to maintain the longitudinal pitch between adjacent LEDs on different chips.

An LED chip for use in an array of LED chips forming a continuous array of LEDs, the LED chip comprising:
- an array of LEDs arranged in a quasi one-dimensional (1-D) array on a substrate, wherein the LEDs comprise at least one μLED,
- wherein LEDs in a row of the array are longitudinally offset from corresponding LEDs in another row, and adjacent LEDs in each row of the array are separated by a longitudinal pitch,
- and wherein at least part of an end face of the substrate is angled with respect to a transverse axis of the LED chip, such that the LED chip is positionable adjacent another LED chip to maintain the longitudinal pitch between adjacent LEDs on different chips.
A method of manufacturing an LED chip comprising:
- fabricating a plurality of LEDs on a wafer substrate, the LEDs being arranged in a quasi one-dimensional (1-D) array, wherein the LEDs comprise at least one μLED, and wherein LEDs in a row of the array are longitudinally offset from corresponding LEDs in another row, and adjacent LEDs in each row of the array are separated by a longitudinal pitch;
- and
- dicing the wafer substrate such that at least part of an end face of the substrate is angled with respect to a transverse axis of the LED chip such that the LED chip is positionable adjacent another LED chip to maintain the longitudinal pitch between adjacent LEDs on different chips.
