A method of forming an active matrix, light emitting diode (LED) array, the method comprising:
- removing, from a base substrate, a layer of inorganic LED material originally grown thereupon;
- and
- bonding the removed layer of inorganic LED material to an active matrix, thin film transistor (TFT) backplane array.
A method of forming a display device, the method comprising:
- growing one or more layers of inorganic light emitting diode (LED) material on a base substrate;
- separating the one or more layers of the inorganic LED material from the base substrate by a stress-induced spalling technique;
- and
- bonding the separated one or more layers of inorganic LED material to an active matrix, thin film transistor (TFT) backplane array, thereby defining an active matrix LED array.
