Abstract
A monolithic Light Emitting Diode (LED) micro-display contains one or more modular LED arrays. The LED array uses quantum dot light conversion technology or Organic Light Emitting Diode (OLED). The micro-display has a spacing-saving topology and a direct current driver architecture. Its modular design is scalable, which allows manufacturing micro-displays of various sizes using the same module.
Claims4
A monolithic light-emitting diode (LED) panel, comprising:
- a first layer comprising an LED array having rows and columns of interconnected LED pixels, each LED pixel has a red LED, a green LED, and a blue LED, and each LED has a cathode and an anode;
- a second layer comprising a plurality of driver circuits, each driver circuit is connected to a power source and comprises an on-off switch;
- and
- a plurality of cathode buses and a plurality of anode buses disposed between the first layer and the second layer,
- wherein each of the plurality of driver circuits outputs a constant current to one of the plurality of cathode buses or to one of the plurality of anode buses, and
- wherein the cathode of each LED is connected to one of the plurality of cathode buses and the anode of each LED is connected to one of the plurality of anode buses.
