LED Assembly with Transistor Drain Cathode

The patent combines the transistor's drain electrode with the LED's cathode terminal, merging two separate components into one integrated structure. This eliminates the need for a separate n-type LED electrode while maintaining both the transistor's switching function and the LED's light emission function, thereby simplifying manufacturing without compromising functionality

The drain electrode of the transistor is designed to serve dual purposes: as the control terminal for the transistor and as the cathode terminal for the LED. This multi-functional design allows a single component to fulfill multiple roles in the device, reducing the total number of components and manufacturing steps

The patent merges the formation of the transistor's drain electrode with the formation of the LED's cathode terminal into a single fabrication process step. This integration eliminates additional fabrication steps and material deposition processes, making manufacturing easier while ensuring the LED structure remains complete and functional

The transistor's drain electrode structure serves its own function as the LED's cathode terminal, eliminating the need for separate cathode terminal fabrication. The existing drain electrode structure is utilized for dual purposes, reducing manufacturing complexity without requiring additional materials or process steps
