摘要:
Micro LED and microdriver chip integration schemes are described. In an embodiment a microdriver chip includes a plurality of trenches formed in a bottom surface of the microdriver chip, with each trench surrounding a conductive stud extending below a bottom surface of the microdriver chip body. Integration schemes are additionally described for providing electrical connection to conductive terminal contacts and micro LEDs bonded to a display substrate and adjacent to a microdriver chip.
