Abstract

Monolithic integrated transistors and a light emitting diode matrix epitaxially grown on a semiconductor substrate. The matrix includes a plurality of LEDs organized into rows and columns, the LEDs being formed of layers of semiconductor material epitaxially grown on the substrate. A row driver for each row includes a transistor coupled to the matrix and a column driver for each column includes a complementary transistor coupled to the matrix. The transistor and the complementary transistor are each an HBT including layers of semiconductor material positioned on the semiconductor material forming the matrix.
