Abstract

An electro-optical device preferably includes a printed circuit board (PCB) having a cutout region or a rigid region. A leadframe having an electro-optical semiconductor device arranged thereon can be arranged in proximity to the cutout region of the PCB. Alternatively, the electro-optical device can be arranged on the rigid region of the PCB. A lens is preferably arranged over the electro-optical semiconductor device. A connector array can also be arranged on the PCB to communicate electrical signals with an external device. An interface circuit, such as a driver circuit or an amplifier circuit, can also be arranged in close proximity to the electro-optical semiconductor devices on the leadframe or the PCB.
