ABSTRACT:
An integrated electro-optical package (50) including a light emitting device (LED) display chip (14), with an array (15) of light emitting devices (LEDs) (12) formed thereon and cooperating to generate a complete image. The LEDs (12) are positioned in rows and columns and connected to connection/mounting pads (22) adjacent outer edges of the chip (14). An opaque mounting substrate (30) having a central opening (35). A driver substrate (55) having mounting pads (34), bump bonded to a plurality of pads (33) and (34) on the mounting substrate (30). A plurality of driver circuits (57) connected to the LEDs (12) through terminals on the driver substrate (55). A lens (60) mounted to the mounting substrate (30) over the array (15) of LEDs (12) and on a side opposite the LED display chip (14) to magnify, or serve as one element of an optical magnifier system, the complete image and produce an easily viewable virtual image.
