ABSTRACT:
An integrated electro-optical package (50) including a first light emitting device (LED) display chip (28) and at least one additional LED display chip (30), each composed of an optically transparent substrate (10) with an array (15) of LEDs (12) formed thereon and cooperating to generate a complete image. The LEDs (12) of the first LED display chip (28) are constructed to emit light of a wavelength different than the light emitted by the additional LED display chip(s) (30), thereby creating a different color menu or object bar (156) within the view (150) generated. A mounting substrate (25), having connection pads (32), bump bonded to the pads on the optically transparent substrate (10). A driver substrate (55) having connections to the pads (32) on the mounting substrate (25). A plurality of driver and control circuits (57) connected to the LED display chips (28) and (30) through electrodes on the driver substrate (55). A lens (73) in alignment with the LED display chips (28) and (30) to magnify the complete images and produce an easily viewable virtual image.
