Abstract
An integrated electro-optical package (40) including an optically transparent substrate (10) with an array (15) of light emitting devices (LEDs) (12) formed thereon, cooperating to generate a complete image, thereby forming a LED display chip (14). The LEDs (12) are positioned in rows and columns and having electrical connections adjacent outer edges of the substrate (10). A driver board (30), having embedded electrical conductors (34), plated through-hole vias (44) and/or embedded leadframes (45) for cooperating with the LEDs (12) of the LED display chip (14) and further having a plurality of driver and control circuits (42) connected to the driver board (30) and LEDs (12). A molded carrier ring (50), electrically interfaced with the driver board (30), the LED display chip (14) and the driver and control circuits (42). A molded refractive or diffractive lens (60) positioned in alignment with the array (15) of LEDs (12) of the LED display chip (14) and on a side opposite the mounting of the LED display chip (14), thereby capable of magnifying the image and producing an easily viewable virtual image.
