Abstract
An integrated electro-optical package (50) including an optically transparent substrate (10) with an array (15) of light emitting devices (LEDs) (12) 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 molded base (30), having embedded electrical conductors (31) for cooperating with the LEDs (12) of the LED display chip (14) and further having a refractive or diffractive lens (60) formed within a central opening (35), 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. A driver substrate (55) having electrical connections for interfacing with the molded base (30). A plurality of driver circuits (57) connected to the molded base (30) and LEDs (12) through electrodes on the driver substrate (55).
