True color flat panel display using LED dot matrix and LED dot matrix drive method and apparatus

摘要

The invention relates to a pixel for use in an electronic display in which the individual elements are light emitting diodes. The pixel (21) includes an LED (44) that emits in the red portion of the visible spectrum, an LED (45) that emits in the green portion of the visible spectrum, and an LED (46) that emits in the blue region of the visible spectrum. The red, green and blue LEDs (44, 45 and 46) are adjacent one another and have their respective top anode contacts located in a substantially common plane on the pixel. The red LED (44) includes at least one active layer of aluminium gallium arsenide (A1GaAs). The bottom contacts of all of the LED's can likewise be placed in a common plane, which is preferably different from the common plane of the top contacts.
