Abstract (en)

[origin: DE19621911A1] The display has red, green and blue light emitting diodes, one or more microcontrollers, lenses and a liquid crystal display or LCD. The monochrome display (4) is back illuminated with green, blue and red light emitting diodes(1-3) and the red, blue and green light components are generated successively to produce a colour image. The LCD is operated at a higher clock frequency than the individual light sources. The background illumination can consist of LEDs operated with pulse width modulation.
