when did the first colour tv come out in australia
Television in Australia In 1972 it was announced that all stations would move to colour on 1 March 1975, using the European PAL standard mandated in 1968.[44][50][51] The slogan used to sell colour television to the Australian public was 'March first into colour'. Australia was to have one of the fastest change-overs to colour television in the world â€“ by 1978 over 64% of households in Sydney and Melbourne had colour television sets.[50]
LED display The 1977 model was monochromatic by design. The efficient Blue LED completing the color triad, did not arrive for another decade. Large displays now use high-brightness diodes to generate a wide spectrum of colors. It took three decades and organic light-emitting diodes for Sony to introduce an OLED TV, the Sony XEL-1 OLED screen which was marketed in 2009. Later, at CES 2012, Sony presented Crystal LED, a TV with a true LED-display (in which LEDs are used to produce actual images rather than acting as backlighting for other types of display, as in LED-backlit LCDs which are commonly marketed as LED TVs).
