The LED display control system
Lossew.o.w find p-n marry emission of light form accidentally among the sic semiconductor in 1923, but the Light Emitting Diode just can not be developed rapidly until later stage of 1960. which given out by utilizing the principle of p-n
of the semiconductor to form the electricity.
In recent years, because the making of the semiconductor and preparation method are ripe and complete progressively, LED (light emitting diode) Have already occupied an leading position in the solid reveals day by day.
Led is paid attention to extensively but developed rapidly, can't separate from its advantage had by itself. These advantages are summarized:high brightness,low working voltage,little consumption,miniature and apt with the integrated circuit is matched, urged simply, long lifespan,shock-resistantly, performance is steady.Development prospect of led is broad, towards higher brightness,higher to able to bear climate, higher luminescence homogeneity, high dependability, getting panchromatic direction develop at present.
