10. RGB backlight
Page 26
Graphical LCDs are only capable of
showing monochromatic pixel but
not color content. The color of the
pixel is determined by the color
of the backlight which illuminates
the display. SmartGLCD has
the
RGB color backlight
-
a very
useful feature which can give
your graphical user interfaces an
astonishing look.
Display’s backlight module consists
of three LEDs: red, green and blue,
which can shine simoutaneously.
LED can be driven by PWM signals
coming from three separate
microcontroller pins. Duty ratio of
the PWM signal determines the
intensity of color (or brightness) of
each LED. Combined together they
can create more than 16 milion
different backlight colors.
