The present invention discloses a backlight control circuit, comprising: a
voltage supply circuit, which is a boost converter circuit for receiving
an input voltage from an input terminal and generating an output voltage
to an output terminal, the output voltage being provided as an operating
voltage for a plurality of light emitting devices; at least one input
capacitor electrically connected between the input terminal and ground;
and at least one output capacitor electrically connected between the
output terminal and the input terminal.
