More Information
Summary:The invention discloses a digital controller. The digital controller according to the invention includes a digital processing unit which has a look-up table. Plural default voltage values and plural duty cycle parameters are stored in the look-up table. Each default voltage value corresponds to one duty cycle parameter. In response to an input signal from a power supply to the digital controller, the digital controller searches the look-up table to find out a default voltage value matching the voltage value of the input signal, and generates a control signal having a duty cycle parameter corresponding to the default voltage value to control a display module such that the electricity supplied to the display module substantially has a permanent power.
