Abstract
A television includes a light source, a pulse-width-modulation (PWM) controller, and a control component. The PWM is coupled electrically to the light source, and is operable so as to generate a source control signal for controlling turning on and turning off of the light source. The control component is coupled to the PWM controller for controlling frequency of the source control signal outputted by the PWM controller. The control component has a plurality of control states that correspond to distinct display scanning frequencies of television standards, respectively. Setting of the control component in a selected one of the control states results in control of the frequency of the source control signal outputted by the PWM controller such that the frequency of the source control signal is not an integer multiple of the distinct display scanning frequency that corresponds to the selected one of the control states.
