Abstract
An electronic apparatus and a light-emitting module driving circuit thereof are provided. The electronic apparatus includes a light-emitting module and a driving circuit. The driving circuit is coupled to the light-emitting module and is configured to generate a driving signal set to drive the light-emitting module. The driving circuit includes a first driver, a second driver, and a switching circuit. The first driver receives a control signal related to an operation status of the electronic apparatus and generates a first signal set according to the control signal. The second driver includes at least one resistor which receives system power and accordingly generates a second signal set. The switching circuit is coupled to the first driver and the second driver to receive the first signal set and the second signal set, respectively. When the switching circuit does not receive the first signal set, the switching circuit takes the second signal set as the driving signal set.
