DISPLAY DEVICE AND LED DRIVING DEVICE THEREOF

Abstract: an led driving device includes an led load, a control module and a driving module. the led load has a driving characteristic and a load energy. the control module provides a frame time and a first pulse width to calculate a total pulse number in the frame time. the control module generates a pulse intensity and a second pulse width according to the driving characteristic of the led load. the control module generates a pulse density according to the load energy of the led load. the driving module generates a driving signal to the led load according to the pulse intensity, the second pulse width and the pulse density.
