    摘要: A method for driving a light source first sets a frame time and a unit time, and calculates the number of the unit time that the frame time can contain. Based on the turned-on duration (DTi) of a light-emitting device of the light source and the unit time, the turned-on numbers (Ni) and the compensation times (CTI) of the light-emitting devices are calculated. The light-emitting device is driven to emit a light beam according to the turned-on numbers (Ni) and the compensation times (CTI). The present driving method can be applied to light source and backing light source of liquid crystal displays.
