摘要： A display apparatus includes a display panel and a backlight assembly including a lamp and an inverter. The inverter includes a main transformer, a main driver and a voltage controller. The main transformer applies a driving alternating current (AC) voltage to the lamp. The main driver generates an output signal controlling the main transformer based on a feedback signal from the main transformer. The voltage controller is electrically connected to a feedback terminal of the main driver to control a maximum level of a voltage applied to the feedback terminal.

摘要： In a method of driving a light source of a light source module including a plurality of driving blocks, an image signal is analyzed and a target luminance corresponding to each of the driving blocks is determined. A dimming level of each of the driving blocks is determined by using the target luminance. A driving signal is generated, and the driving signal has a pulse width based on the dimming level and a variable frequency in accordance with a processing mode of the image signal. The driving block is driven by using the driving signal.
