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.

摘要： A display apparatus includes a display panel including nxm array of pixels and which sequentially drives the pixels from pixels in a first row to pixels in an n-th row, a panel driving circuit which sequentially applies first, second, third or fourth image data to the display panel, a backlight unit including a first light source disposed adjacent to the pixels in the first row and a second light source disposed adjacent to the pixels in the n-th row, and a backlight control circuit which divides each of first and second time periods into first, second, third and fourth blinking time periods, and applies a control signal to the backlight unit, where the first time period corresponds to two frames during which the first and second image data are applied, and the second time period corresponds to two frames during which the third and fourth image data are applied.
