Abstract: A method of driving a light source includes outputting a variable driving voltage to a light source part, sensing a first voltage based on the driving voltage and developed at a first end of the light source part, sensing a second voltage developed at a second end of the light source part due to current passing through the light source part and adjusting the driving voltage while using the first and second voltages so that power consumption by the light source part is substantially constant irrespective of temperature of the light source part and/or irrespective of a duty cycle ration being used to drive the light source part. Thus, a luminance of the light source part may be maintained at substantially uniform levels.

Abstract: A method of compensating an image to be display on a display panel is disclosed. In one aspect, the method includes receiving a first input image and adjusting a contrast sensitivity of the first input image. The method also includes calculating a first derivative of luminance of a pixel included in the adjusted image, calculating a second derivative of the luminance of the pixel, and accumulating the first and second derivatives. The method further includes determining a burn-in causing boundary based at least in part on the accumulated first and second derivatives, receiving a second input image, and comparing the burn-in causing boundary to a boundary of the second input image to determine whether to apply burn-in compensation. The method finally includes compensating a portion of the second input image corresponding to the burn-in causing boundary based at least in part on an unsharpening filter.
