    摘要: A liquid crystal display achieving brightness uniformity, thereby reducing manufacturing costs, includes a liquid crystal panel having a first region and a second region that exhibit different brightnesses when a predetermined data voltage is applied, a memory storing a reference brightness that is to be exhibited by the liquid crystal panel when the predetermined data voltage is applied, and a brightness correction unit receiving image data corresponding to the predetermined data voltage and correcting the image data so that the first region and the second region exhibit the reference brightness.

    摘要: A backlight driving apparatus and a driving method thereof, in which the backlight driving apparatus includes a driving unit and a controller. The driving unit boosts an input voltage in response to a duty ratio of a control signal and provides the boosted input voltage to an LED array. The controller increases the duty ratio of the control signal in a step-by-step fashion by comparing a preset target value with a sequentially increasing step-setting value if a driving start signal is enabled.
