摘要： A liquid crystal display (LCD) and method of adjusting brightness for the LCD are provided. The LCD includes a light emitter including a plurality of luminescent bodies which are divided into a predetermined number of partial areas, a backlight driver connected to the light emitter to control the brightness of each of the partial areas of the light emitter, and a controller for calculating a representative value for adjusting the brightness of each of the partial areas of the light emitter in accordance with an input image signal and outputting the representative value as a brightness adjustment signal for adjusting the brightness of each of the partial areas to the backlight driver. Thus, the brightness of each of partial areas of a backlight can be adjusted in accordance with the input image signal to improve a contrast ratio. Also, a representative value to be used for adjusting the brightness of each of the partial areas can be lowered by a predetermined ratio to effectively reduce power needed for lighting the backlight. Also, light loss and light gain occurring between neighboring partial areas can be compensated to improve the contrast ratio, and image artifacts can be reduced.

摘要： A display apparatus and a method of adjusting brightness thereof. The display apparatus displays an image, and includes a light emitting unit divided into a predetermined number of portion areas, so that brightness is adjusted according to the respective portion areas. A driving unit is connected to the light emitting unit to adjust brightness of each of the portion areas of the light emitting unit. A control unit calculates representative values to be applied in adjusting the brightnesses of the portion areas of the light emitting unit in response to an inputted image signal, compensates the representative values with a contrast enhancement method, and outputs the compensated representative values to the driving unit. The display apparatus adjusts the representative values to be applied for adjusting the brightnesses of the portion areas of a backlight and/or gamma-corrects the inputted image to compensate for increases and decreases in brightness.
