Abstract

A display apparatus and method are provided, the display apparatus includes: a display part; a backlight unit which illuminates the display part locally; and a control part which controls the backlight unit to illuminate based on an input video signal, and changes a color information of the input video signal so that an operating state of the backlight unit is displayed on the display part.

Description

technical field [0001] A display device and a control method thereof according to the present invention relate to a backlight unit including light emitting diodes (LEDs) capable of locally adjusting brightness. Background technique [0002] Recently, a display device having a screen illuminated by a backlight unit has been widely used, such as an LCD monitor. The display device adjusts the brightness of the screen by adjusting the brightness of the backlight unit. [0003] Display devices of the related art use fluorescent lamps emitting white light, such as cold cathode fluorescent lamps (CCFL), hot cathode fluorescent lamps (HCFL), etc., for a backlight unit. [0004] However, display devices using fluorescent lamps cannot represent the entire color gamut due to the optical characteristics of light emitted by fluorescent lamps. [0005] Therefore, display devices that use LEDs for backlight units to adjust the brightness of the backlight units are widely used. If LEDs a...
