Abstract

An image display apparatus may include a panel, a backlight lamp to output light to the panel, and a drive controller to control current flowing in the backlight lamp. When a level of the current flowing in the backlight lamp during a first period is a first level; the drive controller controls the level of the current flowing in the backlight lamp during a second period (after the first period) to be a second level. A deviation of power consumption may be reduced.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 USC 119 to Korean Application No. 10-2014-0041391 filed Apr. 7, 2014, the subject matter of which is incorporated herein by reference. technical field [0003] Embodiments relate to an image display device and an operating method thereof. More particularly, the embodiments may relate to an image display device capable of reducing variation in power consumption and an operating method thereof. Background technique [0004] Digital broadcasting may refer to broadcasting that transmits digital video and audio signals. Compared with analog broadcasting, digital broadcasting can exhibit low data loss, excellent error correction, high resolution, and high definition due to its robustness against external noise. Unlike analog broadcasting, digital broadcasting can provide two-way services. [0005] The resolution of image display devices has been increased in response to requests f...
