IMAGE DISPLAYING METHOD AND DISPLAY DEVICE DRIVING THEREOF

摘要

An image displaying method comprises a step of measuring complexity and a step of controlling an amount of light of a backlight unit. Complexity of image data is measured on the basis of entropy or a most significant bit, wherein the data is displayed on a display panel including a plurality of pixels arranged in an m x n matrix form (m and n are natural numbers) and includes a plurality of unit data corresponding to the pixels The step of controlling an amount of light of the backlight unit controls the amount of light of the backlight unit with respect to the complexity. According to the image displaying method, power consumption of the display device can be reduced.
