Backlight unit, driving method thereof and associated liquid crystal display apparatus

摘要

Disclosed are a display apparatus (100) and a method of driving the same. An image signal receiver (101) sequentially outputs frames for image display. An image is displayed on a display unit (108) based on the frames and a local illumination calculation unit calculates light emission amount of a light source provided for each section of a backlight unit. A frame interpolator (102) generates sub-frames based on the frames and outputs the sub-frames to a pixel adjuster (106) which adjusts light transmittance of each pixel according to the brightness of each pixel and the amount of the light emitted from each section which is calculated by the local illumination calculation unit. Local illumination of a section is realized without increasing the number of memory devices while a frame frequency is increased.
