An embodiment enables natural and smooth change in the brightness of a backlight unit and is able to reduce flicker by changing a dimming value between frames through a mixed function including a plurality of functions having different characteristics.

Dimming processing device and timing controller

In a case when a camera is disposed under a display panel, a bounded part between a camera area and a surrounding area may have a brightness difference due to a difference in pixel disposition density. The present disclosure allows minimizing such a boundary effect by compensating for greyscale values of pixels in the bounded part.

Backlight dimming processing device and timing controller for backlight dimming

An image processing device reduces power consumption of a backlight by lowering a dimming value through brightness distribution for pixels. The image data processing device includes: an image analyzing circuit configured to analyze original image data on a video image divided into a plurality of regions and calculate a representative brightness value for each region; a dimming value calculating circuit configured to calculate a dimming value for each region in order to adjust the brightness of a backlight according to the representative brightness value; a pixel analyzing circuit configured to analyze brightness distribution for a plurality of pixels in each region; a dimming control circuit configured to re-adjust the dimming value for one region according to the brightness distribution; and a dimming output circuit configured to output, to a backlight driving device, a dimming control signal for driving the backlight according to the dimming value.
