Display apparatus and method of driving the same

A method driving a display apparatus provided with a backlight unit having a plurality of sections each of which generates a light and a display unit having pixels that allow the light to pass therethrough, the method comprising:

• receiving an image signal having consequentially a plurality of frames to sequentially output the frames;
• generating at least one (n+1)-th (n is an integer larger than 1) sub-frame to put the sub-frame between an (n+1)-th frame and an (n+2)-th frame;
• calculating a target light amount of a plurality of sections generating a light based on a brightness of the (n+1)-th frame;
• sequentially outputting the (n+1)-th frame and the (n+1)-th sub-frames while generating the light having the target light amount from the sections. and
• adjusting a light transmittance of pixels of the display unit according to a pixel brightness of the (n+1)-th frame and the (n+1)-th sub-frame, and the target light amount from the sections.

A display apparatus, comprising:

• a backlight unit having a plurality of sections each generating a light;
• a display unit having a plurality of pixels allowing the light to pass therethrough;
• an image signal receiver receiving an image signal having a plurality of consecutive frames to sequentially output the frames;
• a frame interpolator generating at least one (n+1)-th sub-frame (n is an integer larger than 1) and sequentially outputting an (n+1)-th frame and the (n+1)-th sub-frame;
• a local illumination calculation unit calculating a target light amount generated from the sections based on a brightness of the (n+1)-th frame;
• and
• a backlight controller controlling the backlight unit to generate the target amount of the light from the sections while the (n+1)-th frame and the (n+1)-th sub-frame are being displayed.
