Display apparatus and method of controlling the same

A display apparatus comprising:

• a liquid crystal panel;
• a backlight unit comprising a plurality of light sources provided on an upper surface of a substrate and configured to emit light to the liquid crystal panel;
• and
• at least one processor configured to:
• identify a plurality of dimming blocks, each of which comprises at least one light source among the plurality of light sources;
• predict a temperature for each of the plurality of dimming blocks based on a dimming signal corresponding to an input image and current-specific temperature profile information corresponding to the plurality of dimming blocks;
• update the dimming signal based on the temperature predicted for each of the plurality of dimming blocks;
• and
• control a supply current for each of the plurality of dimming blocks based on the dimming signal,
• wherein the at least one processor is further configured to predict the temperature of each of the plurality of dimming blocks based on an output of a neural network that uses the dimming signal corresponding to the input image and the current-specific temperature profile information of the plurality of dimming blocks as input data.

A method of controlling a display apparatus including a liquid crystal panel, and a backlight unit including a plurality of light sources configured to emit light to the liquid crystal panel, the method comprising:

• identifying a plurality of dimming blocks, each of which comprises at least one light source among the plurality of light sources;
• generating a dimming signal according to luminance values obtained from an input image;
• predicting a temperature for each of the plurality of dimming blocks based on the dimming signal and current-specific temperature profile information corresponding to the plurality of dimming blocks;
• updating the dimming signal based on the temperature predicted for each of the plurality of dimming blocks;
• and
• controlling a supply current for each of the plurality of dimming blocks based on the dimming signal.
