Display apparatus and controlling method thereof

A method of controlling a display apparatus, the method comprising:

• based on information related to game type being selected, identifying an area of interest corresponding to the selected game type based on information regarding an area of interest for each game type;
• driving a plurality of light emitting diodes (LEDs) based on red, green, and blue (RGB) grayscale data of a pixel corresponding to the identified area of interest in a game image provided through a display, wherein the plurality of LEDs comprise a first LED and a second LED, each located in a different area of the display apparatus;
• identifying a first range and a second range to which a pixel value of the area of interest belongs from among a plurality of pixel value ranges based on RGB grayscale data included in the area of interest;
• driving the first LED based on a first representative light-emitting value corresponding to the first range;
• and
• driving the second LED based on a second representative light-emitting value corresponding to the second range,
• wherein the first range comprises a pixel value range to which most pixels belong, and
• wherein the second range comprises a pixel value range to which next most pixels belong.

At least one non-transitory computer readable storage medium storing one or more computer programs including instructions which, when executed by at least one processor, cause the at least one processor to:

• based on information related to a game type being selected through a user interface, identify an area of interest corresponding to the selected game type based on information stored in a memory;
• control a light-emitting state of a plurality of light emitting diodes (LEDs) based on red, green, and blue (RGB) grayscale data of a pixel corresponding to the identified area of interest in a game image provided through a display, wherein the plurality of LEDs comprise a first LED and a second LED, each located in a different area of a display apparatus;
• identify a first range and a second range to which a pixel value of the area of interest belongs from among a plurality of pixel value ranges based on RGB grayscale data included in the area of interest;
• control a light-emitting state of the first LED based on a first representative light-emitting value corresponding to the first range;
• and
• control a light-emitting state of the second LED based on a second representative value corresponding to the second range,
• wherein the first range comprises a pixel value range to which most pixels belong, and
• wherein the second range comprises a pixel value range to which next most pixels belong.
