An display apparatus may include a liquid crystal; a color filter overlapping the liquid crystal; a backlight unit to supply light to the liquid crystal and including a first light source emitting light of a first wavelength and a second light source emitting a second wavelength different from the first wavelength; a first power supply part to supply a first current to the first light source; a second power supply part to supply a second current to the second light source; and a processor which may control the first power supply part and the second power supply part so that the first and second currents are simultaneously supplied to the first light source and the second light source. The processor may control the first power supply part and the second power supply part so that intensity of the first current supplied to the first light source is different from intensity of the second current supplied to the second light source.

Display apparatus including light sources having different wavelengths

An electronic apparatus includes a communication interface; a memory storing a control code information of a content providing apparatus; and at least one processor configured to: based on repeatedly receiving, from a remote controller, a control signal for changing a volume value of the electronic apparatus more than a threshold number of times through the communication interface, obtain state information of the content providing apparatus, identify a current volume value of the content providing apparatus or a state of the content providing apparatus, based on the state information, and based on the current volume value of the content providing apparatus being less than or equal to a threshold value or the content providing apparatus being in a mute state, control the communication interface to transmit a control signal to change the volume value of the content providing apparatus to the remote controller based on the stored control code information.
