Display apparatus and control method thereof

A method of controlling a display apparatus comprising a self-luminous display panel, the control method comprising:

• receiving image data;
• and
• designating a pixel of the self-luminous display panel which corresponds to the image data and displaying an image which corresponds to the image data by discharging the self-luminous display panel so that the designated cell emits light,
• wherein the displaying of the image comprises receiving a control instruction to control an operation of an external device;
• and converting the control instruction into a waveform according to a protocol that the external device is able to receive and controlling the external device to operate by electromagnetic interference (EMI) radiated from the self-luminous display panel by additionally discharging the self-luminous display panel with the converted waveform during a period in which the self-luminous display panel is discharged.

A display apparatus comprising:

• a self-luminous display panel;
• a processor configured to designate a pixel of the self-luminous display panel which corresponds to image data and to process the image data by discharging the self-luminous display panel so that the designated pixel emits light;
• and
• a controller configured to convert a received control instruction into a converted waveform and control an external device by additionally discharging the self-luminous display panel with the converted waveform during a period of time in which the self-luminous display panel is discharged.
