Display system and method of operating the same

A display system, comprising:

• a display including a display processing unit;
• and
• a remote control (RC) including an RC processing unit that is configured to be wirelessly connected to said display processing unit, and an illuminated button that is electrically connected to said RC processing unit, said illuminated button being configured to be controlled by said RC processing unit to switch between an illuminating state and a non-illuminating state,
• wherein said illuminated button is configured to output a first operating signal to said RC processing unit upon being pressed when said illuminated button is in the non-illuminating state, said RC processing unit is configured to, in response to receipt of the first operating signal, generate a first command signal that corresponds to the first operating signal and transmit the first command signal to said display processing unit, and said display processing unit is configured to, in response to receipt of the first command signal, execute a first operation that is related to operation of said display based on the first command signal,
• wherein, when said display processing unit is in a special mode, said display processing unit is configured to transmit an illumination trigger signal to said RC processing unit for operating said illuminated button, and said RC processing unit is further configured to, in response to receipt of the illumination trigger signal, control said illuminated button to switch from the non-illuminating state to the illuminating state,
• wherein said illuminated button is further configured to output a second operating signal to said RC processing unit upon being pressed when said illuminated button is in the illuminating state, said RC processing unit is further configured to, in response to receipt of the second operating signal, generate a second command signal that corresponds to the second operating signal and transmit the second command signal to said display processing unit, and said display processing unit is further configured to, in response to receipt of the second command signal, execute a second operation that is different from the first operation based on the second command signal.
