Lot of users feels the inconvenience of using remote controller in low/no light conditions. Some people may have to turn on a light in a room when other people may be sleeping. Presently phosphor illumination (glow in the dark) is being used. This needs light to charge, so if it is in long term darkness it would be ineffective. The glow in the dark illumination lasts for only a few minutes. Some remote controllers only illuminate buttons once a function key is pressed. The possibility of pressing an unwanted function key to activate the illumination is very high. The user will still have to search for that key in darkness.
This invention would ease the visibility of buttons in low/no light conditions. It eliminates the possibility of performing an unwanted function. It also eliminates the possibility of disturbing other people, for example, having to turn on a light in a room when other people may be sleeping.
