Abstract:
1. An electronic device with typing prompt function, comprising: a plurality of labeled transparent keys arranged on a keyboard, wherein each of the transparent keys is connected to a Light Emitting Diode (LED); a storage configured for storing at least one dictionary corresponding to a character input method, and relationships between the LEDs and ASCII codes of the input of the transparent keys, wherein the dictionary comprises a plurality of words and each of the words comprises at least one ASCII code of the input of a transparent key; a shift register configured for storing the ASCII codes of the input of the transparent keys; an ASCII code determining module configured for determining which key is pressed; an ASCII code storing module configured for storing the ASCII codes of the input of the pressed transparent keys to the shift register; a searching module configured for searching in the dictionary corresponding to the character input method in use to find at least one ASCII code as a possible next input towards typing a word from the dictionary according to the stored ASCII code; and an LED controlling module configured for lighting up the at least one LED corresponding to the at least one found ASCII code according to the relationships between the LEDs and the ASCII codes of the input of the transparent keys.
