<p>The invention relates to a control circuit for a hair drier with touch screen colorful display. The control circuit includes a monolithic processor control unit, a power source input unit, a key-press input unit, a zero-crossing input unit, a temperature control unit, a wind speed and anion control unit, a multimedia processing chip unit, a random storage unit, a touch control unit, a liquid crystal display unit and a backlight source unit. Input signals of the touch control unit are transmitted to the multimedia processing chip unit to be processed; the processed signals are transmitted to the monolithic processor control unit; after the functions of the signals are identified by the monolithic processor, the monolithic processor control unit outputs control signals to the multimedia processing chip for processing, simultaneously temporarily stores the output data to be displayed in the random storage unit, and finally the data is output to the liquid crystal display unit and the backlight unit. The touch control unit, the liquid crystal display unit and the backlight source unit form a display module. The invention can be applied to various types of hair driers, so that the hair drier has a humanized operation interface and multiple functions, and can meet the increasing operating requirement of people on the hair drier.</p> |
