Display with charge function and display controller thereof

Abstract

A display with charge function and a display controller thereof are provided. The display provided by the present invention includes a display controller and a charge base, wherein the display controller is built-in in the display, and includes a voltage output unit and a voltage detecting/regulating unit. The voltage output unit is used to provide an output voltage according to a pulse width modulation (PWM) signal. The voltage detecting/regulating unit is used to detect the output voltage output by the voltage output unit, and generate a regulating signal accordingly to regulate the pulse width of the PWM signal. The charge base is disposed on the display for charging a storage device on the charge base according to the output voltage output by the voltage output unit, wherein the voltage value of the output voltage output by the voltage output unit is followed by the pulse width of the PWM signal.
