| description | The utility model relates to the technical field of line controller circuits, in particular to a voltage regulating and stabilizing circuit applied to a touch color screen line controller, which comprises a backlight plate, a display screen, a touch screen, a main control unit, a charging and discharging circuit, an inductance energy storage circuit and a sampling circuit. The inductance energy storage circuit is connected with power supply voltage to provide power for the backlight plate, the sampling circuit collects the voltage of the backlight plate and supplies collected signals to the main control unit, and the main control unit outputs pulse width frequency modulation according to the collected signals to control the charging and discharging circuit to charge and discharge the inductance energy storage circuit. According to the utility model, through mutual cooperation of the charging and discharging circuit, the inductance energy storage circuit and the sampling circuit, stable brightness of the backl |
