The display panel and the power supply voltage adjustment means adjusting method, a display device

The present invention provides a display panel of the power supply voltage regulating device, the display panel supply voltage regulator means includes a timing controller and a power management unit, and the power management unit connected to the timing controller, the timing controller can be said to power management unit transmits a power signal voltage is reduced, the power management unit can be adjusted to reduce the output signal voltage according to the power supply voltage. Accordingly, the present invention also provides a method of a display panel supply voltage regulator and a display device. The present invention is capable of reducing the power supply voltage of the display panel, to reduce power consumption while also being able to be adjusted accordingly gamma voltage.
