Embodiment Construction

[0027] A number of implementations of the present invention will be disclosed below with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the sake of simplifying the drawings, some well-known and commonly used structures and elements will be shown in a simple and schematic manner in the drawings.

[0028] Herein, when an element is referred to as "connected" or "coupled", it may mean "electrically connected" or "electrically coupled". "Connected" or "coupled" may also be used to indicate that two or more elements cooperate or interact with each other. In addition, although terms such as “first”, “second”, . Unless clearly indicated by the context, the terms do not imply any par...

Abstract

The invention discloses a voltage regulation circuit, a voltage regulation method and a display device. The voltage regulation circuit comprises an impedance circuit, a control unit and a power supply circuit. The impedance circuit has a first node and a second node. The second node is electrically connected to the load. The control unit is electrically connected to the first node and is used for controlling a first voltage value of the first node according to the control signal. The input end of the power supply circuit is electrically connected to the second node, and the output end of the power supply circuit is electrically connected to the load. The power supply circuit outputs a supply voltage to the load according to a second voltage value of the second node. Therefore, the voltage regulating circuit can provide different voltage values according to the requirements of the load.

Description

technical field [0001] The content of the present invention relates to a voltage regulation circuit, especially a circuit capable of changing the magnitude of the output control voltage. Background technique [0002] When the electronic device is in different operating states, its internal power supply circuit often needs to generate different voltages. The traditional method uses multiple sets of DC-DC modules (DC-to-DC modules) to achieve the purpose of generating multiple sets of different voltages, but this method consumes too many components and also increases the area of ​​fixed components. This further affects the cost and operational stability of the electronic device. Contents of the invention [0003] The purpose of the present invention is to provide a voltage regulating circuit, which can provide different voltage values ​​according to the requirements of the load. [0004] The content of the present invention relates to a voltage regulation circuit, includin...
