Therefore, more power-supplying channels are enabled for the heavy-load picture to transmit electrical signals, and fewer power-supplying channels are enabled for the light-load picture to transmit electrical signals. In the case of the light-load picture, only one power-supplying channel is enabled, which can greatly reduce the heat energy generated by the transmission of electrical signals, thereby not only reducing the temperature of the peripheral components of the power supply but also improving the operating efficiency of the circuit under the light-load picture situation.
Compared with the comparison example without a load signal generated by a timing controller to enable at least one of the plurality of power-supplying channels, the display power-supplying module of the embodiments of the present disclosure generates the load signal by the timing controller to enable at least one of the plurality of power-supplying channels for transmitting electrical signals to generate the analog positive power source. The analog positive power source is generated by a different number of electrical signals for the heavy-load picture or the light-load picture. In the case of the light-load picture, only one power-supplying channel is enabled, which can greatly reduce the thermal energy generated by the electric signal transmission, thereby not only reducing the temperature of the peripheral devices of the electric supply but also improving the operating efficiency of the circuit under the condition of the light-load picture.
In addition, a second aspect of the present disclosure provides a display device, such as a liquid crystal display device. The display device includes the display power-supplying module as described above.
According to the display power-supplying module and the display device of the above-mentioned embodiment of the present disclosure, the load signal is generated by the timing controller according to the picture signal; the power supply device enables at least one of the plurality of power-supplying channels for transmitting electrical signals according to the load signal; and the integration circuit generates the analog positive power source according to the electrical signals transmitted by the at least one power-supplying channel that is enabled. Therefore, more power-supplying channels are enabled on a heavy-load picture to transmit electrical signals, and less power-supplying channels are enabled on a light-load picture to transmit electrical signals. In the case of the light-load picture, only one power-supplying channel is enabled, which can greatly reduce the thermal energy generated by the transmission of electrical signals, thereby not only reducing the temperature of peripheral devices of the power supply but also improving the operating efficiency of a circuit in a case of the light-load picture.
