Abstract

The invention discloses a power supply circuit of a split-type television and the split-type television. The power supply circuit of the split-type television comprises a voltage conversion module arranged in a television box of the split-type television, a main board and a power supply module used for outputting power supply voltage; the main board is used for sending a trigger signal to the voltage conversion module when a standby starting signal triggered by a user is detected; the voltage conversion module is used for switching a standby voltage provided for the mainboard into a first working voltage to supply power to the display module when the trigger signal is received; the mainboard is also used for enabling the voltage conversion module to provide a second working voltage for thedisplay module when a connection signal continuously sent by the display module is detected, and stopping supplying power to the display module when it is detected that the connection signal is disconnected,. A discharge sparking phenomenon generated when a user inserts and pulls a connecting line can be avoided, the internal structure of the circuit is protected and the service life of the circuit is prolonged.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a power supply circuit of a split TV and the split TV. Background technique [0002] In the current split TV design, a dual power supply design is usually adopted, that is, the TV box and the display screen of the split TV are powered by two independent power supplies. The split TV with dual power supply design needs both power cords to be connected to the mains to be able to use the TV. If there are not enough AC ports near the split TV, you need to use a power strip to simultaneously power the TV box. Power supply with the display screen, this dual power supply design is very cumbersome. [0003] Therefore, one of the power sources can be powered by alternating current and provide a stable voltage to the other power source, so that the split TV can run after being connected to the mains through a power cord. In this design, a connection line is needed between the TV box and the displa...
