[0022] figure 1 Shown is the circuit layout diagram of a kind of flat-panel TV core of the present invention, and inverter 2, power supply 3, main control chip 4, tuner 5, intermediate frequency unit 6 and audio jack7. Wherein said PCB board 1 is a single-layer PCB board, adopting a single-layer PCB board is a most important feature of the present invention, relative to double-layer and multi-layer PCB boards, single-layer PCB boards have a larger price advantage. Inverter 2 adopts the KA7500 half-bridge connection method. The inverter 2 occupies the left side of the PCB board 1. The purpose of setting the inverter here is to remove the PCB board occupied by the inverter 2 at an appropriate time. It is separated from the PCB board 1, so there is also a cut groove 11 on the PCB board 1, which completely separates the inverter 1 and its peripheral circuits and components from other circuits on the PCB board 1. The two sides of 11 are provided with inverter socket 12 and invert...
