Problems solved by technology

[0003] When assembling flat-panel TVs, machine manufacturers need to purchase power supplies and inverters from power supply manufacturers and inverter manufacturers to match the main circuit boards designed by themselves. The main circuit boards of TVs must be designed to retain some redundancy in order to obtain a large number of sales. Therefore, a certain space will be reserved in the selection of materials and design of the above-mentioned devices. The waste of performance, from a commercial point of view, will increase the purchase cost of power supplies and inverters

Embodiment

[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...

Abstract

The invention provides a core of a panel television, wherein a PCB is a single-layer PCB; and a main processing chip, a high frequency head, an intermediate frequency unit, an earphone terminal, a VGA terminal, an S terminal, an HDMI terminal, a power supply and an inverter are all distributed and arranged on the PCB. The core of a panel television integrates the power supply, the inverter, a master control chip and other components on the PCB with a single face; in addition, the redundancy of the power supply and the inverter are taken out of consideration during designing the core of a panel television. Compared with the prior panel television consisting of three components, the panel television adopting the technical scheme can greatly reduce the production costs.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to an improvement of a flat-panel television circuit, and more specifically relates to a flat-panel television movement which simplifies the circuit board structure of a television movement and is suitable for small-sized liquid crystal televisions. Background technique [0002] Existing flat-panel TV movement is generally made up of three parts, namely power supply, inverter and main circuit board, and wherein power supply connects main circuit board and inverter to supply them with power, and inverter drives backlight (cold cathode fluorescent lamp ), the main circuit board is equipped with a main processing chip, an audio processing chip, a video signal conversion chip, a tuner, an audio interface, and a video interface. At present, the main circuit board generally adopts a double-layer PCB or a multi-layer PCB to reduce the PCB overall area. [0003] When assembling flat-pa...
