Embodiment Construction

[0026] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure and features provided by the present invention are described in detail as follows:

[0027] Such as Figure 2-Figure 5 As shown, a method for realizing the integration of display printed circuit boards, the specific implementation steps are as follows:

[0028] (1) Signal module settings

[0029] Signal board circuit design, designed for double-layer PCB (printed circuit board). The power supply part is provided from the IP board by a uniform voltage (5V or 12V), and the voltages required for designing the Scaler chip are 3.3V, 1.8V, 2.5V, etc. The interface part uses the interface method of SMD type (chip form). When designing the PCB, the size and layout design is compact, and all devices are arranged on one side, such as side A; wiring, vias and pads are set on the other side, such as side B.

[0030] There is a rectangular pad on the edge of the ...

Abstract

The invention relates to a method for realizing the integration of the printed circuit boards of a monitor. The method comprises the following steps: the signal board circuit is designed to contain a two-layer printed circuit board; the interface part adopts the interface mode of surface mount type; one side of the printed circuit board is provided with all the elements, the other side is provided with a track, via holes and pads; the edge of the back of the printed circuit board is provided with a rectangular pad while the corresponding position on the front is provided with the same rectangular pad; the edge is provided with a metallized via hole for connection; and the pad is connected with actual signals through the wires on the back. The power supply plate is designed to contain a single-layer printed circuit board; when the printed circuit board is drawn, a rectangular space is reserved for welding the signal board; the back of the printed circuit board is provided with a pad corresponding to the space of the signal board; and a isolation belt for preventing interferences is arranged between the power source part and the signal part. By using the method of the invention, the circuit design of the monitor can be simplified, the integration of the power supply plate and the signal plate can be realized, the working procedure of manual assembly can be avoided, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a design method of a display circuit, in particular to a method for realizing the integration of display printed circuit boards. Background technique [0002] At present, the internal circuit of a display product is generally divided into two parts: a power board (IP Board) and a signal board (Signal Board). The function of the power board is to convert the public AC power supply (220V) into the DC voltage source (12V, 5V, etc.) required by the system through a transformer and rectifier device; the main circuit includes rectifiers, transformers, oscillators, voltage stabilizers, etc. The signal board is responsible for processing image signal information, including CPU, memory, control signals and signal connection parts. The signals on the power board are mostly high-voltage and low-frequency signals, and the signals on the signal board are mostly low-voltage and high-frequency signals. In order to avoid mutual interference, ...
