Abstract
The present invention relates to a noise maintaining and shielding structure of a plasma display panel, which comprises image input terminals which are installed on an acoustic image and vision signal board and a field rolling printed circuit board which is arranged on a supporting frame. In order to prevent the condition that noise is transferred and maintained by the image input terminals, the field rolling printed circuit board and the side of back surfaces between the image input terminals are provided with noise shielding disks with elasticity along the side direction of an assembly. The noise shielding disks are provided with concave central extension parts and extension inclined planes which use the central extension parts as the center and have a double side in the direction of each supporting frame and the acoustic image and vision signal board. The central extension parts contact the assembly, and the ends of the inclined planes contact each supporting frame and the acoustic image and vision signal board. The present invention can effectively shield maintaining noise which enters the field rolling printed circuit board and the image input terminals of the plasma display panel.
Description
Technical field
The present invention relates to a kind of on plasma display, use keep the noise isolation structure, particularly a kind of for prevent among plasma display panel assembly, to produce keep noise effect show up the rolling printed circuit board (PCB) hinder drives plasma display keep the noise isolation structure.
Background technology
The requirement that constitutes of the inside of various performances such as the capacity of display of article on plasma body display panel (Plasma Display Pnael:PDP), gray scale, contrast, afterimage, visual angle and display now is more and more higher.
Plasma display is a display device of utilizing gas discharge basically, Plasma Display
Each unit in the panel discharges and constitutes red-green-blue and form picture.Cell discharge characteristic because of this plasma display, produce more noise than other products, especially plasma display is just more outstanding, as shown in Figure 1, in order to keep the plasma discharge phenomenon, on the matrix of plasma display, emit at a certain time interval and keep pulse, and this pulse is transferred to through P on the image input terminal J of the field rolling printed circuit board (PCB) 30 that is arranged within phonotape and videotape and the vision signal plate 20 by the noise transmission road, thereby produces the noise of keeping pulse on picture.
This noise (sustain noise) of keeping influences the rolling printed circuit board (PCB) 30 of showing up, and hinders the driving of circuit, and therefore, the image quality of article on plasma body display panel has harmful effect.
In order to address this problem, as shown in Figure 2, traditional way is whole the rolling printed circuit board (PCB) 30 full-shields 30a that gets up, but this method can not cover outward the image input terminal J of outstanding field rolling printed circuit board (PCB), and also can not block the noise of coming in by input terminal.
Summary of the invention
The objective of the invention is to propose in order to solve the problem that above-mentioned conventional art exists, what can effectively shield the plasma display of keeping noise that the image input terminal in the printed circuit board (PCB) in plasma display enters exactly keeps the noise isolation structure.
In order to achieve the above object, the technical scheme of technical solution problem of the present invention is: comprise being installed in the image input terminal on phonotape and videotape and the vision signal plate and being loaded on the interior field rolling printed circuit board (PCB) of support frame, in order to prevent to keep noise by the propagation of image input terminal, rear side between above-mentioned rolling printed circuit board (PCB) and image input terminal, be provided with resilient noise isolation dish along the components side direction, this noise isolation dish is to have recessed central extension and is that the center is towards each support frame with central extension, the direction of phonotape and videotape and vision signal plate is made two-sided prolongation dip plane, above-mentioned central extension is contacted with on the assembly, the end of above-mentioned dip plane and each support frame, phonotape and videotape and vision signal plate contact.
In order to shield above-mentioned rolling printed circuit board (PCB) and noise, a shielding cover board is set also.
The end of above-mentioned dip plane is made and is hook-type.
The effect of invention:
Plasma display of the present invention can shield the noise of keeping that enters plasma display internal field rolling printed circuit board (PCB), image input terminal effectively with keeping the noise isolation structure.

Embodiment
Followingly embodiments of the invention are described in detail with reference to accompanying drawing.
Fig. 3 is the shielding construction synoptic diagram that noise is kept in shielding of the present invention.
The shielding construction of keeping noise of the present invention comprises and is loaded on the image input terminal on phonotape and videotape and the vision signal plate 20 and is loaded on field rolling printed circuit board (PCB) 30 in the support frame, in order to prevent to keep noise by image input terminal J propagation, the rear side between above-mentioned rolling printed circuit board (PCB) 30 and image input terminal is provided with the resilient noise isolation dish 10 of keeping along assembly M side direction.
This keeps noise isolation dish 10 is to have recessed central extension and is that two-sided prolongation dip plane is made towards the direction of each support frame, phonotape and videotape and vision signal plate 20 in the center with central extension.
One side of above-mentioned recessed central extension by screw retention on phonotape and videotape and vision signal plate 20, and opposite side contacts with the corresponding component of assembly, in addition, the end of above-mentioned dip plane is contacted with on each support frame and phonotape and videotape and the vision signal plate 20, therefore, the noise of keeping that assembly produces has shielded by the noise isolation dish, especially keep noise by enter into phonotape and videotape and vision signal plate 20 by the dip plane by what the image input terminal of field rolling printed circuit board (PCB) was imported, so, can block and keep entering of noise.
Press embodiments of the invention,, a shielding cover board 30b is set also in order to shield above-mentioned rolling printed circuit board (PCB) 30 and noise.Blocked the noise of keeping of an influence rolling printed circuit board (PCB) itself by this shielding cover board.
The end of above-mentioned two dip plane of keeping noise isolation dish 10 is made and is hook-type, and the corresponding component of this crotch part and the support frame of phonotape and videotape and a vision signal plate 20 and a rolling printed circuit board (PCB) 30 has hooked, so, might combining closely with elastic force.
Fig. 4 a and Fig. 4 b be the shielding of the present invention shielding construction of keeping noise phase analysis figure is set.
At first, load onto noise isolation plate 10, assemble phonotape and videotape and vision signal plate 20 at last, just can prevent that the noise of the image input terminal by field rolling printed circuit board (PCB) from entering at the connecting portion of the field of assembly M rolling printed circuit board (PCB) 30.
