Abstract

The invention relates to a filter coating provided with a black frame on the periphery and applied to a PDP (plasma display panel) module. The filter coating comprises a PET (polyethylene terephthalate) film and a protective film which is adhered on and covers the front surface of the PET film, wherein an HC (hydrocarbon compound) layer is arranged between the PET film and the protective film, a COLORPSA layer with a light filtering function is adhered on and covers the other surface of the PET film, a film closely adhering the COLORPSA layer is a release film of the filter coating, and black filler is additionally filled between the PET film and the release film. According to the filter coating disclosed by the invention, a face frame is not required for a plasma display screen, so that a panel is free of a frame, and a light and thin design of the plasma display screen is realized; and meanwhile, an effect that the panel is provided with the black frame can be realized by utilizing a black layer, and the appearance beautification of the plasma display screen is realized.

Description

A kind of filter coating for having black surround around the PDP module

Technical field

The present invention relates to the filter coating field, particularly relate to a kind of filter coating for having black surround around the PDP module.

Background technology

Traditional plasm TV mainly shows that by plasma module, bonnet, face frame, filter coating consist of.Plasma shows that module generally is connected to bonnet by the mode of screw, filter coating sticks on plasma and shows on the module, because the existence of face frame causes complete machine the place ahead to have eye socket, this pursues frivolous today day by day at consumer electronics, can not satisfy the product user demand.Phenomenon is exposed because whole equal printing opacity of traditional filter coating, the anchor point that produces in the PDP display production run and black surround show money or valuables one carries unintentionally will be exposed outside outside, affect on the whole the face shaping of PDP display.

Summary of the invention

For overcoming the problems referred to above, by in traditional filter coating, increasing black layer, realize that PDP display has black surround without around the frame, makes PDP display frivolous, good looking appearance.

The present invention adopts following technical scheme: a kind of filter coating for having black surround around the PDP module, comprise PET film and the diaphragm that is covered on the PET film front, between is provided with the HC layer, another side at the PET film is covered with the COLOR psa layer that one deck has filtering functions, and that is close to the COLOR psa layer is the release film of filter coating; Increase the black filler at PET film and release film, form black layer.

In technique scheme, described black layer is divided into and is printing opacity printing ink and light tight printing ink two schemes, and the light penetration of described printing opacity printing ink is in the 3%-15% scope.

In technique scheme, described filter coating pastes on the PDP display surface.

In technique scheme, the black layer of described filter coating is presented on outside the viewing area of PDP display, forms the black housing.

In technique scheme, in the black housing of light tight printing ink, the optical registration hole is arranged, the diameter in described optical registration hole is 2-5mm.

In technique scheme, use light penetration to be the printing opacity printing ink in the 10%-20% scope in the optical registration hole.

The invention has the advantages that: the filter coating of the application of the invention, can make plasma panel not need to use the face frame, and can reach panel without frame, realize the lightening design of PDP display, adopt simultaneously black layer can realize that panel has the black surround effect, realize that the outward appearance of PDP display is beautified.

Description of drawings

The present invention will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the schematic cross-section of traditional filter coating;

Fig. 2 is practical application synoptic diagram of the present invention;

Wherein: the 1st, diaphragm 2 is that HC layer 3 is that PET film 4COLOR psa layer 5 is release films

The 6th, PDP display edge 7 is that black surround 8 is that optical registration hole 9 is PDP display viewing areas.

Embodiment

The present invention is described further below in conjunction with accompanying drawing.

The present invention is a kind of filter coating that has black surround around the PDP module, its objective is by pasting one deck filter coating at plasma panel, and the edge of filter coating is done add the black treatment of packing, and PDP display is realized without frame, attractive in appearance, frivolous.

In traditional plasma panel, the transmittance of the filter coating that adopts all is the same, plasma panel is in the production installation process, a lot of mark points can appear, and optics generally all adopt installation display face frame in order to block these holes, but the volume of face frame is all generouser to being the hole, eye socket can occur after the installation, and display is just frivolous not.

As shown in Figure 1, traditional filter coating comprises release film 5 that PET film 3 and display screen paste, is clipped in COLOR psa layer 4 between PET film 3 and the release film 5, the diaphragm 1 of the superiors, is clipped in the HC layer between diaphragm 1 and the PET film 3.Phenomenon is exposed because whole equal printing opacity of traditional filter coating, the anchor point that produces in the PDP display production run and black surround show money or valuables one carries unintentionally will be exposed outside outside, and the outward appearance vision is very poor.

Use of the present invention is because removed display face frame, so irregular zone has just appearred in the position at the original installed surface frame of display screen, in order to cover up these irregular zones, just in traditional filter coating of application site, increase the black filler, namely between PET film 3 and release film 5, increase the black filler, make traditional filter coating be thought of as the filter coating that has black surround all around.

As shown in Figure 2, this is that filter coating pastes the front schematic view on display screen, and wherein black surround 7 has several optical registration holes 8 in black surround between 6 plasma panel viewing areas 9, PDP display edge, and the diameter in optical registration hole 8 is 2-5mm.

In above-mentioned example, black filler between PET film 3 and the release film 5 is black ink, black ink divides printing opacity and light tight dual mode, and the transmittance of the black ink of printing opacity is 3%-15%, and the transmittance of the filter coating in ion display screen viewing area 9 is 53%.It is lower time of the lighttight situation of black ink at the black filler, because aborning, mark point palpus optical imagery needs printing opacity, needs the position of printing opacity, and be optical registration hole 8, not brushing the black ink that transmittance is 3%-15% on the optical registration hole, is the printing opacity printing ink of 10%-20% but adopt transmittance, and so visually also is black, can not affect outward appearance, block again the mark point.When the black filler was the black ink of printing opacity, its transmittance was between the 3%-15%, selected according to equipment, can be without the optical registration hole.

The PDP display that generates finished product has been removed eye socket, and the mirror-smooth of plasma panel presents light, thin outward appearance, the good visual effect of black side frame.

Disclosed all features in this instructions except mutually exclusive feature, all can make up by any way.

Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
