Abstract
The present invention relates to a plasma display panel filter. It includes antireflection coating, near infrared screened film, transparent substrate and electromagnetic interference shielding film. The described transparent substrate includes at least two transparent plastic resin layers and at least a adhesive film sandwich between plastic resin layers.
Description
Technical field
The present invention relates to PDP (plasma display panel), more specifically, relate to the light filter and the manufacture method thereof of plasma display panel.
Background technology
In the prior art, in the exploitation of digital multimedia display device, plasma display panel (PDP) is compared with other display device to have advantage and be subjected to more concern on market.The display device of the radioactivity when PDP is R, G, a B fluorescent material in the ultraviolet ray excited discharge cell that is made of barrier rib of a kind of 147nm that utilizes neon+xenon, helium+xenon-133 gas discharge generation.Because it has and simple in structurely is easy to manufacturing, high brightness, high-level efficiency, memory function, high non-linearity and greater than 160.The advantage at wide visual angle, PDP is that size is clapped display device greater than the reason newspaper that stand tall and upright of 40 inches giant-screen.And in the prior art, all must be according to the predetermined corresponding drift angle of the different resolution of PDP control, cover on basement membrane and when forming pattern at the net coating metal, need to adopt the corresponding photomask of different resolution with PDP, i.e. optical filter.And the optical filter that prior art adopts mostly to adopt thickness be that the tempering of 2-3.5mm or half tempered glass plate are as substrate; the proportion of this glass plate is 2.6; be difficult to production lightweight optical filter; on PDP, install optical filter simultaneously as simply additional; then can form air layer; cause air to be induced into the bireflection of ray; reduce contrast; also have transparent PET film directly is bonded in the method for PDP surface as lightweight, heat-resisting substrate; but the impact strength of such PDP optical filter is low, the external impact that can not protect the PDP module to be subjected to.
Summary of the invention
The objective of the invention is to overcome above-mentioned technological deficiency, a kind of lightweight PDP optical filter excellent in cushion effect is provided.
The present invention is achieved through the following technical solutions:
The plasma display panel optical filter, it is characterized in that: comprise anti-reflective film, near infrared screened film, transparent substrate and emi shielding film, described transparent substrate comprises that at least two transparent plastic resin layers and at least one place the pellicular cascade of the adhesive phase between the plastic resin layer.
The thickness of described transparent plastic resin layer is 25-250 μ m, and transmittance is 〉=80%.
Described adhesive phase comprises clear binder resin or clear binder.
Described clear binder resin is ethylene vinyl acetate (EVA) and polyvinyl butyral resin.
Described clear binder is the contact adhesive that comprises acryl compound or thermoplastic elastomer.
Described pellicular cascade is for being that the clear binder resin of the sheet form of 25-250 μ m places between the substrate membrane with thickness, then heating and at 1～10kgf/cm under 70-200 ℃ temperature
2Pressure down extruding form.
