Description
Technical field:
The present invention is relevant with the optical filter in the display device, and is special relevant with the optical filter with anti-electromagnetic radiation and filtering functions in the plasma scope (PDP), relevant with the plasma display that adopts optical filter.
Background technology:
The described technical background of the application, be at publication CN1509490A, the further improvement invention of doing on application number 200410069275.7,01804419.0 and my application number 200610022680.2,200610022679.X, 200710048369.X, 200710048370.2 the technical foundation.
Because of PDP display filter major function is in order to shield harmful electromagnetic interference wave that display sends, it also is the EMI shielding, the absorption of ultraviolet light (UV), the reflection and the shielding of near infrared light (NIR), and the absorption of the yellow characteristic light (about 590nm wavelength) that sends of display neon light, make that TV watching is safer, health, image is more clear, color is more bright-coloured.The series of patents technology of the applicant's application, mainly be plating low-refraction (relatively high-index material) metal oxide and high index of refraction (relatively low-index material) metal oxide of the basic rete of conduction in the both sides of its film symmetry in order to silver, form the film system of 13 layers or 17 layers, this rete has the EMI function of shielding, the UV absorption function, the NIR reflection function, optical filter has 50% to 70% transmittance at visible light wave range, coating or the compound yellow characteristic light (about 590nm) that neon is sent that contains have the dyestuff of absorption function and adjust colour temperature and the dyestuff of color and transmittance or the resin bed or the plastic membranous layer of pigment on optical filter, can regulate transmittance reaches between 30% to 45%, tone meets the colour TV international standard, the coloured image that display is sent has high definition, high-contrast, the picture quality of the tone value that antiradar reflectivity etc. are correct, the optical index of the coatings of 13 layers or 17 layers wherein, particularly survey a of the tone value under the reflected value situation, b value and adding dye resin layer are afterwards to the green light wave band, a under the absorbing state of sodium yellow wave band and the about 590nm of yellow characteristic light, the combination of b value has material impact, generally can regulate the X of tone value with the concentration of dyestuff, Y value and corresponding a, the b value, make tone X 0.2800～0.3200, the Y value is 0.3000 to 0.3400; Surveying under the reflected value situation, a value is preferably between-1 to 10, and the b value is between-1 to-20.
Optical filter uses copper mesh to come the shield electromagnetic interference ripple, use UV, NIR and the absorption of yellow characteristic light or the film of reflection function to be combined to form the optical filter function, reach standard compliant EMI screening ability and tone value, this is a kind of method, as a large amount of disclosed technology status in the aforementioned patent applications, do not state tired at this.
The blooming that adopts film plating process to form 13 layers or 17 layers reaches absorption and the reflection function of EMI screening ability and UV, NIR, increasing one deck again has receptivity also by adding the further dye resin layer of toning of dyestuff to yellow characteristic light, is again a kind of effective and low technical scheme of cost.
But because applicant's scheme mainly relies on the optical coating layer combination dye resin of 13 layers or 17 layers to reach above-mentioned functions and toning, because the yellow light absorbing dye in the dye resin layer has specific light wave absorption characteristic, therefore the array mode of two tunic layers has tangible influence to a, the b value (mainly under reflection case) of tone value again.If this dye-resin directly is coated on these 13 layers or the 17 layers of coatings, the face of watching of optical filter is made test surfaces, the a value is between 14 to 16, color is red excessively partially, when televisor does not use, optical filter (panel) shows red partially, uses copper mesh method ratio to produce optical interference with optical filter, makes the consumer produce abnormal sensory to display panel.At interval arbitrarily layer of transparent resin bed or glassy layer in coatings and dye resin layer, test equally again, between a value can drop to 8 to 12 even lower, red partially obvious improvement.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, coating technique is promoted, the plasm TV and the optical filter that provide better, cost are also lower, providing a kind of can reduce cost greatly, the production efficiency height, the intensity height, the transmittance height, anti-electromagnetic radiation and filter effect are good, and plasma display is red and green is more bright-coloured, long service life, have the optical filter of anti-electromagnetic radiation and filtering functions.Another object of the present invention is for a kind of plasma display of this optical filter of usefulness is provided.
