However, if the visible light transmission rate, EMI shielding filter to see through the screen will be dark. So. General requirements for visible light transmittance to 60 or more. The near infrared shielding performance is also very important one. In recent years, most household appliances use the remote control operation ashamed. Remote control is the issue of near-infrared light. Xin to. Such as the PDP was sent out to near-infrared wavelengths. Zhou Xiao is possible to make the appliance malfunction. So. This must also be shielded near-infrared. EMI shielding shake the near-infrared filter shielding rate required to achieve 80 or more. Near-infrared shielding substrate commonly used in its structure, then, revolves around adding Jing stabbed near infrared absorption method really only need a shield 9O0 l100nm the near-infrared. The transmission through the adjacent wavelength bands 400 - 700nm visible light. So. Jing near-infrared absorption of molecular structure and stability is very important. 40-inch PDP screen size in 50O �� 900mm or more. So 1998 will be 7-8 of Filter is used as filter 2-3mm thick tempered glass or acrylic base, made of polycarbonate plastic, it can play a role in anti-burst. EMt shielding filters safety and not in front of the PDP, in order to prevent the indoor scenery greet, requiring that their display should be the same as the usual anti-reflective properties. Anti-reflective properties of the value to be lower than 5 below. EMI shielding filter divided by 2 kinds of structural materials, electromagnetic shielding method divided by 2. 4 species. Substrate materials include glass and plastic, the thickness were about 2-3mm. Caused by the thermal expansion of glass is small, even if the connection will not be installed to display and glass deformed t have the advantage of higher grade than the plastic, downside is heavy. 40-inch display glass used in about lOkg, may affect the display of light. Plastic materials in accordance with its transparency, weather resistance characteristics, the use of propylene-based (PMMA) or excellent impact resistance polycarbonate (PC). These materials do not obstruct the light of the monitor, and has the advantage of cheaper prices than glass. However, a large thermal expansion coefficient than glass. Therefore, the installation of the PDP to heat large surface,<a href="http://www.uggboots-jp.org" target="_blank" class="postlink">UGG ブーツ</a>, prone to image distortion caused by deterioration or resulting Newton rings. However, the response to these problems. The PDP manufacturers are trying to reduce the degree of surface Kun, it is likely to be resolved or eased in the future. Electromagnetic shielding methods include the use of conductive fibers, metal loops and full screen method to impose I1D or silver film method. Sieve method electromagnetic shielding of the biggest advantages is good. However,<a href="http://www.converse-solde.com/chaussures-si-cle-converse" target="_blank" class="postlink">Converse chaussures</a>, due to screen size and pixel pitch of the relationship, prone to ripple fringes. Pursuit of high electromagnetic shielding properties, such as excessive widening of screen width or pitch too narrow, there will be transparency decreased. In contrast, transparency means the best film,<a href="http://www.oakleysunglassess.org" target="_blank" class="postlink">oakley sunglasses</a>, but not as good as electromagnetic shielding screen mode. And the electromagnetic shielding performance and wavelength. Especially in the high frequency shielding performance decreased significantly. To this end, developed a combination of the above materials to the various structures of the EMI shielding filter. Electromagnetic shielding from visible light transmission Gu compatible with the point of view,<a href="http://www.uggsbootsitalia.org" target="_blank" class="postlink">ugg italia</a>, lithography and additives (plastic or glass), and other San fine mesh type best. On the way in which companies to use lithography for electromagnetic shielding mesh methods, in order to seek high-shielding material is a good selection of lightweight transparent plastic, and Li Jing rejection of the Company's bonding love technology and coating technology wiring board technology , is studying the relics of the necessary conditions to meet PDPTV screen with high magnetic dip, transparency and EMI shielding properties of near-infrared shielding filter. The visible light transmittance of electromagnetic shielding, screen dip of near-infrared, anti-reflective and image clarity reached 47dB, 64,80 or more,<a href="http://www.abercrombieoutlets.org/abercrombie-hoodies" target="_blank" class="postlink">Abercrombie Hoodies</a>, 5 or less and 3.7.
