Black power: energy-saving guidelines for technical direction of 3D Internet – Internet TV, LCD TV – Network Appliance Industry
Editor's note: in 2009
Home Appliances Consumer electronics market, technology colorful, black areas, including the first industrial side-in white LED (Light Emitting Diode) backlight,
Internet TV , Plasma energy technology; digital TV, including high-definition set-top boxes, digital television middleware technologies;
White Areas, including energy conservation, and preservation of health, frequency conversion technology. These techniques this year, home appliances, consumer electronics industry has played a positive role in promoting, giving consumers more and more useful features, but also to the Chinese home appliances, consumer electronics industry's voice in the global market greatly increased. Technology led the Chinese home appliance, consumer electronics industry, there is reason to be our focus of attention.
LED backlight From the process design point of view, white LED (light emitting diode) direct type structure is the most likely alternative to traditional LCD backlighting application form, its technical difficulty and the need for product design changes made to the lowest. Therefore, the source application model to become the most popular mode of LED TV applications.
Side light type backlight module will spot-light settings specially designed light guide plate in the side as the light source, using the LED fewer teeth. The light guide placed side by light, LED brightness by the teeth and the restrictions will still be light uniformly dispersed throughout the plane, it will form when
Panel The larger the area, the light source luminance using the more limited.
Due to LED backlighting on the product side, so only need to add back to liquid crystal light guide can be very thin thickness of the appearance of products, such as Samsung's new LED 6000/7000/8000 series is used in Edge backlight module. White LED edge lighting and backlighting
LCD TV With thin, simple structure, advantages, side light type backlight is generally very thin, but small source of light utilization, and utilization of the smaller thinner, the largest of about 50%.
Present direct type-in white LED and white LED side has a representative firm involved. Such as push direct type white LED LCD TV products and chips are
SHARP , Skyworth, Hisense, etc., push the side-in white LED LCD TV products and chips are Samsung,
Sony With the other side. RGBLED backlight is the birth of time, a technique earlier. RGBLED through red, green, blue RGB LED into white light modulation, with the best optical properties.
RGBLED the advantages of television mainly in color performance and contrast two ways: As a result of RGB primary colors independent light emitting device, so RGBLED large range of TV's color gamut to achieve NTSC (U.S. standard TV standard) 120% or more Some well-tuned models can even reach 150% of color gamut, fully meet or exceed the standards of the plasma TV.
Editor Comments: aside technical one is better not say that we look at the market, led by Samsung, White LED edge lighting technology to achieve the first large-scale production, not just in Edge White LED technology, competition, victory is Samsung LED TV market competition and achieved good start. In contrast, direct type white LED technology, the lead company??? Sharp were busy pushing product forget in combination with other advantages, slightly less than the market strategy. The best RGBLED display technology has not been a good way as to overcome the problem of high costs, but reduced to a number of companies prepared to give up technology. This once again proves that advanced technology is very important to the industrialization of the more important.
Internet TV
In the United States earlier this year the International Consumer Electronics Show (CES), the participating company sent out a strong signal ????? combination of television and the Internet era has arrived. The integration of television and the Internet more than the required industrial chain links have gradually up in recent years. Internet service providers, equipment manufacturers, software and semiconductor companies are working together to introduce different solutions to try to interconnect between television and the Internet, and media format compatibility.
The e-commerce company in China offers quality products such as red diode laser module 635nm , red diode laser K65S08M-2.80W, and more. For more , please visit laser module today!
