As we all know, the flat paneltelevision is a new trend right now because it has the advantages of low powerconsumption and radiation. It is favor of peoples health. More and more peoplechoose flat panel television. In 2006, the global saleroom increased to fifty-eight point sevenbillions from the twenty-three billions in 2003. The parameter of flat paneltelevision is a little complicated. When people choose a television, they do feel difficult tounderstand it. As a result, the choosing of a suitable flat televisionbecomes a problem. There are five key pointsto remember when you choose a flat television. Thefirst points: the bigger size isnt the better. In recent years, there are manyflat televisions in big size and oversize with a lower price. But the oversizeor big size doesnt fit all families. The size is related to the viewingdistance. For example, the viewing distance of 32" is two meters, the 37"is two point four meters, and the 47" is three meters. Before you choosethe size of television, you should measure the distance between television andsofa. If you did not choose the right size, it could influence your vision andhealth.Thesecond points: the contrast between liquid crystal display (LCD) and plasmadisplay panel (PDP). Which one is better? In regard of power dissipation, theLCD has lower power dissipation than the PDP. The PDP has a different displayprinciple with LCD. The power dissipation of LCD is fixed if only the backlightbrightness is the same. But the PDP has higher power dissipation if the luminanceis better. The PDP has a high-contrast and clear motion graphics without trailingsmear. If you dont have a higher demand for television, the LCD is your bestchoice. But for sport fans, the PDP is the best choice because you can enjoy abetter picture effect. Thethird point: the 120Hz refreshing frequency is better than100Hz? The refreshingfrequency refers to the number of pictures can be displayed in one second. Itis said that the higher of refreshing frequency, the better of stability. Butit isnt true. The refresh rate of PAL standard television is 50Hz. Thus, the frequencydoubling is 100Hz, not 120Hz. If your television is NTSC standard, the 120Hz isyour choice because the refresh rate of NTSC standard is 60Hz. But if yourtelevision is PAL, you should choose the 100Hz. The 120Hz adopted the sametechnology with 100Hz. Thefour point: the chip of image processing. It could influence the pictureeffect. At the present, the main IC manufacturer is Trident, Genesis etc. The Trident mainly produces middle and high level products,including SVP-CX (support under 37"), SVP-PX (support above 37"),SVP-LX, SVP-WX (support above 40"), SVP-WX (support 120Hz). The Sony, Samsung,Sharp, Phillips, Konka are mainly adopted this chip. TheGenesis has a better image, but the effect of DVD is not so good. The mainadvantage is clear image with the special technology in aliasing process. Ithas a good stereovision and coloration. The mainly television brands which usethe chip are LG, Toshiba, Hisense, TCL and so on. Thelast point is the choice of panel. The liquid crystal panel can be divided into IPS and AVpanels according to the display technology. The IPS has fast response time,stable picture, big visible angle, lower cost and excellent motion picture. Thedisadvantage of IPS is electricity-guzzling. You could ask the seller toconfirm if the television is IPS before making a decision. Exceptfor the above five points, you should be care for some pretty details. Thehigher of brightness, the color is a light white not ash-colored. High contrasthas a larger dynamic range. Finally, I do hope that the above knowledge oftelevision can help you to choose a best television in future.
