LCD TV
Is a major problem, which has important value make sense of the parameters will not be business concept of playing the game "Fudge", buy the right products.
<BR> With
Flat Panel TV
Popularity, many consumers on the plate
TV
Several key parameters have a certain understanding, many people buy television as a basis for determining when the performance is good or bad TV. In fact, most consumers know that these parameters only affect a small part of the television performance factors, especially in LCD, plasma
Panel
After mass production, only that a few suppliers, the market circulation of raw materials used are basically the same, it is impossible to judge from these parameters television properties. This issue, we are a few from the television consumer is often overlooked, but it is very important to use the performance to talk about some of the main reference for the TV to buy.
<BR> " " of: Full HD is the high-resolution still images
<BR> Information currently on the market high-definition digital TV standard, more reflected in the resolution of the static image, that is the definition TV is the main display high-definition television signals have the capacity. But for TV receiver HDTV signals in real time, in the exercise under the screen at what resolution, whether or HD, and no substantive requirements.
<BR> Truth:
TV
Definition in fact consists of two levels, namely, static and dynamic definition clarity. As the name suggests, static definition refers to a static screen TV in the display clarity, and dynamic definition refers to the dynamic screen TV in the display clarity. Store in the current LCD TV is broadcast in most cases the static picture, this does not show the real HD. The time of purchase, consumers make the best broadcast to the Purchasing Guide requirements of dynamic images, and the sooner the better, if no blur, no dithering, is the real full HD.
<BR> In addition, the "full HD" needs to satisfy two conditions: 1920 × 1080 physical resolution, 16:9 screen ratio. Some manufacturers call "Full HD LCD TV" actually it has only 1366 × 768 resolution.
<BR> " " Two: LCD TV "soft, hard screen" when the dispute
<BR> An error saying now is very common in the Marketplace Shopping guide: the so-called hard-screen LCD is a high surface hardness plus a layer of protective film of transparent resin material. Meanwhile, hard-screen heat problems are exaggerated: Hard-screen LCD TV, etc. plus a protective film due to heat unevenly, the last screen expansion and contraction, will greatly affect the quality.
<BR> Truth: expert explained that the reason hard hard screen (the touch without watermarks), not outside in the LCD screen protective film attached to resin, but by the LCD panel determined the molecular structure. By touch at the time, hard screen can basically desired. Moreover, when the rolling bumps, hard LCD screen will not appear jitter, blur the issue, showing a better effect.
<BR> The screen heat dissipation through the authority of the test, the hard surface of the heat screen and the soft surface of the heat-screen comparison, little difference from the temperature value.
<BR> " " The Third: 120Hz what magical powers?
<BR> Now many LCD "Sports HD" New to strive to make efforts in this regard. Shopping guide introduction, the highest refresh rate of LCD TV 120Hz, which eliminates the formation of human vision to remain fuzzy temporary illusion, effectively increasing the dynamic definition.
<BR> Truth: the screen refresh frequency is the number of times per second the screen is refreshed, that can show the number of images per second. LCD TV's refresh rate general is limited to 60Hz, that every 60 seconds to display a fixed screen, and then the next 1 / 60 seconds to replace.
<BR> Called 120Hz, is calculated using Photoshop in the interpolation theory, produce a range of the first 1 / 60 and the second 1 / 60 seconds the screen, which for now is very easy to processor performance , and this effect was relatively good. But doing so makes the picture "too smooth", and this is too smooth and delicate our lack of understanding of the degree to screen, or manufacture of the 1 / 120 seconds before the screen interfering with picture quality.
