Full HD LCD TV is not the only new technology Xiang Jie – LCD TV, Flat Panel TV – household applianc by jekky
< BR> In 2007,
LCD TV
Developed rapidly. Entered after 2008, high-end LCD TV’s new technologies are emerging, some past technical terms not familiar to consumers whom are curious. In the eye enough to earn enough after what technology is actually able to enjoy it? Standing

Updating the crossroads of you, is not some "blind" it? In order to access to these technologies, but also what the surrounding conditions for co-ordination? You understand and is willing to put in it? With this series of questions, please essays to enter today’s article!
<BR> Full HD is not the only choice
Throughout the present <BR>
Flat Panel TV
Market, WXGA of 1366 Ã- 768 pixel Lcd Screen has become "second-class" goods, and have the physical resolution of 1920 Ã- 1080 Full HD LCD FULL-HD
Panel
LCD TV LCD TV nowadays has become the mainstream configuration. Consumers visiting the store as part of the time, however, are high-definition 1366 Ã- 768 models do not look at more.
<BR> While the standard 1920 Ã- 1080 Full HD LCD TV has become the mainstream LCD TV, but FULL-HD Plasma is also more and more there have been 50 inches of products. When you have a full HD display flat-panel TV, your TV signal source while maintaining the number of standards? Currently most consumers at home or watch digital cable programming, the digital video formats up only 720 Ã- 480 (NTSC) and 720 Ã- 576 (PAL) two, and
DVD
Play the definition flat, in fact, are even lower than the format of the signal source to be used. Therefore, from the resolution point of view, any one of the current flat-panel TVs are sufficient to deal with the current digital cable TV source resolution. If the figures point to point transmission, when the pixel flat-panel TV just when the resolution is 720 Ã- 576 is best. This keeps the signal pixels and the pixels of flat panel TVs-one correspondence, there is no loss.
<BR> If the display pixels more than the intrinsic signal resolution pixel, so that these extra points do not light on it, do so entirely easy, actually watching, just feel a little smaller than the screen. If you need to make the screen full-screen, flat panel TV’s internal processing circuitry necessary to enter the digital signal to a TV point of re-separation, if the input level is assigned to a level of 720 pixel screen has 1920 points, it Enter the one about to take up screen pixels 2.7 pixels to display. Thus, making the display image quality and clarity should be dropped. With the increase in display technology, different brands of flat-panel TVs have used different algorithms to compensate for this phenomenon, but it is just another screen to minimize the loss, can not fundamentally solve the problem. Simply think of can understand this principle.
<BR> Pixel display many advantages, only reflected in the screen is more detailed, less grainy, not for viewing clarity improving relations. Under normal viewing circumstances, higher than the signal source with high-resolution screen format definition television programs, there is no practical advantages.
<BR> How to play full HD that advantage? Unless you re-install high-definition video
Washer
(Blu-ray player), or through the local cable TV operators launch digital HDTV programming. But this is not the ordinary user of consumer goods, and full high-definition television is the situation everywhere are compared to almost none.
<BR> 10bit LCD panel drive technology over 1 billion colors is another way of saying. The current use of 8bit monochrome LCD TV quantify, a single color will have 28 = 256 level. The number of Color Display is 28 Ã- 28 Ã- 28 = 16777216 colors, that is 16.77 million. If using 10bit quantization, there is 210 Ã- 210 Ã- 210 = 1073731824, or over one billion color display.

<BR> Key to the technology aspects of the interface wiring, when for 10bit quantization, the driver IC and the timing control IC chip to be oriented to achieve 10bit, which is not technically difficult, but the chip’s wiring to increase 25%. Therefore, to reduce wiring, lower prices is the key.
Sony
In this regard, the technology already in place, can be a practical.
<BR> But one billion colors on the LCD the practical significance of the different LCD TV’s technical staff have different views, because the liquid crystal orientation needs of the actual applied voltage when the voltage is converted into numerical control has been more than 8bit 1bit level when the voltage difference also large pressure difference is too small will not make the liquid crystal molecules are reactive. In other words, dynamic screen, 8bit have shown not in place. In fact, quantitative look at the same 8bit LCD TV
Plasma TV
In the static and dynamic color screen when the level can understand.
<BR> Current TV signal even in high-definition TV programming is only 8bit quantization, therefore, not 10bit digital video signal of. In this case, either to re-quantify the signal source that has the digital signal processing, or 10bit models after the installation of digital interface able to quantify the signal raised to 10bit 8bit digital signal processing circuit. And the latter is closer to it which, Sony X300A and W300A have this ability. But to achieve, or have prerequisites.
