< BR> In the just-concluded Beijing Cobo Conference, Panasonic shows a new 8-Series
Plasma TV
New, according to Panasonic’s propaganda, the dynamic Panasonic 50PZ880C more than 900 lines can be more clarity. After visiting a friends advice I found the dynamic definition of the problem, the users of the doubt, full HD
LCD TV
Can achieve 1080P, Panasonic Full HD Plasma TV, just how more than 900 line on the road? Is Full HD Plasma-definition LCD TV is also lower than that?
<BR> Very representative of the users of the doubt, in fact, Panasonic 50PZ880C is full HD models, Full HD LCD TV resolution better than low, especially in the dynamic images, the resolution much higher than the LCD TV. To clarify this problem, we need to find out some basic concepts.
<BR>
Flat Panel TV
Resolution does not equal clarity
<BR> General, we friends often confuse the TV resolution and clarity. In most cases, so that will not find anything wrong with the problem, the higher the resolution, the higher the resolution, so we tend to think that this is the same concept. In fact, the resolution and clarity are two totally different concepts.
<BR> In
CRT
, The mock-definition television signals using the TV line image concept, the measurement unit is the high and low-resolution TV lines. For CRT TV, the standard measure of definition that is TV cable.
<BR> Emergence of digital television signals, high and low resolution images are no longer in TV lines as the measure, but the use of the concept of resolution, such as
DVD
Shows a resolution of 720 × 480, resolution of digital cable TV 720 × 576, high-definition programming resolution is 1920 × 1080.
<BR> Flat-panel TV appears, do not use the concept of television lines. As LCD and plasma TVs are the point of display, it also uses the concept of resolution. Resolution 26-inch LCD TV for more than two main: 1366 × 768 and 1920 × 1080. Plasma TV’s situation is more complex, the basic resolution is 852 × 480 and 1024 × 768, Hitachi also 1024 × 1080; HD resolution models of 1366 × 768, Hitachi, compared with 1280 × 1080; Full HD model are 1920 × 1080.

TV line is calculated
<BR> To find out the concept of TV lines, but also make clear whether the concept of lines, the TV screen, two black and white vertical line, called the two lines. However, this line is not that television lines, television cable concept is to measure the horizontal direction along the section of the screen length, it is equal to the vertical screen height, which contains the lines is equivalent to its TV line. For example a 16:9 TV, the level can display 1920 lines, the value of its TV line for the (1920/16) × 9 = 1080 TV lines.
<BR>
Flat-panel TV line resolution and the relationship between television
<BR> Theory, a pixel on the LCD TV up to display a line, 1920 × 1080 LCD TV, the best state, can display 1920 black and white lines. TV lines in accordance with the formula, that is 1080 TV lines. Indeed, this value is only theoretical calculations, the actual display resolution, and can not reach so high. For example the actual play of images, there is a line just in between two pixels, this line can not be clearly displayed on the LCD TV, HD is reduced.
<BR>
Dynamic images and dynamic resolution
<BR> Above, is a static screen mode, if the display dynamic images, the more powerful lower-resolution television. In particular, LCD TV, to be considered as liquid crystal response speed, tailing occurs, thus substantially reducing the image resolution, while the absence of the plasma tail problem, dynamic resolution is relatively high.

Test Method for Dynamic Definition TV
<BR> Dynamic definition standard by China Video Industry Association to develop, not only applies to plasma TVs, LCD TVs also apply. Plasma dynamic image definition digital TV test signal measurement method used is full HD format, provided the speed of a moving image is 4.5PPF, that move once every 8.5 seconds the screen. Another speed is 5.0PPF, mobile time 7.7 seconds. By visual inspection to determine whether to maintain a clear picture.

<BR> Same 1920 × 1080 images, Panasonic Plasma TV 50PZ880C dynamic definition can reach more than 900 lines (in this case TV lines), while the 600 line of LCD TVs to be lucky.
