What is the difference between BenQ VK3211 s LCD TV and VJ3215?

Plasma TVs (PDP) and LCD TVs (LEDs

LCD) are both flat-screen TVs, and they are like twins, although they are very similar on the surface, but they are very different in nature. The biggest difference between the two is that they use different panels, which means that their imaging principles are very different. Plasma TVs rely on high voltages to activate a special gas in the imaging unit, causing it to produce ultraviolet light to excite phosphorescent substances to emit light.

LCD TVs, on the other hand, use an electric current to change the structure of the crystals in the thin-film transistors on the LCD panel, so that it can be visualized. In addition, plasma TV and LCD TV also have their own characteristics, such as plasma TV is cheaper than LCD TV in large size, and LCD TV has advantages in power-saving performance and static display resolution, and the service life of the two is basically the same.

Plasma TV refresh speed is faster than LCD TV, display dynamic image effect better, color and hierarchy are better than LCD, wide viewing angle, more suitable for TV, but energy consumption is higher than LCD TV.

LCD TV displays fast-changing dynamic images with tailing phenomenon,Display dynamic image resolution is low,**Small viewing angle,Can only sit on the front of the screen**,So it is more suitable for computer monitors,Energy consumption is lower than plasma。

To put it simply. Plasma is good for watching TV. Because plasma pixels are self-emitting. The color is positive.

There is no trailing in the image.

The brightness is soft and not dazzling.

There is a saying that makes sense: the layman looks at the liquid crystal, and the insider looks at the plasma.

Hello, 1 ntsc system.

The NTSC system is also known as the grace system. It is named after the abbreviation of the National Television System Committee. This system solves the problem that color TV and black-and-white TV broadcasting are compatible with each other, but it has the disadvantages of easy phase distortion and unstable color.

2 pal.

The PAL system is also known as the account system. It is to overcome the sensitivity of the NTSC system to phase distortion, PAL is an abbreviation of the English Phase Alteration Line, which means line by line inversion. PAL effectively overcomes the color change caused by phase distortion, phase distortion is not sensitive, the image color error is small, and the compatibility with black and white TV is good, but the encoder and decoder of PAL are more complex than those of NTSC, and the signal processing is more troublesome, and the cost of the receiver is also high.

3 SECAM system.

The SECAM system is the SECAM system. It is an abbreviation of the French sequentiel couleur a memoire, which means "to transmit color and store in order". The modulation method of SECAM chromaticity signal is different from that of NTSC and PAL, so it is not afraid of interference and has good color effect, but its compatibility is poor.
