In 2010, 3D TV was popular in the color TV market with the grand release of "Avatar". At present, not only Samsung, Sony, LG, TCL, Hisense, Konka, Skyworth, Changhong and many other color TV manufacturers have launched 3D-enabled tablets. TV, and the outstanding three-dimensional picture effect, has gradually been recognized by the majority of consumers.

For 3D TV, many friends may only be limited to the understanding of the effect of the picture, and many of their friends are not very familiar with the display principle. To this end, while 3D TVs are entering the consumer family, let us first take a look at the relevant information on 3D TV technology.
The so-called 3D TV is a special precision cylindrical lens screen on the LCD panel. The encoded 3D video images are independently sent into the left and right eyes of the person, so that the user can experience the stereoscopic feeling with naked eyes without using the stereo glasses. Compatible with 2D graphics.
At present, 3D TV display technology can be divided into two types: glasses type and naked eye type. The naked eye 3D is currently mainly used in public business occasions, and will be applied to portable devices such as mobile phones in the future. In the field of household consumption, whether it is a monitor, projector or TV, it is now necessary to use 3D glasses.
For the glasses-type 3D technology, we can subdivide three main types: color difference, polarized type and active shutter type, which is commonly referred to as the color separation method, the light division method and the time division method.
Chromatic aberration 3D technology
Chromatic 3D technology, English Anaglyphic 3D, with passive red-blue (or red-green, red-green) filter 3D glasses. This technology has the longest history, the imaging principle is simple, the implementation cost is quite low, the cost of glasses is only a few dollars, but the 3D picture effect is also the worst. The color difference type 3D first separates the spectral information by the rotating filter wheel, and uses different color filters to filter the picture, so that one picture can produce two images, and each eye of the person sees a different image. Such a method tends to cause color cast at the edges of the picture.
Polarized 3D technology
Polarized 3D technology is also called polarization 3D technology, English is Polarization 3D, and passive polarized glasses are used together. The image effect of the polarized 3D technology is better than that of the color difference, and the cost of the glasses is not too high. At present, many cinemas adopt such technologies, but the brightness of the display device is relatively high. On LCD TVs, the application of polarized 3D technology requires a TV with a refresh rate of 240 Hz or higher.
Active shutter 3D technology
Active shutter 3D technology, English Active Shutter 3D, with active shutter 3D glasses. This 3D technology is the most widely used on TVs and projectors, with relatively large resources, and excellent image effects. It is highly respected and adopted by many manufacturers, but its matching 3D glasses are more expensive. At present, 3D TVs, including LG, Samsung, Panasonic, Skyworth and other brands, use active shutter 3D technology.
Drum type Rice Cooker
Features
This type rice cooker is famous with drum type appearance, which is easy operation and easy clean.
There are two type of inner pot , one type called white pot which is without non-stick but cheaper price .another one called non-stick pot is polished with emery, Also there are two type non-stick with different price ,it`s depending on different demands to use.
And the inner pot cannot be burned on the stove, which will make the pot transfigured and bad contact with the heating plate. While cooking , the heating plate or the fuse is most likely to be burned for the bad contact of the inner pot and the heating plate, Besides, make sure to dry the pot before putting into the outer shell of the rice cooker ,or else the drops of water flowing on the heating plate, will make the heating plate rusted.
Applications
Many peoples are used drum type rice cooker for congee and soup, some of peoples are prefer to use this type rice cooker for steaming.
