How Do I Choose the Best 3D Television?
It is a TV equipped with 3D functions, a fully open platform, ten-core "sharp core" technology, and an operating system. Not only has the realistic and shocking viewing effect, but also loads "unlimited content, unlimited applications". With the increasing demand for audiovisual, experts predict that 3D smart TVs will become the new mainstream, and major color TV manufacturers are targeting 3D smart TVs, such as Konka, the first smart TV in China, and recently launched 3D smart TVs. The product perfectly combines the OMi operating system and the ten-core "sharp core", and has three industry-leading technologies of "LED", "3D" and "smart TV".
3D Smart TV
- It is equipped with 3D functions, a fully open platform, ten-core "sharp core" technology, equipped with
- Compared with 2D TV, the visual impact is shocking, natural and realistic, high brightness, high contrast, high definition picture, bringing consumers the ultimate viewing experience.
- In terms of platform and function, 3D smart TV has a strong advantage. Take Konka as an example. The perfect combination of its 3D smart TV and "ten-core sharp core + OMi system" can not only revolutionize the operating system,
- The prospects for 3D smart TVs are endless. A data from a research organization shows that in 2010, global 3D TV shipments reached 3.4 million units, with a market penetration rate of 5%. By 2014, shipments will exceed 90 million units, and the proportion of shipments will increase sharply to 41. %.
- The 3D color TV market is booming. Aiming at the two major bottlenecks of scale and scarcity of film sources, domestic color TVs have launched a new round of fighting to break through. For example, Konka announced that it will lay out more than 50% of its 3D products in production. Konkayu
- The development of 3D smart TVs will bring consumers' movie viewing experience to another stage, let consumers experience more realistic effects, and also bring the competition in the color TV industry into a new era. At the same time, the expansion of 3D TV scales is most direct in bringing price benefits to consumers. During the Asian Games, the drop of 3D TV for many domestic and foreign brands ranged from 3,000 yuan to 5,000 yuan, with the highest drop reaching 7,000 yuan, with an average drop of 30%. This is also the third round of price cuts for 3D TVs in the past six months. Zhong Yikang analyst Peng Xiandong told reporters that the current 3D TVs are mainly 46-inch and 55-inch two sizes. After that, medium-sized products such as 40-inch and 42-inch TVs will enter the market. Prices will be further reduced and consumer choices will continue. increase.
- 3D display technology can be divided into two types: glasses and naked eyes. Naked eye 3D is currently mainly used in public business occasions and will also be applied to portable devices such as mobile phones in the future. In the field of household consumption, whether it is a display, a projector or a TV, it is now necessary to use 3D glasses.
- Do you know what the mainstream glasses 3D technologies are?
- In the glasses-based 3D technology, we can subdivide into three main types: color difference, polarized, active shutter, and non-flash, which are commonly referred to as color division, light division, and time division.
3D Smart TV Color Difference
- Color-difference 3D technology, English is Anaglyphic 3D, and passive red-blue (or red-green, red-cyan) color filter 3D glasses are used together. This kind of 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 a rotating filter wheel, and filters the screen with different color filters, so that one image can produce two images, and each eye of a person sees a different image. Such a method is likely to cause color cast at the edges of the screen.
- Due to the poor effect, the color difference type 3D technology is not widely used.
3D Smart TV Polarized
- Polarized 3D technology is also called polarized 3D technology. Polarization 3D is used in English. Passive polarized glasses are used together. Polarized 3D technology has better image effects than chromatic aberration, and the cost of glasses is not too high. At present, more cinemas also use this type of technology, but they have higher requirements for the brightness of display equipment.
- Polarized 3D uses the principle of "vibration direction" of light to decompose the original image. First, the image is divided into two groups of vertically polarized light and horizontally polarized light. Then, 3D glasses use polarized lenses with different polarization directions. In this way, the left and right eyes of a person can receive two sets of pictures, and then synthesize a stereo image through the brain.
- Currently in the polarized 3D system, there are three mainstream types in the market: RealD 3D, MasterImage 3D, and Dolby 3D. RealD 3D technology has the highest market share and is not affected by the type of panel. Restore the 3D image. On LCD TVs, the application of polarized 3D technology requires the TV to have a refresh rate above 240Hz.
- Currently, LG, Konka, TCL, Hisense, Skyworth and other brands use polarized 3D technology.
- Cons: Half the resolution
3D Smart TV Shutter
- Shutter 3D technology, English is Active Shutter 3D, used with active shutter 3D glasses. This 3D technology is most widely used in televisions and projectors, with relatively more resources and excellent image effects. It is respected and adopted by many manufacturers, but its matching 3D glasses are more expensive.
- Shutter 3D mainly achieves the 3D effect by increasing the refresh rate of the picture. By dividing the image into two frames, two groups of pictures corresponding to the left and right eyes are formed. Synchronous control of the left and right lens switches of shutter-type 3D glasses enables the left and right eyes to see the corresponding picture at the correct moment. This technology can maintain the original resolution of the picture, so that users can easily enjoy true Full HD 3D effects without causing the picture brightness to decrease.
- In general, the refresh frequency of a 3D LCD TV screen must be above 120Hz, that is, the left and right eyes can receive images with a frequency above 60Hz to ensure that users can see continuous 3D image effects without flicker.
- At present, 3D TVs launched by Samsung, Panasonic, Sony, Haier, Sharp, Changhong and other brands use active shutter 3D technology.
- Disadvantages:
- 1. After putting on the glasses, the brightness decreases more;
- 2. The opening and closing frequency of 3D glasses is different from that of fluorescent devices such as fluorescent lamps, and the viewing comfort is low in bright rooms;
- 3. The opening and closing of the 3D glasses shutter is not completely synchronized with the left and right images, and crosstalk ghosting will occur;
- 4. The viewing angle of shutter 3D LCD TV is small;
- 5. The price of shutter 3D glasses is about 1,000 yuan, which is relatively expensive, and requires the installation of a battery or charging.
3D Smart TV does not flash
- The non-flashing 3D TV method is the closest to our natural approach. Just like enjoying a live 3D image in a movie theater, you can watch two images at the same time and stick a special film that separates the left and right images on the 3D TV surface and glasses. The left and right images are separated by the TV and sent to the glasses at the same time. After filtering the glasses, the left and right images are separated and sent to each eye. The brain then synthesizes the two images to make people feel 3D stereoscopic. Features of non-flashing 3D: In terms of viewing angles, non-flashing 3D is not a problem when viewing within the recommended viewing distance. For example, apart from standing, sitting, or watching TV in a very abnormal posture within one meter, there is no problem when watching within the recommended viewing distance of 3D TV.
- Disadvantages: Can not reach 1080p video playback is 540p, 3d effect is not good.
- Advantage
- First, there is no flicker, which can reflect 3D images that make the eyes very comfortable. Non-flashing 3D is not powered and can be worn comfortably without any flicker. So you can enjoy 3D images that make your eyes very comfortable. Looking at the actual measured flicker data, we can know that the data is almost zero, and no dizziness will appear.
- Second, the viewing angle is wide. As long as the non-flashing 3D TV is viewed within the recommended distance and viewed at any angle, its picture effects and color expression are not discounted, and you can enjoy the perfect shocking 3D without angle restrictions. image.
- Enjoy 3D images with light and comfortable glasses. Non-flashing 3D glasses are lightweight and reasonably priced, and jacketed glasses can also be used comfortably by those wearing glasses.
- A 3D image with no overlapping images. The screen overlap phenomenon occurs because the right image enters the left eye or the left image enters the right eye. The special film used for non-flash 3D separates the left and right images to reflect the 3D image, so the screen overlap phenomenon does not occur. Enjoy the three-dimensional image that seems to see a real real object. By actually measuring the overlapping data of the screen, we can know that the non-flash 3D overlapping data is at a level that humans cannot perceive.
3D Smart TV Technology Comparison
- The polarized 3d picture cannot achieve the high-definition effect, the picture is a bit fuzzy, and the three-dimensional effect is poor. It cannot reach the pure 3d effect, which is only 2d and a half. If the position of the TV is not right up and down, exceeding 10 °, the polarized type is easy to ghost. But the benefit is not flickering. The shutter-type picture is good, high-definition effect, the glasses can be charged when plugged in the TV, there is no inconvenience, the battery is small, there is no detection agency to detect radiation, all come out. If you turn off the fluorescent lamp at night, you can't feel the flicker, the flicker itself is the result of the interference of the fluorescent lamp.
- If you want to pursue a 3d effect, buy a shutter type, if you want to buy a pair of glasses with light, so that means 3d, use polarized. personal hobby.
