What is 3D TV
3D is the abbreviation of three-dimensional, which means three-dimensional graphics. 3D LCD TV is to add a special precision cylindrical lens screen on the LCD panel, and send the coded 3D video image to the left and right eyes of the person independently to produce a stereoscopic effect, which enables users to experience the stereoscopic effect without using stereoscopic glasses. Feeling, at the same time compatible with 2D picture.
Is 3D TV good or not?
1. Advantages of 3D TV
(1) Strong stereoscopic realism and shocking visual impact;
(2) High brightness and high contrast ratio , high-definition picture, no ghosting, natural and realistic;
(3) Compatible with playing 2D/3D content, the picture can be freely converted
2. Disadvantages of 3D TV
(1) Health and safety is an urgent problem to be overcome in 3D stereoscopic display. The results of the study show that viewers are prone to eye fatigue and dizziness due to the rapid movement of their eyes back and forth when viewing stereoscopic images.
(2) The price is not cheap. It seems that it is not easy for a 3D TV to really enter an ordinary family. It is hundreds or even thousands of dollars more expensive than an ordinary LCD TV. A movie requires hours of download time, matching subtitles) and stereo glasses to form a home 3D video system.
(3) Although the public is very enthusiastic about the 3D version of “Avatar”, “Kung Fu” and other films, in fact, the current 3D film source is still very scarce.
Which is better between 3D TV and 4K TV
3d is the abbreviation of 3dimension, which means “three-dimensional”. In terms of film technology, it is stereoscopic film and stereoscopic display technology; On the order of 4 thousand pixels (ie 4096×2160). Obviously, the concepts of the two are different.
3d refers to the imaging method, and 3d TV is the abbreviation of three-dimensional image TV. It uses human eyes to observe the object at a slightly different angle, so it can distinguish the distance of the object, produce the principle of stereo vision, and separate the images seen by the left and right eyes, so that the user can experience the three-dimensional feeling without using stereo glasses.
4k refers to the size of the resolution; 4k TV refers to a TV whose physical resolution of the screen reaches 3840×2160 (QFHD) and can receive, decode and display video signals of the corresponding resolution. Its resolution is 4 times that of Full HD (FHD 1920×1080) and about 9 times that of High Definition (HD 1280×720).
In short, 3D and 4K are two different functions, and there is no question of whether they are good or not. It can only be said that you need that function more. Currently, 4K TVs have a higher resolution and better resolution. Compared with the 3D function that has been available for a long time, 4K TVs are more necessary to be considered first.
Attention for 3D TV use
1. How to get film source on 3D TV
(1) 3D channel: easy to watch, but most of the time there are no good programs to watch
(2) 3D Blu-ray Disc: The number of sources is large, and the 3D effect is the best, but the cost is high.
(3) Network download: The 3D effect is better, but the file download takes a long time.
(4) Online viewing: It is convenient to watch, the 3D effect is average, and the film source is very few.
(5) 2D to 3D: The 3D effect is poor, and it is only an expedient measure when the 3D film source is insufficient.
2. How to watch 3D movies online on 3D TV
Nowadays, 3D TVs generally can automatically recognize the standard 3D signal function. When the adaptive detection in 3D settings is set to ON When the video is displayed, it can be analyzed according to the content of the video, so that the screen can be automatically recognized; if the adaptive detection is set to off, you can also manually set the 3D to realize 2D to 3D, and you can also adjust the depth of field according to your own viewing habits. He Yukuan, and don’t forget to wear the matching 3D glasses.
How to choose a 3D TV 1. Look at the hardware
(1) Choose a brand
This is a shortcut to quickly choose a TV, big brands, technology, quality, price, and after-sales are guaranteed . At present, smart TV brands include: Samsung, LG, Hisense, Konka, Changhong, Skyworth, TCL, Haier, as well as Lenovo, Xiaomi TV, LeTV, etc. When choosing, be sure to “shop around”.
(2) Look at the configuration
Whether the performance of the smart TV is good or not, the most basic thing is to look at the “four major items”: CPU, GPU, memory, storage, these four indicators are directly Determines the performance of the smart TV:
(3) Watch accessories
The remote control of the real smart TV can do infrared remote control, touch, somatosensory, voice, keyboard input, air mouse All functions are all in one, and there is no need to pay for additional purchases at all; whether the operation is simple and convenient, a good IPTV design is user-friendly, the operation is simple and convenient, with one-key Internet access function, you can easily experience all functions with a combination of a few keys; watch the network Whether the connection methods are complete and diverse, pay special attention to whether it has the function of wireless WIFI, you can set up a home LAN wirelessly, share resources with the home computer, use wireless 3G and wireless WIFI, you can avoid pulling the network cable; In terms of interfaces, Super TV provides comprehensive, HDMI Interface, USB interface, a set of AV interface, optical fiber interface and audio output interface at the same time, of course, as a smart TV, network interface is essential.
(4) The size should be purchased according to the actual situation
The viewing distance is 2.5 meters-3.5 meters, it is more suitable to purchase 42 inches and 46 inches, and the viewing distance is 4 meters-6 meters, suitable for Buy 55-inch, 60-inch; if you want to buy a smart TV with 3D function, then you need to try to wear 3D glasses when purchasing, under the premise of normal distance and light, to see if the viewing angle is suitable, Whether you can achieve the visual effect you want, whether your eyes are uncomfortable, etc., you can purchase it according to your own needs.
2. Look at the software
(1) Operating system
Andriod system is currently the most widely used intelligent operating system, and many versions have been launched so far, perhaps many users do not know, 2.3 and previous versions are specially developed for mobile phones, version 3.0 is only suitable for tablet computers, and only version 4.0 can be installed to support smart TVs.
Therefore, when purchasing a smart TV, be sure to pay attention to whether its operating system is Android 4.0. In addition, it should be emphasized that the vast majority of smart TVs on the market that use the Andriod 4.0 system still perform poorly in terms of experience.
Since it is a smart TV, of course, it is necessary to consider the issue of upgrading. Compared with traditional TVs, smart TVs are closer to “computers”, so their update speed will be amazing. A good smart TV should be able to fully upgrade the content and operating system, otherwise it will definitely be outdated in a few years.
(2) Online Video
Smart TVs generally provide online video-on-demand functions, but “yes” does not mean “good”. Judging by the following three aspects: whether the film definition is high enough; whether the film update is fast enough; whether the film playback experience is smooth enough.
Professional video-on-demand needs to meet these four points: online video-on-demand specially designed for high-definition large screen; clearer and smoother picture; the latest video is updated in time; fast buffering, completed within a few seconds. Check whether the Internet TV has the online soft decoding upgrade function. If the encoding technology cannot be upgraded, the audio and video formats in a few years may not be able to be viewed.
(3) App Store
At present, most of the smart TV apps on the market are not only small in quantity, but most of them are directly pan-loaded from mobile phones, tablet computers and other small screen devices Yes, there is no optimization and adaptation for high-definition large screens at all, and the use effect cannot be guaranteed, and some applications may even cause the TV to freeze.
Professional smart TV applications will be specially tailored for large TV screens to ensure the best user experience. The mainstream smart TV products have done a good job in the application store, such as Hisense, Changhong, TCL, Skyworth, Samsung and other companies, most of the built-in apps are free, and users can download and use them with confidence.
3D TV price
The price of 3D TV is generally 3000-4000 yuan, and some even tens of thousands of yuan.
