For 3D TV, many friends may only be limited to the understanding of the screen effect, and their display principles are not well understood by many friends. For this reason, when 3D TVs enter the consumer's home one after another, we might as well take a look at the relevant information on 3D TV technology.
The so-called 3D TV is to add a special precision cylindrical lens screen on the LCD panel, and the encoded 3D video images are independently sent to the left and right eyes of the person so that the user can experience the stereoscopic feeling with the naked eye without using the stereo glasses. Compatible with 2D screens.
At present, 3D television display technology can be divided into two categories: glasses and naked-eye. 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 domestic consumer field, whether it is a monitor, projector or television, it is now required to use 3D glasses.
For spectacles-based 3D technology, we can also subdivide three main types: chromatic aberration, polarization, and active shutter, which are commonly referred to as color separation, light separation, and time division.
Color difference type 3D technology Color difference type 3D technology, English for Anaglyphic 3D, with the use of passive red - blue (or red - green, red - blue) 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 from the rotating filter wheel, and uses different color filters to filter the screen, so that one picture can produce two images, and each human eye sees different images. This method is easy to make the screen edge color cast.
Polarization type 3D technology Polarization type 3D technology is also called polarization type 3D technology. English is Polarization 3D, and passive polarized glasses are used. The polarizing 3D technology has better image quality than the color difference, and the cost of the glasses is not too high. At present, more cinemas use this kind of technology, but the display device has higher brightness requirements. On LCD TVs, applying polarized 3D technology requires TVs with refresh rates above 240Hz.
Active shutter 3D active shutter 3D technology, English for Active Shutter 3D, with active shutter 3D glasses. This kind of 3D technology is most widely used on TVs and projectors. It has relatively large resources and excellent image effects. It is highly recommended and adopted by many manufacturers, but its matching 3D glasses are expensive. At present, 3D TVs, including LG, Samsung, Panasonic, Skyworth and other brands, use active shutter 3D technology.
Wireless Access Point (AP) is a new type of wireless network device, it is a network device based on Wi-Fi technology, can convert a wired network into a wireless network, so that you can easily access the network at home, office or public places. The feature of wireless ceilinged AP is that it uses ceilinged design, can be suspended on the wall top or ceiling, and can transmit the signal to a wider range, so that users can have more space in the same building.
Second, the advantages of wireless ceiling AP
1, the advantage of wireless ceiling AP is that it can better meet the requirements of various environments, can better meet the requirements of indoor space, can better meet the requirements of outdoor space, and can better meet the multi-level coverage area.
2, wireless ceiling AP can better meet the requirements of more network users, because it can better support multiple users, and can meet the connection of a variety of network devices, such as can support the connection of computers, smart phones, tablets and other devices.
3, wireless ceiling AP can better meet a variety of network security needs, because it can provide a variety of network security functions, including encrypted transmission, network isolation, access control, content filtering, authentication and other functions, can better protect network security.
Third, the application of wireless ceiling AP
Wireless ceiling AP can be widely used in homes, offices, companies, schools, hotels, restaurants, public places and other places to meet the network needs of different places.
1, Family: Wireless ceiling AP can better meet the network needs of the family, can make the family network coverage larger, family members can more convenient access to the network at home, more secure access to the network.
2, office: Wireless ceiling AP can meet the network needs of the office, can better meet the network needs of multiple users inside the office, can better meet the network needs of multiple users outside the office, can better support the office security network needs.
3, the company: wireless ceiling AP can better meet the company's network needs, can better meet the company's internal network needs of multiple users, can better support the company's security network needs, can better meet the company's external user network needs.
Fourth, the use of wireless ceiling AP
The installation of wireless ceiling AP is very simple, only need to install it on the wall top or ceiling, and then connect it to the network interface, and finally use its configuration software to complete the installation and setup, the use of wireless ceiling AP is very convenient, as long as the network function is enabled, you can allow multiple users to easily access the network in the same building.
