In recent years, with the continuous upgrading of flat-panel television technology, the size has increasingly tended to be large-screen, and many consumers are blindly pursuing large-sized, but they neglected the viewing distance of the living room itself. The final television is placed in the living room, although it is very Grade, but it's especially hard to watch.
So for the living room TV, what size should be suitable to buy? We all know that when there is a certain distance, when the size of the TV is too large, there is no way to see the screen. You need to turn your head or turn your eyes when you watch. In the process of switching the screen, the eyes need to constantly adjust, and the big screen shows the children. The mind is in a state of excitement for a long time, and it is easy to delay learning and make it easier to be nearsighted. When the size is too small, images on the screen cannot be clearly seen. This can easily cause eye fatigue.
In general, the generally accepted view is that the viewing distance is estimated from 4 to 6 times the screen diagonal. Obviously this does not take into account the different algorithms of different TV sets. This is only suitable for the CRT TV era.
Therefore, before we buy LCD TVs, we must first measure the size of the living room to see how much the living room is suitable for buying LCD TVs. Under normal circumstances, the best viewing distance for LCD TVs is TV screen diagonal x0.0635. Formula to calculate the most suitable size.
Finally, experts suggest that even if the right TV is selected, it is not easy to make your eyes tired, but you should still do eye care. After watching TV for a long time, wash your face with clean water, remove dust, and reduce the impact of radiation; look at 1 hour to rest for at least 5 minutes, otherwise it is still unfavorable for eye health.
With the maturity of TFT technology in the early 1990s, color LCD flat-panel displays developed rapidly. In less than 10 years, TFT-LCD has rapidly grown into a mainstream display, which is inseparable from its advantages. The main features are:
(1) Good use characteristics: low-voltage applications, low driving voltage, and improved safety and reliability of solid use; flat panel, light and thin, saving a lot of raw materials and use space; low power consumption, its power consumption is about CRT display One-tenth of that, reflective TFT-LCD is even only about one-hundredth of CRT, saving a lot of energy; TFT-LCD products also have specifications, models, and sizes in series, with various varieties, convenient and flexible use, maintenance, and update , Easy to upgrade, long service life and many other features. The display range covers the application range of all displays from 1 inch to 40 inches and large projection planes. It is a full-size display terminal; the display quality ranges from the simplest monochrome character graphics to high resolution and high color fidelity. Various specifications and models of video displays with high brightness, high contrast and high response speed; display methods include direct view, projection, see-through, and reflective.
(2) Good environmental protection characteristics: no radiation, no flicker, no harm to the user's health. In particular, the emergence of TFT-LCD e-books will bring mankind into the era of paperless office and paperless printing, triggering a revolution in human learning, dissemination, and recording of civilization.
(3) The application range is wide, and it can be used normally in the temperature range from -20°C to +50°C. The low temperature working temperature of the TFT-LCD after temperature reinforcement can reach minus 80°C. It can be used as a mobile terminal display, a desktop terminal display, and a large-screen projection TV. It is a full-size video display terminal with excellent performance.
(4) The degree of automation of manufacturing technology is high, and the characteristics of large-scale industrial production are good. The TFT-LCD industry technology is mature, and the mass production yield rate has reached more than 90%.
(5) TFT-LCD is easy to integrate and upgrade. It is a perfect combination of large-scale semiconductor integrated circuit technology and light source technology, and has great potential for continued development. At present, there are amorphous, polycrystalline and monocrystalline silicon TFT-LCDs. In the future, there will be TFTs of other materials, including glass substrates and plastic substrates.
