Users questions: Why are the new generation of widescreen display? Previous televisions, monitors are all 4:3, close to the square, and now LCD monitors and LCD TVs are widescreen, 16:9, Why? This widescreen TV has a big drawback: when watching TV images will be pulled flat, Deformation, the circle have become oval, and became a stocky guy, What the devil! ============================= My green initiatives: 1. The home energy-saving lamps replace incandescent bulbs, although the moment you point, but you can save a lot of electricity (in fact The traditional incandescent light bulbs will be 90% of electrical energy into heat energy wasted); 2 do not drink hot water in the dispenser when the power off, saving electricity should pay; 3 plastic bags should be charged, with shopping a package, not only saving money to buy plastic bags, but also to reduce the white pollution; 4 power with rechargeable batteries instead of disposable Pool, can not only reduce pollution, the future can also save large sums of money to buy batteries; 5 go to use public transport and bicycles, is the real benefit; 6. Do not try to disposable chopsticks, chopsticks because it is the forest killer; 7 pre-brushing with a beaker containing water, you can turn off the tap when brushing your teeth, To avoid unnecessary waste. As long as we change some habits, you can dedicate yourself to slow global warming, a strength, but also save money, why not? If you support environmental protection, to set the copy of the initiative to more pages on it! Thank you for your support. In addition, I found that many people in the wash Face, the tap when brushing your teeth is always wide open, who was standing next to the wash, brush your teeth, do not touch the bit stream, in this process are probably 80% of the water flow away in vain. China is a water-short countries, why do not we reflect? PS: the world's ten most polluted cities: Beijing, Taiyuan, Milan , Urumqi, Mexico City, Lanzhou, Chongqing, Jinan, Shijiazhuang, Tehran (thanks to Peking University Professor Wu Guosheng to provide the list)
Experts answer: widescreen TV made because our technology is to go along with the foreign, foreign countries began to develop wide-screen 20 years ago In recent years, general screen has been completely eliminated, I Their companies had no choice but to follow up (because the technology is mainly dominated by foreign, non-no to do a follow-up), but foreign widescreen widescreen television signal, a perfect combination of hardware and software, the screen will not be deformed. We played P-screen signal, it will deform (if you play Blu-ray is not genuine change Shaped). As for overseas development was mainly due to wide-screen widescreen closest golden ratio, the best visual effects. Basically this is the movie screen ratio. Widescreen LCD monitor is mainly because at first made of the same diagonal size of the panel cut, wide screen, you can cut a lot more than the S & P, so that the cost of each screen Relatively low. And at the beginning of the wide part of new products, higher selling prices. This cost-price, the profit is much greater than the general screen, so all manufacturers have followed suit, wide-screen will form the mainstream. Of course there are made with wide-screen television in which work similar reasons.
