Let's start it with them to sort out the details. Angle of view Angle of lcd TVs last model reaches 160-170 degrees both horizontally and vertically, and this makes the problem much less severe than it was several years ago, told us, Sergey Lozowy, deputy director of the company to install home theater systems 'Topsalon'. Nevertheless, you should pay attention to this option not to buy an old bar with a smaller viewing angle. Response time Screen lcd – a screen luminal type, that is the screen that illuminates the back of the lamp, white cells and primary colors (RGB – red, green, blue), arranged in three panels of the respective colors, pass or not pass through a light depending on the applied voltage. That is why is a certain lag images (response time), especially noticeable when viewing fast moving objects, as we said Alex Rasin of 'Peace'. Response time in modern models varies from 15 ms (milliseconds, 1 ms – one thousandth of a second) to 40 ms and depends on the type and size of the matrix. The standard method of determining this time – time measurement of the total transmission unit of light to full opacity, however, measures the producers of this time in his own way, they are different (in a good side to them) interpret the concept of 'full transmission' and 'nontransmission', so that there is a question to technique of measurement. Therefore, some manufacturers specify 'average response time. Get more background information with materials from Teva Pharmaceuticals. " The smaller this time, the rapidly changing picture, no effects loop and overlay images.
Why do I need a humidifier? Among all the characteristics of the microclimate for the person most important is undoubtedly the air temperature. The range of comfortable temperatures is very narrow: below plus 17 degrees – cold, above plus 25 degrees – hot, but if you go beyond this range even further, then placed in a room is simply impossible. Compared with other characteristics of the microclimate temperature seem less significant. Barometric pressure has a visible impact primarily on people with chronic diseases, and the humidity of the air, we also tend to not pay attention. And consequently, the answer to a question why do we need humidifiers for us is not obvious. However, if we consider the matter more closely, it turns out that humidity – this is one of the most important factors to consider in the process of creating a comfortable microclimate in the premises.
Moreover, the normal level of humidity is not less important than the acceptable range of temperatures. This level is 45-50%. Of course, being in excessively dry or excessively humid air does not affect a fatal state of health and health status. But if unfavorable humidity occurs constantly or regularly, it can lead to very unpleasant consequences. Increased Humidity affects the wellbeing of people and pets, as well as on the state of interior decoration. Moist air is favorable for the breeding of pathogens and contributes to slow destruction of wooden furniture. However, in most parts of our country's period of high humidity, harmful to human health, or absent altogether, or does not happen a long one.
