    In recent years, as a result of the LCD market expanding and hot, many function of the LCD panel in constant progress, also be given seamless splicing, hd resolution, radiation protection, etc. About radiation protection that consumers often do not judge, German authority computer magazine "Macwelt" according to a recent survey shows that although the LCD display radiation much smaller than the ordinary, but because of its high brightness, instead more easy for us to make our eyes become tired and may even lead to headaches and other symptoms.       In the survey, the researchers tested 10 different brand 19-inch LCD display, both desktops, also have a laptop computer. They found that all the tested liquid crystal display there is high "brightness" problem. The researchers point out that when the brightness of the display to every square metre 100 CD (that is, the unit of luminous intensity "as" Della), will have certain effects on the eyes. And the LCD screen, they test the luminous intensity is more than every square metre 300 CD, CD. Some more CD 400-400.     Presided over the survey of German computer experts weihai well, "said Dr Not only is the LCD computer, LCD TV, LCD advertising machine and so on also exist the problem. The LCD screen in order to increase the resolution, in addition to the tube by the light of the screen behind improve brightness, also widely used specially "technology" make screen surface looks like a piece of glass, it's very simple sense, but also improved the color contrast and saturation of the screen. However, it will also be like glass reflect light.                  Especially when the light to the screen, can increase the light reflection. Use this display of consumers, it is easy to light "sting", and produce the symptoms of eyes tired, slowly can also cause health problems of decreased vision and headache.       Is it because it will no longer buy LCD screen? Actually every product in bring convenient at the same time accompanied by subtle faults, LCD screens have been integrated into our life, the function is worth to look forward to, is a power greater than before.        So, how do you prevent LCD damage to the eyes?     1. To prevent the light reflection, our eyes and the distance from the screen with 60 centimeters advisable.     2. General liquid crystal display brightness adjustment function design are, when use, can turn down the brightness as far as possible.     3. Might as well on the LCD screen with a light reflective LCD screen protection film, which not only can prevent the damage to the LCD screen, can also prevent the light reflection and vertigo.     4. Might as well choose a new on the market with low reflective liquid crystal display technology of LCD display, emperor ai emperor LCD screen, for example, the design greatly reduces the light damage to the eyes.     5. If on the display screen for a long time, can buy radiation protection glasses       DDW think LCD relative to the last century the lion's share of the television, resolution and radiation rate is relatively better, function more and more, the application scope is more and more widely. Now don't have any all appliances can be totally prevent radiation, a good display only can minimize display radiation, at the very least, yet it is not a zero radiation of electronic products, we can do is use some way to prevent radiation.    

    We all know that the dust has a harm to human body, but you never know dust as well as for the LCD splicing screen so, emperor ai emperor today with dust to everyone how big to the harm of splicing screen, like mist have serious harm to human body, similar to the haze of dust is a sworn enemy of electronic products, LCD splicing as electronic products with extremely high content of science and technology, dust also produced great impact on it. Liquid crystal splicing screen movement using a large number of optical element, is just the dust harm to optical element is the largest. The focus of multimedia is parsing the dirt on the LCD splicing screen for you direct harm is divided into four points.     1. The contrast down     Contrast ratio is defined as the brightness of the display unit can output the maximum values divided by the brightness values of the dark, when the dark scene the dust on the optical components can reflect a stray light, projection will not out of light from the lens, increase the brightness of the dark. The same in the light part of the light will be dust, reduce light bounces back and through capacity, and reduce the brightness of the light value, to get a contrast down naturally.       2. The color wheel speed reduced     LCD splicing screen color wheel is one of the important parts, color processing with high speed motor, speed of about 7200 rotations per minute (RPM). If a lot of dust around the color wheel, can affect the color wheel rotation, which reduces the color wheel speed or unstable, fault occurs.       3. The screen brightness     The brightness of the LCD splicing screen was conducted through reflection lens and lens output brightness, if the dust accumulation in optical component surface, reflectance and transmittance is diminishing over time, causing the deterioration of brightness.       4. The image blur     When dust inside the splicing screen on the optical components of accumulated to a certain extent, could change the light path, cause the light focus when unable to gather in the same focus, so makes the display on the screen image blurring. Everyone thought the dust at ordinary times is only affect the surface of the LCD screen, but don't know have so much influence on the LCD panel function, in daily life, it is important to note that dust, to prolong the service life of the product.       DDW sincere hope every customer in the selection of emperor ai emperor LCD splicing screen at the same time, more to get high quality satisfactory service, to make all customers of the company's long-term cooperation partners, "this is the emperor of emperor ai a promise made to each customer, also is our pursuit of the goal and ability.
