The quality of TV screen is directly related to our viewing enjoyment. Nowadays, more and more LCD TVs have added dynamic contrast and natural light adjustment technology, which not only improves the display effect of the picture, but also effectively improves the tailing phenomenon of dynamic picture. Today, I will introduce you how to choose LCD TV.
Tips for choosing LCD TV
1. Interface. At present, the best interface standard for LCD TV is HDMI. This interface can transmit audio and video signals at the same time. It can not only simplify the connection and reduce the burden of connection, but also provide a huge bandwidth required for digital signal transmission. In the future, this interface will be used in CD players, computers, home theater and other equipment.
2. Bad screen. Bad point, also known as "dead point". The bad spot appears on the display panel. It may be a black dot, or a green or red dot. The bad point problem is one of the biggest problems perplexing LCD TV. The bad points on the LCD panel can't be repaired, only the LCD panel can be replaced, and the LCD panel almost accounts for at least 70% of the cost of the whole LCD TV set.
3. Response time. The so-called "response time" is the response speed of LCD screen to input signal, that is, the reaction time of LCD from dark to bright or from bright to dark. Obviously, the smaller the signal response time, the better. The smaller the response time, the user will not have the feeling of shadow or drag when looking at the moving screen. Moreover, the requirement of LCD TV is higher than that of LCD. The shorter the signal response time is, the better the display effect will be.
LCD TV maintenance skills
1. Daily use. Try to avoid displaying the same picture for a long time. Long time working is easy to cause internal aging or burning out, especially if the same picture is displayed for a long time, it may cause some pixels to overheat and cause internal bad spots. And this damage cannot be repaired. Therefore, when not in use, you should turn off the display or select the screen saver, or turn the display brightness down.
2. Where to put it. Keep the environment dry and away from chemicals. If the environment humidity is very high, the interior of the appliance will condense, which is easy to cause leakage, short circuit, etc. The hair gel and mosquito repellent usually used are high volatile chemicals, which will dissolve this special coating, damage the liquid crystal molecules and even the whole screen, and shorten the life of the TV. Therefore, the contact with water and chemicals should be avoided as far as possible.
3. LCD can not be cleaned frequently. The correct way to clean up is to take a screen cloth with a little glass cleaner and gently wipe the stains off. Pay attention not to let the cleaning agent flow into the interface of screen and screen frame, so as to avoid short circuit. Do not use hard towel to scrub, so as not to scratch the screen. And regular and quantitative scrubbing.
