Is the TV in your home LCD or plasma? What are their advantages and disadvantages?
At present, there are still quite a lot of choices for plasma TVs in China. For example, Changhong, Panasonic, Samsung, LG, Hisense, and ViewSonic are all producing plasma TVs. However, compared to selling LCD TVs, almost all brands have LCD TVs.
The so-called LCD TV, also known as LCD TV, is the principle of using liquid crystal to emit light under the action of voltage. There are three kinds of liquid crystals that make up the screen: red, green, and blue. They are called three primary colors. They are arranged in a certain order. By stimulating these liquid crystals by voltage, they can display different colors. The ratios of different proportions can be varied. color. Therefore, LCD TVs that are accurate to "point" are one level higher than ordinary TVs that are "progressive".
Plasma TV PDP (P la sm a D isp lay Pan el) is a mixture of two thin glass plates filled with a gas, a voltage is applied to generate an ionic gas, and then the plasma gas is discharged to react with the phosphor in the substrate. , producing a color image. Plasma color TV, also known as "wall-mounted TV", is not affected by magnetic and magnetic fields. It has the advantages of slim body, light weight, large screen, bright colors, clear picture, high brightness, low distortion and space saving.
How far is it to watch a medium-sized and large-size TV at home?Regarding the size of the flat-panel TV, many netizens will not pay attention, but the author has to remind everyone that the primary factor in choosing a flat-panel TV is not the price, not the brand, not the screen resolution, brightness, etc. The question is how big a flat-panel TV is in your living room. The data map shown below is for your reference only, and the specific situation is judged by the consumer's field measurement.
If the screen is too small, the picture will be unclear and the font will not be obvious. If the screen is too large, the pressure will be too strong, and the eyesight will be too much. If you buy a TV, you have to watch it, but if you are affected by watching TV, it will be worth the loss. The following table is the reference data for different viewing distances corresponding to the appropriate size screen. I don't know if any netizens have taken out the ruler and measured the distance in the living room before purchasing the TV.
How to extend the life of the TV?
Prevent premature aging of the picture tube. The measure is that the brightness should not be too bright when watching, do not switch the TV frequently, try to watch TV when the power is stable. Generally, the effective service life of the picture tube is more than 5000-10000 hours. If the average daily use time is 3-5 hours, the life of the picture tube is generally 5-10 years or even longer.
How far is watching TV without radiation distance?
At present, the radiation of TV sets almost exceeds the safe range. When we watch TV sets, how far can we isolate them from radiation? Through testing, we found that once viewed away from the TV, the radiation value will be greatly reduced. When the distance is more than 0.3- At 0.5 meters, the radiation tends to zero, so when we watch the TV at home, as long as it is not too close to the TV, it will not be harmed by the radiation from the TV.
Do you pay attention to these details when you deliver the goods to your door?Many consumers may not carefully check the packaging of the TV when the color TV is delivered to the door. Then, after you open the TV case and don't check it carefully, the consumer who suffers at the end is still the consumer. So, after paying the door to the door, what should you pay attention to? Please come and find out with the author.
First, many flat-panel TVs are not sealed at one time. Therefore, when delivering the goods, be sure to check the appearance and parts of the TV set, especially if the screen is fragmented. problem.
Second, pay attention to check the old and new packaging. In general, the new machine outer packaging cardboard boxes are relatively new, and the internal components are also placed very standard. It is easy to leave all kinds of marks on the outer packaging of the machine that has been dismantled or reworked, and the things placed inside are relatively messy.
Third, pay attention to the outer box of the TV set for 15 days. Because if there is a quality problem within 15 days, it can be returned. If you throw the outer box, you will have to pay extra for the return, which is not worthwhile.
How to maintain the remote control?
Please replace it when the battery fails, to avoid battery leakage and corrosion of the circuit board; do not let water or other liquids soak the remote control; please do not let the child play the remote control to avoid breaking the remote control; do not use solvents or strong chemicals If the surface of the remote control is rubbed with a light emblem, use a clean soft cloth or cotton gauze to gently remove the dust. If the surface is dirty, use a clean soft cloth or a neutral detergent on the cotton yarn. It is enough to dry naturally after removing the dirt.
