Projector or TV? Here's a summary of the pros and cons you want

With the rapid development of today's society, more and more high-tech products emerge in endlessly. The power of many electronic products surprised us all. In the electronic industry, the most representative is television. The emergence of projector has improved our expectation for the arrival of the era of science and technology. Today we will analyze the advantages and disadvantages of projectors and TV sets.

There are many advantages, such as space saving. The reason why consumers choose a projector is that the projector can project a larger picture in a smaller space. In order to obtain the largest projection area, besides using wide-angle lens, the most important method is to increase the projection distance as much as possible. The projection screen has low requirements, and the projection mode relies on the projection screen to reflect light. Therefore, unless the image requirements are strict, as long as the general projection screen can meet the requirements, and even some people use white walls. Therefore, the requirements of projection screen are very low, and the flexibility and environmental adaptability are stronger. In other words, the projection mode can be selected without hesitation in most occasions.

The disadvantages also affect the beauty of the environment. Because the projector is on the same side with the audience, the appearance, interface and wiring of the projector are exposed. Even if the projector with wireless network connection can only reduce the part of wiring related to network connection, most of the basic wiring can not be saved. Whether it's a home, classroom, office or demonstration hall, a variety of messy wiring will ruin the scene. Therefore, the overhead projector is generally used to solve this problem. Although the noise of the projector is certain under the normal working environment, the distance between the audience and the projector on the same side will obviously make the noise problem become a factor that has to be considered.

The disadvantage of TV is that the reaction speed of traditional display is very good due to its technical advantages. TFT liquid crystal display is not so optimistic due to its display characteristics (low temperature can not work normally, and there is reaction time). LCD response time is relatively long, so the performance of dynamic image is not ideal. Display quality: the display screen of traditional display adopts phosphor, which is displayed by electron beam striking phosphor, so the brightness of display is brighter than that of liquid crystal transparent display (with fluorescent lamp as light source).

The advantages of green environmental protection, non radiation LCD has no radiation at all, and only a small amount of electromagnetic wave from the driving circuit, as long as the shell is strictly sealed, the leakage of electromagnetic wave can be eliminated. So LCD is called cold display or environmental protection display. LCD TV does not exist the phenomenon of screen flicker, which is not easy to cause visual fatigue. Low power consumption and long service life. According to the industry standard, the power consumption of LCD tube can be reduced to 32.5 inches per day, which can replace the power consumption of TV set by the industry standard. The service life of LCD TV is generally 50000 hours, which is much longer than that of ordinary TV.

It can be seen from the above that the advantages of projector and television are many, but the disadvantages are also relative. So both of them have shortcomings, and all things are not perfect. Everyone's appreciation is different, so you can choose a product you like according to your own habits and hobbies.
