Nowadays, with the rise of more portable mobile devices, the use rating of TV is less. In the fast-paced modern life, many young people hardly turn on the TV. Some young people turn on the TV, but their attention is on the mobile phone. More renters don't have TV at all. The mainstream group of TV user has become consumers over 40 years old. But in the era of nearly universal use of smart phones, mobile phones are more suitable for people to spend their fragmented time. How to watch videos comfortably with various postures is the core of entertainment life. The projector saw the opportunity and began to compete with the TV. The projector said, "choose me. I will follow you in any position you want. It's OK to move the picture to the sky." the TV said, "I really can't do this."
TV vs Projector
Today's TV is basically a liquid crystal screen. Each pixel corresponds to a fixed liquid crystal molecule. The voltage adjusts the orientation of the liquid crystal molecule, and different pictures are displayed. Most manufacturers will choose PWM dimming due to cost reasons, that is, to make LED light repeatedly dark, eyes cause frequent flicker impact, which will make people tired of eyes.
The light-emitting elements of the projector gather all the light beams to form a uniform and stable projection picture after the reflection of the mirror for many times, avoiding the damage to the eyes caused by the flicker of the PWM dimming picture. Some LCD screens rely on the light tube behind the screen to brighten, and also use the "polishing technology" for the display screen. The light reflected from the mirror surface is easy to make the user's eyes tired, causing vision loss and headache after a long time.
The principle of the projector is to first irradiate the light on the image display element. When the generated image is projected to the screen or wall through the lens, the wall and screen will not have specular reflection, which is relatively less harmful to the eyes. But in terms of screen resolution, the projector is really inferior to the TV. The TV is basically 4K, and the color is richer, fuller, more delicate and lifelike.
Buy projector or TV
Once faced with making a choice, it gets tangled. Projectors and TVs have their own advantages. However, when choosing them, we can consider the size of the home space, the users and the use scenarios.
Home space size
Whether you use a projector or a TV, you need to keep enough viewing distance. According to the "30 degree theory" algorithm proposed by the International Association of film and television engineers and a series of mathematical formulas, the distance between the human eye and the screen is estimated, which is at least 1.6 times the diagonal length of the screen. The projector only needs a curtain or a wall to win in space saving. From the reality, what kind of space will match how big the screen is.
It's better for old people and children to watch TV
There is no doubt that the brightness and definition of TV is better than that of projector. The vision of the elderly is decreased, which may be accompanied by cataract, glaucoma and other diseases. The eyes of children are not mature. Because the screen and wall do not shine, the image effect of the projector will be limited, so the darker the surrounding environment light is, the clearer the image is projected, but the darker the light is, the more likely it is to make the eyes tired, induce the onset of eye diseases of the elderly, and easily cause The child is nearsighted.
Projector: More flexible
Projectors can be used in a wider range of scenarios. In the company meeting to make a report, display PPT, school class to show teaching content, the effect of the projector is much better than the effect of the computer screen, convenient for a large group of people to watch at the same time. If you want to pursue immersive audio-visual experience when playing games and play games happily on the large screen, then the projector is just right for you. And for renters, projectors are really much more convenient than televisions. They don't need to occupy too much space and fixed location to solve the problem of changing houses and moving houses perfectly. If you want to buy projector, there are 6 keys when you choose a home projector.
In a word, if you don't have too high requirements for experience, just want to meet the needs of daily pursuit of drama and entertainment, a hundred or two hundred projectors will do. If you are the pursuer of refined life and want to create a cinema atmosphere, you must choose a high-quality projector with high reduction degree, and spend more time and energy selecting blackout curtains and anti light curtains. Of course, you can also choose the high-end 4K / 8K TV.
