Although the reflections of our lives are clearly visible on television, television and real life are completely different. In the sky, sky-kissed buildings also go within 12-inches, but still we like to enjoy it. But if television pictures can be seen on the wall by making a big size TV projectorThis works exactly; It helps to enhance the music from Traditional Television by 5-7x or more, so that it is possible to make videos or movies more funky. It is used extensively in business meetings, schools, college lectures, not just to enjoy movies at home. The old CRT (cathode-ray tube) TVs of today's day or today's LCD TVs provide quality quality picture quality, but there is a limit of their size.If hundreds of people living in a huge room are trying to show the same picture at the same time, then the projector has no alternative. Diamonds are possible to connect a DVD player, computer, or any video source and immediately make the image giant But how does it work? What are the technologies behind it? Let's know the details ...
Projection

In short, many of the favorite games are trying to catch the shadow below, and I myself have not been able to do it. At the time of my reading on the shadow wall, I thought of a strange thought, and that was the basic thing of projecting. That is, since we have no knowledge, we are seeing the projection. If you have a light source and if you put an object in front of it, then an image of that object will go over the wall.Today, we have been preparing different types of projects from the ancient period, not by the use of projectors today. Put the shadow behind the object in front of the light, and we can also create animations by moving the object. This is the main motto of Prosecution.
An example of how radical TVs work to understand how Projection TV works. The electron beam is thrown from a cathode ray tube on a TV screen (Phosphor-Coated Screen) on a normal TV. Every time a single electron comes in contact with the screen, the single point is called pixel,Which is bright. Color CRT Television has three electron beams and has three distinct green, red, and blue colors; When you look at these colors from a distance, you feel like a picture.
Although CRT TV's color presentation and picture quality are very good, its biggest problem is that it is possible to make the CRT screen up to a maximum of 40 inches wide. And for this reason the projector needs to be made; Without using direct-view technology such as TVs, small pictures are made and the film is enlarged with large light beams.
Projection type

The projection is mainly seen in two main types; Another "back projection" is another "back-projection". If the light is behind you and the screen is in front of you, thus creating the image means Front Projection. For such a project the projector and screen need is needed and the projector position in front of the screen is necessary. You can get this type of projection setup especially in movie theater, where the project unit is completely separate from the screen.The projection unit is attached to a table or roof, with special clothes or specially painted walls as screens. Prior to its popularity in TV, Front Projection was the most popular.
Moreover, it is possible to make a projection using another different method. The projection of the projection or rayya works like a radical TV. There is no light on the screen from the front and behind the screen light creates images, which can be enjoyed by the visitors who are in front of the screen. Here the projector is attached to the TV. Where the picture is taken after making the electronic mechanism behind the screen. That is, the example of television itself back-projection.
The type of projector

Projection TV basically completes the work by using two different technologies together; Here the image is created by utilizing television technology and the image is thrown onto the screen by using projector technology. The projector has a cathode ray tube to create an image similar to television, but the CRT size is smaller than the TV. To create an image like TV, the electron was thrown over the screen onto the blazed screen.You have noticed that there has been a change in TV technology for several decades. The first was a huge ugly CRT TV, then replaced the flat-styling LCD TV, and now the latest TV technology is Plasma TV, Oleed TV. In the same way, projector technology has changed over time, and we have been present in different types of projection televisions.As all the tech technologies work in different ways, different projector technologies work in different ways. Let's know the types below ...
CRT projector

This is the first technology projector, which works like a radical CRT TV, but it can be compared to a huge powerful TV. There is a light beam like TV, but it is too big in size. Three different color beams thrown light to create images on green, red, and blue screens. All the lights point together and create a full color image on the screen. But such projectors are huge in size, which is not portable at all,But from other projectors it can provide more color and picture quality. But it costs too much electricity. However, although it is the oldest technology projection system, but still it is capable of working with current HD TVs, Blu-ray players, DVD players.
Lcd projector
The way in which the LCD TV has ended the day after the arrival of the CRT TV, the projector is very similar to the case. The LCD screen is very cheap, slim, low power, and lots of bright. The electrical current could change the liquid crystal sip. And this feature turns them into a light violet - various quantities of light supply lights through crystals at different levels.Inside the LCD projector, a small LCD screen is fitted, in which the image is made. And a large magnificent lens is fitted in front of the screen, which creates large size images on the screen while increasing the size of the small screen. The LCD projector is portable enough, so it is very useful to carry and use at home. But color quality is a low quality compared to CRT projectors, but it is not a big thing for home users.
DLP projector

This DLP projector consists of a digital micromirrier or a microchip called the DMD; After that, the latest Lcd projector seems to be a primitive tech after the evolution. It has a rectangular chip partition, which contains two million microscopic mirrors. As the computer processor is made by the chip transistor, the same is made by the DMD mirror (mirror). A bright light illuminates this DMD chip and continuously shakes an electronic circuit mirror.We know that when you move a mirror in front of the light, the mirror lights up and the light continues to reflect. Just as we played with mirrors reflecting the sun's light in small spaces. Two million miniature mirrors in the chips work as pixels and through it the image on the screen is created by conducting different color light. If no light is operated through a mirror, then it is dark, and used as a black pixel.2 million pixels are able to create high resolution images. It can also project the screen from DVD, Blu-ray player, computer, or any video source.
is is very helpful post. thanks for this post
