The Advantages and Disadvantages of the Lcd Video projection Television
Advantages Of Lcd Video Projection
1. What makes the Lcd projector assembly very practical is that it is compact, since the Lcd chip is very small.

One Lcd chip is hundreds of times smaller than the three corner tubes needed in Crt-based rear-projection televisions. This means that Lcd-based rear-projection televisions can be made a lot thinner and lighter than customary Crt-based rear-projection sets. Although you can’t hang it on the wall like you can with an Lcd flat panel or Plasma Television, you can still save a lot of floor space, and spend less money than you would buying that stylish Lcd flat panel or Plasma set. In addition, since these are corner sets, you can get one in larger screen sizes than you can with whether Lcd or Plasma flat panel types.
2. Other advantages of rear-projection Lcd technology are its high dissimilarity and glow capability, as well as lower power consumption.
Limitations Of Lcd Video corner
1. A Lcd corner television can often times exhibit what is called “the screen door effect”. The screen is made up of indivudual pixels, therefore ey can be seen on a large screen. This gives it the appearance of viewing the image through a screen door.
2.The construction of Lcd Rptv may seem simple, any way they are still more complex and therefore normally much more costly than their Crt counterparts.
3. Since an Lcd chip is made up of a panel of private pixels, if one pixel burns out it displays an annoying black or white dot on the projected image. private pixels cannot be repaired, if one or more pixels burn out, the entire chip has to be replaced.
4. Since Lcd chips have a finite whole of pixels, signal inputs that have higher resolutions must be scaled to fit the pixel field count of the singular Lcd chip. For example, a typical Hdtv input format of 1080i needs a native display of 1920×1080 pixels for a one-to-one display of the Hdtv image. However, if your Lcd chip only has a pixel field of 1024×768, the customary Hdtv signal must be scaled to fit the 1024×768 pixel count on the Lcd chip (in addition the image will also have to be letterboxed to reproduce the accurate widescreen aspect ratio). This is where Crt-based rear-projection sets can excel over an Lcd rear-projection set. Since Crts are not little by a fixed pixel field, they are more flexible at displaying assorted resolutions, due to being able to variably scan the image onto the corner tube surface.
