Passive Vs. Active 3D glasses

Friday, February 24, 2012

I try to put your 3D active glasses for the first time, I was quite impressed. It is more expensive and require batteries with one, another is connected to a 3D TV with infared beam to restrict the viewing distance. So when I get more information on LG's passive 3D technology, I immediately went to the store to try it again. I like it so much that it is polarized glasses like I had with the 3D movies theaters. Passive 3D glasses are much lighter than active technology makes it feel more comfortable. LG AG-F210 3D glasses for the two in a box with pouch to store them in, and cleaning cloth. Compare prices on the passive 3D glasses that have been very active 3D glasses.

Pros: lightweight, not requires batteries, cheaper.

Development of 3D TV technology

Wednesday, February 8, 2012

3D TV technology is constantly evolving, this article will present various types of 3D technology from past to present.

1. Anaglyphic 3D technology (Passive)
This technology used "Two-colored glasses" generally red and blue, for filter color to the left and right eye  that want to make 3 dimensional of the image. This Anaglyphic 3-D movie have both as a DVD or movie in HD such as Monster VS Aliens in the Bly-ray or The Final Destination that use Anaglyphic 3D technology.

Pros: Glasses, both paper and plastic are cheap.
Cons: Not realistic 3D images.

Equipment for viewing Anaglyphic 3D.
1. DVD or Blu-ray movie disc format Anaglyphic 3D.
2. Two-color glasses that match the following colors red-blue / blue-yellow / pink-green (the glasses color must be consistent with the movie).
3. Normal TV (LCD TV, Plasma TV, CRT TV), not necessarily 3D TV.

2. Polarized 3D technology (Passive)
The principle of Polarized 3D is displayed even line picture (2,4,6, ... 1080) for the left eye (540 lines) and the odd line picture. (1,3,5, ..., 1079) for the right eye (540 lines at left). The display quickly switches even and odd line to the eyes this call Line by Line medthod. 3D Glasses for Polarized have lenses for the left eye get only even line picture and lenses for the right eye to get only odd line picture, that take quickly swap left and right and make three-dimensional image. Polarized 3D TV for release in 2011, including LG LED LW6500, Phillips PFL7606, TCL V6300 and "Cinema 3D TV" from LG. The Imax 3D cinema use Polarized 3D technology as well.

Pros: Most fly out 3D image dimensional, lightweight glasses does not require batteries, pictures not blinking.
Cons: Separate line picture left and right for half that decreases the contrast of the image.

Equipment for viewing Polarized 3D.
1. Polarized 3D TV.
2. Polarized 3D Glasses.
3. Polarized 3D Content (Line by Line 3D Content).

3. Active 3D technology (Frame Sequential 3D)
Principles of Active 3D is to send full-frame fast switch to the left and right eye (as at 60 frames per second). It makes 3D images are overlapped between the left and right, 3D Active Shutter Glasses that alternately open and close quickly left and right. Active 3D be used in TV such as Samsung, Sony, Panasonic, Toshiba like Samsung 3D LED TV (D8000, D7000), LG Plasma TV PZ950, Sony HX925, NX720 Panasonic VT30 and released in 2011.

Pros: The picture is sharp more than Polarized 3D.
Cons: Glasses need batteries, need to connect (sync) optical Infrared signals to the TV all the time, making the limited viewing distance, flashing of glasses.

Equipment for viewing Active 3D. 
1. Active 3D TV
2. 3D Active Shutter Glasses
3. Blu-ray player with 3D models that can Output HDMI V1.4
4. 3D Content.

Synopsis: This article was made ​​you to know more about the type of 3D Technology. And now, for the most 3D TV  were implement Active 3D (Frame Sequential).

Principle of 3 Dimension Imaging

Tuesday, February 7, 2012

Today, 3D TV was very popular. You want to know that the 3D imaging technology for TV and movies are a few types. Let's start with the first 3D visualization models.

What is 3D image?
3D or 3 Dimension picture is a picture that can see "shallow, deep, thick, thin" clear more than 2D picture.  Comparison with 2D images the 3D will make realistic and makes you feel into to be realistic place, that is why the TV production attention turned to the production of 3D TV.

The 3-D visualization.
3D images were created by physical principles of the two sides of the man's eyes, When see to the objects there are in different positions (because the left eye and right eye were separated about 3 to 5 cm.) and when the two eyes result are combined, we will see 3-D image. With this simple principle when the picture was taken from the left and the right to gather together. We would like to see the 3D image.

This is principle of 3D imaging in the next article I will discuss the type of 3D that has evolved from past to present. See you...

LCD TV VS Plasma TV What Different?

Monday, February 6, 2012

For those who are choosing to buy new TV, here is popular question that many people have in mind between LCD TV and Plasma TV that is different? And is better? Will know the answer you need to understand the principle, advantages and disadvantages of both two types of TV before all.

LCD (Liquid Crystal Display) is generated from the light source called the "Backlight", which is light lamp CCFL and LED such a light source to a crystalline solid, semi-liquid like jelly called "Liquid Crystal" and it will be change cause deformation the light coming from the Backlight to Color Filter to pass through the primary  three colors (RGB) and mixed into a different light.

Each pixel of the LCD TV can not provide their own light. It necessary to rely on the Backlight light source to a Liquid Crystal and determines the direction in determining the color that you see by working together with Color Filter. LCD TV will have a variety of sizes ranging from 15 inches to 108 inches.

Advantages of LCD TV.

  • The bright light over.
  • Suitable for a computer monitor and a mobile video monitor with a resolution greater than.
  • Suitable for use in high brightness room. The living room is light controlled or you can buy to be installed in a store or restaurant, LCD TV is more appropriate.
  • Burn-In a fire or holding it on display will likely not happen.
  • Less power consumption and less heat.
  • Can use for small LCD screen display, such as mobile phones.

Disadvantages of LCD TV.
  • Backlight leakage is also seen in the dark, even when the door is closed for Liquid Crystal Display. But it also has a light through it anyway. Black is not black as they should.
  • Some of the speed of the animation will not flow around.
  • With its bright and vivid colors that go well. (The complete set power mode) can be a pain in the eye.

Plasma TV is a monitor at each pixel can make the light on its own by stimulating the release voltage. Each pixel of the Plasma TV include Neon and Xenon gas contained, it will be a material impact on the UV and  when it go to phospor, a phosphor coating on the screen and make the light colors.Which the gas is indeed more sensitive than crystals.

Advantages of Plasma TV.
  • Can animation better flow than by seed pixel is light itself, For action movies or sports with them.
  • Be black to dark and deep, with more than dimensions. It not have Backlight  to worry about leaks.
  • The contrast of the image above to see a better.
  • Wider View better than LCD TV for the side fade.
  • The colors are more natural not over color.
  • Less eye pain for levels of brightness and color.

Disadvantages of Plasma TV.
  • Burn-In when the opportunity arises, if still open for a long time.
  • Not suitable for use in the control room where the light is not as high brightness light or outdoors.
  • The mirror reflected the shadows.
  • More power and heat on the screen.

I think that the LCD TV and Plasma TV has equal good and bad points. For your information, you should find Reviews, Article, and to try to watch it by your own and choose TV for your room and make the most of your Life-Style.
