3D TV Comparison : LED Vs. LCD Vs. Plasma

I do not normally write about consumer electronics on GoRumors. But a recent article on HDTVMagazine made for interesting reading. In the article, the author has studied how the viewing angle affects the 3D viewing experience on LCD and Plasma television screens from Samsung and Panasonic.

Here are some notes from the study

Samsung 55″ LED TV
The 3D viewing is perfect when your head is held straight and at the ideal angle to the screen. However, viewers may experience slight ghosting as the viewing angle changes. When the viewing angle is tilted by as much as 80 degrees, the LCD screen is cancelled out by the polarizing angle of 3D glasses and the image may be completely dark.

Panasonic 50″ Plasma Screen
Unlike the LCD screen of Samsung, the Plasma screen on a Panasonic TV appeared to be free from any appreciable cross-talk and ghosting even when when the viewing angle was tilted by as much as 90 degrees. The brightness dropped by a little, but casual viewers may not even notice.

The performance deteriorates drastically with viewing angle on an LCD TV. This is because the LCD TV only makes use of one polarizer per glass lens thus causing much more crosstalk. On the contrary, the Plasma screens from Panasonic made use of dual polarizers that helped in minimizing ghost images.

The study concludes by saying that while Plasma shows marginal ghosting, the performance is significantly better than LCD or LED. You may expect even more improved performance when OLED TVs make it to the market. But that’s sometime away and so if you are going for a 3D TV now, maybe choose a Plasma.

LCD Vs. AMOLED Vs. Super AMOLED Sunlight Test

Sometimes display technologies can be quite overwhelming for regular users who do not actually care about whether the display is LCD, AMOLED or Super AMOLED. However, each of these different technologies do perform differently and it makes sense to offer a look into their performance before deciding upon the phone of your choice.

Folks at TechBlog give us an excellent demo of how these three display technologies fare under bright sunlight. As you can watch from this long video below, there is little to choose from since none of the three screens are explicitly better. Nevertheless, the LCD on Nokia Xperia X10 appears to be marginally better than the Super AMOLED screen on Samsung Galaxy S which is in turn better than the AMOLED screen on HTC Desire.

What are your views? Watch the video and tell in the comments.

Sharp 3D LCD Screen For Mobile Handsets

Motorola is not the only company working on developing 3D display technology for mobile phones. Japanese electronics manufacturer Sharp has revealed that the company is working on a special LCD screen that can bring 3D display to the mobile phone handsets. With this display, users may be able to view 3D graphics on their mobile phones without the need to wear special 3D glasses.

However, the technology is not at its best as yet. According to a report on ComputerWorld, the 3D rendering will happen only when the screen is viewed at an appropriate angle and distance. The report notes,

“To get the 3D illusion viewers must hold the screen about 30 centimeters in front of them — about the same distance at which a cell phone or digital camera is typically held. If they get the angle right, they will see an image that appears to have depth; if they get it wrong they will see a blurred image that’s difficult to decipher.”

However, users may be offered an easy way to switch between 3D and 2D display which should make it much more useful.
