Now you can see your friend physically present in front of you, whenever you wish

Yes, just dial phone to your boy friend/girlfriend and he/she  will come in-front of you , this is possible now by using 3D technology without glasses in mobile phone. This technology already started by few mobile companies like HTC, LG…

LG Optimus 3D – the World’s First Full 3D Smartphone

HTC Launches HTC EVO 3D Glasses-Free 3D smartphone,

      

The new mobiles comes with Dual camera which record 3D video. One camera is processed with a red overlay while the other is with blue. The images are layered on top of each other, creating a double-vision effect, and then the composite images will be sending to other receiver mobile.

The 3D effect is delivered via lenticular lenses which create nine different perspectives or views of each single 3D frame - a sheet of convex lenses on top of the display controls how light emits from it and delivers the images at an angle to each eye - thus creating the difference in images our brain needs to 'see' in 3D. Lenticular lenses have another benefit in that they make it possible to see multiple different images from multiple angles, in effect allowing more than one person to view at the same time.

Though several methods already exist for glasses-free 3D TV, parallax barrier technology and lenticular technology are the most common so far. With parallax barrier technology, the “filter” function of 3D glasses is replaced by a layer of material in front of the screen itself. Through a series of slits, the layer allows each eye to see a different set of pixels, thus creating the 3D effect. The parallax barrier only works if the viewer remains in the same spot, making it suitable for small display units but not so great for TVs. In addition, with parallax, the screen’s brightness suffers.

Lenticular technology is actually based on an old printing technique in which an image changed slightly depending on the angle it was viewed from (a simple example of this technique is on children’s rulers that are decorated with images that seem to move when the ruler is rotated back and forth). Lenticular technology works by arranging small lenses on the display and refracting the left and right images to send separate images to each side. On the plus side, lenticular displays have less reduction in brightness and a slightly wider range of viewing angles. Unfortunately, they are also very difficult to produce, and hence very expensive.

the LG Optimus 3D is the 3D phone that can take 3D photos with 3.2 megapixel qualities. In comparison, the 3D resolution for HTC’s EVO 3D and Sharp’s Aquos SH-12C is only 2 megapixels. Of the devices being compared, the only one that offers better quality images and videos than the LG Optimus 3D is the 3D digital camera by FujiFilm which offers 10 megapixel resolutions both in 2D and 3D.

The display size that influences the degree of 3D effects is a significant factor since consumers frequently enjoy their photo and video content directly on their phone screen. The LG Optimus 3D’s 4.3-inch LCD screen has a resolution of 480 x 800 pixels to offer great 3D effects.

HTC EVO 3D Glasses-Free 3D smartphone available in the Indian market offering a superior 3D viewing experience without glasses. Other specs include a 4.3? 3D display with pixel dimensions of 540×960, a gigabyte of RAM, secondary 1.4 MP camera, microSD card slot, Wi-Fi, Bluetooth 3.0, GPS, microUSB with MHL (Mobile High-definition Link) support, and a 1730 mAh battery.

These both mobile cost in India is around Rs 35000/- .
