FUTURE OF TELIVISION! CES 2009 TELIVISION ROUND UP:LED TV-LASER TV-GESTURE CONTROLLED TV

Television as we normally think as a mere box controlled by a remote control is going to take a serious makeover.We take a look at the various future trends in Television technology.

They say bigger is better, as can be seen in the case of worlds largest tv. But more practically, the traditional 4:3 screen tvs are certainlty going to be knocked out by more rectangular 16:9 widescreen tv.The concept of high-definition is also undergoing huge makeovers , so much so that a phenomenal resolution of 7680 pixels by 4320 is now being brought into mainstream tvs.
ou think, the refresh rat of 60 fps is the max- nope! brace yourself for 120 fps- says Bruce Walker from Toshiba.

Laser TV

Lasers are all set to become an ideal replacement for the UHP lamps which are currently in use in projection display devices such as rear projection TV and front projectors. Current televisions are capable of displaying only 40% of the color gamut that humans can potentially perceive. In contrast, proponents of Laser TV technology claim that the standard will be able to reproduce about 80% of the colors visible to the human eye.

A Laser TV requires lasers in three distinct wavelengths seem to: Red, Green and Blue.
Laser tvs seem to be half the weight and cost of Plasma or LCD displays,have a very wide colour gamut. Twice the color of today's HDTVs, have an extra lifespan and require around 25% of the power required by Plasma or LCD displays.Laser Tv technology was introduced to the world by Australian Larry Marshall. Now electronic giants like Toshiba have released their laser tvs in CES 2009.

LED TV

LED tvs are nothing but LCD tvs with LED backlight.But to take that one step further, instead of florescent lights behind the screen there is a full grid of LEDs and now if one corner of the screen is bright the LEDs burn bright.

If the bottom of the screen is dark, the LEDs can turn off so individual zones can be controlled based on the incoming signal.

Organic LEDs(OLED) are another section of the LED tv bandwagon.OLED technology consists of extremely thin layers of organic material applied on a substrate such as glass. When stimulated by an electrical charge, these materials emit light.Active-matrix (AM) OLED displays have electronic circuitry built in, so each pixel is driven independently by a corresponding circuit.Traditional LCD tvs have their future in doubts thanks to their LED enhanced counterparts since LED tvs have the distinctions of being thinner, lighter,clearer, brighter,wider viewing area,lower power consumption typically operating at 2 to 10 volts.The main players in this field include Samsung,Sony andLG.

Gestutre Controlled TV

The days of remote controls is going to be over soon as new gesture controlled TVs are going to rock you.No more there be the need to keep pressing at those buttons on your remote, no more waorrying about having to change the remote batteries- simply show gestures with your hands and wella!
Hitachi were one of the firsts to show off their Gesture controlled tv at this years CES .Various hand gesture-operated TV demos have shown that a user could rotate an image, move one of the video windows to the side, or zoom in or out of video on the screen, simply by changing hand movements (circling, moving to left or right, or forward/backward). Hitachi for instance, use infrared technology (IR) to see user’s hand motions and respond accordingly, while Panasonic uses a new image sensor unit consisting of a near infrared LED, a special charge-coupled device (CCD) and a field-programmable gate array (FPGA).This sensor unit detects gestures by measuring "time of flight" (the time it takes for the near infrared light to hit an object and its reflected light to return to the CCD image sensor module). Each "time of flight" is measured per pixel. Its cumulative data calculates the distance, capturing the depth information of the gesture at real time..One can wave to the TV to turn it on, while changing channels was performed by waving horizontally to bring up a channel menu, then moving an open or pointing hand in a clockwise circle to advance through the channels or counterclockwise to go down through them. Adjusting volume levels was done in similar fashion.
