The trendy LED TV seems to be everywhere these days. Yet, everyday newer technology innovations bring about changes in the LED display TV. The possibilities seem to be limitless, and manufacturers are pushing the boundaries when it comes to their lines of LED TVs.
Probably, the newest technology to hit the LED display TV seems to be flexible screen formats. These screens can supposedly be stretched to fit any contour, and yet retain their transparency. These modern display screens tend to combine durability and brightness of LEDs along with flexibility of carbon-based materials. Researchers are still working on this technology and have built LEDs over thin film layers, which are subsequently dissolved with chemicals. Small plastic tabs are then affixed on both corners to prevent washing away of the LEDs. These inorganic LEDs can be easily stamped onto plastic, glass as well as rubber surfaces.
360 Degree Versions
Most people are used to the flat screen, conventional LED display TV. However, Taiwan-based company Dynscan has developed a new display, which provides a 360 degree view. The amazing feature about this is that image color, quality as well as contrast are exceptionally brilliant with the display screen itself being enormous. The largest screen size of this product is 2.5 meters in height, 5.46 meters in circumference and it can be seen from a distance of even 30 meters with complete clarity! The screens comprise three pieces of identical imagery and each section comprises 120 degrees of the entire screen. The new technology is being seen as a novel medium for advertising campaigns.
OLED or Organic Light Emitting Diode is an LED where the top layer is comprised of organic compounds. These compounds emit light as soon as electric current is passed through it. The layer of organic material is sandwiched between two electrodes one of, which is transparent. Currently, OLEDs are predominantly used in computer monitors, television screens, portable small screen systems like PDAs and mobile phones. Such OLED LED display TV screens do not use backlight systems. Hence, they have the capacity of displaying intense black levels. Compared to conventional LCDs, these displays are also lighter and thinner.
Edge Lit or Local Dimming
Local dimming is a feature whereby individual LEDs in the LED display TV can be controlled for their brightness and intensity. This produces high contrast along with high shadow effects. However, when it comes to purchasing an LED TV, there are many choices such as full array with or without local dimming and edge-lit with or without local dimming. In the case of full-array, the LED display is lit entirely throughout the screen surface. In the case of edge-lit the lighting is only around the edges, facilitating a thinner screen size as well.
The LED display TV is available in both thin and slightly thicker versions. The thicker versions offer full-array lighting, which provides spectacular picture quality while the thinner versions are visually stunning and have edge-lit features. The thinner versions are conducive to wall mounting.
