OLED – How displays to change in future

Grow with Dr Prem

Be it the display of a smartphone or the screen of a television, the new Organic Light Emitting Diode or OLED technology is heading for transfiguring everything. This light-generating technology, which can be used on the bendable surface of a device, is still in the nascent stage, and scientists are working hard on it to come up with the most efficient flexible displays.

Fundamentals of OLED

Organic Light Emitting Diode or OLED is basically a string of organic cells or layers made of semiconductors materials. When electricity is passed through this series of organic films, the device gets activated and starts producing light.

Usually, the manufacturers for mounting the layers or semiconductors in the device use glass. If you have a close look at the displays of the current series of Galaxy smartphones launched by Samsung, you will get to know that OLED is inserted in between the layers of glass. However, some developers also use plastic or foil along with glass for coating these organic cells so that a flexible display is formed that would remain intact even after bending.

The light emitted by OLED is extremely thin (only 1.8 mm.). A current under 14 volts is used for regulating this light. The device is very small, easy-to-handle, and does not warm the surface of a device much. Hence, it can be used anywhere, right from a personal gadget to a large surface.

Applications of OLED

The lightweight yet highly effective OLED technology has found varied applications until now. Rockstars, who want to flaunt sequences of lighting effects coordinated with the set list can easily add OLED light panels to their outfits and control it distantly.

It is also beneficial for military use. Generally, microdisplays developed by the foremost active-matrix OLED screen manufacturer eMagin are used for military training. In fact, microdisplays are extremely reflective Liquid Crystal on Silicon device (either 1×1 inches or smaller in dimension) that are used in wireless portable headsets. As users nod their heads for looking left to right or vice versa, the visible 2-Dimensional or 3-Dimensional interface is altered.

OLED can also be successfully used in the gaming industry. eMagin is working on it. The organization is also trying to reduce the needs of looking at the display by enhancing the efficiency of the headsets significantly.

Veterinarians can also find good use of OLED technology while giving ultrasound to animals on-site. It would help them keep a close eye on the ultrasound through the headset instead of a screen.

However, the OLED is yet to triumph over a few technical impediments. After that, you will definitely get to experience a wide range of fresh and mind-blowing attributes of the technology.
