The tech revolution has created new ways of working, sharing information and having fun. Our high-tech gadgets and devices are wonderful expansive of our intellects to which new additions are done every day. However, have you ever thought of foldable, rollable, transparent and thin displays? The very thought we are talking about is OLED (Organic Light Emitting Diode). OLED displays are designed on flat light emitting technology; which is made by placing four thin layers between two conductors. OLED uses organic carbon-based compounds that emit colored light when stimulated by an electric current. In other words, they are an offshoot of existing conventional LED technology or LCD used today. OLEDs are organic because they are made from carbon and hydrogen. OLEDs are very efficient and do not contain any bad metals, so it is a real green technology.
Nowadays OLEDs are frequently used to make displays and lighting because of the fact that they do not require a backlight like LCD. OLEDs are thinner; they emit their own light and are more efficient than LCD. OLED technology is extensively used to create displays in television screens, computer monitors, and portable systems such as mobile phones, game consoles, PDAs, digital media players, and digital cameras.
Amazing Features of OLED:
- OLED create light rather than blocking light so OLED screens have better and almost perfect viewing angle.
- OLED technology has the fastest response time compared to any other type of display, so the OLED displays does not suffer from motion lag or motion blur like LCD displays.
- They are very durable, can operate in a broader temperature range and lasts for longer duration.
- Their screens are brighter, have better contrast and faster refresh rate.
- OLED with lighter and stronger plastic substrates ditch the back light and shutter arrays, which replaces the heavier, shatter-prone glass substrates often used in LED.
- OLED consumes less power because they do not need any electronics and circuit, as required to drive the LED back light and LCD shutter from a LED display, thereby making OLEDs more efficient.
OLEDs are thin and simple; these can be used to create flexible and even transparent displays. OLEDs response time is even better than plasma and there is no motion lags or trailer effect. Blue OLEDs degrade more rapidly than the materials that produce other colors. Because of this, the manufacturers of these displays often compensate by calibrating the colors in a way that over saturates them and add a bluish tint to the screen.
Promising Future of OLEDs
At present, OLED looks ludicrously expensive to spend; almost about triple for an OLED set than a conventional LCD/LED these days, but once roll-to-roll production capabilities are scaled up the cost of spitting out an OLED panel will drop below the current generation LEDs price. With the growing market and its increased demand, OLEDs have great future. Apart from gadgets, they have applications in different industries like fabric display, fashion, automobile head units and many others. Some of the contributing factors leading to rise in demand of OLED displays are its better efficiency, consumption of less power and use of organic material for production.
