FLEXIBLE DISPLAYS

Samsung OLED display

The near future technology will be the Flexible display which will be in the market by 2014. One of the reason for the advent of flexible screen is to make the gadgets lighter and portable. With flexible display gadgets, we can simply fold it and carry it in our pocket.

          

Flexible displays are still under R & D (Research and Development). Samsung is the leading company which is keen in unveiling flexible smart phones in the market. Flexible display uses FOLED (Flexible Organic Light Emitting Diode) which is a type of OLED (Organic Light Emitting Diode). Kodak is the inventor of OLED. FOLED is made by depositing electro luminescent organic semiconductor over flexible plastic OLED. This enables the device to be bent or rolled even when it is operating. Since OLED contains organic chemical compound, it emits light when electric current flows through it.

PROS:

OLED screens are slimmer and eye smoothening. These screens provide better viewing experience.

OLED can provide brighter, crisper displays on electronic devices.

OLED create their own light as opposed to LCDs which require a separate light source (backlight)  and hence they use 20% less power than the conventional LEDs and LCDs used today.

Since they can be rolled, it provides good portability.

OLEDs can be refreshed in microseconds in contrast with LEDs which takes few milliseconds, it provides flicker free display in near-eye applications resulting in smooth display with high dynamic motion video.

CONS:

These displays last only for shorter lifespan. The display may lose efficiency and brightness because of the stress developed during bending.

They’re prone to sunlight effect. That is, the display can’t be seen clearly in direct sunlight.

They’re prone to water as it can’t even withstand small water droplet.

OLED are costly nowadays. But as the popularity and advancement increases, the price may fall rapidly in future.
