Do you remember YOUM - the official name for Samsung's flexible OLED display? The new display technology isn't featured in Samsung Galaxy S3, but it could see the day of light on the highly-anticipated Apple iPhone 5 along with smart haptics system.

As figured by Patently Apple, the Cupertino tech giant has filed a new patent for multi-tiered haptics system. The technology is currently utilized in an array of touch-enabled devices like robotics and video game controllers. It is also used in most of smartphones, but is a quick vibration. Apple seems to take the game to next level by combining flexible OLED display technology with multi-tiered haptic system.

"A control system of a tiered haptic system may determine the amount of pressure, force, displacement, or other physical response associated with the user stimuli. For example, a tiered haptic system may distinguish between relatively light contact and a relatively heavy contact on the screen surface. In some embodiments, a tiered haptic system may perform particular tasks depending on the physical response of the stimuli," said Apple in the patent filling.

The new technology can open a gate to the future. On iPhone 5, each letter on the on-screen keyboard can pop-out from the surface of the screen. While the screen will return to normal flat level when user finishes typing and exits keyboard.

Another interesting thing that the patent indicates is possibility of a 3D display in the upcoming iPhone. According to the report, the new technology will actually allow an iGadget display to contort, as a result the user with be provided with a button, an arrow or even a geological map to physically pop right out of the screen to give it 3D depth.

The report about advanced haptics technology is not a new case for Apple as it is the third such patent filed by Apple (following first in March 2011 and another in March 2012). Just before the launch of new iPad, several reports confirmed that Apple will integrate the new touch technology in third generation iPad. However, Apple seems serious about haptic systems this time as focused on a multi-tiered system.

Do you think we could type on 3D Keyboard in iPhone 5? The box below is waiting for your comments.
