piezoelectric element drive voltage up to 300V has been a problem for its use of Sony CSL for this layer structure with a 16 way, so that you can put him at low voltage electric field gradient required for the piezoelectric element. As a result, driving voltage down to ± 9V.
According to reports, Sony's Computer Science Laboratory (CSL) recently in Open House 2010 to show off a new type of touch panel,[link widoczny dla zalogowanych], the touch panel feature is that it can detect finger on the panel touch pressure, and then make different size according to the pressure feedback. The flu panel can not only detect pressure applied to the plane direction (X axis,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych], Y axis) of the pressure, perpendicular to the plane of the Z-axis pressure can also be detected. Sony CSL integrated into the panel on the Sony Ericsson mobile phone demo. According to presentations,[link widoczny dla zalogowanych], the phone icon on the conversion speed according to different kinds of touch-pressure changes, the greater the pressure,Approximate freezing., the faster the conversion.

Sony CSL, said the panel built with pressure-sensitive piezoelectric element drive. And the use of eccentric (eccentric motor) of the mobile phone compared to its faster response. When the drive detects the input voltage, it will touch panel in the z axis vibration. Although the amplitude of only 30μm, but allows users to feel completely.
the panel to be integrated into mobile phones,[link widoczny dla zalogowanych], the size of the drive has been further reduced, a small piezoelectric element with a floor size of 30mm × 3mm × 0.8mm.

sample frame display panel using the following six FSR and two piezoelectric elements drive, which mainly concentrated in the six FSR frame on the right and the left, middle and lower parts of the three,[link widoczny dla zalogowanych], two piezoelectric elements drive the left and right border of the middle ranks.
the panel also built a velocity-sensitive resistor (FSR), the resistor is mainly to detect the Z-axis force applied to the touch, the resistance will force the change.
