Abstract
A functional device includes in succession: a first protective film on the front face of the device, with Young's modulus (YM) E1 and thermal dilatation coefficient (TDC) CTE1, a first exterior encapsulation film, with YM E2 and TDC CTE2, an interior encapsulation film, with YM E3 and TDC CTE3, a second exterior encapsulation film, with YM E4 and TDC CTE4, a second plate on the rear face of the device, with YM E5 and TDC CTE5, E1 and E5 being similar or identical, E2 and E4 being similar or identical, E1>E2 and E4<E5, CTE1 and CTE5 being similar or identical, CTE2 and CTE4 being similar or identical, CTE1<CTE2 and CTE4>CTE5, and one film of the first exterior encapsulation film, the interior encapsulation film and the second exterior encapsulation film encapsulating the active elements; and method for producing a functional traversable surface.
