FOLDABLE FLEXIBLE DISPLAY (TRI-PHONE)

摘要

Spiral plate spring (24) is used to drive unfolding a flexible display digital device (20) for use. The display (20) consists of three parts of equal length; the area of the central part (21) is either equal the total area of the first and the second side parts (22), (23), or equals the area of any part. A groove is made in-between the first side part and the central part (21), to create a space for installing the spiral spring (24) and its drive shaft (26). Two shafts (31), (40) with four end gears are installed in two grooves in- between the sides of the display side parts (22), (23) and central part (21), the four gears to be partially embedded inside corner extensions of the display (20) side parts (22) (23). Through a set of other gears and one belt in-between the two shafts (31), (40) and the spiral spring (24), the embedded gears are driven to drive the unfold of the display side parts (22), (23).
