Abstract: In one example, a hinge assembly is disclosed, which may include a band torque engine having at least one bearing portion and a vertical torque engine coupled to the band torque engine. The vertical torque engine may have an opening. The hinge assembly may include a first shaft received through the at least one bearing portion and the opening. The first shaft may be rotatable along an axis with respect to the band torque engine and the vertical torque engine. The hinge assembly may include a display bracket including an adaptor portion to hold the first shaft such that the first shaft rotates along with the display bracket. The band torque engine may provide a frictional torque and the vertical torque engine may compressively engage with the first shaft to provide a vertical frictional torque during rotation of the display bracket.
