An apparatus includes: a fixed primary anchoring element, a beam mount movably connected to the primary anchoring element, a beam connected to the beam mount, a vessel mount movably connected to the beam, a vessel connected to the vessel mount, the vessel being movable along at least a vertical axis, and a control unit within the vessel. In general, the sole component includes a fluid-filled bladder and a reinforcing structure extending around the bladder. A passivation layer is formed on a side of a source electrode or a drain electrode of the array substrate which is close to the color filter substrate.
