Abstract: An AMOLED panel includes an AMOLED pixel unit, a scan driving unit and a data driving unit. The scan driving unit is coupled to the AMOLED pixel unit. The data driving unit is coupled to the AMOLED pixel unit and a voltage source. The data driving unit comprises a reference current source circuit, (N+1) mirror output circuits and (N+1) switch elements. The reference current source circuit is for providing a reference current. (N+1) mirror output circuits are coupled to the reference current source circuits for outputting (N+1) corresponding data currents to the AMOLED pixel unit, wherein N is a positive integer. The m-th data current of the (N+1) data currents is 2m times of the reference current, and m is an integer 0˜N. The switch elements are disposed in correspondence with the mirror output circuits for controlling the data currents to be outputted to the AMOLED pixel unit.

Abstract: A flexible connection unit for use in a spinal stabilization device, comprising a longitudinal member having first and second end portions and a flexible portion located between the end portions, wherein the flexible portion comprises at least one spacer and a flexible member located in a longitudinal axial channel of the at least one spacer, wherein the flexible member comprises a biocompatible metal material and the end portions maintain the at least one spacer in a substantially fixed longitudinal axial position with respect to the flexible member.

Abstract: A flexible connection unit for use in a spinal fixation device, including: a first end portion and a second end portion, at least one of the first end and second end configured to be engagable by a section of a first bone securing member; a flexible member located between the first and second ends, the flexible member permitting motion of the first end relative to the second end; and a transition area located between the first end and the flexible member, the transition area tapering in diameter from a first section of the transition area proximate to the first end toward a second section of the transition area proximate to the flexible member.

Abstract: An adjustable spinal stabilization system having a flexible connection unit for non-rigid stabilization of the spinal column. In one embodiment, the spinal stabilization system includes a flexible connection unit having a tether running through a hollow portion of the flexible connection unit, wherein the tether limits bending of the flexible connection unit. In a further embodiment the tether is pre-tensioned. In a further embodiment, the tension upon or compression of the tether is adjustable.

Abstract: A flexible spinal fixation device having a flexible metallic connection unit for non-rigid stabilization of the spinal column. In one embodiment, the fixation device includes at least two securing members configured to be inserted into respective adjacent spinal pedicles, each securing member each including a coupling assembly. The fixation device further includes a flexible metal connection unit configured to be received and secured within the coupling assemblies of each securing member so as to flexibly stabilize the affected area of the spine.
