Abstract: A vertebral lamina supporting device is provided. The vertebral lamina supporting device includes a first supporting member, a second supporting member and at least one connecting member. The first supporting member includes a first supporting base, in which the first supporting base has a first abutting surface and a first surface opposite to the first abutting surface. The first abutting surface has at least two radially arranged first concave arc portions. The second supporting member is movable relative to the first supporting member. The second supporting member includes a second supporting base, in which the second supporting base has a second abutting surface and a second surface opposite to the second abutting surface. The second abutting surface has at least two radially arranged second concave arc portions. The connecting member is connected between the first supporting member and the second supporting member.

Abstract: A color transformer of a colorful display includes storage, a data controller and a data processor. The data controller builds a multi-dimensional color lookup table and saves the multi-dimensional color lookup table to the storage to access it freely. The data processor sends color data to the data controller to lookup the correspondent color in the multi-dimensional color lookup table to obtain the output color. By looking up the multi-dimensional color lookup table, the color transformer transfer each input color to an output color independently.
