Abstract: A mending method for a display includes the steps of making a display device light to make a plurality of light emitting positions thereof shine, searching out a plurality of defect positions among the light emitting positions, providing a transferring device having a transferring surface with a plurality of miniature light emitting elements positioned correspondingly to the light emitting positions, planning a mending procedure which includes in the area the transferring surface corresponds to, choosing in chief the largest number of defect positions able to be mended at a single time according to the positions of the miniature light emitting elements and then in the area the transferring surface corresponds to, planning the rest of the defect positions according to the rest of the miniature light emitting elements, and according to the mending procedure, moving the transferring device to weld the miniature light emitting elements at the defect positions.

Abstract: A method for forming a semiconductor package is provided. The method includes forming a first alignment mark in a first substrate of a first wafer and forming a first bonding structure over the first substrate. The method also includes forming a second bonding structure over a second substrate of a second wafer and trimming the second substrate, so that a first width of the first substrate is greater than a second width of the second substrate. The method further includes attaching the second wafer to the first wafer via the first bonding structure and the second bonding structure, thinning the second wafer until a through-substrate via in the second substrate is exposed, and performing a photolithography process on the second wafer using the first alignment mark.

Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, and an assist assembly. The movable portion is used for connecting to an optical element having a main axis. The movable portion is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The assist assembly limits the movement of the movable portion relative to the fixed portion.

Abstract: The method contains the following steps. First, in a MCM system with N sub-carriers, the baseband signal blocks Xj, j=1, 2, . . . ,B are supplemented with zeros and processed with LN-point IFFT, respectively, to obtain L-time oversampled time-domain signal blocks xj, j=1,2, . . . ,B. Then, xj undergoes Q Time Domain Circular Shifts or Frequency Domain Circular Shifts to obtain Q signal blocks {tilde over (x)}j(ij), ij=1, ?, Q. Subsequently, a B×B unitary transform is performed against ( x1, {tilde over (x)}2(i2), . . . , {tilde over (x)}B(iB)). After the unitary transform, for each (i2, . . . , iB) a combination having B time-domain signal blocks is obtained as follows: ({tilde over (y)}1(i2, . . . , iB), {tilde over (y)}2(i2, . . . , iB), . . . , {tilde over (y)}B(i2, . . . ,iB))=( x1, {tilde over (x)}2(i2), . . . , {tilde over (x)}B(iB)) cU where U is the B×B unitary matrix, and c is an arbitrary constant (c?0).
