This invention relates to the process of correcting misalignment and filling voids after a microdevice transfer process. The process involves transfer heads, measurement of offset and misalignment in horizontal, vertical, and rotational errors. An execution of the new offset vector for the next transfer corrects the alignment.

A method of transferring a micro light emitting diode (LED) to a pixel array panel includes transferring the micro LED by spraying using an inkjet method, wherein the micro LED comprises an active layer comprising a first portion emitting light in a first direction and a second portion emitting the light in a second direction different from the first direction.

A micro-LED display and a method for manufacturing same are disclosed. The disclosed micro-LED display may comprise: a circuit board; at least one first electrode formed on the circuit board; at least one micro-LED chip bonded onto the first electrode; a second electrode formed on the micro-LED chip; a bonding structure formed by heating the first electrode and the second electrode through laser irradiation; and at least one composite resin part supporting the bonding structure.

A chip pickup system is provided. The chip pickup system includes a detector for detecting a position of an irregular semiconductor chip on a holder. The holder holding plural semiconductor chips in predetermined positions on the holder. The irregular semiconductor chip is out of the predetermined positions. The system further includes a pickup tool for picking up the irregular semiconductor chip at least on the basis of information on the position of the irregular semiconductor chip detected by the detector.

Method and system that operates on a server include a time and expense management interface for capturing time and expense reporting. The time and expense reporting is for utility distribution systems, such as electrical power distribution and/or transmission systems, cellular, telecommunications, cable TV, water and sewer, natural gas, and others. These utility distribution systems include a large number of devices or objects that are distributed across a big geographic area. In one example, the authorization to submit the invoice for portions of the mobilization work order that have completed the approval process includes only authorization to submit the invoice for those portions of the mobilization work order i) not already paid or ii) that have been previously submitted and completed the approval process. The invention helps to document time and expense for government agencies, such as public utility commissions. This documentation maybe used with setting special charges on customer invoices.
