Patent number: 12253411Abstract: A micro light emitting device inspection apparatus adapted to inspect a plurality of micro light emitting devices is provided. The micro light emitting device inspection apparatus includes a carrier stage, a light guide module and a detective module. The carrier stage is configured to hold the micro light emitting devices. The light guide module has a plurality of optical fibers. Each of the optical fibers has a light receiving surface and a light emitting surface away from each other. The at least one light beam is received by the light receiving surface of each optical fiber and exits through the light emitting surface of the optical fiber. The detective module is configured to receive and detect the at least one light beam from the light emitting surface of each optical fiber, thereby obtaining at least one optical property.Type: GrantFiled: December 20, 2022Date of Patent: March 18, 2025Assignee: PlayNitride Display Co., Ltd.Inventor: Cheng-Cian Lin

Patent number: 12131961Abstract: Micro device optical inspection and repairing equipment adopting an adhesion device is provided. The micro device optical inspection and repairing equipment includes a carrying stage, an optical inspection module and at least one adhesion device. The optical inspection module is arranged corresponding to the carrying stage so as to capture image information and obtain a position coordinate from the image information. The adhesion device includes a main body and an adhesive portion. The adhesive portion is connected to the main body. The adhesion device can move to a target position of the carrying stage according to the position coordinate. The main body is adapted to drive the adhesive portion to move to the target position along a moving axis. An optical inspection and repairing method adopting the micro device optical inspection and repairing equipment is also provided.Type: GrantFiled: May 9, 2022Date of Patent: October 29, 2024Assignee: PlayNitride Display Co., Ltd.Inventor: Cheng-Cian Lin
