Discussed is an apparatus and a method of manufacturing a display using a micro light emitting diode (LED). A method of manufacturing a display device using a light emitting element includes providing a substrate having an individual pixel position defined by a pair of assembly electrodes; moving the light emitting element including a magnetic body on to the substrate using a magnetic chuck having an electromagnet; assembling the light emitting element at the individual pixel position using the magnetic chuck; and recovering a remaining light emitting element which is not assembled at the individual pixel position using the magnetic chuck.

Apparatus and method of manufacturing display using light emitting element

The present invention relates to a display apparatus, specifically to a display apparatus using semiconductor light-emitting elements of a few micrometers to tens of micrometers in size. The present invention provides a display apparatus comprising: a base part; a partition part having a plurality of grooves; a plurality of semiconductor light-emitting elements arranged on the base part and mounted in the plurality of grooves; first and second wiring electrodes arranged on one side and the other side of each of the semiconductor light-emitting elements, respectively; an assembly electrode arranged on the base part and arranged on the one side of each of the semiconductor light-emitting elements; and a dielectric layer arranged on the base part and arranged between the assembly electrode and the first wiring electrode, wherein each of the plurality of grooves includes at least one recess portion formed in the horizontal direction with respect to the base part.

A washing machine according to an embodiment of the present disclosure can obtain an effect that increases a drive torque value of a drive motor by appropriately changing a wire diameter of a coil and the number of turns of the coil without changing a reduction ratio of a planetary gear, a size of the drive motor, and a stacking height of a stator core. In detail, a rotational speed ratio between the drive motor and a pulsator, obtained by the planetary gear, is 3.8:1, the stacking height of the stator core is 13.5 mm to 14.5 mm, and the number of turns of the coil is 100 to 140.
